The most prone faults and solutions in the daily maintenance of screw air compressors

1. The air compressor cannot be started for no reason

Check for control voltage. If not, you need to check whether the fuse is intact; if there is a control voltage, check whether the control relay and time relay are operating normally.

2. Abnormal air supply from the air compressor

Check whether the control oil cylinder is moving, there is action, check whether the butterfly valve has mechanical failure; if there is no failure, check whether the loaded electromagnetic ISV coil has suction; after removing the mechanical failure of the ISV solenoid valve and the coil failure, check the sub-circuits where the solenoid valve ISV is located one by one. screw air compressor parts

3. The exhaust pressure of the air compressor is too low

Check the pressure before and after the separation, check whether the gas pipeline is leaking, whether the butterfly valve is fully opened, whether the intake regulator is working properly, whether the solenoid valve 3SV, 8SV is leaking, whether the pressure switch IPS needs to be re-adjusted, etc.

4. The air compressor stops automatically during operation

First, check whether the machine automatically stops normally; then check whether the automatic switch and thermal relay act, whether the cooling fan motor stops, or the exhaust temperature is too high, or the pressure is too high, and whether the motor voltage is normal.

5. The exhaust temperature of the air compressor is too high

Firstly check whether the ambient temperature, compressor lubricating oil, oil level, oil quality, refrigerating fan, etc. are normal; then check whether the oil cooler and aftercooler are clean, and whether the temperature control valve components, the voltage of the oil cut-off solenoid valve and the valve body are normal , If the diaphragm is damaged, the temperature control valve core does not work, etc., it needs to be replaced; finally, check whether the oil filter is dirty or needs to be replaced. The exhaust temperature is normally 80～95℃. screw air compressor parts

6. The air compressor does not start smoothly

The screw air compressor will stop automatically a few seconds after starting up. It is recommended to check whether the switch is tripped, whether the voltage is normal, whether the closing degree of the intake butterfly valve is normal, and whether the contactor and the motor are normal in the Y-△ starting.

7. The air compressor is shut down due to fuel injection at the inlet

First check whether the oil cut solenoid valve 5SV has voltage and whether the mechanical part is normal; if it is normal, check the check valve and reassemble or replace it. screw air compressor parts
