【Abstract】 Oriented to the power distribution and control problems of a new type of variable displacement piston pump featuring high pressure and low noise,a load sensing element and a control system are developed and its constant flowrate characteristic is theoretically analyzed and tested.The effects of operational parameters and constructional parameters on constant flow rate accuracy,regulation range, flow stability and step response are investigated. Satisfactory consistency of results between theoretical analysis and experiment are obtained.更多还原
