Air compressor in the operation of the sudden stop of the reasons are:
(1) The suction pressure is too low, lower than the pressure relay low pressure lower limit;
(2) Exhaust pressure is too high, causing high-voltage relay power failure;
(3) Oil pressure is too low, hydraulic relay action relay;
(4) Motor overload, thermal relay action relay.
Air compressor sudden shutdown method:
(1) Check the reason for the pipeline is blocked to smooth the pipeline, such as the lack of system to add the refrigerant;
(2) Check the condenser cooling or cooling air volume;
(3) Check the oil system piping and oil pump;
(4) Check the power supply voltage is low or the cooling load is too large.
