How does a screw compressor work?

A screw compressor can run loaded ('pumping air') or unloaded ('idle'). The inlet/loading valve opens and closes according to air demand. The inlet valve is controlled by a solenoid valve that supplies control air to the inlet/loading valve. Check solenoid valve coil and solenoid valve operation.

What should I do if my air compressor is too low?

If the capacity of the air compressor is really too low, check the following: Check differential pressure over oil separator. Replace separator when necessary. Check and replace compressed air filters (if installed). Compressor does not unload. Check if pressure switch is correctly set and working.

How to check air compressor temperature?

Compressor temperature: The temperature of the oil and gas mixture at the outlet of the compressor reaches 120°C. Solution: Keep the air compressor well ventilated, check that the radiator is not covered by debris, and that the radiator has good heat dissipation. Check the air compressor oil level, cooling fan, and temperature sensor. 4).

How do I know if my air compressor is working?

If you have a compressed air dryer, check the dewpoint. Check the current draw with a current clamp meter. If the motor draws exeessive current: Try to turn the compressor by hand. It should be possible to turn it around. It should turn around smoothly, without any 'hickups' (be sure to completely shut down the air compressor!).

Why does my air compressor have a steering error?

Treatment method: contact maintenance or manufacturer. 7). Motor steering error: The motor wiring is wrong or the star/delta cannot be switched normally when the motor starts, and the steering signal sensor on the compressor body is faulty, causing the air compressor to report the motor steering error.
