Compressor manufacturing process:
Step one. Install on the tank wheels
We install on the tank of the wheel so that this sweature car can be transported. To do this, we install reliable steel clamps onto the tank and we are tightened by their bolts with nuts. It is to these clamps then we will fix everything necessary equipment.
We also need to fight the leg in the front of the car, it is made from a piece of pipe to which the Pyhat from Sheet Steel is welded.
Step second. Making frame for equipment
Compressor, as well as the engine will be installed on top of the receiver, they will be attached to the clamps. We make the frame from the corner, as well as sheet steel. Under the compressor drills holes and cut the thread, it will be static with the help of screws to the frame.
We weld the pieces of steel plates to the frame and then we install the frame from above the receiver. You can fight the frame and the handle to be, for which you take the compressor, the author welded it from the profile pipe.
Step Three. Adapter
In the cylinder there is a hole of a large diameter, you need to make an adapter, the author made it from sheet steel. We apply a piece of paper to the hole and pencil we are looking for where to drill holes. Well, then the case of the technology, cutting off the workpiece, drill holes and screw the pipe. It is very important that the weld seam is strong and hermetic.
With the help of the submitted means and the standard set of household tools, any householder can collect a homemade air compressor from the refrigerator. The scope of such an apparatus is quite wide and justifies the costs of forces and means on its manufacture:
Homemade air compressor from the refrigerator
The range of possibilities, power, durability and reliability of the self-made system of compressed air generation collected on the basis of the compressor from the old refrigerator depends on the correct design and installation of its elements.
Compressor from the old refrigerator
The assembly of the functional and reliable apparatus begins with the choice of its main part - compressor. It is available in any household refrigerator, performs the function of the pump for pumping the refrigerant and is a single block in a hermetic metal shell, with the outside of which the relay is attached to run it. To solve the problem, any similar motor in good condition will suit. Further selection and configuration of all additional structural elements is determined by the form and characteristics of a particular device.
If there is no old and unnecessary refrigerator at hand, it is always possible to purchase a dismantled unit on the used tools and spare parts market. There you can buy a workable option for 100-150 rubles.
Dismantling of the compressor with your own hands from the refrigerator
Removing the device from the refrigerator can be made by conventional wrench and scuffers. Tubes feed and exit air is better to snack, and not to cut off, so as not to clog the mechanics of the device. The regular startup relay is also dismantled.
The possibilities and characteristics of the compressor selected as the basis for the future compressed air supply mechanism should be taken into account. There are the following options:
Both options are suitable for work, but their features should be taken into account. Linear devices are designed for constant speed. Therefore, they are better suited to create a compressor apparatus. Converter variants are calculated on the variable speed, which should decrease depending on the signal from the temperature sensor.
Refrigerator compressor performance
In order to check the performance of the block, it should be turned it first using an electronic resistance meter, and then connect to the network:
To check the connection, the voltage is fed to a working and phase contact, after which a short-term closure of the working and start contact is made. The device must create a stable voice timbre when turned on, and airflow should go from the output tube.
Preparation of equipment for homemade compressor station
When developing a compressor station and list additional equipment It should be considered the planned scope. The greater the receiver and pressure in it, the wider there will be homemade. The standard scheme includes the following parts and mechanisms:
An old compressor from the refrigerator can be cheap to buy on the used tool market
Most parts for the compressor station are easiest to buy in the plumbing store. There are specialized sites where all items without exception can be ordered in several clicks. Much cheaper needed equipment can be purchased on the market for used tools. It is permissible to use cheap fuel filters, but with the help of conventional fitting and a metal sponge for washing dishes, you can quickly make a more reliable filter for coarse air purification from the oil, which is installed on the outlet tube of the engine unit.
Homemade welded receivers
Callers for homemade compressor equipment on sale not to find. For this purpose, cylinders of various purposes and tank are reworked for this purpose:
ATTENTION: When using self-made corps under the receiver, it is necessary to take into account the degree of risk and explosion of such a device.
The simplest option is steel pipe Medium diameter with hermetic plugs. In the receiver case must be at least 3 bandwidths:
When using steel cylinders, the input and output tubes are welded with welding. The housing must withstand more than 10 atmospheres.
