What will an additional receiver give to the compressor? Air receiver for compressor

During construction, installation and finishing works Pneumatic tools are widely used. Compressed air is used to operate pneumatic tools. Its production is carried out using compressor units. One of the main components of the unit is the compressor receiver.

Why do you need a receiver in a compressor?

A receiver is a container for storing liquids or gases during compressor operation. The device performs the following tasks:

• Accumulates the working mixture during compressor operation.
• Delivers compressed air to one or several consumers.
• Regulates the pressure of the working mixture at the outlet of the compressor.
• Accumulates and removes condensate that forms.
• Helps reduce vibration, noise and load during compressor operation.

The compressor receiver is made of high strength material. To store liquid and gaseous substances under a load of up to 2.0 atmospheres, containers made of high-strength plastic and rubber are used.

To store substances under a load of over 2.0 atmospheres, metal containers are used. The material used for them is steel with the addition of special additives. These additives increase the strength, anti-corrosion and thermal resistance of steel.

The basis for the future receiver

To make a receiver for a compressor with your own hands, use a fire extinguisher or a gas cylinder. Gas containers are considered the best option for making a receiver. The advantages of gas cylinders are:

• spacious volume (up to 100 l);
• light weight (from 30 to 70 kilograms);
• ability to work under high pressure.

Gas containers are tested under loads of up to 25 atmospheres. They are used for storing and transporting various gases and liquids. To prevent leakage of the gas-air mixture, a valve with reliable gaskets is used in the neck of the cylinder.

The disadvantage of a gas cylinder is the lack of a tap for draining condensate. Some experts consider this a significant disadvantage.

Advice: Condensate draining must be carried out at least twice a year - in spring and autumn.

Other experts do not see any difficulties in this circumstance. To remove condensate, open the shut-off valve, invert the container and drain the condensate.

Required tools and materials

To manufacture a receiver for a compressor, the following equipment is used:

• cutting tool;
• vice or welding machine;
• adjustable wrench;
• sledgehammer or hammer.

Attention! When cutting a container with a grinder, first make a longitudinal cut along the length of the container. Then transverse cuts are made. After this, cut off the upper or lower part. Changing the order of operations can lead to sudden depressurization.

A grinder is used as a cutting tool. As a last resort, use a hacksaw.

The vice is designed to fix the cylinder and prevent it from turning when removing the valve.

An adjustable wrench is used to unscrew the valve lock nut.

A sledgehammer or hammer is intended for beating off the cut parts of the vessel and tapping the valve when unscrewing.

The valve screws are cone-shaped. This form of thread ensures maximum tightness of the cylinder. Unscrewing a valve with such a thread requires a lot of force. To increase torque, the wrench handle is extended using a rectangular or round metal profile.

Advice: Instead of a factory valve, you can use a regular ball valve of the appropriate size.

Materials used:

• two crosspieces with M15 thread;
• gearbox with pressure gauge;
• safety valve;
• ball valve – 3 pcs;
• rubber hose.

When making a receiver for a compressor with your own hands, the parts used are connected in series to each other.

How to make a receiver with your own hands

The receiver is assembled in the following order:

• Clamp the bottom of the vessel in a vice.
• Using an adjustable wrench, remove the valve.
• Remove any remaining gas in the container.
• Remove the cover with the hole from the locking mechanism.
• Clean the container outside and inside from rust and dirt.
• Screw on the cap with the hole from the locking mechanism.
• The surface of the cylinder is cleaned of rust and dirt, primed and painted.
• Insert the adapter and secure the first cross.
• A safety valve is attached to the upper pipe of the first cross.
• A ball valve with a fitting for connecting an additional receiver is screwed to the lower end.
• A second cross is attached to the left pipe.
• A pressure gauge is attached to the upper end of the second cross.
• A ball valve is inserted into the lower pipe to supply air from the compressor.
• An oxygen reducer is connected to the left pipe through a ball valve.
• A hose is connected to the reducer to connect the consumer.

Do not use the cutting tool until complete removal remaining gas from the container. Flame sparks are generated when the cutting tool is in use. A spark entering a vessel may cause an explosion.

