What are the reasons for the lack of oil in the compressor?
The compressor is a complex machine running at high speed. Ensuring sufficient lubrication of moving parts such as compressor crankshafts, bearings, connecting rods, pistons, etc. is the basic requirement for maintaining the normal operation of the machine. For this reason, compressor manufacturers require the use of designated brands of lubricating oil and require regular inspections of the oil level and color of the lubricating oil.
Lack of oil is one of the compressor faults that are easy to identify. When the compressor is out of oil, there is little or no oil in the crankcase. advantages of rotary compressor
The compressor is a special air pump, a large amount of refrigerant gas is discharged while also entraining a small part of lubricating oil (called running oil or running oil). Compressor rushing is inevitable, but the speed of rushing is different. advantages of rotary compressor
There is approximately 2-3% of the lubricating oil in the exhaust gas of a semi-hermetic piston compressor, and 0.5-1% of a scroll compressor. For a 6-cylinder compressor with a displacement of 100m3/hr and a crankcase oil storage capacity of 6 liters, 3% oil rushing means about 0.3-0.8 liters/min of oil rushing, or the compressor runs without oil return The time is ten minutes. If the lubricating oil discharged from the compressor does not return, the compressor will be short of oil. advantages of rotary compressor