When connecting the compressor unit, you can leave the same scheme as it was provided initially through the start relay. You can attach the pressure sensor wires to this relay, which will interrupt the chain after reaching the calculated pressure parameters in the receiver. Additional amenities is the equipment of the entire system with a push-button switch and LED indicator of work. Before connecting in the block, it can be changed oil. Old oil is designed to work with Freon. Special compressor oil for work in air Protects the electric motor from overheating and premature failure.
Installation of the fuel filter on the inlet tube of the compressor from the refrigerator for cleaning the air flow
For landing on the inlet tube air filter, most simple option Which is a plastic fuel filter, you can use both soft rubber hose and metal corner fitting with a threaded connection. The connecting soft tube, stretched on the plastic tip of the filter and the copper inlet, is easiest to blame the metal protracted clamp.
The air jet coming from the block contains a significant amount of oil, which can be filtered using a homemade clipper. In its case, a drainage hole with a crane should be provided through which it can be cleaned. Between the oil cutter and compressor block It is allowed to install a cooling coil made of metal tube.
Preparation for the assembly of a highway with control and measuring equipment for the compressor station
All control and measuring devices are easiest to post on one highway. This will require conventional metal tees from the plumbing store. On a single platform, a system shutdown sensor is placed when the operating pressure is reached, a pressure gauge, a device for cleaning air from condensate accumulating in the receiver and a safety valve, with which you can quickly reset the excess air from the cylinder. At the outlet of the highway, you can arrange a control ball valve. The main unit is connected to a cumulative cylinder or through its standard inlet, or with the help of improvised entrance on its body.
If the diameters of the installation instrumentation do not correspond to the size of the available fitting, then in this case all devices can be installed using the plugs in which the holes are drilled by the required value and the thread with the corresponding step is cut. Threaded compounds are compacted using FMU tape.
Oxygen hoses with thick walls are one of the most affordable materials for connecting all parts of the compressor unit. But it should be borne in mind that the air jet at exit from the engine compartment will contain a large amount of oil that destroys the rubber. For this reason, it is preferable to use metal (copper, or steel) tubes.
Maintenance of the homemade compressor station should be carried out taking into account the features of its configuration. It should periodically check the performance and tightness of all nodes. Violation of the tightness of the locking devices is easy to identify if the pressure measurement device is installed, which will immediately show it a quick loss. The performance of the pressure sensor is easy to control using a pressure gauge, the readings of which can be fixed at the time of the standard shutdown of the system after filling the air tank. It should also regularly drain condensate and oil from filters and cylinders.
Recently, compressors have gained popularity among lovers to make. They are made on the basis of almost any engines, calculating the capacity of the basic unit depending on the number of consumers. For domestic workshops, self-made compressor settings made by their own hands are in demand.
Compressors from refrigerators often remain workable after breakdown or obsolescence of the refrigerator itself. They are low, but it is unpretentious in work. And many masters of them do quite decent homemade installations. Let us see how it can be done with your own hands.
In some cases, it is not possible to do without a different work on the house without an air compressor. If there are sufficient skills, as well as some source nodes and parts, such an aggregate can be made independently.
First of all, he will need the owners of individual vehicles. Painting the car, cleaning the cabin and the engine from dirt and dust, bringing pressure in the tires to the desired value - only a small list of operations that the homemade compressor can perform. The scope of the assembly of the unit will increase dramatically if the farm will appear pneumatic tools. For example, in the country, their use in many situations turns out to be more profitable than electric: there is no binding to a stationary power line, and designs based on the use of pneumatics, often turn out to be more reliable.
Before making the manufacture of a home air compressor, you should create an initial technical task in which to clarify the following requirements:
To fulfill most housework, it is enough 4 ... 6 AT, however, it should be noted that with long-term use of the compressor, its moving parts are heated, which is why this feature Over time, it may fall at 20 ... 30%. Performance is determined only technical characteristics pneumatic tools. Minimized consumption is usually for drills, wrench and dowel mounting pistols (up to 100 ... 120 l / min). At the same time, for the tool of shock action or grinding machines, consumption will be required to 350 ... 400 l / min. When performing outdoor work (in particular, painting), higher performance values \u200b\u200bmay be required, so it is necessary to provide a margin for this parameter at 20 ... 30%. The same approach is also needed to estimate the power consumed by the unit.
