The oil-injected twin-screw air compressor is a common type of air compressor. The failure of the screw air compressor will affect its service life and the personal safety of the operator. Therefore, in industrial production, understand the common faults of the screw air compressor It seems very important.

In the process of using oil-injected twin-screw air compressors, we need to check the air compressor regularly to eliminate faults. Here is a brief introduction to the common faults of oil-injected screw air compressors.


1. Fault phenomenon: large current of the unit

   The main manifestations are: the voltage is too low; the wiring is loose; the unit pressure exceeds the rated pressure; the oil separation core is blocked; the contactor is faulty; the host is faulty; the main motor is faulty;

2. Failure phenomenon of screw air compressor: large oil consumption of the unit or large oil content of the compressed air

   The reason for this failure is that the amount of coolant is too much. The correct position should be observed when the unit is loaded. At this time, the oil level should not be higher than half; the blockage of the oil return pipe will also cause the failure of the screw air compressor; the installation of the oil return pipe is not correct. Meeting the requirements will cause the screw air compressor to consume too much oil; the exhaust pressure of the unit is too low when the unit is running; the rupture of the oil separation core will cause the screw air compressor to fail; the internal partition of the separation cylinder is damaged; the coolant is deteriorated or used for an extended period of time .

3. Failure phenomenon of screw air compressor: low unit pressure

   The reason for this failure is that the actual air consumption is greater than the output of the unit; the screw air compressor bleed and the intake valve are faulty (cannot be closed when loading); the transmission system is abnormal, the ambient temperature is too high, and the air filter is blocked; load Solenoid valve (1SV) failure;  user pipe network leakage; pressure sensor, pressure gauge, pressure switch and other screw air compressor failure will cause low unit pressure; pressure sensor or pressure gauge input hose leakage ;

4. Failure phenomenon of screw air compressor: fan motor overload

   The fan is deformed; the fan motor is faulty; the thermal relay of the fan motor is faulty (aging); the wiring is loose; the cooler is blocked; the exhaust resistance is large.
