Oil-free air compressor is a kind of high efficiency and energy saving air compressor. Due to its special working principle, it often encounters some minor faults. Here, I will introduce some common oil-free air compressor failures for you, and provide corresponding solutions to help you better maintain and use this equipment.
1. Pressure instability: If the oil-free air compressor encounters pressure instability during operation, it may be caused by the following reasons:
- Air inlet blockage: Check whether there is foreign matter or dust obstruction in the air inlet, and clean up in time.
- Oil and gas separator fault: Check whether the oil and gas separator is damaged and needs to be replaced.
- Oil filter blockage: Check whether the oil filter is blocked, and clean or replace it if necessary.
- Motor failure: Check whether the motor is working properly and if necessary, repair or replace it.
2. Too high pressure: If the outlet pressure of the oil-free air compressor is too high, it may be caused by the following reasons:
- High pressure valve fault: Check whether the high pressure valve is damaged and needs to be replaced.
- Improper pressure switch adjustment: Check the adjustment parameters of the pressure switch and adjust the pressure properly.
- Blocked outlet pipe: Check whether the outlet pipe is blocked by foreign matter and needs to be cleaned.
3. Too low pressure: If the outlet pressure of the oil-free air compressor is too low, it may be caused by the following reasons:
- Air leakage: Check whether there is a gas leak in the air compressor, and the leak point needs to be repaired.
- Air intake blocked: Check whether the air intake is blocked and needs to be cleaned.
- Air filter blockage: Check whether the air filter is blocked, and if necessary, clean or replace it.
4. Abnormal noise: If the oil-free air compressor makes abnormal noise during operation, it may be caused by the following reasons:
- Motor failure: Check whether the motor is working properly and if necessary, repair or replace it.
- High pressure valve fault: Check whether the high pressure valve is damaged and needs to be replaced.
- Bearing failure: Check whether the bearing is worn or damaged, and if necessary repair or replacement.
5. The operating temperature is too high: If the temperature of the oil-free air compressor is too high during operation, it may be caused by the following reasons:
- Cooling fan failure: Check whether the cooling fan is working properly. If necessary, repair or replace it.
- Oil and gas separator fault: Check whether the oil and gas separator is damaged and needs to be replaced.
- Cooler blockage: Check the cooler for dust accumulation and need to be cleaned.
6. Oil pollution: During the use of oil-free air compressors, if oil pollution is found, it may be caused by the following reasons:
- Oil and gas separator fault: Check whether the oil and gas separator is damaged and needs to be replaced.
- Oil filter blockage: Check whether the oil filter is blocked, and clean or replace it if necessary.
- Oil return pipe is blocked: Check whether the oil return pipe is blocked by foreign matter and needs to be cleaned.
7. Electrical failure: If an electrical failure occurs during the operation of the oil-free air compressor, it may be caused by the following reasons:
- Power failure: Check whether the power supply is normal. If necessary, repair or replace it.
- Switch failure: Check whether the switch is working properly, and repair or replace it if necessary.
- Motor failure: Check whether the motor is in normal operation, if necessary to repair or replace.
In summary, the common minor faults of oil-free air compressors include pressure instability, high or low pressure, abnormal noise, high operating temperature, oil pollution and electrical failure. When these problems are encountered, they can be solved by checking and servicing the corresponding parts. At the same time, regular maintenance and maintenance work is also the key to maintaining the normal operation of oil-free air compressors.
