And so the essence of the question is that there is a hammered compressor so7b, but due to its constructive simplicity and rather good performance, I think that it makes sense to do it. If anyone has used such a unit, then I would like to hear reviews about it, whether it is worth using it as a painting unit or not. I also wanted to find out what to do if the liner, or rather the babite filling, is worn out, are there any repair liners, or do you have to completely change the connecting rod? I would also like to know what to pour into the crankcase? There is not a lot of information on this topic .. Honestly, if it is not planned to carry out painting work on an industrial scale, this compressor is fucking unnecessary. Painfully, he is ugly and heavy. Relevant when you need a very high air flow and at minimal cost. You can get spare parts for it, they are cheap. As a last resort, order online. Oil - KS-19. Thanks, at least something! On an industrial scale, no, of course, painting is possible, and I want to make an anticorrosive underside of the car. Video (click to play). Special thanks to the oil brand! And not vkurse what to do with the connecting rod, the babit is almost all melted .. The connecting rod is in the trash? In principle, any compressor oil can be poured, preferably not the most expensive (passport oil consumption - 30 grams per hour), and KS-19 according to the passport it is supposed to. Most likely, it will be easier to change the entire connecting rod, it costs about 500 rubles. I also tend to this, but I'm afraid that it will not be successful in 500r, according to the price list in St. Petersburg, the connecting rod for the compressor costs around 1500 - 1900r somehow unjustifiably expensive IMHO Previously, spare parts for it cost a penny, now - alas! It may turn out to be an economy. it is more expedient to take its motor as a basis, to buy a NORMAL MODERN (and small. at the same time) compressor. the head (here - who will like something, or maybe it will break off "on occasion"), "make them related" with a belt on a suitable channel, and throw out the rest. For this unit is extremely inconvenient (heavy and cumbersome). Anyway - the receiver is normal with moisture separation and precise pressure control, a start relay (preferably with a decompressor to start), or even an “oil-additive” (I don’t remember how this crap, adding oil to the air for lubricating pneumatic tool, scientifically called) - NECESSARY. For at the construction site (where he always had a place, if you think about it) - all these nishtyaki - clearly "from the evil one." Repeatedly came across broken pistons and valve plates (with remnants of plates). Works monstrously loud, vibrations, etc. "discomfort" - beyond any reasonable limits. These valves are unreliable. Spare parts are very expensive. Dealing with it will protect. and regul. valves I did not succeed to the end (the first for some reason had a frenzied hysteresis loop and if they worked, then they dumped too much, the second - from time to time changed the mouth level). They wanted accuracy - they installed large (by the diameter of the scale) pressure gauges on adapters. So they generally "seem to" the dollar rate on the Tokyo Stock Exchange - the arrow jumps SO that you understand the hell, you had to return the regular ones (and you can see the hell from afar). As noted above, only a decent air outlet makes this venture at least somehow justified, but the pressure at the same time is still not enough for sand. Paint brushes and so on. Nice little things - yes, but maybe it's worth looking at something else more decently? Shl. And although my soul does not lie for China, there are some of them. Apparatus in general from 4 sput go. ZZY. An idea about an upgrade: the power of the old 3.5 kW - the motor is quite enough even for a modern 3-cylinder head, we leave only the wheel from the healthy flywheel-propeller (it's easier to put a separate motor-fan on the side for cooling and not be fooled) and the casing. We mount it on a suitable channel, without forgetting about the wheels and "transport" handles. The structure is taken out into the street, the receiver with ave. Pneumatic crap - in the garage against the wall. If you need a "highly compact" arrangement - a vertical scheme in a cube frame, a motor on the bottom of the swinging frame (to adjust the tension), a head with a flywheel - on top, and a fan on the side. And yet - air. the filter there just sucks. Take the time to familiarize yourself with the design 🙂 🙁 I heard - they were putting a "Zaporizhzhya" pan on the side. You can try something simpler, of course (for example, a VAZ “classic” “frying pan” with a dry replaceable filter ring inside), but only there, on the head, the air supply is EXTREMELY inconvenient and is designed for a standard cast (made of alloy) manifold.

In my case, this liner is gobbled up, or melted, well, in general, it’s not the point, the point is that apparently you will have to change the connecting rod, as well as the inlet valve that is on the side of the cylinder, since the frame holding the petal, apparently due to vibration, has weakened and deviated, in as a result, it was flattened by a piston .. There is no other head, perhaps the Zilov compressor, but it also needs to be modified to run from the electric motor .. ZIL-ovsky can be started from a regular motor (1-phase), and then - buzzing! In our 3-phase garages, an unprecedented luxury. Only WHY it is needed - unspecified. CO-7 is a typical "general use" design, it is easy to pump up tires with it. Whether on a motorcycle, even on a jeep. Blowing is also not a problem. Pour Movil (this is already auto). Paint the fence with a HOLIDAY (not to be confused with AUTO) spray gun. And in the garage, the tasks are different: painting is one thing, sand glass is another. There is also a specific specificity in the form of a pneumatic tool. And then the costly part for the unit itself is already lost against the background of the connections-transitions-nozzles-spray guns (and mooring to them), oil separators and oil “additives”, manometers-thermometers (viscometers), again, the receiver needs a normal ... One travel spray gun (without spare parts) costs like a whole compressor. Plus the noise, dustiness and so on. The discomfort from this monster is an oil painting.

