You must know the main reasons and solutions for refrigeration compressor oil return

During the operation of the system, the lubricating oil is discharged from the compressor along with the refrigerant, and then returns to the compressor after circulating. Then there will be lubricating oil coming in and out of the place where the refrigeﰸ2䀀

The main circuit fuse fusing is a common fault of SCR servo driver. The causes of fuse fusing are as follows

The "phase sequence" of power incoming line is incorrect. Due to the synchronization problem between the trigger pulse and the main circuit of SCR servo driver, there are strict requirements on the "phase sequence" of the input power supply. If the "phase sequence" is not correct, connecting the power supply may immediately cause the fuse of the main circuit of the driver to blow.

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
