Pulsation suppression in a reciprocating compressor piping system using a two-tank element:

摘要: Gas pulsations excited by reciprocating compressors could introduce severe vibrations and noise in piping systems. When pulsating gas flows through the reducers, changes flow characteristics, such as velocity damping coefficient, will affect pressure pulsations. To circumvent these constraints, a two-tank element is introduced to control pulsation that still strong system with surge tank. Installing another tank form more flexible costs lower than replacing original larger one. In this work, theoretical model based on wave theory was proposed study transferring mechanism of pipeline element. By considering coefficient Mach number, distributions were predicted agreed three-dimensional fluid dynamics transient analysis. Three experiments conducted prove ...
