Problems solved by technology

[0008]However, the above-mentioned screw compressor not only has a complex structure, a large number of parts, but also has low oil separation efficiency, and can only meet the requirements of low oil content. system, and for flooded systems with higher oil content requirements, the oil separation effect of screw compressors in the prior art is generally poor, so it is difficult to achieve the optimum separation and recycling of the refrigerated oil inside the screw compressor optimization

Abstract

The present invention relates to a screw compressor having an oil separator, comprising: a compressor housing with an inlet for a refrigerant gas flow to flow in; an oil separator housing connected to the compressor housing in a fastened and sealed manner and having an outlet for the refrigerant gas flow to flow out; a compressing assembly disposed within the compressor housing and close to the inlet for compressing the refrigerant gas flow; an electric motor for driving the compressing assembly; and an oil supply device for supplying a freezing oil to the compressing assembly; the screw compressor further comprises an oil separator, the oil separator is disposed within the oil separator housing and comprises a first separator and a second separator, wherein the second separator is disposed close to the outlet, and the first separator is disposed between the compressing assembly and the second separator.

Description

technical field [0001] The invention relates to a screw compressor with an oil separator, and also relates to a chiller equipped with the screw compressor. Background technique [0002] The Chinese patent application CN202792748 disclosed by Dong Ling proposes a casing cyclone oil separator. The casing cyclone oil separator disclosed in this patent for screw compression heat pumps includes an oil storage cylinder and a porous plate, and is characterized in that it also includes a separation cylinder and a casing cyclone oil separator, and the separation cylinder is located in the oil storage cylinder. In the upper part, one end of the oil storage cylinder is equipped with a porous plate inside, and several groups of identical casing cyclone oil separators are installed in the separation cylinder. The inner and outer tubes are installed coaxially and vertically, the inner tube is short and is a central passage, the outer tube and the inner tube form an annular space, the to...
