High-speed heavy-duty linear reciprocating body operation energy storage device

Abstract

The invention relates to the technical field of hydraulic equipment, in particular to a high-speed heavy-duty linear reciprocating body operation energy storage device. The device comprises a tank body, an air storage tank and a high-pressure hydraulic cylinder, wherein an inner cavity of the tank body is separated into an air pressure chamber and a liquid storage chamber through an air pressure piston; the air storage tank is communicated with the air pressure chamber through a pipeline; the liquid storage chamber is provided with a liquid outlet and a liquid reflux inlet; the high-pressure hydraulic cylinder is provided with a liquid inlet and a hydraulic piston; and the air pressure piston is connected with the hydraulic piston through a piston rod. Because the area of the air pressurepiston is greater than that of the hydraulic piston, the air pressure piston has a large pressure area to push the liquid in the liquid storage chamber to have a high speed, the stored energy can be simultaneously and rapidly released together with the high-pressure hydraulic cylinder, the working efficiency is high, and the high-pressure hydraulic cylinders are pushed to exchange by a low-power small-flow pump, so that two liquid storage chambers alternately inhale liquid discharged by a working motion body cylinder in a reciprocating mode, and the working motion body can be pushed to move at a high speed. Therefore, the pressure and flow of the hydraulic cylinder of the working motion body are improved, the working operation speed is improved, and the electric energy is saved.

Description

Technical field: [0001] The invention relates to the technical field of hydraulic equipment, in particular to a high-speed heavy-load linear reciprocating body running energy storage device. Background technique: [0002] In some heavy machinery, it is often necessary to use a hydraulic system to drive a working moving body. The hydraulic system is a system that uses liquid as a working medium to transfer energy to achieve various tasks. As we all know, the hydraulic cylinder used in the hydraulic system is characterized by large force but slow action. If you want to speed up its speed, you must use a large-capacity oil pump, or use multiple groups of oil pumps in parallel to improve the hydraulic cylinder The oil supply flow rate, but this often causes excessive electricity consumption, high oil temperature, damage to the oil quality, and a substantial increase in cost. Summary of the invention: [0003] The purpose of the present invention is to provide a high-speed and heavy-d...
