What are the specific operation methods for the maintenance of cold storage screw compressors?

　 Before the cold storage screw compressor must be overhauled, if possible, unload the slide valve to the "0" position, shut down normally, and cut off the power supply. The pipeline connected to the compressor should be cut off and the refrigerant and lubricating oil in the compressor should be discharged before the compressor can be disassembled.
