Title:
COMPRESSOR WITH OIL BALANCING PIPE, PARALLEL-TYPE COMPRESSOR UNIT, AND OIL BALANCING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/091126
Kind Code:
A1
Abstract:
Provided are a compressor with an oil balancing pipe, a parallel-type compressor unit, and an oil balancing method. The compressor comprises at least one oil balancing pipe (14), wherein an opening at one end of the oil balancing pipe (14) is provided at a target oil level of an oil sump (13), and an opening at the other end thereof is provided in a suction port (11). When the oil level of the oil sump (13) of the compressor is higher than the target oil level, surplus oil enters the suction port (11) via the oil balancing pipe (14). When the compressor operates, due to gas flow in the suction port (11), a pressure in the suction port (11) is less than a surface gas pressure of the oil sump (13), and when the oil level of the oil sump (13) of the compressor is higher than the target oil level, under the action of a differential pressure, the surplus oil enters the suction port (11) via the oil balancing pipe (14), and part of the oil enters a vortex and is drained out of the compressor from an exhaust port (12), and the oil drained out of the compressor returns to another compressor, that is short of oil, through a pipeline, thus realizing oil balance between different compressors.
