Description
Technical field
The present invention relates to accumulator technical field, specially a kind of dual Piston accumulator.
Background technology
Accumulator is the device of a kind of storage and release oil liquid pressure energy in hydraulic system, in the way of it stores energy
Difference is divided into gravitational load formula, spring-loaded and gas loaded type, and gas-loaded formula is divided into non-isolated and isolated, storage again
The function of energy device：If the executive component of hydraulic system is intermittent work and the working time is short compared with the dead time；If hydraulic pressure
The executive component of system movement velocity difference in a working cycles is larger, can be to save the power consumption of hydraulic system
Accumulator is set to use a lower-powered hydraulic pump as auxiliary power source, such system, work as executive component in system
Do not work or when movement velocity is relatively low, accumulator stores all or part of energy of hydraulic pump；When executive component works or moves
When speed is higher, accumulator release energy autonomous working or with the executive component fuel feeding in the same direction of hydraulic pump one.
At present, a kind of structure of relatively simple spring-loaded accumulator includes shell, the bullet of placement inside the housing
Spring and for applying stressed ring baffle, utilizes the compression storage energy of spring, and caused pressure depends on the rigidity of spring
And decrement, however, its service life is relatively low, pressure can be more unstable with reduction when exporting energy.
