Industrial production

Bambi's silent compressor is an independent, fully self-sufficient air center created by Bambi engineers in the most advanced technologies.

BAMBI offers a wide range of silent compressors suitable for both your special task and for any standard applications where pure compressed air is required, comfort, high reliability and efficiency.

Laboratories

BAMBI compressors use special demand in cases of responsible application. Such application is found in research laboratories with unique equipment. For this, Bambi not only produces reliable systems, but also provides high-class service, as well as the satisfaction of the specific requirements of each specific application.

Medicine and stomatology

Ideally clean air, complete absence of oil pollution, low noise - these are standard requirements for modern medical equipment.

Over the years, Bambi has been developing to promote compressors in this sector, and the Bambi system fully meet the requirements of modern surgery.

Bambi compressors provide hygienically clean air and easily connect to any medical equipment.

Silent oil compressors

BB and MD series are designed for those users who need compressors with extremely low noise levels, maximum efficiency and calculated for long-term trouble-free operation.

Although the compressors of both episodes have a power module using oil, for the MD series, unique piston rings have been developed, excluding oil from entering compressed air, which allows them to be used in medicine, dentistry and laboratories and makes them the only silent compressors of this type of market.

Compressors of these series are standardly equipped with an internal coating receiver, a silent check valve, a 10-mkm output filter, a pressure regulator, and many other devices.

BB Series

These compressors are the most inexpensive all Bambi compressors. They have the same pump block and various receivers, pump blocks can be for greater performance. To the peculiarities of this series, we will draw an extremely low noise level, like a modern refrigerator. Pumps of these compressors are placed in a metal casing, the crankter is filled with special oil. The engine and pump itself hangs on the springs inside the casing, taking the oil through the combined crankshaft and the motor shaft. Thus, the lubricant of all parts of the compressor occurs, the oil is additionally sprayed into the area of \u200b\u200bthe casing lubricating the cylinder and the piston through the air intake.

The piston of the copressor does not have an oil-chain rings to increase reliability and simplify the design. Conclusion with these features compressors BB passes oil into compressed air, spending it from the crankcase. Over the oil level must be monitored, especially if the compressor works for a long time. The fact is that the oil consumption is strongly increased with increasing pump temperature, you can monitor the oil level through a special transparent window. Comp served in this series are not recommended for use during a full working day and, moreover, around the clock. They will suit you if you use a compressor for power, such as a pneumatic dispenser or for rare use.

The BB series is not suitable for tasks requiring air and condensate air. If the comp servers will noticeably warm, the particles of oil fall into the compressed air and fill the room with a characteristic odor.

MD Series

This is a series of raw compressors similar to BB compressors, but with a significant advantage - they do not let oil in the air. That is, with a low noise and vibration and durable design, they do not require regular oil topping. Pumps are passed into the air as little oil that such compresents can be used in dental clinics, the patient does not feel the smell of oil.

HT

Compressors of this series are oil-free compressors with low noise, compared with ordinary similar compressors. The noise in its spectrum is not at all like a noise from the refrigerator, more like a noise from an ordinary compressor, only noticeably quieter. These compressors do not produce oil into the air and do not require maintenance at all, except for the condensate drain from the receiver. For this you have to pay less long service life. These compressors are not recommended to be used to work throughout the day, since they have no compulsory cooling pump. A version with a twice speed of crankshaft rotation for greater performance (-2p) is available, for which it will have to pay the service life and noise level.

VT and VTS Series

This series refers to the class of productive industrial piston compressors. Compressors of this series can work around the clock, thanks to the forced cooling fan. All components of the compressor have exceptionally high reliability. Compressor pump is oil-free, so the compressor requires a minimum of service, in particular, condensate drain. All models can be equipped with a condenser air dryer to produce absolutely dry air. Thus, compressed air is obtained, absolutely clean from oil and moisture. VTS models have a sound-absorbing casing, a slightly reduced noise level from powerful pumps.

Many types of technological equipment require compressed air. Compressors for this purpose, including silent, is produced a huge amount. The task of choice suitable in the parameters of the model in practice is much more complicated than it may seem at first glance. Let's try to figure out which compressors are and how to choose the optimal model, on the example of British silent Bambi compressors.

The choice of compressor, as a rule, begins with the choice of its type. For equipment with low air intake, traditional piston compressors with a small and medium efficiency electric motor are suitable: oil and oil-free. Oil models are usually quieter and are subject to smaller wear. The pump of the oil compressor is usually installed in a metal casing, filled with oil, which reduces noise to the level of modern domestic refrigerator. In this case, such a compressor provides sufficient performance: about 50 l / min. With a pressure of up to 8 bar. It is worth noting that the performance can be increased by cascading two or more POMP, the noise level will increase slightly: by 2-3 dB.

