Summary:

The noise problem in a multiple-piston hydraulic pump was investigated through computer simulation combining lumped and distributed parameter models (CFD). Analysis results have shown that the source of noise is the turbulence flow and pressure perturbation in the pump gallery caused by check valve flow interference. It was identified that this flow induced noise can be reduced by modifying the check valve characteristic and its flow profile without compromising pump performance
