technical field

The invention relates to the technical field of compressor buffering, in particular to a novel compressor buffering tank.

Background technique

Reciprocating compressors are widely used in natural gas, petroleum and chemical industries. The working characteristics of reciprocating compressors are that the air flow between suction and exhaust is intermittent and periodic. The fluid parameters in the tube change periodically with position and time, such as pressure, velocity, and density, which is the so-called airflow pulsation. When the airflow pulsating fluid is transported along the pipeline, it encounters components such as elbows, reducers, branch pipes, valves, blind plates, etc., which will generate excitation force that changes periodically over time. produce mechanical vibrations. The source of pulsation is the compressor cylinders of all stages arranged in the compressor. Some solutions in the prior art generally adopt the increase of pipeline support to achieve the purpose of preventing obvious vibration of the pipeline, which cannot control the airflow pulsation well, and ignores the influence of airflow pulsation on the air valve, pipeline, etc. of the compressor cylinder. The reliability and economy of the compressor cylinder are reduced; although some compressor cylinders are equipped with buffer tanks, if the volume is too small, the effect will not be achieved. to the effect, and the economic effect is poor.
