Information

A. Screw-type air compressor cannot be empty: The screw-type air compressor suddenly cannot be empty. Generally speaking, the failures that cause the screw-type air compressor to fail to empty mainly include the inlet valve failure and the pressure sensor failure. Work etc. Treatment method: 1. Find out the fault point 2. Scientific and reasonable maintenance is the fundamental to reduce the occurrence of faults

B. Exhaust temperature of screw air compressor is too high: * How to determine whether the exhaust temperature is too high? Under normal circumstances, if the exhaust temperature of a screw air compressor exceeds its design temperature and shuts down for protection, we call it excessive exhaust temperature. There are many reasons for the high exhaust temperature of the screw air compressor, and the common ones are as follows: 1. The temperature of the air compressor room is too high. Under normal circumstances, once the ambient temperature exceeds 40°C, we recommend that you shut down and rest immediately. 2. The temperature control valve fails and cannot work normally. 3. Insufficient oil supply of the screw air compressor results in poor cooling effect of the compressed air and high exhaust temperature. 4. The lubricating oil cooler lacks maintenance and has not been cleaned for a long time, resulting in poor cooling effect. 5. Clogged oil filter may also cause excessive exhaust temperature. 6. Cooling fan or cooling water problem. 7. The thermal resistance of the screw air compressor fails. Fault handling method: The best way to deal with this kind of fault is to prescribe the right medicine, find the cause of the fault, and solve the root cause of the problem from the root to completely solve the fault.

C. The oil content of the compressed air of the screw air compressor is too high: 1. The amount of lubricating oil is too high, and the amount of lubricating oil should be between the lowest scale line and the highest scale line. 2. The oil return pipe filter or the orifice is blocked, causing the lubricating oil to fail to return to the oil tank in time, resulting in poor separation of lubricating oil and compressed air, and finally the compressed air contains too high oil. 3. The oil and gas separator is blocked or damaged. The oil and gas cannot be separated normally. The oil content of the compressed air is too high. 4. Oil leakage in the oil adjustment system of the screw air compressor. 5. Too low exhaust pressure will also cause high oil content in compressed air
