Screw air compressors will have some common problems and failures in the long-term operation. It is timely found that timely maintenance can reduce the loss of production operations.

And how to find out in time is the most important thing, here are the common faults of air compressors:
1. When the machine is shut down, the air inlet of the screw air compressor will spray oil outward.
When the air compressor suddenly stops and does not open the exhaust valve exhaust gas in time, the air inlet is sprayed with cooling oil. At this time, first check whether the intake valve is faulty and cannot be closed normally. The second check is whether the oil shut-off solenoid valve is closed. Fault, if it is normal, it should be further checked whether the main exhaust pipe upper check valve can be closed or closed in time, if it is faulty, it should be eliminated one by one.
Second, the screw air compressor is automatically stopped during the operation. There are several reasons for the automatic trip of the machine during operation:
1. Power grid factors.
Because the machine itself has an Undervoltage protector, fault phase protector, high voltage protector, and other safety protection devices. When the grid voltage is lower than the rated voltage (380V) by about 90%, or when the power phase sequence is incorrect and the three-phase power supply is out of phase, it will automatically trip and stop.

2. The exhaust temperature is too high.
There may be a lack of lubricant, a blocked cooler, or a malfunction of the temperature control valve.

3. The exhaust pressure is too low.
First check if the intake valve is fully open and the current is within the normal range. Then check if the external air volume is increased or if there is a leak.

4. The temperature is too high.
This is the most common failure of screw air compressors, which is described in detail here. The screw air compressor sets the maximum exhaust temperature to 120 degrees Celsius. When the temperature reaches 110 degrees, the temperature warning light starts to flash an alarm. When it exceeds 120 degrees, it will automatically stop. Therefore, the daily operation needs to pay attention to the operating temperature of the air compressor.
