Pluses: Value for money

Disadvantages: The studs for which the pump is attached rust. Sensitive to mains voltage. If less than 190-200 volts, it does not turn on at all.

Comment: I took it on the market in the Moscow region in May 2015 for 7,000 rubles. In May, he lowered it into a well (18 meters). Until October, they used it in a simple mode - plugged in the plug - pumped up the containers - removed the plug from the socket. No problem. I decided not to get it for the winter, hung in the water all winter. In May 2016 he took it out for external examination. The fastening studs are completely rusted. The stainless steel body is normal. They also mounted it in an automatic system with a hydraulic accumulator and a pressure switch. The season worked well, no problem. The only remark - when there were cold evenings and at the dachas everything was turned on, it did not work due to a decrease in voltage in the network. But then, at some point in the growth of tension, it worked again. It is necessary to put a voltage stabilizer, but my hands have not yet reached. In general, for 5200, for which you can now buy it, a good option for a summer residence. Enough for two seasons. (maybe more, but you probably need to lift it - disassemble, maintain, change the studs, reluctance) I think to buy a couple, as a consumable, change the norms every two years. :-) There was a little bit of very, very fine sand in the well - it didn't affect the work in any way.

Pluses: PRICE! this is the most optimal offer on the Internet. Good performance

Comment: I don’t know why there are so many bad reviews, but we will give the same to the parents at the dacha, the performance is enough for the eyes + they are now even cheaper than 3 years ago. PEOPLE especially for you - a life hack: in order not to force the pump and extend the service life, put a check valve and immediately change the studs to stainless steel and you will be happy.

Rating: 5 out of 5

Advantages: From experience of use, I want to confirm that this pump is ideal for organizing a water supply system for a private house. 4 years working.

Disadvantages: only pluses for that kind of money.

Commentary: the sand in the well haunts that soon you will still have to buy a new one. but I have already worked for 4 years. I am satisfied.

Rating: 4 out of 5

After five months of use, the studs have rotted, so if you take them immediately change them to stainless steel. And so a good pump. It will work in the country.

Every day, the owners of private houses or summer cottages are increasingly asking themselves the question of drilling a well or a well on their territory. But in addition to drilling, it is also necessary to somehow supply the extracted water to the house, and here the owners get into a stupor, and a lot of questions arise in their heads. Which borehole pump to choose? What should be its performance? Choose an expensive model or save money? Consider the domestic borehole pump Whirlwind SN-100, because they have established themselves as reliable and inexpensive products. Over the long period of the company's existence, the model range of pumps has become very large, since an individual tool is required for each working condition.

The main purpose of borehole pumps is to pump water from various sources, for example: a well, a deep well or a reservoir. As the device operates under extreme conditions, it requires an increased degree of protection against corrosion, electric shock and abrasive materials.

Based on the above requirements, the "Whirlwind" borehole pumps have an IPX8 protection class against short circuit and electric shock, which makes it possible to use these devices at depths from 1-2 to 70 m with different contents of pollutants.

Difference of models according to the principle of operation

There are three types in the "Whirlwind" model range:

• The borehole pump Whirlwind SN 100, SN-50 is a product operating on the vortex principle. In such models, water is captured from above;
• Pumps for wells СН-90В and СН-100В use a screw grip of water and take water from the top;
• The CH-50N model uses a centrifugal principle of operation and liquid intake in the lower part.

Vortex borehole pumps are designed for the intake and supply of the most pure water with a content of abrasive particles (sand) of no more than 40 grams per cubic meter.

The device is quite simple, its working part is a flat disc with blades along the edges. This disc is placed in an annular cavity with tightly fitted ends. At the edges of the cavity there are inlet and outlet nozzles, which are separated from each other. When the disk rotates, water is captured and unwound in the cavities of the disk, after which, due to centrifugal forces, the liquid under pressure is fed into the outlet pipe and enters the consumers. During the operation of the blades, a kind of vortex movement is formed in the pump casing, which ensures continuous capture and supply of water. Due to this principle of operation, the pump is called a vortex pump.

• Pros: This type of pump provides excellent water pressure and works according to the simplest principle, and they are also the most common and budgetary ones.
• Cons: For high-quality and long-term operation, the sucked water must be as clean as possible, otherwise the device may quickly fail or lose its power. Also, such models can create significant noise from the working blades.

Centrifugal borehole pumps are used to supply clean liquid with a small content of abrasive, which should not exceed 180 grams per cubic meter.

