Abstract

The operational process of a piston pump with dampeners which valves are replaced by hydraulic semiconductors is researched. The calculation model for the complex stream flow in the pump flow-part under harmonic motion of a piston is proposed. Dependences of flow characteristic and pump efficiency are derived. The influence of pump parameters on its characteristics is analyzed. It is found that an increase of the piston relative square and diodicity causes flow characteristic boost. Valveless pump efficiency mainly depends on diodicity, diodicity increase causes efficiency boost.