Advice: To remove residual gas, the cylinder is filled with water and kept filled for several days. After a long soak, the water is drained. The filling and emptying procedure is repeated several times.

Anti-corrosion detergents are used to remove rust and dirt.

Single-chamber and dual-chamber receiver device

The compressor receiver consists of two main elements:

• container (cylinder);
• gearbox

The reducer is designed to regulate the pressure when the working mixture leaves the vessel.

There are two types of gearboxes:

• single-chamber;
• two-chamber.

Single chamber gearboxes

Such gearboxes have one low-pressure chamber. The gas from the cylinder first enters the high pressure chamber. There is a shut-off valve between the chambers. Under high load the valve is in the closed position. The valve is opened using a special screw on the gearbox.

Gas from the high-load compartment enters the low-pressure chamber. The working mixture is supplied to consumers.

To control the pressure in both chambers there are pressure gauges. A safety valve is used to regulate the load. When the load increases above the set norm, the valve automatically opens and gas flows out.

The simplicity of the device allows the use of single-chamber gearboxes for the production of standard compressors.

Double chamber gearboxes

Receivers with such reducers have two low-pressure chambers. They are located sequentially, one after another. The workload reduction process is smoother and more precise.

Double-chamber gearboxes are capable of operating at low temperatures. They differ in the complexity of their design. Used in industrial installations with high compressor power.

Two-chamber gearbox design

Device with pressure sensor

Pressure sensors are used to continuously monitor the operation of the compressor unit. They perform the following functions:

• monitoring the level of gas or liquid in the receiver;
• measuring the flow rate of the working mixture.

There are two types of pressure sensors:

• sensor for measuring absolute value;
• sensor for measuring excess value.

The main measuring element of the sensor is a ceramic membrane. It consists of a ceramic cell. The ceramic cell is a capacitor. The capacitor consists of a ceramic substrate and a conductive membrane coating.

Under the influence of the working mixture, the membrane is deformed and the value of the electrical capacitance changes. The absolute pressure cell is a closed system. It is used to measure pressure relative to vacuum.

There is a hole in the ceramic substrate of the gauge pressure sensor for air access. The measurement is carried out relative to the ambient pressure force.

Ease of manufacture and a wide selection of available materials allow you to use a homemade receiver in the household. When operating the compressor unit, it is necessary to comply with the rules for operating pressure vessels. Compliance with these rules will ensure safe operation of the installation for many years.

Capable of operating only from receivers. These devices are responsible for the pressure inside the system. Many modifications are made with relays that differ in clamping force. It should also be noted that receivers can be equipped with sensors. Filters are most often used with clamps. If necessary, you can make a receiver for the compressor yourself. However, it is important to consider the type and capacity of the compressor unit.

40 liter devices

Making a receiver for 40 liters is quite simple. First of all, a camera for the device is prepared. Typically, stainless steel sheet is used. Experts say that the lid should be welded last. It should also be noted that there are two-chamber modifications. The easiest way is to use a low conductivity relay. Homemade modifications, as a rule, are not equipped with sensors. Gearboxes for devices are selected of the chain type. In this case, valves with a tee are used to purge air.

60 liter modifications

An additional receiver for a 60-liter compressor can be made with two chambers. Experts say that the sheet of metal should be at least 1.3 mm thick. Tees are most often installed next to the relay. Receivers of this type must be equipped with two filters. In this case, the gearbox should be installed with an adapter. 60 liter modifications are great for low power compressors. The maximum pressure indicator for systems is 6 bar. It is also important to note that only the duct valve should be used during assembly.

80 liter device

Air receivers for an 80-liter compressor can be made with two relays. Experts say that filters are selected with a large diameter. The outlet pipe of the receiver should be in the upper part. Intermediate filters are mounted via an adapter. It should also be noted that modifications with stops located inside the chamber are considered common. The pressure parameter for receivers of this type is approximately 10 bar. They use wired relays. The maximum compression force is 3 N. Tees for modifications are selected with a diameter of 2.2 cm. It should also be noted that sensors are often installed in devices to monitor pressure levels.

