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

How to prevent the refrigeration compressor from reversing

Reverse rotation is strictly prohibited after the refrigeration compressor is stopped. When the compressor rotor is stationary, there is still a large volume of process gas remaining in the pipeline and has a certain pressure

How to deal with the high pressure overload of the chiller

When the condenser heat dissipation is poor, the compressor efficiency is low and the operating current increases. When the high pressure rises to 19Kg/cm2, the compressor trips under the protection of the high pressure switch and the compressor stops runPﰨ2

Selection guide for air compressor

Selection of working pressure (exhaust pressure): When the user is preparing to purchase an air compressor, first determine the working pressure required by the air end, add a margin of 1-2 bar, and then select the pressure of the air compressor (the margin is considered from the air compressor The pressure loss from the installation site to the actual gas end pipeline distance, according to the length of the distance between 1-2 bar, appropriately consider the pressure margin)

Operation method of air discharge in refrigeration system of industrial chiller

Air is a non-condensable gas, which means that air will not condense into liquid at ordinary low temperatures. If air is mixed into the refrigeration system of an industrial chiller, it will affect the heat dissipation of the condenser and increase the co¨ﰨ2䀀湠疨V