The pump works according to the following principle: water falls on a rotating wheel with blades. After that, centrifugal forces act on the liquid, and a vacuum is formed inside the wheel, and pressure along the edges, which pushes the water with great force. The pump body is made in the form of a snail, this is done to increase the swirling of the water and increase the pressure in the system.

• Pros: This type of pump is very efficient and reliable. They can work for a long time and do not heat up at the same time, and a high pressure is provided at depths of up to 60 meters. Also, the device has overheating protection and emergency shutdown to prevent equipment damage.
• Cons: These pumps have no obvious disadvantages, and the reviews about them are extremely positive. The only drawback may be the price and quality of the parts, on which the cost of the product depends.

Screw borehole pumps 90B and 100B are designed for pumping water from wells, large reservoirs, reservoirs and even mine wells. The maximum permissible degree of water pollution can be 250 grams of abrasive per cubic meter.

Screw pumps work according to the following principle: there are two screw pairs in the device case, one of which is stationary, that is, it is a stator and is made of rubber. The second spiral is a rotor and is made of a special coated steel alloy. During rotation, friction points are formed between the rotor and stator, which create fluid pressure. The more points of contact, the higher the productivity and working pressure.

• Pros: Among the positive qualities, one can single out greater reliability and performance, as well as the noiselessness and depth of the device.
• Cons: СН-90В and СН-100В are the most expensive, because they require higher quality materials and protective equipment, since the devices are often used in polluted water bodies, wells with a high content of sand, etc.

Pump selection criteria

• Depending on the diameter of the well, the size of the pump is also selected, taking into account the fact that it must enter the pipe with a gap (at least 10-15% of the diameter of the well);
• In accordance with the depth of the well, the operating capabilities of the pump are also selected.

Advice! It is better to take a more powerful pump due to the fact that over time, the device will weaken from the abrasive agents in the water;

Important! With an increase in the immersion depth of the pump, its performance decreases;

• Regardless of the pump model, automatic protections must be present in it. For example, all models of Vortex pumps have in their arsenal a thermostat, which is triggered when the device is heated to a temperature of 110 degrees. Also, some models have clogging protection.

Borehole pumps are used to provide residential and industrial premises with water. They operate at great depths with full submersion in water over 50 meters. The powerful power plant allows water to be supplied uninterruptedly from wells and deep wells. A domestic example with high quality is the Vortex borehole pumps.

The principle of operation and types of pumps Whirlwind

The difference between the Vortex submersible pumps is the principle of pumping water into the device. On this basis, the following are distinguished:

• centrifugal;
• screw;
• vortex devices.

The centrifugal submersible pump lifts drinking water from a depth of up to 50 meters. At the same time, it copes with the concentration of sand up to 180 grams per cubic meter. The device is quite powerful and provides uninterrupted water supply. These pumps include "Vortex SN-50N".

Its structure resembles a snail. It consists of a cylindrical body and an electric actuator. A propeller with wide curved blades is connected to the drive. When submerged, the pump freely passes water into the housing and it fills all the space between the blades.

After that, the electric drive is activated, which intensively loosens the screw. The propeller pushes water from the spaces between the blades to the inner surface of the walls of the body. There is a hole that connects the body and the pipeline. The result is a pressure difference that causes the water to rise upward.

On devices of this type, special thermostats are installed, which, in the event of an overload of the electric drive, turn it off.

Screw pumps maintain the water pressure when immersed in a well or well with a depth of up to 100 m. At the same time, the immersion depth of the device from the water surface should not exceed 35 m. The design of the device allows you to work with water, the concentration of sand in which does not exceed 250 grams per cubic meter.

For the well, it consists of a thin cylindrical body connected to an electrical power plant. Inside the body there is a screw mechanism, which consists of a steel rotor (screw) and a rubber stratum (inner rubber gasket of the body with ribs). As a result of immersion to a depth, water is supplied to the chamber of the screw mechanism.

Under the action of an electric drive, the internal screw is wrapped inside the stratum. Touching together, the friction pair forms sealed spaces that are maintained until water is released into the pipeline. The next portion of water increases the pressure and throws the water mass even higher.

This principle of operation is used on the "Vortex SN-90V" and "Vortex SN-100V" vehicles.

Only suitable for ponds with a low sand content. Its maximum concentration should not exceed 40 grams per cubic meter. Such a device consists of a round flat body with two nozzles and a disc inside. The work is provided by an electric motor.

