Abstract
The invention discloses a double-piston type energy accumulator. The energy accumulator comprises a cylindrical casing, a first energy accumulation chamber, pistons, piston rods, one-way valves, a second energy accumulation chamber and limiting bulges, wherein the cylindrical casing is divided into the first energy accumulation chamber and the second energy accumulation chamber by the aid of a separating plate, one piston rod is arranged in each of centers of the first energy accumulation chamber and the second energy accumulation chamber, one piston is arranged at one end of each piston rod, a channel is formed in each piston, one one-way valve is arranged at one end of each channel, and the limiting bulges are arranged at bottoms inside the first energy accumulation chamber and the second energy accumulation chamber. The energy accumulator comprises the two energy accumulation chambers, so that the energy accumulator can accumulate energy continuously in a gapless manner; meanwhile, the energy accumulator accumulates the energy by the aid of hydraulic components, so that the energy accumulation state can be relatively stable, and the energy accumulator is easy to control.
Description
Technical field
The present invention relates to accumulator technical field, be specially a kind of dual Piston accumulator.
Background technology
Accumulator is a kind of device stored and discharge oil liquid pressure energy in hydraulic system, it is divided into gravitational load formula, spring-loaded and gas loaded type by its mode difference storing energy, gas-loaded formula is divided into again non-isolated and isolated, the function of accumulator: if the executive component of hydraulic system be intermittent work and compared with the dead time working time short；If the executive component of hydraulic system movement velocity difference in a cycle of operation is bigger, for saving the power consumption of hydraulic system, accumulator can be set in systems as auxiliary power source, such system can adopt a lower-powered hydraulic pump, when executive component does not work or movement velocity is relatively low, accumulator stores all or part of energy of hydraulic pump；When executive component work or movement velocity higher time, accumulator release energy work alone or with hydraulic pump one executive component fuel feeding in the same direction.
At present, the structure of a kind of relatively simple spring-loaded accumulator includes shell, is placed in the spring of enclosure and for executing stressed ring baffle, the compression utilizing spring stores energy, the pressure produced depends on rigidity and the decrement of spring, but, its service life is relatively low, output energy time pressure can along with reduction, more unstable.