Brief repair instructions Repair of compressor installations is subdivided into: current (T) - carried out every 1500 hours; capital (K) - carried out after 7500 hours. During routine repairs, the compressor is partially disassembled, malfunctions in units and parts that arise during operation are eliminated, and individual parts are replaced with new ones from the set of spare parts. For current repairs, you should: clean the compressor valves from carbon deposits. To do this, you need to disassemble the valve plate; Carefully clean each valve plate and their seats of carbon deposits and rinse with gasoline, and then dry them thoroughly. Lubricate the plates and sealing surfaces of the valve plate with a thin layer of compressor oil, and then collect it. If the working surface is damaged, replace the valve plates with new ones; clean the bottom of the pistons, the discharge cavity of the compressor head and the discharge pipe from carbon deposits. Rinse cleaned surfaces with gasoline and dry them thoroughly; clean the discharge line from carbon deposits. To do this, remove the pipeline, rinse it with 5% caustic soda solution until it is completely softened and remove carbon deposits, rinse with water and dry. Flush the receiver and oil-moisture separator in the same way; clean and rinse the cooling fins of the cylinder block and head. During the overhaul, the compressor is completely disassembled, all initial landings and interfaces are restored in accordance with the requirements of the technical specifications for the overhaul of SO-7B UK. If a malfunction is detected, the compressor must be stopped. The compressor can only be started up after the fault has been eliminated.

And at this moment, as luck would have it, there is a need for it. Do not be afraid, after studying theoretical information, repairing a compressor with your own hands will not seem like something unattainable. The main purpose of air compressor units is to create a continuous, uniform jet of compressed air. The dense gas stream is then driven by various pneumatic tools.These can be airbrushes, tire inflation guns, wrenches, cutting machines, pneumatic chisels, nailers, and more. In the minimum configuration, the compressor unit is equipped with a supercharger (an engine that creates an air flow) and a receiver (a container for storing compressed gas). Compressors with a piston system electric motor have found the greatest application in car repair shops. In the supercharger crankcase, the transfer rod moves along the axis back and forth, giving the oscillatory moment to the reciprocating movement of the piston with O-rings. The bypass valve system located in the cylinder head works in such a way that when the piston moves downward, air is taken from the inlet pipe, and upward - it is returned to the outlet. The gas flow is directed to the receiver, where it is compacted. Due to its design, the blower produces an uneven air stream. Which is not applicable to spray gun use. A kind of condenser (receiver) saves the situation, which smooths out the pressure pulsations, giving out a uniform flow at the outlet. A more complex design of the compressor unit implies the attachment of additional equipment designed to provide automatic operation, dehumidification and humidification. And if in the case of a simple execution it is easy to localize a malfunction, then the complication of the equipment execution complicates the search. The following are the most common faults and remedies for the most common piston-type compressed gas systems. To make it easier to find the problem, all defects can be classified by the nature of the malfunction: Compressor unit blower does not start Compressor motor hums but does not pump air or fills air reservoir too slowly At start-up, the thermal protection circuit breaker is triggered or the mains fuse is blown out. When the blower is turned off, the pressure in the compressed air tank drops The thermal protection circuit breaker is periodically triggered Exhaust air contains a lot of moisture Engine vibrates violently Compressor runs intermittently Air flow is consumed below normal Let's consider all the causes of the problems and how to fix them. If the engine does not start and does not hum, then the supply voltage is not applied to it. First of all, using an indicator screwdriver, check the presence of "zero" and "phase", as well as the reliability of the plug-to-socket connection. In case of poor contact, measures are taken for a tighter fit. If there is 220 V at the input of the circuit, the fuses of the compressor unit look. Failed ones are replaced by passive protection devices of the same rating as defective ones. In no case are hot-melt inserts designed for a higher electric current allowed. If the fuse blows again, you should find out the cause of the failure - probably a short circuit at the input of the circuit. The second reason why the unit does not start is that the pressure control relay in the receiver is faulty or the level settings are out of order. To check, gas is released from the cylinder and the supercharger is tested. If the engine is running, the relay is reset. Otherwise, the defective part is replaced. Also, the engine will not start when the thermal overload circuit breaker is triggered. This device turns off the power supply circuit of the winding of the electrical device in case of overheating of the piston system, fraught with seizure of the motor. Let the blower cool down for at least 15 minutes. After this time has elapsed, restart it. With an underestimated mains voltage, the electric motor does not master the scrolling of the axis, while it will hum. With this malfunction, first of all, we check the voltage level in the network using a multimeter (it must be at least 220 V). If the voltage is normal, then the pressure in the receiver is probably too high, and the piston does not overpower the pushing of air.In this case, manufacturers recommend setting the “AUTO-OFF” automatic switch to the “OFF” position for 15 seconds and then moving it to the “AUTO” position. If this does not help, then the pressure control switch in the receiver is faulty or the bypass (check) valve is clogged. You can try to eliminate the last drawback by removing the cylinder head and cleaning the channels. Replace the defective relay or send it to a specialized center for repair. Compressor start-up is accompanied by blown fuse or activation of automatic thermal protection This malfunction occurs if the installed fuse is below the recommended rated power or the supply network is overloaded. In the first case, we check the compliance of the permissible currents, in the second, we disconnect part of the consumers from the electric main. A more serious cause of the malfunction is incorrect operation of the voltage relay or breakdown of the bypass valve. We bypass the relay contacts according to the scheme, if the engine is running, then the actuator is faulty. In this case, it is more advisable to contact an official service center for technical support or replace the relay yourself. A drop in compressed air pressure indicates that there is a leak somewhere in the system. Risk areas are: high pressure air line, piston head check valve or receiver outlet cock. We check the entire pipeline with a soapy solution for air leaks. We wrap the detected defects with sealing tape. The drain cock may leak if not properly closed or defective. If it is closed all the way, and the soapy solution is bubbling on the spout, then we change this part. When screwing in a new one, do not forget to wind up the fum tape on the thread. Read also: Do-it-yourself Samsung laptop battery repairIn the case of tightness of the air line and the exhaust valve, we conclude that the compressor control valve is not working correctly. For further work, be sure to bleed all the compressed air from the receiver! Next, we continue to repair the compressor with our own hands, disassembling the cylinder head. If there is dirt or mechanical damage to the bypass valve, we clean it and try to fix the defects. If the malfunction is not eliminated, then we replace the control valve. This defect occurs when the power supply voltage is too low, the air flow is poor, or the room temperature is too high. We measure the voltage in the network using a multimeter; it must be at least the lower limit of the range recommended by the manufacturer. Poor air flow into the discharge system is due to a clogged inlet filter. The filter should be replaced or washed according to the unit's maintenance manual. The piston engine is air-cooled and often overheats when in a poorly ventilated area. The problem is solved by moving the compressor unit to a room with good ventilation. This situation occurs under the following conditions: Large accumulation of moisture in the receiver Air intake filter dirty The humidity in the room of the compressor unit is increased Moisture in the output stream of compressed air is fought by the following methods: Drain excess fluid from the cylinder regularly Clean or replace the filter element Move the compressor unit to a room with drier air or install additional filter-moisture separators In general, piston engines are prone to high vibration. But, if the previously relatively quiet compressor unit begins to rumble, there is a high probability that the engine mounting screws are loosened or the material of the vibration cushions is worn out. This malfunction is eliminated by pulling all fasteners in a circle and replacing the polymer vibration isolators. Interruptions in the operation of the engine can be caused by incorrect operation of the pressure control switch or too intensive extraction of compressed air. Excessive gas consumption occurs due to a discrepancy between the compressor capacity and the power consumption. Therefore, before buying a new pneumatic tool, carefully study its characteristics and air consumption per unit of time. Consumers should not take more than 70% of the compressor capacity. If the power of the blower with a margin overlaps the requests of the pneumatic tools, then the pressure switch is faulty. We either repair it or replace it with a new one. This malfunction occurs as a result of a gas leak in the high pressure system or a clogged air intake filter. Air leakage can be minimized by pulling all butt joints and wrapping them with sealing tape. Sometimes it happens that when draining condensate from the receiver, they forget to completely close the drain valve, which also leads to a gas leak. This problem is easy to solve - by tightly closing the valve. If the dust filter is clogged, clean it or, even better, replace it with a new one. Most of the above malfunctions can be avoided by correctly carrying out the first start-up and running-in of the mechanisms, as well as performing regular routine maintenance. In order for the device to function properly for a long time, the recommended maintenance should be started at the initial stages of operation. Experts recommend the following actions from the date of purchase: Timely observance of these simple requirements will keep the mechanism in good condition. Such a time-consuming procedure as repairing a compressor with your own hands will be required extremely rarely. Proper grounding will avoid problems with the electrical part of the device. Regular replacement of oil and cleaning filters will prevent premature wear of rubbing parts. Start-up of the SO-7b compressor and check the actual performance.