Oil compressors (Fig. 1) are widely used in cases where it is necessary to provide silence and comfort in the working area, while they are very reliable and inexpensive. However, the presence of oil in the crankcase imposes some restrictions on the application of the compressor, and is due to the fact that the oil, albeit in minor doses, but still falls into the compressed air. Standard air filter (Fig. 2), which completed all compressors, delays particles of oil to a large extent, but it does not guarantee absolutely clean air at the output. A small oil content in the air is absolutely harmless to industrial applications, but it may be a problem for medical equipment, optical devices and some research laboratories. In addition, oil compressors require constant control of the oil level (Fig. 3) and periodic maintenance associated with its regular, as a rule, annual replacement. For this reason, they are not recommended to use with fully automated equipment, where the staff participation is completely excluded.

Fig. 3.

In such cases, it is advisable to apply oil-free compressors. In the model row of Bambi, they are represented by the series HT and VT. Pump such compressors has a capacity from 100 to 300 l / min., But performance is significantly reduced with an increase in working pressure. The pump does not require control and maintenance, oil entering the air is completely excluded. At the same time, compressors work relatively quiet: noise level is only 53 dB. Compressors of the NT series (Fig. 4) have a compact size, and the largest receiver is 24 liters. This makes them optimal for equipment with a small consumption of air.

Fig. four.

The VT series (Fig. 5) is represented by more productivity models - from 120 to 440 l / min. At idle. They also do not require maintenance and are designed for long-term trouble-free operation. These are large industrial compressors, and they can only be called silently conditionally and only in comparison with most such systems of other manufacturers. The definition of "low noise" will be more correct, given their noise level of 72-76 dB. And still, this is a fairly low noise level for compressors of such performance, and it is achieved due to the unique dual pump module with the V-shaped arrangement of working cylinders (Fig. 6). The compressors of this series are equipped with a special electric valve that reduces the pressure in the compression chamber after the system is turned off. This provides a smooth start of the engine, reduced the load on all mechanical parts of the pump and extends the service life of the compressor. It is possible to equip the compressor with an automatic condensate drain system into a special container (Fig. 7).

If the pneumatic equipment is required dry air, then any model of the VT series can be equipped with a unique air drying system. The air is first cooled (Fig. 8), then micro water drops are delayed in the dryer filter (less than 0.01 microns). In this way, 99% of moisture is removed before the moisture unit starts. The built-in microfilter removes all possible residual pollution. The drying module is made of stainless steel and self-cleaning with each compressor operation cycle, so it does not require any maintenance.

So, in choosing a compressor, you should always find a compromise between productivity and noise level and take into account the requirements for clean air cleanliness. There are piston compressors silent, productive and giving perfectly cleaned air. First of all, these are special medical oil compressors Bambi Series ML) (Medicine and Dentistry - Medicine and Dentistry), which have the highest characteristics with a minimum noise and compactness. The series is designed for cases when especially clean compressed air and silence indoors are needed. "Heart" MD compressors (Fig. 9) is an air module 175, which is 50% more productive than other systems with the same level of noise. This is the only oil compressor unit in the world, which has a special piston with unique piston rings, eliminating oil entering compressed air (Fig. 10). Since the MD series compressors have a sound level of only 40 dB and there are almost no vibration in them, they can be placed in close proximity to staff: they do not create any noise problems for people.

A second solution providing simultaneously the absence of oil and a low noise level is the use of sound-absorbing casing. For example, in a small HTS5 model, due to the casing, the noise compared to other NT series compressors is reduced by 7 dB and is only 46 dB - this is a record low for a oil-free compressor.

A similar solution is for higher performance compressors. In cases where the high performance compressor must be installed next to the work site, the VTS series is recommended. The models of this series are based on the VT compressors, but are equipped with a casing that significantly reduces the noise level (Fig. 11) and allowing it to be better to enter the device into the interior of the laboratory or workplace. The VTS compressor housing is equipped with a ventilation system with temperature sensors, cooling all running parts, so that with the use of casing, this series has not lost in reliability and operational characteristics.

Any silent or low-noise piston compressors consist of a pump with an electric motor and a receiver. Most likely, you can already determine which type of compressor you need. It remains to figure out what kind of receiver volume you need and what the pump performance should be. Choose a model with the most suitable parameters is quite simple.

