Installation of the increase in pressure is Russian. Installations of water pressure increase. Automatic pumping installation of cascade type with a device of a smooth start of a series "Storm-C"

Enter the results of the two measurements and get the result.

atmospheric

ho - air post height before the crane opening, mm

hE - airfold height with fully open crane, mm

If measurements are performed at several points, and the testimony is obtained different, then this is a sure sign that possible reason Insufficiency of pressure on a particular plumbing or household device lies in defects of the inner wiring of the water supply. It is possible that old pipes overhaul threw rust or lime raid, And no additional equipment will change the situation - you have to change the pipe wiring.

Require from such a water supply of normal pressure - just naive

The reason for the fall in pressure can be not known for a long time or uncontrolled filters - and the implementation of the appropriate prevention once becomes places.

You should compare readings with similar parameters in neighboring apartments located at the same level - they must be approximately equal. Sometimes it helps to identify the problem that lies in a plumbing riser.

It would be nice to figure out the position of affairs in neighboring apartments vertically - how much the problem of reduced pressure affects them. With the increase in the height of the floor, pressure (in the meters of a water column) should be reduced to about the magnitude of exceeding.

And finally, if, of course, it will be possible, it is desirable to find out the pressure on the "sun beds" at home, that is, on collectors in the basement, to which risers on the entrances are connected. It is possible that the public utilities fulfill their obligations, and the pressure of the water to the stands is given normal.

It means that the area of \u200b\u200bthe problem will be localized - the owner of the apartment also becomes a "adjustment" of all troubles, which the owner of the apartment has been living below the same rising, which during the repair in his bathroom has supported the diameter of the pipe for one way or another - "so cheaper", "so more convenient and more beautiful" "So suggested by an experienced plumber" or even "everything is fine with me, and the rest do not worry me." Here you will have to or agree on a good, or take measures of administrative impact through utilities.

If the pressure is weak at the house collector - it is necessary to "seek the truth" in public utilities, since the quality of the services provided by them does not comply with the requirements. Will it be possible to achieve something - more big questionSince you can hear a lot of reasons: from requiring replacement of trunk pipelines to the impossibility of currently installing new pumping equipment in return for obsolete.

What can be done?

If all the steps taken "administrative plan" did not give results, and to ensure correct operation of plumbing and domestic instruments of pressure, they will have to take measures of technological orientation. Here it will be necessary to install this or that additional equipment. But, again, it will be naive to say that the pump to increase water pressure will be naive.

Such a measure will be effective only when water is always almost uninterrupted, but its pressure is not enough to operate home appliances. For example, the owner of a private house connected to the highway in which the pressure is constantly observed not higher than 1 - 1.5 bar, it will be completely able to install the pump at the entrance to the house or even before the water-based point that requires higher indicators. To some extent, it is permissible in the urban high-rise building, but again - with a stable supply of water, but with a "deficit" of pressure.

If the "failures" of the head reach out before the upper floors often marked the complete disappearance of water from the cranes, the increasing pump does not justify itself. First, he needs to "rely on" to the minimum allowable pressure for this model in the pipe in order to issue the desired value at the output, and it cannot create anything from the void. Secondly, increasing pressure, the pump necessarily creates a certain vacuum behind. If the pressure is lacking open on any lower floor, the crane turns into a "hole" through which air can be suited. The pump will try to try to pump air, and at best, if it is equipped with a dry-running protection system, it will simply be constantly turned off, well, and if not, it will quickly be quick. And thirdly, somehow improving the position in my apartment, the owner of the pump involuntarily worsens the situation in the neighboring.

What is the way out? There are several of them, but not everything will be easily accomplished.

1. Install a pumping station running automatically, desirable - with a hydro-accumulating membrane tank of the maximum possible volume. The main element of such a station is centrifugal pump self-suction type, that is, capable of independently, even with a "zero" pressure at the entrance to raise water from a certain depth (for example, from a base collector or an autonomous source) and create a very significant pressure at the output.

Incoming usually in the pressure switch station, the pump switch will ensure the inclusion of the pump motor only when the pressure drops in the home (apartment) plumbing below the set level. The accumulating tank will create a reserve supply of water, which will also be under pressure and spent in cases where water supply in the highway is temporarily interrupted.

Thus, the pumping station lifts up the water, and creates the necessary pressure in the system, and provides a certain supply of water. The greater the amount of the accumulatory tank, the less the pump will be turned on.