Any compressor needs a receiver - a cumulative capacity that maintains air pressure in the limits required for stable operation. With an increase in the capacity of the capacity, the functionality of the air compressor increases, although dimensions Installation will increase. Nevertheless, the volume cannot be less than 10 liters. It should be borne in mind that for the purposes of painting the length of pipelines (and, consequently, loss) will increase.
How to make a compressor, and in what sequence to produce work?
To make a compressor with your own hands, you will need:
How to make a compressor? The following sequence of preparation and assembly of elements is recommended: input intake hose with nozzle → Pre-cleaning filter → Final cleaning filter → Hard front inlet to compressor → Compressor → Pipeline for replacing oil → Output Pipeline on receiver → Tee → Receiver → RD Relay with Emergency Safety Valve → Tee with pressure gauge → Controller with valve → Combined output filter → Hose with self-paging pneumatic socket.
At the initial stage, a compressor from the refrigerator has to be prepared. It is cleaned from the inside of dirt and impurities, subjected to painting, and drain the oil (more than it is likely that it was not necessary for all the time of operation; however, for the refrigerator and the need for special needs). The compressor already has a starting relay configured on its parameters, and it is not recommended to change it. The sealed hole at the bottom of the housing is intended for draining oil. This hole is neatly revealed (particles of chips should not get inside) after which, with the help of a syringe, the old oil is removed, and the oily cavity is filled (any synthetic or semi-synthetic oil is suitable, the characteristics of which are almost constant). Oils must be poured at 30 ... 40% more, given the natural decline, for example, with continuous painting of significant surfaces.
The next stage is the preparation of the aircraft. The internal volume of the fire extinguisher body must be carefully cleaned using the rust converter. After that, at the bottom of the case, a threaded hole is obtained, which dries a plug: it is necessary for periodic drain condensate. The tee is attached to the outlet. Possible problem - Missing the thread - is solved by reminding it. The conversion valve is attached to the opposite ends of the tee (its parameters are selected taking into account the needs) and the second tee, also equipped with a pressure gauge. Cumulative capacity subject to mandatory painting.
Ends installation by attaching to the outlet of the second tee filter-oil separator. This tee should be equipped with a manual valve and a renal control manometer. Connection to the last output hose The assembly process will be completed.
It remains only to install all collected components on the frame. It is better for these purposes to use aluminum corners or a tolstolic phaneer. It is recommended to set the compressor from above: so facilitated the subsequent use of the unit. To avoid excess noise and vibrations, all nodes must be toughly fixed on the frame, with the exception of the compressor itself: it must allow some fluctuations. To do this, it is better not to dismantle the fasteners remaining on it, or, if they are absence, provide for the installation of the compressor on spring compensators.
The main check of the self-made compressor is to determine the possibility of effective pressure regulation, which is created in collected system. The easiest way to do this with a test painting of any surface. At the same time, the following is sequentially:
The work collected by their own arregates will be long and reliable, if it periodically holds it regulatory service. It comes down to replacing the input filters, the periodic purge of all air lines, as well as the oil change in the compressor.
It is not necessary to buy a compressor for painting works or packed wheels - you can make it with your own hands from the used parts and knots taken from the old technology. We will tell you about the designs that are collected from the primary materials.
In order to make a compressor from parts and used components, you need to prepare well: examine the scheme, find in the farm or buy some details. Consider several possible options For self-constructing air compressor.
This unit works almost silently. Consider a scheme of a future design and make a list of necessary nodes and parts.
1 - tube for pouring oil; 2 - launch relay; 3 - compressor; four - copper tubes; 5 - hoses; 6 - diesel filter; 7 - gasoline filter; 8 - air inlet; 9 - pressure relay; 10 - Cross; 11 - Safety valve; 12 - tee; 13 - Receiver from the fire extinguisher; 14 - pressure reducer with pressure gauge; 15 - moisture meadow; 16 - Pneummatore
The main elements are taken: a motor-compressor from the refrigerator (better than the production of the USSR) and a fire extinguisher's balloon that will be used as a receiver. If there is no available, then the compressor from the broken refrigerator can be searched in workshops on repair or in metal reception locations. The fire extinguisher can be purchased in the secondary market or attract familiar to finding, at work, which can be written off OKHA, OVP, OU by 10 liters. The body of the fire extinguisher must be safely emptied.
In addition, you will need:
Another viable receiver turned out of a car without a carless wheel. Extremely budget, although not too productive model.
