The compressor is the heart of the refrigeration system. It inhales low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges the high-temperature and high-pressure refrigerant liquid to the exhaust pipe to provide power for the refrigeration cycle. 

Thereby, a refrigeration cycle of compression-condensation-expansion-evaporation (heat absorption) is realized.

? ? Let's take a look at common compressor faults and troubleshooting methods:

一、The compressor suddenly stops during operation:

1. The reasons for the sudden shutdown of the compressor during operation are as follows:

     ? (1) The suction pressure is too low, lower than the low pressure lower limit of the pressure relay;

     ?(2) The exhaust pressure is too high, causing the high-voltage relay to act and cut off;

     ? (3) The oil pressure is too low, and the oil pressure relay acts as a relay;

     ?(4) The motor is overloaded, and the thermal relay acts as a relay;

2. Remedy for sudden shutdown of the compressor during operation:

    ?(1) Check the reasons. If the pipeline is blocked, the pipeline should be unblocked. If the refrigerant in the system is insufficient, supplement it;

    ?(2) Check the cooling capacity or cooling air capacity of the condenser;

    ? (3) Check the pipelines and oil pumps of the oil delivery system;

    ?(4) Check whether the power supply voltage is too low or the cooling load is too large
