Technical Field

The invention relates to a buffer tank device of a compressor, and belongs to the technical field of gas buffering and vibration control of compressors.

Background

The reciprocating compressor is used as gas supercharging equipment, is widely applied to the field of shale gas exploitation and transportation due to the advantages of large compression ratio, wide pressure application range, high efficiency and the like, and causes the gas at the gas inlet and outlet of the cylinder to be in a pulsating state, namely the pressure and the speed to be in periodic change due to the intermittent gas suction and discharge characteristics of the compressor. When the pulsating airflow flows through the non-constant section pipeline, an exciting force is generated to trigger forced vibration of the pipeline. The severe vibration of the pipeline is easy to cause the failure of key connection parts, pipe clamps and the like of the pipeline, and safety accidents are caused.

At present, the core of pipeline vibration control is to suppress airflow pulsation in a pipeline, the conventional method for suppressing the airflow pulsation is to adjust the volume of a buffer tank and add a pore plate in the buffer tank, and the common method for structural vibration control is to add a support at a position with larger vibration.
