A forced return plate distribution plunger type water pump

Abstract

The invention belongs to the field of volumetric hydraulic pumps and discloses a forced return disc flow distribution plunger type water pump which comprises a pump main body, a rotation unit, a flow distribution disc and a return mechanism; the pump main body is composed of a shell, a rear end cover, a front end cover and a slanting disc; the flow distribution disc is arranged in the pump main body, is fixedly installed on the front end cover and is provided with a waist-shaped groove and a through groove; the rotation unit is composed of a transmission shaft, a cylinder body, a plunger sliding shoe component, a main bearing, a floating disc, a spring seat and center springs; the return mechanism is composed of a return disc, a plurality of return springs, a wedged sleeve and an anti-rotation pin; each return spring is installed in a spring hole of a limiting ring; one end of each return spring is abutted to the inner wall of the limiting ring; and the other end of each return spring tightly presses the return disc through the wedged sleeve. The return mechanism provided by the invention integrates spring return and fixed gap limiting force return, so that the reliability of the return mechanism is improved, and the forced return disc flow distribution plunger type water pump is suitable for places with high requirements on the reliability of the water pump.

Description