Single Valve Models

How to make a receiver for a compressor with one valve? Housing in in this case used for 30 liters. You can also consider more compact modifications. To assemble the receiver, the camera is first prepared. The hole for the gearbox is welded to a small diameter. Experts recommend using only wired relays with a tee. The diameter of the outlet pipe for a 30-liter modification should not exceed 2 cm. The check valve is mounted at the base of the filter. It should also be noted that modifications with two outputs are considered common. They are great for 10 kW compressors. In this case, the pressure in the system can be maintained at 5 bar.

Two valve device

The receiver for a compressor with two valves is assembled with a capacity of 40 liters or more. On average, the pressure for models of this type is 4 bar. The devices differ primarily in relay conductivity. Their maximum clamping force is 7 N. Many modifications are made with a contact gearbox with two outputs. If you are assembling a simple modification, then it is more advisable to use a tee without a sensor. It is also important to note that a check valve should always be installed behind the filter. Experts say that the outlet pipe is welded last.

Single chamber devices

The single-chamber modification is suitable for compressor units of different capacities. Devices of this type are actively used in large factories. Modern models are distinguished by their high pressure parameters. They use a safety valve and have a protected gearbox. To assemble a single-chamber receiver yourself, it is recommended to make a container for it. The relay is used with a conductivity of 1.2 microns. In this case, the downforce must be a maximum of 12 N.

Check valves are installed behind the filter. The gearbox should be located in the rear part of the tank. The optimal diameter of the outlet pipe is 2.2 cm. However, it is important to consider the volume of the chamber. If you assemble a 40-liter device, then the intermediate filter is installed behind the relay. It should also be noted that before using the equipment, the chamber must be checked for sealing.

Two-chamber modifications

A two-chamber homemade compressor receiver is made with a 60-liter tank. Some devices are made with a sensor. For self-assembly The model will need to make a camera and also make a hole for the pipe. The relay is usually used as a wired type. It is more advisable to use adapters with wraps. Experts say that the receiver must withstand high pressure. The optimal diameter of the outlet pipe is 2.2 cm. Valves for devices are selected from steel or aluminum alloy.

Using gearboxes with interlocks

It is difficult to assemble a receiver for a compressor with blockers. First of all, it is important to note that the models must have a high permissible pressure parameter. Device filters only fit on pads. It should also be noted that the relay must be installed in front of the gearbox. Experts say that receivers of this type are produced with small tees. Some modifications are assembled with carriers. Sensors are used to normalize the pressure inside the chamber. Check valves are installed with baffles. They are able to pass air only in one direction.

Devices with pressure sensors

The compressor receiver is produced with cylinders of different capacities. Some devices are suitable for powerful compressor installations. However, in this case, much depends on the diameter of the pipe. If we consider models with one outlet, then their permissible pressure indicator is on average 5 bar. In this case, the downforce can reach a maximum of 12 N.

Check valves can be installed with or without pads. Gearboxes can be found in different conductivities. Tees on receivers are installed with a diameter of 2.4 cm. If we consider simple modifications, then they use only one filter. The permissible pressure indicator for receivers of this type is about 2 bar. They are suitable for compressors with a total power of 8 kW and above.

The compressor is a rather complex engineering structure, which includes many components and assemblies, including such as a receiver. This is the name of the vessel in which the compressed gas produced during the operation of the compressor is stored.

Why do you need a receiver in a compressor?

The receiver included in the supercharger provides a solution to several complex problems, in particular:

1. Guarantees stable pressure working environment transported to consumers.
2. Provides gas transportation at a time when the compressor begins to operate intermittently, or an additional consumer is connected to the air supply system.
3. Cleaning the compressed air mixture from accumulated moisture.
4. The accumulation of gas in this container leads to a decrease in vibrations in the compressor. This in turn reduces the level of force loads affecting the foundation.
5. To perform work that involves production large quantity gas is standard, the installed vessel may not be enough, then instead of purchasing and installing a stronger compressor, an additional capacity is installed on the old compressor.
6. The receiver ensures that the compressor is turned on at a certain frequency, and this leads to a decrease in electrical energy consumption.

In essence, a compressor receiver is a container of a certain size. For mobile compressors, containers with a volume of 50 to 100 liters are used. For stationary units, receivers with a volume of up to 1000 liters are used.

