Abstract

Purpose. Creation of a control system for the axial-piston variable pump with improved static and dynamic characteristics in different operation modes due to application of an improved pump flow regulator. Design/methodology/approach. The developed circuit of an axial-piston variable pump with a combined flow regulator provides static characteristic of the variable pump in the flow stabilization mode and static characteristic of a hyperbolic type in the constant power mode through the form of a profiled port of the regulator spool. To investigate the processes in the variable pump control system, a mathematical model was elaborated that includes refined, experimentally obtained dependencies of the pump swashplate resistance moment and flow rate through the profiled port of the spool. A prototype of the combined floe regulator was developed taking into account the results of its design parameters optimization. Originality/value. The prototype of the combined flow regulator with the profiled port of the spool provides improved static and dynamic characteristics of the axial-piston variable pump in the flow stabilization and constant power modes.
