Solutions to Copeland Compressor Insufficient Lubrication Failure Performance

Solutions to Copeland Compressor Insufficient Lubrication Failure Performance Copeland compressor If the lubrication is insufficient, the direct cause of wear is the lack of smoothness. The lack of oil will definitely lead to lack of smoothness, but the lack of oil is not necessarily caused by lack of oil. The following three reasons can also constitute a lack of smoothness: smooth oil cannot reach the bearing surface; although the smooth oil has reached the bearing surface, but the viscosity is too small to form an oil film that meets the thickness; although the smooth oil has reached the bearing surface, it is differentiated due to overheating If it is dropped, it will not be smooth. Blockage of the oil suction network or oil supply pipeline, faults of the oil pump, etc. will affect the delivery of the smooth oil, and the smooth oil cannot reach the conflict surface away from the oil pump. The oil suction net and the oil pump are normal, but the bearing wear, excessive gaps, etc. constitute oil leakage and the oil pressure is too low, which will prevent smooth oil from the conflicting surface away from the oil pump, which causes wear and scratches. Liquid return is a common system question, and one of the major drawbacks of liquid return is the dilution of smooth oil. After the diluted smooth oil reaches the conflict surface, the viscosity is low, and it cannot form a protective oil film of sufficient thickness, which will cause wear overnight. When the amount of liquid returned is relatively large, the smooth oil will be very thin, not only can not play a smooth effect, but also will dissolve and wash the original oil film, causing the refrigerant to wash.