Filters are installed on them, which purify the gas from moisture; in addition, the design of the receiver includes condensate drains and shut-off valves. It is used to connect the compressor to consumers.

For the manufacture of receivers, corrosion-resistant steels 10HSND or 16GA2F are used, meanwhile, in rare cases, polymers or high-strength elastomers are used for low-power units.

Manufacturers produce two types of containers - horizontal and vertical. The first version is used for mobile type compressors, the second version is used for stationary compressors.

Each of the versions has its own advantages and disadvantages. For example, in a vertical design it is easier to drain water, while horizontal ones have more compact dimensions and they require shorter piping lengths.

How to choose the optimal receiver parameters

Like any technical product, the receiver has a number of technical parameters. Among them are:

1. Volume, l.
2. Humidity.
3. Operating parameters, that is, limit values ​​of humidity and temperature.
4. Characteristics of the installation location of the compressor unit. It must be installed away from sources of heat, fire and explosive substances. The presence of foreign particles in the air is undesirable, for example, in procurement areas.

Safety rules state that it is unacceptable to use receivers that have not passed the appropriate test, the surface of which has mechanical damage in the form of cracks and traces of corrosion.

The selection of a receiver is carried out on the basis of a fairly simple calculation:

1. The required flow rate of the air mixture, the duration of the flow rate, and the maximum operating pressure are determined.
2. Using special calculation tables, they exist both in paper form and as Internet applications. For example, with a productivity of 0.1 cubic meters per minute, a maximum load duration of 5 minutes and within a pressure range of 3/4 (min/max), the volume of the receiver will be about 500 liters.

This method of calculation is focused on the time required to completely empty the container.

There is another technique based on the ratio of the volume of the vessel and the power of the air compressor. In practice, the following ratios are used:

1. Power 5 kW, volume max – 100 l.
2. Power 10 kW, volume max – 300 l.
3. Power 20 kW, volume max - 550 l.

There are also experimental dependencies, for example, the volume of the receiver cannot be less than the amount of air that the compressor can produce for 8 seconds of operation. For example, the flow rate is 400 liters per minute, respectively, the volume of the poppy must be at least 53 liters.

Do-it-yourself additional receiver for a compressor

Some work performed in a home workshop or garage requires compressed air. And a situation may arise when a household compressor cannot cope with the task. In this case, the situation can be resolved by installing an auxiliary receiver on the existing unit. This device can either be purchased at a specialized store, for example, car spare parts. There you can buy a receiver for the KAMAZ pneumatic system, or make it yourself.

Most of the receivers offered are made for a specific model and are distinguished by a high price. Depending on the planned size of the container for self-made, you can use either a propane tank or a fire extinguisher body.

The procedure for making a homemade receiver

The sequence of manufacturing an additional vessel looks approximately as follows.

1. Cleaning an old vessel from gas residues. To do this, you will need to clean it of gas residues. The inlet valve is removed, while using an electric tool, for example, an angle grinder, gas residues may remain in the housing.
2. The vessel is filled with water and allowed to stand for 24 hours. Then it is drained and the internal cavity is cleaned of dirt.
3. After this, splitters under the sleeves are welded into the cylinder, but it is also permissible to install threaded fittings; to increase the tightness when installing plugs, it is necessary to install sealing gaskets.
4. A homemade receiver must be painted with weather-resistant paint.
5. A condensate drain is installed in the assembled and painted maneuver - its place is at the lowest point of the tank, and a pressure gauge is installed in the upper part. The brand of condensate drain must be consistent with the compressor capacity and thread sizes. The cost of such a device ranges from 2500 to 3000 rubles.

When operating a condensate trap, we must not forget that its installation on an auxiliary gas storage tank is mandatory. Before switching on the operating load, it is necessary to check the condition of the electric drive to ensure that it can be operated with an auxiliary gas container.

To do this check, you need to turn on the compressor and use a flow meter to check the pressure surge during long-term operation (about 20 minutes).

