Trouble and overhaul of piston refrigeration compressor

1. The refrigeration compressor cannot start normally Maintenance ideas 　　 1. First, check whether it is caused by low power supply voltage or poor connection of the motor circuit. If it is indeed that the grid voltage is too low, restart after the grid voltage returns to normal: If the line is in poor contact, the connection between the line and the motor should be detected and repaired.
