Six aspects of repair and maintenance of refrigeration compressors in cold storage

A. During the initial operation of the cold storage unit, carefully observe the oil return of the compressor and keep it clean. If you find that the oil level is not clean enough or if the oil level drops, you should add oil or replace it with new oil in time. This can avoid poor lubrication

Reasonably adjust the cold storage evaporator and defrost in time

Reasonably adjust the cold storage evaporator and defrost in time Generally speaking, every increase in the cold storage evaporation temperature can save energy Therefore, under the premise of satisfying the low refrigeration process of the product, the evaporation temperature can be increased as much as possible by adjusting the amount of liquid supplied. The thermal resistance of the frost layer is generally much larger than the thermal resistance of the steel pipe.

The working principle and the common wiring method of the servo drive

The servo drives, the motor under the command signal from a control system, so whether the drive can work normally or not directly affects the overall performance of the equipment. In the servo control system, the servo drive is equivalent to the brain, and the servo motor is equivalent to the hands and feet.
