When the compressor leaks, the emer

When the compressor leaks, the emergence of refrigerant can be observed. The reason may be that the oil seal, pipe joint, etc. Use the leak detector to check the fault area and replace the seal. When the annual leakage is less than 15g, there is no need to repair. The refrigerant output of the compressor disappears or the compression rate decreases due to internal leakage of the compressor. This is shown as follows. Confirm the suction and exhaust pressure of the compressor with the pressure gauge. The two pressures are basically the same. Since the compressor cylinder is helium, the high-pressure and high-temperature steam from the exhaust valve returns to the suction chamber through the gap of the syringe gasket. The steam temperature is higher and higher, and finally the refrigerant oil burns. The compressor is damaged.