When submerged, water enters the disc chamber through the inlet. Driven by an electric motor, the paddle disk creates a vortex flow of water along the walls of the housing. After that, it is pushed into the outlet by centrifugal force.

This class includes the "Whirlwind SN 100" and the more efficient model "Whirlwind SN-50".

Model range of downhole apparatus of the "Whirlwind" type

In terms of their performance and scope of application, the following borehole pumps "Whirlwind" stand out:

• sn-50N;
• sn-60V;
• sn-90V;
• SN-100V.

The "Vortex SN-50 N" apparatus is designed to pump water resources out of wells and pits, the depth of which does not exceed 50 meters. In this case, the drilling of holes in the reservoir should be at least 10 cm. The device is suitable for working with water without impurities. In medium and heavily polluted water bodies, quickly deteriorate. The apparatus is made of chrome-plated steel. Equipped with a thermostat with a forced shutdown system.

The model has the following specifications:

• water enters through the bottom holes;
• rated power reaches 600 W;
• the head is maintained up to a height of 50 m;
• works with liquids up to + 35 degrees;
• device capacity 60 l / min.

When using a SN 60V borehole pump, you can raise water from reservoirs and wells with a depth of 60 meters and a diameter of up to 100 mm. The system uses a water supply. Made of stainless steel. Suitable for water with an admixture of abrasive materials not exceeding 40 grams per cubic meter.

The technical characteristics of the device are as follows:

• working power is 370 W;
• optimal working depth 50-60 m;
• the water temperature should not exceed 35 degrees;
• the volume of pumped out water is 25 l / min.

The immersion depth of the Vortex SN 90V downhole pump is much higher than the previous models and is 90 m. For easier immersion into the well and extraction, the chrome-plated steel body is equipped with special hooks, to which a cable or rope is attached. The optimum distance from the surface of the water mass to the device is 35 m. With a deeper placement, negative pressure is exerted on the components of the mechanism.

Working qualities of the borehole pump Whirlwind SN 90b:

• the passage of water is through the upper channels;
• power consumption within 550 W;
• optimal pumping depth - 90 m;
• the device operates with a temperature of liquids up to 35 degrees;
• productivity - 25 l / min.

With the help of the Whirlwind SN 100V pump, you can pump out water masses from mines, deep pits and boreholes. In this case, the cross-section of the hole must be at least 120 mm in diameter. Like the previous submerged model, the CH 100B is equipped with additional hook rings that allow safer use of the device when diving. The body is made of stainless and partly chrome-plated steel. Equipped with a thermal relay with the ability to disconnect in case of too high load.

Specifications:

• the upper inlet is used for water injection;
• operating power limit - 1100 W;
• the head is maintained up to a height of 100 m;
• permissible water temperature - + 35 degrees;
• the volume of pumped out liquid - 40 l / min.

Not so long ago, a model appeared on sale that provides the deepest (in the model range) water withdrawal from a depth of 135 meters. Pump Whirlwind SN-135, like previous models, it is made of chrome and stainless steel. Its productivity is 40 l / min, and the power of the device is 800 watts. For the rest of the points, the description repeats the previous model.

How to choose the right pump for you?

The first thing to look for when buying is the diameter of the device. When entering the well, a cavity of at least 10% of the well diameter must remain between the channel wall and the surface of the apparatus. Therefore, for sources with a cross section of up to 10 cm, models CH-50N and CH-60V are used. If the hole diameter exceeds 10 cm, the use of CH-90N and CH-100V and CH-135 will be optimal.

Taking into account the power of the required device, it is better to focus on the depth of the well. Numerous reviews indicate that it is effective to take a model with a power slightly higher than the theoretically correct one. Since the high percentage of abrasive substances significantly reduces the capabilities of the device.

In some complete sets of models, special filters and purification systems are built-in, which protect the mechanisms of the device from the action of sand. This option is more expensive, but has a significantly longer service life. Also, when buying, you should definitely check the presence and operating condition of the thermostat, which turns off the device when the engine reaches a temperature of 110 degrees.

How to install the Vortex borehole pumps correctly?

Correct installation of the pump will keep its performance and functionality longer. To do this, you need to adhere to certain rules. First of all, the device should idle as little as possible. Such loads can damage the device.

When deepening the apparatus into the body of water, the distance to the surface of the reservoir must be at least 4 meters. The distance from the device to the bottom is at least 60 cm. When installing the mechanism, you should not rely only on the water supply channel. Fix the ends of metal cables with a small section on the device body, and fix the free ends at the exit of the well.

