Impact of lack of oil on the compressor
Classification: Common Faults
Time：2017-10-14 18:21
The compressor is a complex machine running at high speed. Ensuring the sufficient lubrication of the compressor crankshaft, bearings, connecting rods, pistons and other moving parts is the basic requirement to maintain the normal operation of the machine. For this reason, compressor manufacturers require the use of specified grades of lubricating oil and require regular inspection of the lubricating oil level and color. However, due to negligence in the design, construction and maintenance of the refrigeration system, it is common that the compressor is short of oil, oil coking and deterioration, backflow dilution, refrigerant flushing, and the use of inferior lubricating oil cause insufficient lubrication of moving parts. Insufficient lubrication will cause the bearing surface to wear or scratch, and in severe cases, it will cause the shaft to be held, the piston stuck in the cylinder, and the resulting connecting rod bending and fracture accidents.
