Problems solved by technology

When the parallel compressor unit operates under high flow conditions, the oil cannot flow back to the oil pool at the lower part of the compressor due to the high velocity of the upward airflow, and the oil level of the operating compressor will continue to be kept at a low oil level, which is easy The risk of compressor failure due to lack of oil

Abstract

The invention provides a suction pipeline and a parallel compressor unit with the oil-gas separation function. Wherein, the suction pipeline with oil-gas separation function includes a three-way pipe and an air intake main pipe, a first air intake branch pipe, and a second air intake branch pipe respectively connected with the three-way pipe, and the three-way pipe is inside the An oil collection space is formed between the first air intake branch pipe and the second air intake branch pipe, and the communication position between the oil collection space and the first air intake branch pipe is higher than that between the oil collection space and the second air intake branch pipe. The connection position of the intake branch pipe, so that the separated oil enters the second intake branch pipe, and the separated gas enters the first intake branch pipe to realize the separation of oil and gas. The suction pipeline with oil-gas separation function provided by the present invention can realize oil-gas separation and avoid the reverse flow direction of oil and part of the air flow, and its application in compressor units can reduce the exhaust oil content of compressor units , to ensure the reliable operation of the compressor.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to an air suction pipeline and a parallel compressor unit with an oil-gas separation function. Background technique [0002] The parallel compressor unit includes two compressors, the suction chambers of the two compressors are connected through a tee, and the lower parts of the two compressors are connected through an oil balance pipe. When a single compressor in a parallel compressor train is running, the running compressor will suck most of the gas and oil. A small portion of the gas will enter the non-operating compressor, pass through the gap between the motor stator and the compressor housing of the non-operating compressor and the gap between the motor stator and the motor rotor, and enter the running compressor through the oil balance pipe bottom of the compressor. This part of the gas will go up through the gap between the motor stator and the compressor housing of th...