The solution is excellent, one can say - optimal for private households, but in multi-storey buildings with it there may be a lot of difficulties. If the pressure in the risers is weak, then many residents of the upper floors suffer from this. If they become to leave the position in this way, the present rivalry "per jet" will grow up in the house, since the total amount of incoming water is still insufficient. Again, the same situation mentioned above - the suction of water from the pipe will lead to implanting with all the ensuing consequences. Inevitable on this vone scandals and proceedings, "denominations" to each other into operational organization or to "Vodokanal". And the installation of such a station without the knowledge of public utilities may well end in a decent fine, since the equipment makes an imbalance in overall work plumbing system at home.

There is another limitation: self-priming pumps are usually limited in depth (in the case of a high-rise - height) of water lifting - about 7 ÷ 8 meters. That is, for the first second floor - is suitable, the third is already with the stretch, and above - it is unlikely to cope.

2. Install in your home the volumetric non-valve reservoir so that it is constantly replenished at the clock of normal water supply, even with insufficient pressure. The simplest float valve will not allow the overflow of the tank.

If such a capacity for at least 200 ÷ 500 liters can be installed at the ceiling height, then water will be or sick from it to flow to the water disposal points, in front of which the usual compact pressure increase pumps can already be installed, or the ability to mounted on a total outlet of the capacitance Pump, power and performance of which will be enough for all consumption instruments. Alternatively is a compact pumping station with a low volume hydroaccumulator, which will already be powered by a cumulative tank. In this case, the reservoir can not be raised up, and find it most convenient for its existing conditions.

The main obstacle to the implementation of such a project is the closest urban apartment: to establish not even the largest container is simply nowhere. Again, this output is seen optimal for a private developer.

However, it is possible that it will be possible to cooperate with neighbors who also have a similar problem to establish a collective cumulative Buck Large capacity, for example, in the attic room at home. The scheme will be the same - the water comes to each apartment, and then the owners themselves solve themselves, at what points they need to install the rising pump.

Possible solution solving problem - with the installation of a collective accumulative tank

3. The third option also implies cooperation - this is an installation on the assembled means of a powerful pumping station with an impressive accumulative tank and a hydroaccumulator so that the power and performance of the equipment is enough for the entire riser. Thus, in the basement it will be possible to have a significant non-variable and under pressure a stock of water, and all tenants will equally receive it in the desired quantity and with the required pressure.

It is clear that it is easy to say, but it turns out very hard, as persuading people is extremely difficult. Nevertheless, examples of such a collective interaction of residents of the house - abound.

Now that the main possible cases Application of pumps that increase water pressure can be referred to equipment survey.

Pump selection to increase water pressure

So, if the situation can be fully fixed only by installing the pump to increase water pressure, then you need to know how to choose a similar device.

All pumps of such a class can be divided into two large groups - these are devices with a dry and wet rotor.

• Pumps with a wet rotor - more compact, less noisy, do not require any preventive workSince the lubricant of all rubbing parts is provided by the pumped liquid. They are installed directly insert into a pipe, for example, in front of a household device or a water-based point, and no additional fasteners require.

Typical representative of pumps with "wet rotor"

The lack of them is low performance indicators and an additional water pressure. In addition, there are limitations on the installation method - the axis of the rotor of the pump electric drive must necessarily be located in a horizontal position.

• The pumps with a dry rotor can be immediately distinguished even externally due to a pronounced asymmetric shape - made in the direction of the power bloc, which has its own air cooling system - located on the axis of the fan impeller. Such a layout most often assumes an additional console mount of the device to the wall surface.

Pumps with a "dry rotor" typically require additional mounting to the wall

Such devices usually possess higher operational characteristics, and when proper choice And the installation is sometimes able to "serve" several points of water intake at once.

The pumps with a dry rotor require regular lubrication of the friction nodes, and when working can be created, though small, but still tangible noise - this also needs to be considered when choosing a place of installation.

In general, the instruments of such a class of both types and on the device, and on the principle of operation and according to the rules of installation are very similar to circulation pumps that are embedded in the contour autonomous System Heating. In order not to repeat, the reader who is interested in these questions can be sent to the appropriate publication.

What you need to know about circulation pumps?

These compact devices provide a stable movement of the coolant along the contours of the heating system. About the device, the calculation of the required operational parameters, choose and install read in a special publication of our portal.

The root difference is that circulating pumps, as a rule, work in constantly mode, while the heating system is involved. The instruments designed to increase the pressure in the plumbing, such a mode is not required - they should only work if necessary when need to provide pressure.

There are two approaches to solving this issue.

• Some inexpensive pumps have only manual control - that is, the user includes them independently as needed. This is definitely not the most successful approach, given the forgetfulness of some people. In addition, if the device, for example, provides work washing machineThe water fence for washing and rinsing is performed periodically, in accordance with the program, that is, most of the cycle of the efforts of pumping equipment are not required.
• The optimal solution is to install a device equipped with a flow sensor. The launch of the pump will be made only when the crane is opened and, naturally, in the presence of water in the pipeline. It will unload the device from unnecessary work, and will prevent its overheating or brave from "dry stroke".

