First, the current is too large, the common causes of such faults are as follows:
1. The main compressor fails
2. The exhaust pressure is too high
4.Low voltage: generally oil-free air compressor power is rated power, so once voltage low too much will inevitably cause the current to be too high.
Second, insufficient gas supply:
1. Air leakage
2. the cup is worn: the general leather cup life is about 3 years.
3. Machine overload
4. Exceed the rated flow rate
Third, the oil-free air compressor works intermittently, and the gas supply is insufficient :
1. Capacitor leakage
2.Insufficient voltage
Fourth, high noise during operation:
1. The air compressor fixture or accessory is loose
2. Abnormal operating current
3. The motor bearing is seriously worn
4. The leather cup is damaged
