Abstract

The invention relates to a novel twin-triangular rotor hydraulic pump. The novel twin-triangular rotor hydraulic pump comprises a front rotor oil outlet check valve, a front rotor, a front rotor oil inlet check valve, a pump housing, a back rotor oil outlet check valve, a back rotor, a back rotor oil inlet check valve and an input shaft, wherein the front rotor oil outlet check valve is fixedly connected with the top end of the surface of the pump housing; the front rotor oil inlet check valve is fixedly connected with the bottom end of the surface of the pump housing; the back rotor oil outlet check valve is fixedly connected with the top end of the surface of the pump housing; the back rotor oil outlet check valve and the front rotor oil outlet check valve are positioned on the same axis; the back rotor oil inlet check valve and the front rotor oil inlet check valve are positioned on the same axis; the back rotor oil inlet check valve is fixedly connected with the bottom end of the surface of the pump housing; the input shaft runs through one side of the pump housing and is rotationally connected with the pump housing; the front rotor is rotationally connected with a front gear of the input shaft; the back rotor rotationally connected with a back gear of the input shaft. The novel twin-triangular rotor hydraulic pump has the main characteristics of high flow, high efficiency, small volume, simple structure, and smooth running without impact.

Description

technical field [0001] The invention relates to an industrial product, in particular to a novel double-connected triangular rotor hydraulic pump. Background technique [0002] At present, the pump is the most important component in the hydraulic system. Currently, there are mainly three types of gear pumps, vane pumps and plunger pumps that are widely used, but each has its own advantages and disadvantages. The advantages of gear pumps are simple structure and reliable operation, but low volumetric efficiency, high noise, and obvious flow pulsation; the advantages of vane pumps are large displacement, uniform flow, and low noise, but poor reliability and complex structure; plunger pumps The advantages are compact structure, convenient processing, small volume per unit power, but high cost, complex structure, and sensitive to oil pollution. Therefore need a kind of novel hydraulic pump on the market. Contents of the invention [0003] The present invention mainly aims at ...
