Why does the compressor produce liquid shock?
The cause of a liquid shock in the compressor is:1, excessive refrigerant filling, or throttle valve is too large, or throttle valve failure.2, the unit evaporation area is too small, and the refrigeration capacity of the compressor does not match.3, the cooling area of the evaporator is reduced and the heat transfer is reduced when the evaporator surface is seriously wrapped with frost.4, the compressor has just started operation, because the evaporation temperature is higher at the beginning, and the compressor suction valve is too fast, causing sudden inhalation.5, freon compressor lubricating oil temperature is too low, will work medium in lubricating oil dissolved too much, when the compressor suction, suction pressure drop suddenly. At this point, the oil dissolved in the oil will suddenly evaporate, so that the oil bubble, oil will be inhaled along with the refrigerant in the compressor and cause liquid shock.Liquid hammer occurs mainly in piston compressors. As refrigerant liquid (or lubricating oil) is sucked in by compressor, the liquid is incompressible, which results in abnormal shock of compressor.
Low pressure suction should be gas, once inhaled liquid, there will be liquid shock, resulting in damage to the connecting rod or valve, the cause of the pipeline problems!