Periodically, you should get the pump out of the well and clean it from the accumulated abrasive.

To provide residential and industrial premises with water far from the main water supply main, well drilling is used. In this case, the supply of liquid from a deep source is carried out by downhole pumps. This type of pumping technology is distinguished by a high pressure characteristic, continuous flow and a long service life.

Among the domestic models of devices for the well, the Whirlwind borehole pump is popular. A wide range of models and modifications of the brand allow you to choose the device ideally for the characteristics of the source.

1 Types of downhole apparatus Whirlwind and their features

Depending on the features of the application, performance and other performance characteristics, several versions of the Vortex submersible pumps are distinguished. The company produces models with an upper water intake, designed for highly polluted sources, and with a lower one, which are used in wells with clean water. Apparatus with assemblies made of steel, brass, and durable polymers are distinguished according to the materials used. Mechanical seals in such devices are made of graphite or ceramic.

One of the main criteria for the distribution of Vortex downhole pumping devices is the type of working body. In this regard, stand out:

• screw pumping apparatus;
• centrifugal submersible pump;
• vortex deep pump.

1.1 Screw type devices

The electric screw pump is a fairly versatile model. Such an apparatus can be used not only in wells, but also in wells, mine reservoirs, open reservoirs. Due to its design, the device is capable of passing liquids with a solid content of up to 250 g / cc. m. Models of this type support head up to 100 m.

The design of the screw device assumes the presence of an electric motor installed in the upper part of the steel case, a working chamber, an electric cable and an eyelet with a cable. The working chamber in screw devices consists of two elements:

• movable rotor (screw);
• fixed stator made of rubber.

The elastic stator has an internal thread. Inside it rotates, connected to the motor shaft, a rotor with an external thread. The helical threads of both elements are offset from each other. The result of this displacement is the appearance of sealed cavities in the stator during the movement of the screw. It is in these cavities that the device transports water from the suction openings to the outlet. The total head created by the model depends on the number of cavities formed.

The main advantages of this type of pump are noiselessness, the ability to pump heavily contaminated water, convenient repair or maintenance. In addition, the device can be used in both horizontal and vertical orientation, which expands the range of applications.

1.2 Centrifugal downhole unit

As in the case of auger models, the centrifugal apparatus consists of an engine compartment and a working chamber, combined in one housing. Only the design of the working chamber of the device differs. It is a volute-shaped diffuser, inside of which a wheel with blades rotates on the shaft.

During operation, the wheel rotates, the blades capture the water and rotate it in a circle. Under the action of centrifugal force, the liquid is displaced under the walls of the diffuser. As a result of the displacement, an area of ​​discharged pressure is formed at the inlet of the apparatus, which leads to the suction of a new portion of water. In contrast to this, the pressure rises under the walls of the cochlea, which ensures a high head. Selected versions can include multi-stage impellers consisting of several standard impeller discs.

In terms of sensitivity to mechanical impurities, centrifugal models are less functional. The maximum content of abrasives in water should not exceed 160-180 g / cu. m. The pressure characteristic of centrifugal devices is 50 m. They are distinguished by high productivity and wear resistance of the units. To prevent overheating of the unit, most centrifugal models are equipped with an automatic emergency shutdown system.

1.3 Vortex deep unit

In structural terms, vortex-type models are similar to centrifugal ones. The difference lies in the fact that the working disk of vortex devices is equipped with shorter blades of a closed or open type. In the course of work, the blades take water from the inlet pipe and disperse it in a circle under the action of centrifugal force. During a circular motion, the flow again enters the blades, which gives it additional rotation and strength. Vortex devices use multistage pump options.

Due to the thinner design and small clearances between the impeller and the casing, the vortex unit has a capacity of only 40 g / cc. m. Protection from larger particles is provided by a strainer installed on the suction openings. The head of the vortex apparatus is over 100 m, which makes it possible to mount it in a deep source.

Also, the advantages of models of this type include a small diameter, suitable for wells with a cross section of up to 100 mm.

Among the shortcomings, the efficiency should be highlighted with an indicator of only 45%.

