Double-acting hydraulic control system of supercharging device

Abstract

The invention discloses a double-acting hydraulic control system of a supercharging device. The double-acting hydraulic control system comprises a hydraulic pump, an oil storage tank, a control valve, a first hydraulic cylinder, a second hydraulic cylinder and an oil make-up tank, wherein a piston rod of the first hydraulic cylinder and a piston rod of the second hydraulic cylinder are in butt joint. A first work port of the control valve communicates with a rodless cavity of the first hydraulic cylinder, a second work port of the control valve communicates with a rodless cavity of the second hydraulic cylinder, a fourth work port of the control valve communicates with the oil storage tank, and a third work port of the control valve communicates with an oil outlet of the hydraulic pump. A first one-way valve, a second one-way valve, a third one-way valve and a fourth one-way valve are connected between a rod cavity of the first hydraulic cylinder and a rod cavity of the second hydraulic cylinder in parallel and are mounted symmetrically, and the oil make-up tank is arranged at the position, between the second one-way valve and the third one-way valve, of a pipeline. The double-acting hydraulic control system has the following beneficial effects that design is reasonable, practicality and convenience are achieved, equipment input is reduced, running energy consumption is low, the mechanic-electronic-hydraulic integrated design is adopted, and the intelligent degree is high.

Description

technical field [0001] The invention belongs to the field of hydraulic technology, and relates to a hydraulic system, in particular to a double-acting hydraulic control system of a supercharging device. Background technique [0002] Hydraulic transmission and control use liquid (oil, high water-based hydraulic oil, synthetic liquid) as the medium to realize the output of various mechanical quantities (force, displacement or speed, etc.). Compared with pure mechanical transmission, electric transmission and pneumatic transmission, it has the characteristics of large transmission power, small structure and fast response, so it is widely used in various mechanical equipment and precise automatic control systems. In the hydraulic system, when a part or a certain actuator needs high pressure, a high-pressure oil pump needs to be installed separately in the system. However, using a high-pressure oil pump has problems such as high price of the oil pump itself and high energy consum...

AI Technical Summary

Problems solved by technology

In the hydraulic system, when a part or a certain actuator needs high pressure, a high-pressure oil pump needs to be installed separately in the system, but the use of a high-pressure oil pump has the problems of high price of the oil pump itself and high energy consumption during use.
