Abstract

The invention relates to a novel duplex triangle rotor hydraulic pump which comprises a front rotor oil outlet one-way valve, a front rotor, a front rotor oil inlet one-way valve, a pump shell, a rear rotor oil outlet one-way valve, a rear pump, a rear rotor oil inlet one-way valve and an input shaft, wherein the front rotor oil outlet one-way valve is fixedly connected with the top of the surface of the pump shell; the front rotor oil inlet one-way valve is fixedly connected with the bottom end of the surface of the pump shell; the rear rotor oil outlet one-way valve is fixedly connected with the top of the surface of the pump shell; the rear rotor oil outlet one-way valve and the front rotor oil outlet one-way valve are arranged on the same axis; the rear rotor oil inlet one-way valve and the front rotor oil inlet one-way valve are positioned on the same axis. The duplex triangle rotor hydraulic pump is designed by changing the structure based on a rotor engine; the aim of reducing vibration is achieved in a way of staggering phase angles of similar straight engines; the novel duplex triangle rotor hydraulic pump has the main characteristics of high flow rate, high efficiency, small volume, simple structure and no impact, and is simple to operate.

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 ...
