Problems solved by technology

[0003] Piston accumulator is one of them, but the problem often encountered in the use of piston accumulator is gas leakage. Gas leakage can be divided into external leakage of sealing structures such as end caps and charging valves, and leakage of piston sealing structures. Internal leakage, the more common problem is generally the internal leakage of the piston sealing structure. Due to the inertia of the piston and the friction of the seal, the sealing structure is damaged, resulting in the failure of the sealing structure, and at the same time, the piston is not sensitive enough.

Abstract

The invention relates to a piston type energy accumulator which comprises a tank body, an upper end cover arranged at the upper end of the tank body, a lower end cover arranged at the lower end of the tank body, and a piston arranged on the inner wall of the tank body. The piston is used for dividing the tank body into an independent air cavity and an independent oil cavity. An air inlet is formed in the upper end cover, and an oil inlet is formed in the lower end cover. A plurality of axial guiding ribs are evenly distributed on the inner wall of the tank body, and the piston is provided with guiding grooves adapting to the guiding ribs. The guiding grooves and the guiding ribs are matched to form a structure which can move vertically, and a ball layer is arranged in the guiding grooves and outside the piston. A plurality of balls are densely distributed in the ball layer, and a rubber layer is arranged outside the ball layer. The piston type energy accumulator has the advantages that the actions of the piston are sensitive, the sealing performance is good, and the piston type energy accumulator can be used for a long time.

Description

technical field [0001] The invention relates to the technical field of accumulators, in particular to piston accumulators. Background technique [0002] The existing accumulator is to inject incompressible high-pressure hydraulic oil into the accumulator for storage when the hydraulic system is idle, so that it can be supplied to the system at different times and needs, and can be used repeatedly. In this way, the utilization efficiency of the system can be fully utilized, and the energy consumption of the entire hydraulic system can be greatly reduced. In recent years, all parts of the world are vigorously pursuing alternative energy sources and advocating energy saving and carbon reduction. Accumulators are not only forward-looking sharp tools but also practical. [0003] Piston accumulator is one of them, but the problem often encountered in the use of piston accumulator is gas leakage. Gas leakage can be divided into external leakage of sealing structures such as end ca...
