If the oil return of the screw chiller compressor is not smooth, it is a very headache. Generally speaking, the main reason for the poor oil return of the screw compressor is due to the phenomenon of gas mixture between lubricating oil and refrigerant during operation. Specifically, during the operation of the refrigeration system, encountering refrigerant and refrigeration machine lubricating oil immiscibility can cause the lubricating oil in the refrigeration compressor to be discharged into the condenser in the form of mist and droplet gas with the refrigerant during machine operation. If the oil separator is not effective or the system design is not good, it will cause poor separation efficiency and poor system oil return. Of course, the previous question was that you did not use fake oil. What are the impacts of a screw compressor not returning oil? If the screw compressor does not return oil, it will cause a large amount of lubricating oil to be stuck in the evaporator pipeline. When the oil film increases by 0.1mm, it will directly affect the cooling of the system. On the other hand, the machine is out of oil and cannot operate, requiring continuous replenishment of lubricating oil. This will lead to an accumulation of lubricating oil in the system, causing a vicious cycle, increasing operating costs, and reducing operational reliability. In general, it is allowed for the oil gas mixture to circulate in the system with a refrigerant gas flow rate of less than 1%. How to solve the problem of poor oil return in screw compressors? There are two ways for compressor oil return,
