A high-efficiency energy storage supercharger

Abstract

The invention discloses a high-efficiency energy-accumulation pressure booster which comprises at least one energy-accumulation unit, wherein the energy-accumulation unit comprises an energy-accumulation cylinder and a plurality of gas tanks. The high-efficiency energy-accumulation pressure booster is characterized in that the energy-accumulation cylinder is divided into two cavities which are independent from each other through a partition, and a piston component is arranged in the cylinder body; the piston component comprises a first piston, a second piston and a connecting rod; the first cavity is divided into a first air chamber and a first hydraulic storage chamber through the first piston; a first oil inlet and a first oil outlet are formed in the first hydraulic storage chamber; the second cavity is divided into a second air chamber and a second hydraulic storage chamber through the second piston; a second oil inlet and a second oil outlet are formed in the second hydraulic storage chamber; the first oil outlet is in control connection with an oil return tank or a hydraulic cylinder of a hydraulic machine through a first electric-control valve; the second oil outlet is in control connection with the hydraulic cylinder of the hydraulic machine through a second electric-control valve. By adopting the high-efficiency energy-accumulation pressure booster, initial pressure is reduced, an output oil pressure multiplicative effect can be achieved, danger is reduced, and equipment can be relatively conveniently maintained.

Description

technical field [0001] The present invention relates to hydraulic machinery, in particular to an energy storage supercharger, which can be connected in series to hydraulic drive systems of hydraulic machinery such as hydraulic presses, quick forging machines, pile drivers, etc., and can also be used in engine systems of vehicles and ships. Among them, it is used for energy storage and boosting to increase the action speed of the hydraulic cylinder. Background technique [0002] Hydraulic machinery is a machine that uses liquid as the working medium to transfer energy to realize various processes. It can be used not only for forging and forming, but also for straightening, pressing, packaging, briquetting and pressing, etc. Therefore, the hydroforming process is widely used in industries such as automobiles, aviation, aerospace and pipelines. [0003] As we all know, the characteristic of hydraulic machinery is that it produces a large force, but the speed of continuous work...