Calculation of pump performance

Piston compressors are designed for short work with a specific intramane-use coefficient or a working cycle, usually not exceeding 50%. That is, the pump should relax as much or longer than swing air into the receiver. The total average air consumption of all connected consumers must be at least two times less pump performance at operating pressure:

To IN - the utilization rate of each consumer connected to the compressor;
To the saw coefficient of the compressor: this value is individual for each compressor.
All Bambi compressors are 0.5. In this case, the pump will work in the right mode, and the pressure at the compressor output is guaranteed not to fall below the desired for your pneumatic tool.

For example, you want to connect a pneumatic river. In technical specifications it is indicated that it consumes 10 CFM or 280 l / min. With a pressure of 6 bar. And the installer will work with it on the assembly line, spinning the screws in the body of the product. The installer receives a new product every 5 minutes. And twists 10 screws 2 with each. It turns out that the screwdriver consumes 280 l / min. Only 20 every 5 min., and an average of 280x20 / 300 \u003d 18.7 l / min. We will make a small supply, rounding this value up to 20 l / min. It turns out that we need a compressor with pump performance at least 40 l / min. With a pressure of 6 bar. These parameters do not fit compressors with a single pump series, the software is suitable, for example, the MD75 / 80 oil compressor or oil-free NT15-24.

When working with piston compressors, it is necessary to remember that any, even the most reliable model, working more than the installed limit or continuously, is inevitably overheated. Overheating, depending on the extent, Veda! To increased wear of the cylindrophone group, and the compressor can quickly fail. If you have not installed exact compressor working conditions, then the productivity supply must be made as much as possible.

Calculation of the volume of the receiver

The volume of the receiver (Fig. 12) affects the reserve of air, which you will be enough for continuous operation of the tool without falling the pressure below the working:

where g n is the consumption of uncompressed air;
t NPN - the required time of continuous operation of each consumer connected to the compressor;
ΔP-Range of pressure adjustment in the receiver, bar.

The pump compressor is configured in such a way that the engine stops its work when the pressure in the receiver is reached 8 bar and begins to swing air when the pressure will drop to 6 bar. The six bar is usually enough for any tool used when working with electronics, and it should be calculated on this working pressure.

Updating clarification, you can put that when you have 100% the receiver, you have an air stock in two volumes of the receiver until the pressure falls below 6 bar. The air volume consumed by your pneumatic tool during continuous operation must be less than two volumes of the receiver. If you work at a smaller pressure, then the air stored in the receiver will be more.

For pneumo-separated from our example, the receiver is required not less than 280x20 / 2 \u003d 47 liters. For this time, you need a large receiver, for example, Bambi BB50D, MD150, or any compressors from senior lines - VT and VTS. However, if the screwdriver worked at a pressure of 3 bar, there would be enough receiver in 19 liters.

We hope that the data in the article recommendations on the selection of the compressor will help you understand the variety of pneumatic equipment parameters and select the optimal model for your task. This will not only save your money, but also will provide a long and reliable operation of the compressor, and therefore the equipment itself.

Noise - one of the most important parameters of the compressor designed to work in inhabited rooms. For production facilities for the production of compressed air, productivity and maximum pressure are more important, but the level of noise produced is important for them. Designers are constantly working on a decrease in equipment noise, creating silent models for medicine, aeration of aquariums, hobbies and accurate industries.

Types of compressors

By a method of compressing air, compressors are divided into three main types:

piston;
rotary;
membrane.

The most common and affordable piston compressors and are louder than all. This is due to the features of their work:

a large number of moving parts;
opening and closing valves;
air passes through the channels of the alternating section.

Special design solutions are applied to reduce noise, such as oil-free quiet compressor. Another direction is to increase the number of cylinders. Two-cylinder models have smaller sizes of the piston group and are less noisy.

Membrane devices have fewer moving parts, create a smaller pressure drop and therefore constructively the most silent.

Rotary (and their subspecies - spiral) compressors also have a minimum of moving parts and create an average noise level. They are complex in manufacturing and are designed for a permanent job. Noise is the determining selection parameter for many consumers using low-noise units. These include:

medical institutions;
research laboratories;
superval production.

Medicine requires truly silent air and liquid compressors. This is achieved either a decrease in productivity and growth of dimensions, or the device in the neighboring room.

At ultra-precise high-tech production, silent compressors are used to drive pneumatic tools.

A long stay under high noise leads to rapid fatigue, reducing attention, development of diseases of hearing and nervous system.

Energy is spent on the creation of a high level of air noise and concomitant mechanical oscillations (vibrations) energy. Therefore, in addition to direct harm caused by the air noise, animals and accurate technique, noise also leads to excess energy costs, reducing potential performance. Compressor silent or compressor productive? This question is a modern technique gives an answer. Compressor and silent, and productive will cost expensive.

Rotor

In such structures, the air is compressed, passing between parts of complex profiles of two or more constantly rotating aunts. They can be two subspecies:

screw;
spiral.