2 The main range of downhole models Whirlwind

The Russian manufacturer offers customers a wide range of pumping devices for various well parameters. Among the most popular models in the series are:

The CH 50 model is a vortex downhole tool with inlets at the top of the casing. The apparatus is made of stainless steel, and the cross-section of the body allows mounting СН 50 in a well with a minimum diameter of 100 mm. The intake of liquid is made from a depth of up to 50 m. The model is based on an engine with a power of 750 watts. In a minute, such a unit is capable of pumping up to 40 liters of liquid.

The description of the CH 50 N model actually coincides with the previous model. The difference is that the CH 50 N centrifugal apparatus is equipped with a lower water intake. The technical characteristics of the device have the following meanings:

• the maximum productivity of the model is 3600 l / h;
• lifting of liquid is carried out from a depth of up to 50 m;
• the minimum cross-section of the source is 100 mm;
• the maximum temperature of the pumped liquid is 35 degrees.

With the help of the borehole pump Vortex SN 60V, water is taken from wells with a minimum cross-section of 75 mm. The body of the centrifugal device is made of stainless steel and the impeller is made of durable plastic. It is used both for supplying liquid to a home water supply system, and for watering a garden or vegetable garden. The suction of the liquid is carried out in the area of ​​separation of the housing into the motor and working chambers (in the middle part). On the top cover of the body there are lugs for the cable, with which the CH 60V is fixed in the headband of the reservoir. Specifications are as follows:

• the pressure characteristic of the device is 50 m;
• the content of abrasives in the liquid is not more than 40 g / cu. m;
• volume of pumped liquid per hour - 3000 l;
• motor power - 800 watts.

The complete set of the Vortex SN 90V borehole pump is supplemented with a thermostat and a check valve, which prevents water from getting back into the device after it is turned off. The device belongs to screw models and is suitable for work with clean water. The minimum diameter of the well into which the apparatus is mounted is 100 mm.

The main performance characteristics of the borehole pump Vortex SN 90b:

• the lifting height of the liquid is 90 m;
• device productivity - 1500 l / h;
• the motor power has a maximum indicator of 550 W;
• the adapter for the pipeline has a cross section of 1 inch.

Water in the screw pump Vortex СН 100В is sucked in through the holes in the upper part of the housing. The screw working mechanism allows you to work exclusively with clean liquid. As in the previous versions, the case is made of stainless steel. The cover of the device is equipped with cable eyelets. The powerful 1100 W motor is IPx8 rated. The performance characteristics of the model are as follows:

• the maximum performance indicator of the unit is 2400 l / h;
• the pressure characteristic differs in the value of 100 m;
• the device during operation is capable of submerging 60 m into the water column;
• the weight of the device is 13 kg.

The most productive model of the series is the Vortex CH 135. The device belongs to the centrifugal type of pumps. In addition to the well, the device can be mounted in open water bodies, reservoirs, shaft wells. Sensitive units of the device pump liquid containing abrasive particles up to 40 g / cc. m. The body of the apparatus is made of steel, and the material of the impeller is a dense polymer alloy.

The device is equipped with a motor with a power of 1800 watts. This power unit is the most powerful in the range and provides a capacity of up to 5700 l / h. In this case, the temperature of the liquid should not exceed 35 degrees, since the motor begins to overheat. In such a model, the height of the liquid supply is 135 m, and the pump itself deepens into the thickness of the liquid by 60 m. Water intake is carried out by suction holes in the central part of the body. The minimum borehole section for the apparatus is 102 mm.

Pump products with the brand name "Vikhr" have been known in Russia since 1974. At that time, the Kuibyshev Electromechanical Plant produced the first borehole submersible electric pumps. In 2000, the production was transported to China, where, together with Russian specialists, the production of various pumping equipment was established. Screw borehole electric pumps, which are also called worm or screw, are used to pump clean water from deep wells. One of these devices:

Submersible pump Whirlwind SN 90V

borehole pump, which has a maximum immersion in the well of 32 m. The distance from the bottom of the well to the edge of the body should be at least 60 cm, from the surface to the device half a meter.

Downhole products are manufactured - top-drawer pumps in cleaner water, but there must be enough fluid for long-term operation. The maximum water supply is 55 meters, a more detailed schedule can be found in the product passport.

The casing of the deep well pump vortex SN 90V is made of stainless steel. The length of the cable is 20 m, it is possible to extend it to the required length.

During operation, it must be remembered that the operation of the device "dry" is not allowed, and the temperature of the pumped out water should be from one to 32 degrees.

