Causes and Solutions of Air Compressor Solenoid Valve Leakage

Reasons for air compressor solenoid valve leakage and solutions Reason 1: When the air compressor is in continuous operation, the body temperature is too high or the indoor temperature is too high, causing the solenoid valve coil to burn out or the line to break. This is also the air compressor solenoid valve. Cause of air leakage. Reason 2: When the solenoid valve is in a frequent start and stop state, the internal pilot head will be damaged. Solution: 1. The solenoid valve should be replaced in time, and indoor cooling measures should be taken. 2. The pilot head or solenoid valve should be replaced in time. 3. First, reset the gas vent pressure inside the air compressor tank to zero, unscrew the outer hexagonal cover of the corresponding one-way valve, and check whether iron filings are stuck on the internal valve core. The iron filings should be removed in time and the valve should be wiped with alcohol. core surface and reinstall it. Solenoid valves are widely used in our production. We have also encountered many problems related to solenoid valves during the maintenance of screw air compressor production, such as solenoid valve stuck, air leakage, etc. The following is a summary of common solenoid valve failures and solutions. 1. When the air compressor runs for a long time, the rapid temperature rise of the unit causes the solenoid valve coil to burn or break. At this time, the solenoid valve should be replaced in time and cooling measures should be taken;2. Because the solenoid valve frequently starts and stops, causing damage to the internal pilot head, the pilot head or solenoid valve should be replaced in time. Solution: First, reset the exhaust pressure in the air compressor gas tank to zero, unscrew the outer hexagonal cover of the corresponding one-way valve, check whether the iron filings are stuck on the inner valve core, remove the iron filings in time, and wipe the valve with alcohol. Core surface, reinstall. The leakage of the solenoid valve can be eliminated and solved according to the above methods. During the operation of the air compressor, the solenoid valve will also have the following faults: (1) The solenoid valve connector is loose or the thread is loose, and power is not allowed, but the thread can be tightened. (2) The solenoid valve coil is burned out. Disconnect the wiring from the solenoid valve and measure it with a multimeter. If the circuit is open, the solenoid valve coil will burn out. The main reason: the coil gets damp, causing poor insulation and magnetic leakage, resulting in excessive coil current. Rainwater must be prevented from entering the solenoid valve of the air compressor during operation. In addition, if the spring is too hard, the reaction force will increase and the number of turns of the coil will be small, the suction force will not be enough, and the coil will be burned out. During emergency treatment, the manual button on the coil can turn from 0 to 1 to open the valve during normal operation. (3) The solenoid valve is stuck. The fitting gap between the slide valve sleeve and the solenoid valve core is small, and they are usually assembled in one piece. When impurities enter or there is too little lubricating oil, it is easy to get stuck. The solution is to pass a steel wire through the small hole in the head to make it bounce back. The fundamental solution is to remove the solenoid valve, take out the valve core and valve core sleeve, and clean it with cleaning agent to make the valve core move flexibly in the valve core sleeve. Pay attention to the order when disassembling. Secondly, check whether the oil spray hole of the oil mist injector is blocked and whether the lubricating oil is sufficient.
