Study on Pulsations of Reciprocating Compressor Piping Systems

Pressure pulsations in reciprocating pump piping systems Part 1: modelling

A distributed parameter model of pipeline transmission line behaviour is presented, based on a Galerkin method incorporating frequency-dependent friction. This is readily interfaced to an existing model of the pumping dynamics of a plunger pump to allow time-domain simulations of pipeline pressure pulsations in both suction and delivery lines. A new model for the pump inlet manifold is also pro...

Study on Influence of Certain System Parameters on Pressure Pulsations of Multistage Reciprocating Compressor System

Prediction of pressure pulsation magnitude and their harmonic components for a multistage reciprocating compressor, piping and reservoir system depends on the input design and operating parameters. In the present paper, the results of the theoretical study carried out to study the effect of such parameters on pressure pulsations and their harmonics have been presented. The effect of pipe diamet...

Fault Diagnosis of Reciprocating Compressor Using Pressure Pulsations

The major problems encountered in a reciprocating compressor are because of the valve failure .The other problem of leakage past the piston because of the worn out piston rings has also been placed in the reciprocating compressor. Pressure pulsations generated inside the piping of a reciprocating compressor may be taken as one of the tool for diagnosing the nature of fault inside the compressor...

Parametric Study of Hermetic Reciprocating Compressor

A numerical simulation of the thermal and fluid-dynamic behaviour of hermetic reciprocating compressors has been developed by solving the one-dimensional and transient governing equations of the flow (continuity, momentum and energy) in the whole compressor domain. The governing equations are discretized using an implicit control-volume formulation. A SIMPLE-like algorithm, extended to compress...
