1.When the screw air compressor exits, it 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 in use. If it is normal, it should be further checked whether the check valve on the main exhaust pipe can be closed or closed in time. If it is faulty, it should be eliminated.
2.Automatic stop of screw air compressor in operation
There are two main reasons why the machine automatically trips during operation:
The first is the power grid factor. Because the machine itself has 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.
Second, the exhaust temperature is too high. It may be that the lubricant is missing, the cooler is clogged, or the temperature control valve fails to operate normally.
