Introduction to common faults and maintenance methods of air compressors

Common faults and repair methods: 1. The exhaust temperature is too high, check whether the coolant is sufficient, whether the radiator is blocked, and whether the temperature control valve is working normally; 2. The compressor stops during operation, and you need to check the power supply and gas supply. bottle pressure; 3. The air compressor cannot pump out air. You need to check whether the pressure switch is damaged, whether the contacts are in good contact, whether the diaphragm is ruptured, etc.; 4. The exhaust pressure is low, check whether the air inlet valve is fully open, and whether the exhaust pipe is Check whether the air filter is blocked; 5. It is difficult to start the air compressor. Check whether the motor and power supply are normal, whether the motor is reversed, whether the motor is missing phase, etc.

Common faults and maintenance methods of air compressors are as follows:

1. The exhaust temperature is too high High: Check whether the coolant is sufficient, whether the radiator is blocked, whether the temperature control valve is working properly, and replace related accessories if necessary.

2. The compressor stops during operation: It may be a power failure or low air pressure. You need to check the power supply and cylinder pressure.

3. The air compressor cannot pump air: you need to check whether the pressure switch is damaged, whether the contacts are in good contact, whether the diaphragm is ruptured, etc. You need to replace related accessories.

4. Low exhaust pressure: Check whether the intake valve is fully open, whether the exhaust pipe is clear, whether the air filter is blocked, and replace relevant accessories if necessary.

5. It is difficult to start the air compressor: it is necessary to check whether the motor and power supply are normal, whether the motor is reversed, whether the motor is missing a phase, whether the motor is overloaded, and relevant accessories need to be replaced.

6. Air compressor oil leakage: Check whether the oil seal is damaged, whether the oil pipe joint is loose, and relevant accessories need to be replaced.

7. The air compressor makes abnormal noise: it is necessary to check whether the connecting rod bush and crankshaft bush are severely worn, whether the piston and piston ring are severely worn, and replace relevant accessories if necessary.

8. The safety valve frequently trips: it is necessary to check whether the gas contains too many impurities, whether the safety valve is loose, and relevant accessories need to be replaced.

It should be noted that when repairing the air compressor, it is necessary to follow the relevant operating specifications to avoid safety accidents. At the same time, in order to ensure the normal operation of the air compressor, regular maintenance is required.