From the factory, the model is equipped with a rubber check valve that prevents water from flowing back into the container when stopped. But when operating the product in deep wells, a rubber valve will not work; it is best to immediately install it from metal. The standard outlet threaded hole of the check valve is 1 ", if necessary, you can install a transitional connection for a hose with a diameter of at least 3/4 ''.

During operation, it must be remembered that the smaller the diameter of the supply hose, the greater the pressure. It is forbidden to artificially reduce the diameter of the installed hose.

On the sides of the body there are special eye-bolts for fastening a steel cable. With the help of a cable, the body is immersed or then retrieved from the well.

It must be remembered that in order to avoid damage to the electrical connection of the electrical cable to the terminal box, do not pull on the cable, or even handle it when the electrical network is connected.

To prevent water hammer when air enters the chambers at the beginning of work, it is recommended to install a special device called a hydraulic accumulator.

It must be remembered that according to the requirements of Safety Techniques, during operation, it is necessary to connect the product to a network where there is an electrical fuse with a cut-off current of no more than 16A, and which is triggered when the current rises above 30 mA / sec.

During operation it does not require any special maintenance. But, if the product will be out of use for more than 10 days, you need to take it out, drain the water and dry it.

Vortex data and characteristics can be viewed in the picture.

Device

СН series constructions

The series consists of a number of models with different operating principles: screw or centrifugal submersible electric pumps.

The fundamental difference between vortex and screw products is that the working body of the vortex pump is made of a wheel with blades. This wheel is placed in a chamber with an eccentric displacement of the outer walls, when the blades rotate, they capture water in the widest part of the chamber and move it to the narrower part, which creates pressure. For what type of pumps is a very important parameter such as the speed and power of the engine: the speed of rotation creates pressure, and power is the amount of liquid ejected. The standard engine speed is 2800 rpm.

The screw deep vortex pump SN 90V differs from the vortex working body, which resembles a screw in a meat grinder. Capturing part of the liquid in the lower part, the auger pushes it upward, reaching the top, the liquid is pushed through the check valve into the supply hose with sufficient pressure to lift water up to 40 m.

Attention! It must be remembered. By virtue of its design, the creation of pressure largely depends on the tightness of the screw-sleeve pair. Therefore, the operation of such a product is allowed only with clean water, so that the abrasives of sand or solid particles do not damage the surface of the bushing mirrors.

The design with a centrifugal rotor allows the transfer of microparticles up to 15 microns. (turbid water). On the other hand, the screw can pump viscous liquids, but the paddle cannot.

The device of the borehole pump Whirlwind SN 90V

The principle of operation of the deep-well screw pump is in pushing water between the cavities formed by the rotating screw and the sleeve. The bushing is made of plastic material (metal cord rubber) a rotating screw from the electric motor drive pushes water along the rubber walls of the housing, creating pressure at the outlet

Do-it-yourself Whirlwind SN 90V pump repair

It so happens that during operation the product loses its former performance, that is, it does not produce a certain amount of water per hour. One of the possible reasons:

• Dirty water inlet holes;
• sleeve wear;
• screw wear.

If the contamination can be cleaned during disassembly, but, here, wear or malfunction of the screw, or the sleeve, is made only by replacing it. The cable may also be damaged if it exits the protective seal tube. In this case, repairs should only be carried out by an electrician.

Disassembly:

To disassemble the case, it is necessary to unscrew the four screws on the shims and the lugs with keys with a facet of 10. Remove the cover carefully so as not to damage the gasket between the body and the cover. After the cover is removed, the shaft, bushing, check valve becomes accessible for inspection.

From the top cover, carefully, without using sharp objects (only by hand), get the check valve - the rubber must be elastic, the movable valve cover and the body must not be damaged. If there are no visible breakages, then after cleaning the coking parts or the inlet openings of the grill, the product will work as before.

Device

The device consists of a pressure flange, a body of a working part, a stator body, an electric motor body.

The screw and body are made of stainless steel, the screw sleeve is rubber-metal. The asynchronous motor is placed in an oil bath, protection class IP68.

So your helper has started to dispense less water. Most likely there is a malfunction in the working parts that are in direct contact with water - this is the inner part of the body, the auger and its sleeve. It is strictly forbidden to start deep products without water, therefore, all checks should be carried out exclusively immersed in liquid.

How to disassemble the vortex CH 90V

We remove the cover, under which there is a check valve, take out the auger sleeve, after which the auger itself is unscrewed. The auger is screwed into the drive shaft on a "left-hand" thread. If the thread has acidified, there are turnkey edges under the protective sleeve.

