Control system for hydraulic energy intelligent storage and precise transfer device

Abstract

The invention discloses a control system for a hydraulic energy intelligent storage and precise transfer device. A main accumulator is connected with a gas interface of a gas cavity pressure regulatorthrough a gas connecting pipe; a high-speed gas switching valve is arranged on the gas connecting pipe; a liquid interface of the main accumulator communicates with a three-position four-way solenoidvalve through an oil connecting pipe; the gas cavity pressure regulator is connected with a high-speed liquid switching valve through an oil connecting pipe, and the high-speed liquid switching valveis further connected with the three-position four-way solenoid valve; and the piston displacement of the main accumulator (12) and a speed signal are transmitted to a controller (6) through a displacement sensor (8), and meanwhile the controller (6) is connected with the high-speed gas switching valve (2), the high-speed liquid switching valve (4) and the three-position four-way solenoid valve (5) through signals. The problem that a traditional accumulator is uncontrollable is solved, and the energy consumption of a hydraulic system is reduced; and the energy storage capacity of the accumulator is regulated, so that the control system is applicable for different working conditions.

Description

technical field [0001] The invention relates to a hydraulic energy storage device, in particular to a hydraulic energy intelligent storage and precise transmission device control system. By detecting the piston displacement and piston speed of the energy storage device, the energy storage capacity and output capacity of the accumulator can be adjusted, which can be used in various controllable hydraulic energy storage devices, such as hydraulic machines, fine blanking machine tools, etc. Background technique [0002] The traditional hydraulic system can be divided into two categories: hydraulic transmission system and hydraulic control system. The main function of the hydraulic transmission system is to transmit power and motion, while the hydraulic control system must make the output of the hydraulic system meet specific performance requirements. The biggest problem facing the current hydraulic system is the problem of energy utilization. Due to the particularity of the hyd...
