Abstract:

As is known，the hydraulic performance of a reciprocating pump is affected by its suction system configuration. in order to study how the suction system configuration affects the pump's hydraulic performance，this paper analyzes the working performances of the reciprocating pump with changeable suction system configuration，and the relation between suction performance and suction system configuration，thus determining the best suction system configuration. The experimental results show that the pump's hydraulic performances have much to do with other important phenomena，which were observed and analyzied during the experiment.

Key words: Reciprocating pump, Pump characteristic, Performance test
