Abstract

Reciprocating pumps with self-acting valves are commonly used for fluids with poor lubrication properties, high contamination levels or corrosive properties. A study has been made of the dynamic performance of these pumps, with particular regard to the self-acting valve characteristics. Using computer simulation, the effects of changes in the spring forces on the self-acting valves were investigated for a commercially available pump. The simulations predicted that modifications to spring forces could result in considerable improvements in performance, with increased volumetric efficiency and reduced valve impact velocity and flow ripple. These improvements were borne out experimentally. Vibration and air-borne noise were also greatly reduced. Results are presented of the measured and simulated valve motion and velocity, flow ripple and overall volumetric efficiency. Measured vibration and sound power level results are also presented and discussed. Correlation between measured and simulated results is shown to be good
