A coup to avoid the oil return problem of the refrigeration compressor of the piston chiller

Compressor: It is a complex machine running at high speed. Ensuring adequate 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 specified grades of lubricating oil, and require regular inspection of the lubricating oil level and color
