Abstract
The invention discloses a digital pulse variable axial plunger pump which comprises a pump body, an oil distribution disk, a cylinder body, a plunger arranged in the cylinder body, a piston shoe arranged on the end part of the plunger, a set plate, a pump shell, a transmission shaft and a variable control device, wherein the cylinder body is arranged on the end part of the transmission shaft, and the end part of the transmission shaft is fixed on a central line of the set plate through a steel ball; and the variable control device comprises a variable head, a thrust plate, a variable shaft and an adjusting screw rod. The axial plunger pump is characterized by also comprising a transition body, wherein one end of the transition body is fixedly connected with a flange plate, while the other end is connected with a linear stepping motor; a spindle of the linear stepping motor is fixedly connected with one end of a connecting piece, while the other end of the connecting piece is connected with the adjusting screw rod; and the linear stepping motor is connected with an electronic inductor. The axial plunger pump has the advantages of high control sensitivity, high frequency response, no lag, good stability and high working efficiency.
