General enterprise in the air compressor maintenance equipment, maintenance of air compressor is a very important link, but I still can't avoid using the machine, shut down without warning in the interests of the loss is very big, must learn to machine in the daily inspection maintenance and other aspects, the following is for air compressor fault analysis, parsing and processing automatic stop Take a look!
Screw air compressor automatic shutdown troubleshooting method
Fault analysis of automatic shutdown after loading of air compressor:
First, check whether the voltage is normal. If not correct, need to improve.
Two, screw air compressor wiring is loose. Connect the wiring well.
Three, load the solenoid valve unplug, see if it still exists shutdown fault. If not, it means that the solenoid valve short circuit, then we only need to replace the solenoid valve.
Four, check the motor and the middle of the contactor, the contactor suction and not, to load the shutdown, if there is no problem with the contactor, that is, the circuit board pulse signal does not keep suction and. Replace the circuit board.
Five, screw air compressor control panel problems, the output signal can not maintain the suction of the contactor, as soon as the load will stop, screw air compressor without warning for no reason, suddenly stopped, did not show any fault.
