The common reasons for this failure are as follows: 1. The host is faulty. 2. The exhaust pressure is too high. Three. The voltage is too low: the power of the general oil-free air compressor is rated. Therefore, according to the formula, the voltage is too low and the current is too high. This is understandable. The high scheduling pressure is caused by many factors, such as: the intake valve is blocked and cannot be closed, resulting in constant loading. There is a sudden drop in gas consumption, loading solenoid valve failure, blockage, but not all of the blockage and unloading solenoid valve failure, resulting in unloading failure unloading pressure continues to rise to unloading, pressure setting is too high, pressure sensor failure, and the main engine failure is MOS. Due to the maintenance of minor faults is not timely, so the host also needs to pay attention to maintenance.

The reasons for the failure are as follows: 1. Start capacitor leakage, when a leak occurs, you can also start the compressor head, but the speed is slow and the current is large. Due to the high current, the machine's hair is hot and fast, and the nose will not be turned off. This question can be replaced with a new one, but it should be noted that the UF number should be the same. Too big or too small is bad. 2. Undervoltage: Hum when turned on. For example, the working current is too large at this time, the lower working voltage of the oil-free engine head is 200V, and it is difficult to start under this voltage head. Frequent activation can lead to an increase in head temperature. Final circuit protection off. Turn it on until the temperature drops. For areas with frequent voltage fluctuations, an automatic voltage regulator is recommended.

The reasons for the failure are as follows: 1. The fixed devices or accessories of the air compressor are loose. 2. The working current is abnormal. Three. The motor bearing is badly worn. 4. The cup is broken. These problems can largely be avoided with regular inspections and maintenance. The above are common problems and preventive measures of oil-free air compressors
