Research on Vibration Control in a Reciprocating Compressor Piping System Using an Orifice Tube Structure

With the severe piping vibration caused by the gas pulsation of the reciprocating compressor, installing the orifice plate near the large container of the pipe system is an effective and simple solution for decreasing the gas pulsation in the field. In this paper, the fluid dynamics analysis proves that the improved orifice tube structure can better decrease the gas pulsation, and it is effective to reduce the piping vibration of a reciprocating compressor unit which is caused by the gas pulsation. The gas pulsation amplitude in the compressor pipeline system is decreased fundamentally by using the orifice tube, and the unit is in good running condition after the transformation, which effectively guarantees the long-term stable operation of the unit.
