Abstract

The invention relates to a double-cylinder plunger pump which comprises a first cylinder body, a second cylinder body and a thrust plate which is respectively corresponding to the first cylinder body and the second cylinder body; the axis of the first cylinder body and the axis of the second cylinder body intersect outside the first cylinder body and the second cylinder body and form a first included angle, and an angle bisection plane of the first included angle is a second plane; the first cylinder body is provided with a first cylinder holes; the second cylinder body is provided with a second cylinder hole corresponding to the first cylinder hole; the crossing point of the central lines of the corresponding first cylinder hole and second cylinder hole is positioned on the second plane; the first cylinder body and the second cylinder body are connected in a transmission mode through a plunger assembly; the plunger assembly comprises two plungers which are slidingly inserted in the corresponding firs cylinder hole and second cylinder hole; and the adjacent ends of the two plungers extend out of the respective cylinder holes and are connected in a transmission mode through a connecting piece which is used for enabling the two plungers to stretch out or draw back in the respective cylinder holes in the rotation process of the two cylinder bodies. Through the double-cylinder plunger pump provided by the invention, the problems of low flow rate and low efficiency of the traditional axial plunger pump are solved.

Description

technical field [0001] The invention relates to a hydraulic drive device, in particular to a double-cylinder plunger pump. Background technique [0002] At present, there are three main types of hydraulic oil pumps on the market: gear type, vane type and plunger type. Generally speaking, the gear pump has good self-priming ability, strong anti-pollution ability, and simple structure, but the contact specific work of its meshing tooth surface is large; the vane pump has the advantages of long life, low noise, uniform flow rate and small volume, etc. It is sensitive to the pollution of the medium, and due to the influence of factors such as blade throwing force, suction speed and wear, its speed is limited and its sealing effect is poor; the plunger pump has been favored because of its compact structure, light weight and high working pressure. Wide range of applications. At present, the most widely used plunger pumps on the market are mainly inclined shaft type and swash pla...