If the minimum pressure corresponds to the declared characteristics of the supercharger, then operation of the assembled structure is quite acceptable. If the pressure drop is below the permissible level, then the use of this equipment is questionable and it is undesirable to use it.

The use of an air receiver serves several key purposes

Using a compressed air storage vessel allows the compressed air to be stored in the air supply system. Improve the quality of the supplied air mixture; when passing through this container, the air flow is dried, foreign particles settle down and do not enter the pneumatic line. In general, the use of a receiver leads to an extension of the operating life of the compressor.

Advantages of horizontal receivers

The obvious advantages of horizontal containers include stability. This type of construction provides high resistance to vibration and other external influences. On the other hand, a horizontal layout requires more space to accommodate the compressor.

Advantages of vertical receivers

The use of vertical containers for storing compressed air makes it easier to install the device in a specific location and leads to space savings. This is especially true in the case of constructing a series or parallel connection of containers.

Manufacturers present to consumers a wide range of model range vertical air storage devices

In order to create an additional reserve of a certain volume in the compressed air supply system, you may need to buy an additional receiver and install it in the existing pneumatic line.

Installing such equipment will help solve several production problems at once:

The supply of air that creates will allow you to avoid sudden surges and drops in operating pressure in the system;
- the compressed medium will be distributed more evenly;
- the operation of pneumatic consumer elements will become more stable;
- the number of compressor starts will be reduced, and it will operate in a more gentle mode;
- installation of an additional receiver will ensure the separation of some of the oil and moisture from the working line, which will reduce the load on the air treatment system.

As a rule, for piston and screw units of small and medium performance, a volume of 500 to . Such models are quite sufficient in most cases, and in addition, such equipment does not require registration with inspection authorities. Large capacity installations, including blowers, may require an additional receiver with a volume of 10, 20, 30, 50 cubic meters or more, which are more often referred to as.

In our catalog you will find additional compressor receivers of various sizes, designed for a wide range of pressures. When choosing equipment, be sure to keep in mind that the larger the volume of the receiver you install, the less often the compressor will start working, but at the same time its operating cycle to achieve the upper pressure threshold will be longer.

Additional receiver for compressor - price

The cost of an additional receiver depends on its working volume and maximum excess pressure. In addition, the cost can be influenced by such technical factors as: the material that was used to produce the receiver, its external and internal coating, the presence and quantity of auxiliary fittings. Often, the popularity of the manufacturer can also affect the price, so we recommend that you study this issue very carefully.

To increase the efficiency of working with compressed air, many compressor units use receivers - containers for storing air under pressure. Based on the intensity and volume of work, containers of 50, 100 liters, sometimes more, can be used. In this article we will look at how to make an additional receiver for a compressor with your own hands, why it is needed in general, and what characteristics should be taken into account when assembling it.

What is the receiver for?

The receiver is required for the compressor to perform the following functions:

• The receiver accumulates compressed air, which helps reduce vibrations in the system. This in turn reduces the load on the base and reduces the noise level from a stationary installation;
• Stabilizes the air pressure supplied directly to the work area. In this case, differences in pressure are inevitable, since the operation of any compressor involves the injection and suction phase of air;
• Air purification from condensate. IN otherwise due to increased pressure, air humidity would also increase, which would lead to corrosion of the steel surface of the compressor;
• Provides compressed air supply when connecting an additional consumer, as well as during interruptions in the operation of the compressor.

To obtain large volumes of compressed air, a standard receiver may not be enough. For example, for sandblasting large surfaces, instead of a more powerful compressor, purchase additional receiver.

In addition, the additional receiver makes it possible to use the compressor less often, thus reducing energy consumption!

From a design point of view, the receiver is a sealed tank in most cases with a capacity of 50-100 liters. In the case of stationary units, containers up to 500-1000 liters can be used. The device is equipped with condensate drains, air filters and shut-off valves for connection to the working device and the main unit that consumes compressed air, be it a spray gun, nozzle, etc.

The container for compressed air is made of steel - usually from 16GA2F or 10HSND steels, which are resistant to corrosion. However, in the case of low-power compressors, plastic receivers, and even those made of high-strength rubber, can be used.

