ZEGA screw air compressor automatic shutdown fault handling method

General enterprise air compressor maintenance equipment, the daily maintenance of the air compressor is a very important link, but still can not avoid the machine in use without warning of the shutdown, the loss of benefits is very large, in the daily must learn the machine inspection maintenance and other aspects, the following is for the air compressor automatic shutdown fault analysis and processing analysis, let's take a look!

Automatic shutdown failure analysis after air compressor loading:

　　First, check whether the voltage is normal. If it is incorrect, it needs to be improved.

　　Second, whether the wiring of ZEGA screw air compressor is loose. Connect the wiring well.

　　Third, the loading solenoid valve is pulled out to see if it still has a shutdown failure. If not, it means that the solenoid valve is short-circuited, and then we only need to replace the solenoid valve.

　　Fourth, check the motor and the contactor in the middle, the contactor can not be sucked, to load and stop, if there is no problem with the contactor, that is, the circuit board pulse signal can not maintain the suction sum. Replace the board.

　　Fifth, the problem of the control panel of the ZEGA screw air compressor, the output signal can not maintain the suction of the contactor, as soon as it is loaded, it will stop, and the ZEGA screw air compressor stops without warning and for no reason, and suddenly stops, without showing any fault.

　 Cause analysis and treatment:

　　1. The emergency stop button of ZEGA screw air compressor is faulty. In the past two years, this situation often occurs (emergency stop button batch problem), without warning, the air compressor stopped, everything was checked without problems, and as a result, the emergency stop button was short-connected, and the emergency stop button could be replaced.

　　2. Zhigao screw air compressor external air opening action. The air open has a long time of use, poor contact, and it is most likely to appear in the operation of the air compressor, especially when the star angle switch has just been started. It is also possible that the electrical system of the air compressor fails, such as the contactor contact is not good, the motor bearing failure, the air compressor somewhere short circuit, etc. There may be a sudden shutdown problem, the probability of occurrence is relatively small, this kind of failure The air compressor is powered off, and the replacement of the air can solve this problem.

　　3. The maintenance time of ZEGA screw air compressor is here. This situation is generally foreshadowed, before the shutdown will generally have a display prompt oil filter maintenance time to arrive, air filter maintenance time to arrive, etc., the display fault light will flash (air compressor maintenance 100 hours from the set time Air compressor prompt, more than 100 hours machine will stop). If your red five-ring screw machine bought earlier, it is Emerson, Schneider main controller, there may be a shutdown on the display screen without prompting the maintenance time, and you have to enter the menu to see that the maintenance time is up. In the above cases, as long as the air compressor maintenance time is reset, it can continue to be used.
