Embodiment Construction

[0021] A preferred embodiment of the present invention will be briefly described below in conjunction with the accompanying drawings.

[0022] Such as figure 1 Shown:

[0023] A hydraulic pump station, including a pump unit and an oil tank 1, the pump unit includes an oil pump 2 and a motor, the inlet of the oil pump 2 is connected to the oil tank 1, and the oil pump 2 adopts a six-piston swash plate axial plunger double oil Road pump; the outlet of the oil pump 2 is divided into two branches after the one-way valve 3, the first branch is connected to the inlet of an electromagnetic reversing valve 4, and an outlet of the electromagnetic reversing valve 4 is passed through the hydraulic control unit The output of the directional valve 5 and the superimposed one-way throttle valve 6 is used as the oil supply port, and the other outlet is output through the hydraulic control check valve 5 and the superimposed one-way throttle valve 6 as the oil return port. The oil tank 1 of t...

Abstract

The invention provides a hydraulic pump station which comprises a pump unit and an oil tank. The pump unit comprises an oil pump and a motor. An inlet of the oil pump is connected with the oil tank. The oil pump adopts a six-plunger-inclined-disc-type axial plunger two-oil-channel pump, and three low-pressure plunger rods and three high-pressure plunger rods which are arranged alternatively compensate with each other to achieve automatic pressure change and automatic oil return. An outlet of the oil pump is divided into two branches behind a one-way valve, and a plurality of oil outlet ports are formed. The hydraulic pump station has the advantage that a two-way oil channel is adopted, and reversing is conducted through a reversing valve. When a two-way action oil cylinder is used for a jack with a spring return stroke, the other way of the reversing valve can be closed, and two or four jacks or hydraulic devices can be driven simultaneously.

Description

technical field [0001] The invention relates to the technical field of hydraulic pumps, in particular to a hydraulic pump station. Background technique [0002] In the prior art, the hydraulic pump station has fewer oil outlets and is a one-way oil circuit, which cannot drive two or four jacks or hydraulic tools at the same time; or because of its functional requirements, its volume is large and its weight is relatively heavy , in the process of application, there will be certain limitations. Contents of the invention [0003] In view of the above problems, the problem to be solved by the present invention is to provide a hydraulic pump station with two-way oil passages. [0004] Technical scheme of the present invention is as follows: [0005] A hydraulic pump station, including a pump unit and an oil tank, the pump unit includes an oil pump and a motor, the inlet of the oil pump is connected to the oil tank, the oil pump is a double oil channel pump, and the outlet of ...
