Analysis of hydraulic surge in hydraulic-drive reciprocating pump

The double cylinder double acting hydraulic drive reciprocating pump is introduced, in addition,the analysis and computation of hydraulic surge in feed oil loop and return oil loop are carried out on the basis of experiment. The key reasons of hydraulic surge produced in feed oil loop and return oil loop of hydraulic drive reciprocating pump and its effects on the discharge and overall performance of reciprocating pump are presented, which has some reference values for further study and design of hydraulic drive pump in future.