The flow sensor can enter the pump or purchased additionally. It is always installed after the pump along the movement of water.

If the water pressure in the water supply is unstable, that is, it may be normal, but in certain periods becomes insufficient, it is optional, but a very useful addition may become a pressure switch that is installed at the inlet before the pump.

Useful addition to the connection scheme - Pressure Relay

In this case, the power supply circuit is switched through the relay, which can be configured in such a way that it triggered and turned on the power of the device only in case of insufficiency of pressure in the system. With normal pressure parameters, the pump will not be turned on even after the flow sensor is triggered.

When choosing a pump, the necessary difference is necessarily taken into account on which the pressure should be lifted for the correct operation of plumbing or household appliances. It is not necessary to wait for the "proven" values \u200b\u200b- usually this parameter lies within 0.8 ÷ 1.5 bar (8 ÷ 15 meters of water column).

If it is purchased for a hot water supply pipe (there are such situations), then its characteristics must correspond to the operating conditions at elevated temperatures of the pumped fluid. Usually such information is indicated in the passports of products.

An important parameter is the productivity of the device - the amount of water pumped into a unit of time. Performance should be higher than the average consumption on the consumption point in front of which the equipment is installed.

When choosing a model, definitely, it is worth a preference to "authoritative" brands, specifying how accessible in your region service maintenanceAnd what warranty obligations apply to this device.

Several popular high-quality models are given in the table:

Selection of pumping station

So, the second option cardinal solution Problems of ensuring normal water pressure is the installation of a pumping station.

This device is a superficial centrifugal self-priming pump. It can be an ordinary or equipped injector - this technological addition significantly increases the possibilities of the pump on the rise of water with a significant depth, but, however, makes his work more noisy.

Pumping station A built-in membrane type hydroaccumulator can have already, or this element of the required volume is purchased separately. Required condition - The presence of pressure relay, but in this case it is already installed after the pump itself - when the installed pressure threshold in the hydroaccumulator is reached, the power of the power unit is turned off.

The working pressure in the hydroaccumulator is always somewhat excessive - it is calculated in such a way that the correct operation of all plumbing and household devicesAnd at the same time a certain reserve remained. As the water consumes, the pressure drops, and when it comes to a certain lower boundary, in advance by the manufacturer or the user itself, the relay closes - and the pump again works out the water replenishment cycle to the upper threshold.

In fact, the pumping station does not simply increase the water pressure - it itself creates in a closed home system of the water supply system and constantly supports at a given level. And the presence of a hydroaccumulator makes it possible to hope for a reserve supply of water in the event that suddenly the feed will stop from the external source (main network).

The flow sensor in this case is not required - the pump reacts not to the current water consumption, but to the pressure level in the accumulating tank.

As a rule, equipped with pressure gauges - so that it is more convenient to conduct visual control of work.

Installing the pumping station is much more complicated than the usual rugging pump. It is better not to do this question yourself, but to invite the relevant specialist.

When installing, it should be noted that there are practically no silent pumping stations. It means that it is necessary to provide a place that, firstly, was at the entrance to the house or in the apartment, and secondly, it would provide the necessary noise insulation for residential premises.

The hydroaccumulator can be very small ...

The hydroaccumulator included in the pumping station can be completely small, literally into several liters. However, it should be remembered that won in compactness, you can lose the duration of the operation of the device and in the consumption of electricity - the smaller the volume of the tank, the more often the pump installation will be turned off, the faster it is consumed.

Nothing prevents the desired volume hydroachamor to purchase - they are sold separately. For two people, there is usually enough tank for 24 liters. For a family of 3-5 people, a 50 liter hydroaccumulator is already required.

Well, if it allows free space, and in the supply of water from urban networks, interruptions happen, it does not hurt and the non-variable cumulative tank with a float valve - the pumping station will take water from it. This scheme has already mentioned above.

Optimal solution - Pumping station takes water from a voluminous non-pressure cumulative tank

Since the pumping station is usually installed to ensure the operation of the entire water supply network. frequent home Or apartments, when choosing a model, you must pay special attention to the pressure created by it and on performance. It will be not enough to use if, taking into account the height and remoteness of the water-based points, the pressure will be insufficient. In the practice of private home ownership, it may be, for example, a garden crane through which irrigated pricework. Therefore, it is necessary to navigate when selecting the most remote in the height and length of the point. If it is just mixers, then they will be sufficiently pressure at 10 ÷ 15 meters (1 ÷ 1.5 bar). In the case of an installation of technicians requiring special pressure parameters, they are taken as the basis.