Such systems are sufficiently silent because they do not have rubbing or constructing parts. Rotary compressors allow you to achieve high pressure values, they have a high motor, reaching a few hundred thousand hours.

Their feature is a long-term warming up to operate. Therefore, such circuit solutions are used where the supercharger should work continuously in large technological installations, large centralized compressed air distribution systems.

Design and manufacture of conjugated profiles of working screws costs expensive, such superchargers are several times more expensive than piston. Service and repair also cost large sums.

Membrane

Such silent structures are also called diffusion. Their main working organ-elastic membrane, which is given to the actions of the rotating eccentric. Compared to piston systems, the number of moving parts is minimal, the elastic membrane absorbs and extinguishes the oscillations of the sound frequency. Therefore, the noise level of such superchargers is minimal - from 30 DB in models for operating and garbage production. For rumor their work is felt as a quiet sigh of a child.

The simplicity of the membrane type device provides its high reliability and a significant motor test - it reaches hundreds of thousands of hours. However, they develop a small pressure to three atmospheres. Performance is also small.

Piston

Such structures are well worked out, inexpensive in production and easy to maintain. Their characteristic features:

ability to multiple / off;
a large number of rubber and obsubbing parts;
low cost in production and maintenance;
high noise up to 120 dB;
small motor test (up to 10 thousand hours);
leaning to overheating.

The combination of these properties makes the unit indispensable in small workshops, which use compressed air, and the noise can be patient.

Piston silent compressors are significantly more expensive than ordinary

Principle of operation

The physical principle of creating a working pressure for all types of compressors is one. Air (or another working medium at atmospheric pressure falls through the inlet nozzle into the working chamber. The volume of it in some way or another is reduced, the pressure is increasing. The working medium is leaving the working chamber through the outlet nozzle. The air portion is again started in the chamber pressure, the cycle is repeated.
Depending on the type of supercharger, this principle is implemented with the following differences:

Piston. The input and outlet nozzles are overlapped with valves, insulating the working chamber. The entrance opens when the new air portion is launched, the output is at the end of the compression cycle for the production of a compressed work environment in the highway. Compression occurs due to the progressive movement of the piston, which reduces the volume of the cylinder.
Membrane. Also has nozzles acting similarly. The change in the volume of the chamber occurs due to the deflection of the elastic membrane made from the rubberized synthetic tissue or from the polymer film. The center of the membrane rests on the rotating eccentric, which periodically deforms it. Back the membrane returns under the action of its own elasticity.
Rotor. The working chamber does not have a constant configuration. This conventional passage between quickly rotating towards each other spiral or screw shapes. The augers capture the air and push it on among themselves, just like the screw moves meat in the meat grinder from the neck to the knives and grille. There are no valves as such, the air is held by the constant movement of the auks.

To create low noise and silent piston compressors apply a number of approach. It:

the use of special materials absorbing noises and vibrations;
more accurate processing of conjugate parts;
careful acoustic calculation of the design, eliminate the noise of streamlining and possible resonant phenomena;
an increase in the number of cylinders simultaneously with a decrease in their size;
replacing noisy cast iron piston rings on fluoroplastic, not needing lubrication.

As a result, it is possible to bring the level of air radiation to acceptable values \u200b\u200bof 35-40 dB. Such a piston supercharger can be considered almost silent

Aquarium pump

After the refrigerator compressor, these are the most common devices that work in close proximity to humans. They are designed to improve the supply of fish and other pets living in aquatic environment. For equipment and arrangement of the aquarium, the following types of devices are used:

piston;
membrane.

Piston provide better performance per unit power. Their specialists are advised to apply large containers for aeration.

Membrane type pump performance is significantly lower, it is suitable for small aquariums.

Aquarium models are specifically designed as silent. The level of acoustic radiation of membrane devices reaches medical requirements in 30-32 dB-such aerators can operate in bedrooms. If the passport noise level of the compressor over 35 dB- aquarium is better to put in the kitchen or in the living room.

Compressor selection parameters

The main parameters for which buyers choose silent blowers, as follows:

working pressure, (atm. or bar);
performance (in liters per minute);
the volume of the accumulative tank (if provided);
power, W.);
noise level, dB.

The first two parameters must satisfy the needs of the compressed air consumer, which you are going to connect to the aggregate. Engine power determines the performance of the unit. Too large power supply will mean non-production costs of electricity. The volume of the oil compressor tank should cover the air flow at the periodic switching on the blower for the paging.

The noise level must comply with the requirements for sanitary standards for inhabited premises. So, for the bedroom, operating and ultra-precision production is 30-32 dB, for residential premises - 35-45 dB.
