How does a hydraulic accumulator work in a high pressure EH oil system?

The high pressure accumulator mainly balances the hydraulic pressure changes in the pipeline.Concrete analysis of specific examples: many of the oil motor system fast startup (steam turbine begins to spin, for example, two medium voltage regulator is open at the same time, or 2900 when the valve is switched, 6 high door open at the same time), ninghai wholesale capsule accumulator system pressure will drop rapidly, at this point, the oil pump is not reflected.

The accumulator is designed not only to be near the oil motor, but also to replenish the system more quickly than the pump.When the system oil pressure drops to 9.7mpa, the protection action will be stopped.

The importance of accumulators is important in high pressure EH systems.Because fluids are virtually incompressible and cannot store energy, hydraulic accumulators have.An accumulator used to store fluid using the compressibility of a gas (nitrogen) is essentially a chamber used to store pressurized fluid energy through the compressibility of the gas.When the system pressure rises, the fluid compresses the gas and flows into the accumulator, and the system pressure drops.

The compressed gas expands, forcing the fluid back into the hydraulic loop.Typical applications of accumulators: fluid storage, emergency energy, absorption pulse, pneumatic capsule accumulator wholesale surge control, noise attenuation, vehicle attenuation, volume compensation, pressure compensation, leakage compensation, thermal expansion absorption, mechanical balance, increased flow