Checking the motor

Checking the integrity of the windings includes a break test and insulation measurement.
To check the continuity of the circuit, two checks are carried out:

• circuit integrity of the phase wire and motor windings;
• insulation resistance measurement.

To do this, you need to use a multimeter, and understand the principle of operation and the device of the vortex pump SN 90V. To measure the first parameter, set the multimeter to ohmic resistance mode. Then, touching the pins of the plug with the probes, we will measure, the reading should be no more than 1 Ohm. The grounding conductor is measured by touching the grounding pin of the plug and the body. If the resistance is more than 1 Ohm, then there may be a break in the ground or phase wire in the motor winding itself, cable plug or wire.

The next check consists in determining the insulation value of the phase wires from breakdown to the case. For this, the measuring probe of the multimeter in the 200 MΩ mode is connected to the pins of the plug of the electric wire. the second probe to the body (the place of contact must be clean), the resistance during measurement must be at least 200 megohms.

After that, the operation of the engine is checked, for this it is enough to connect the power plug of the electric motor to the mains while paying attention to the noise of the bearings during operation and the stability of the revolutions. The noise from the bearings should be smooth without clicking or crunching, the rpm should be stable. frequency of revolutions for household appliances = 2800 rpm.

Inspection of working bodies

then the auger and the sleeve are inspected, they should not have significant damage and should be in close contact with each other, for this, it is enough to insert the sleeve into the auger, they should enter each other with friction.
After cleaning the parts, the assembly is carried out in the reverse order. If you are still not sure how to properly disassemble the vortex pump SN 90V, then it is best to contact a specialized center, where specialists will carry out the diagnostics professionally.

Parts washing

With long-term operation, depending on the chemical composition of the water, less and more often the body and parts are exposed to mineral deposits, and plain steel rusts.

Oxides and hydroxide (rust) are most effectively removed by hand - a metal brush and rinsing with water. Ideally high pressure rinsing (mini wash). The deposition of carbonate salts, which turns into carbonate minerals during deposition: organite, coccid, can be easily removed with dilute hydrochloric acid and a metal sponge, of course, followed by thorough rinsing.

Rubber, plastic parts can be washed in a strong solution of sodium chloride. But if you decide to disassemble it to the details, it is best to supply new spare parts, especially valves and gaskets.

So, if the assistant stopped delivering water to the mountain, having lost productivity, and you decided to repair the vortex pump SN 90V, then most likely it got dirty, most often it is a calcium deposit (limestone is popular among the people). If the plaque is not yet large and has not been coked, then you can do without chemistry and you can use citric acid for cleaning. It removes organic salt plaque well.

Well pump Whirlwind SN 90V - reviews:

What's good: stainless steel body, good performance.
What's bad: the studs hold the 2 halves of the case together. After a year and a half, there is a possibility that the body will crumble right in the well. It's amazing who came up with this - a stainless steel body, steel studs tightening. I suppose that initially the studs were made of stainless steel, but in order to save money, China offered its own version of the assembly. I also attribute to the disadvantages that it is used only for pure water. Be sure to choose a solid stainless auger, chrome plated and then wedge due to increased friction with the sleeve. Approximate service life 2-3 years. But it looks like it's worth its money.

I refer to the positive properties: the oil in the motor - this gives additional electrical properties to the windings. There are eyebolts for suspension, decent head. The store announced the cable length of 20 meters, did not check it, it turned out to be a little more at home. It pumps from a depth of 20 m. The pressure is good, about the same as the full opening of a tap in an apartment. I'm tired of constantly turning on and off the outlet, I'm thinking of purchasing an automatic system for starting the engine from the pressure in the water line. It has been working for six months, so far without any comments.

I regard the advantages of a small price, a high-quality assembly of a vortex pump cn 90v review is good, though low productivity, but I have a non-standard well - 100 m deep. I consulted the sellers, they said that this type does not work for a deep well. I use it for a set of containers. Suspension on 6 mm cable. The length of the cable when purchased was 20 m, the consultant said that it can be increased. I cut the cable near the plug, built it up, nothing, it works normally for a year and a half, no complaints. Three-core cable in rubber, silk threads and braid inside.

You can buy the SN 90V Whirlwind in specialized dealerships, or on Internet resources. In order to avoid buying fakes, it is best to contact trusted large centers where they value their reputation and you can consult with sellers online or by correspondence.
