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.

What's wrong with the freezer not cooling

There are four main reasons: the first is the lack of refrigerant and the compressor has problems; the second is the problem of the power cord of the freezer; the third is the frost in the evaporator of the freezer; the fourth is that the storage in the freezer is too full. Of course, no matter what the reason is, you should find a professional to help repair the loophole or add refrigerant.

Hitachi water source heat pump compressor

How does the air conditioning compressor work? The air-conditioning compressor is also called a rotary (rotor) compressor, and its working principle is to rely on an eccentric rotor under the action of spring force, the compressor, and the eccentric rotor are always in contact with the container separated by the sliding container Changes to achieve a process of compression. When the eccentric rotor rotates, the volume of the container changes and the gas is compressed.

How to adjust the capacity of refrigeration compressor

How to adjust the capacity of refrigeration compressor The capacity of the compressor is determined according to the maximum production of BOG in the storage tank. After the compressor is selected, its capacity is constant. If the amount of inhaled air is greater than the amount of BOG produced in the tank, the tank pressure will drop.
