Abstract
A full electric vane mounting angle adjuster for pumps comprises a motor and a speed reducer. Wherein, the motor rotates to transmit drive to a first drive part through the speed reducer with a large transmission ratio. A first drive part enables a second drive part to drive an angle adjusting rod to lift axially through a screw pair, thus realizing stepless vane mounting angle adjustment without pump shutdown. An axial working force generated by a hydraulic vane torque towards the angle adjusting rod is supported by a thrust bearing. Remote control and adjustment can be realized through a controller. The utility model brings simple and convenient operation.
