Detailed product knowledge about Danfoss expansion valves

The thermal expansion valve is used to adjust the supply amount of liquid refrigerant in the evaporator. The supply amount is controlled by the superheat of the refrigerant. Therefore, this valve is particularly suitable for the supply of refrigerant liquid in the dry evaporator. Because the refrigerant superheat at the outlet of the dry evaporator is proportional to the load of the evaporator.

Excessive head resistance will cause compressor to trip

Excessive head resistance will cause compressor to trip The existence of compressor failure does not seem to have much to do with the brand. In other words, whether it is a Hitachi compressor, a Copeland compressor, or another brand of compressor, as long as it is used for a long time, there will be some problems of failure. . Compressor tripping is a common fault. When this failure usually occurs, we should comprehensively look for the cause of the failure.

Is air compressor lubricating oil the more viscous the better

Air compressor lubricating oil has many functions and effects such as cooling, sealing, lubrication, etc. It is a necessity during the use of air compressors. The good lubrication effect can not only give full play to the overall efficiency of the air compressor unit in operation, improve the efficiency of the equipment, but also reduce the failure rate and reduce the maintenance cost.

Explanation of the excellent performance of each component of the screw chiller

　The application of screw refrigeration compressors is becoming more and more common, and some of them have entered the period of frequent failures. When the abrasion of the female and male rotors, body, and exhaust end seat of the refrigeration compressor reaches above 0.65rnm, vibration will occur when the refrigeration compressor is running, the sound is abnormal, the cooling capacity is reduced, and the compressor cannot work normally.