Paired with the installation, the receivers can be equipped both vertically and horizontally. The first is in most cases used in stationary units, the second - in mobile ones. Each type offers its own pros and cons. For example, horizontal receivers require a shorter pipeline, since they are more compact, but vertical ones are much easier to drain condensate.

Deciding on the parameters

In addition to capacity, the compressor receiver can be characterized by the following parameters:

1. Requirements for the location (within air contaminated with mechanical particles, for example, near circular saws, away from explosive, flammable materials and heat sources).
2. Working conditions (relative air humidity should not be more than 75-80 percent, temperature around 15-40 degrees).
3. Maximum air humidity levels .

According to the requirements of PB 03-576-03, it is prohibited to use receivers that have defects on the surface, such as corrosion, dents and cracks, as well as those that have not been tested for the functionality of the container walls.

The characteristics of the receiver for the compressor are selected as follows. The first step is to determine the maximum and minimum pressure values, the duration of operation and the required compressed air consumption. The next step is to find the required data using a table with online calculations, which can be easily found on the Internet upon request. For example, in the case of a maximum/minimum pressure drop of 4/3 atm, a maximum load duration of 5 minutes and an air flow rate of 0.1 m 3 /min, the optimal volume of the receiver tank will be considered 500 liters.

This method focuses on the time during which the receiver will be completely empty. However, there is a simpler tabular method that allows you to correlate the power consumption of the compressor with the volume of the receiver. Among them, it is worth highlighting the most commonly used ratios:

• Up to 550 liters for compressors up to 20 kW;
• Up to 300 liters for 10 kW models;
• And up to 100 liters for 5 kW products.

If necessary, intermediate values ​​can be calculated by interpolation. There are also experimental dependencies. According to one of them, the capacity of the receiver tank should not be less than the compressor performance during 8 seconds of continuous operation. In this case, the volume of the tank at an air flow rate of 400 l/min can be calculated as follows:

V = (400*8)/60=53.33 l

Rounding up we get 54 liters.

Do-it-yourself additional receiver for a compressor

Some work in a workshop or at home may require increased consumption of compressed air, which household compressors are not capable of providing. One of possible solutions will place an additional receiver for the compressor. The cost of such a device, based on volume, will be 12-15 thousand rubles if you buy it in a store, but nothing prevents you from saving money and making the receiver yourself. An additional advantage in favor of the second solution is that most of the models offered in the store are designed for standard compressors, which is why their price is so high!

The connection of the additional receiver is usually carried out in series with the main one, and therefore, depending on the required volume, a regular fire extinguisher body or a cylinder left over from liquefied gas may be suitable for operation.

As in the case with, making a homemade receiver begins with thoroughly cleaning the cylinder from gas residues. For this purpose, the first step is to remove the inlet valve. It is important to note that removing the valve cannot be used with power tools, as there may be gas residues inside!

After this, the bottle is filled with water for a day. Next, threaded plugs with gaskets are screwed into the container or tubular splitters for hoses are welded. At the end, the balloon should be processed weatherproof paint!

You can install a condensate drain at the bottom of the container; it would also be useful to have a pressure gauge or pressure switch on the receiver. In the case of a condensate drain, its size should be selected based on the dimensions of the connecting thread, operating pressure and compressor performance. The average cost of condensate traps is around 2.5-3 thousand rubles.

Below in the photo you can see the finished additional receiver for the compressor, placed on top of a tripod welded from a steel rod.

When working with a homemade device, you should consider the following points:

• As the pressure decreases, the operating time will have to be reduced from the usual 75-80 percent to 50-60. For lower values, it is not practical to use a self-assembled element;
• Before putting a full load on the compressor electric motor, you should first check the possibility of its operation in conjunction with an additional receiver! For this purpose, the compressor drive is started at idle, after which, during prolonged operation (more than 20 minutes), the pressure difference is measured with a flow meter. In this case, the additional receiver is suitable for operation if the pressure during testing does not fall below the minimum value;
• In the case of an additional tank, the installation of a condensate drain is considered mandatory.

Well, now you know what a receiver is for, what it is, what characteristics it has, and also how to install an additional cylinder to the main tank. We hope the tips presented will be useful to you. Good luck!
