Abstract

The invention discloses a three-stage separated efficient horizontal type oil distribution device which comprises multiple screw compressors. Each screw compressor is connected with an inlet of a horizontal type oil separator through an exhaust branch, an outlet of the horizontal type oil separator is connected with an inlet of a condenser through a pipe, an outlet of the condenser 3 is connected with a low-pressure circulating bucket through a pipe, a throttle valve is arranged between the condenser and the low-pressure circulating bucket, the bottom of the low-pressure circulating bucket is connected with an evaporator through a fluorine pump, an outlet of the evaporator is connected with the low-pressure circulating bucket through a pipe, and a return air pipe of the low-pressure circulating bucket is connected with the compressors. The three-stage separated efficient horizontal type oil distribution device has the advantages of improving the oil distribution efficiency, achieving 10 PPM, effectively decreasing frozen oil entering a low-pressure system and accordingly improving the working efficiency of a parallelly connected compressor unit.

Description

technical field [0001] The invention discloses an oil separation device of a refrigeration system, in particular a three-stage separation type high-efficiency horizontal oil separation device. Background technique [0002] When the screw refrigeration compressor is working, it needs to spray a large amount of lubricating oil. The lubricating oil not only lubricates the bearing, but also forms an oil film between the screw and the cylinder wall to play a sealing role. Due to the large amount of oil injected, a large amount of lubricating oil is mixed in the high-pressure steam discharged from the screw compressor. Because the oil forms an oil film on the inner wall of the heat exchanger, the heat transfer effect and refrigeration efficiency are greatly reduced. The oil separator is the device that separates the oil from the refrigerant. Especially in flooded systems supplied by barrel pumps, the design of the oil separation device is particularly important.
