(1) characteristics of compliant media

Piston accumulator on the oil cleanliness requirements are higher, if not enough to ensure the oil clean, good choice of air accumulator and gap accumulator.Water as the medium of the system, should choose the air bag accumulator or gap accumulator, because the water easy to take care of more impurities, poor smoothness, zhenhai capsule accumulator company and will erode the piston coating.

(2) suitable for echo

When required to echo <25ms use occasions, should use air bag or gap accumulator.If you want an echo, it's greater than or equal to 25, right?In the case of ms, air bag, gap or piston accumulator can be used.

(3) the inflation pressure is suitable

According to the divergence of energy storage in the hydraulic system, an accumulator suitable for charging pressure should be selected.When the accumulator is used as the receiving system to receive the pulse, the charging pressure is usually 60% of the uniform value of the event pressure.When it is used to receive the pressure blow from the system, the inflatable pressure should not be less than the general pressure.When it is used to help the power source, the aeration pressure is generally used at 80% ~ 90% of the low event pressure, and should span the high event pressure 25%.

(4) reincarnation frequency is suitable

The system with high reincarnation frequency should choose airbag type or barrier type accumulator, ninghai hydraulic accumulator wholesale, and should not choose piston type accumulator, because too high reincarnation frequency will cause unstable piston movement, piston seal damage.

(5) comply with functional requirements

If the accumulator is used to receive the blow and eliminate the pulse, it is better to choose the air bag accumulator and the gap accumulator.The piston accumulator is not suitable for receiving and eliminating pulse because of its poor activity.

(6) suitable for use occasions

The effectiveness of the air bag accumulator is the brake effective, beilun capsule accumulator company piston accumulator effective is gradually effective, in accordance with the use of different occasions to choose different situation of the accumulator.The steering and braking system of engineering machine should be equipped with piston accumulator instead of air bag accumulator, because if the air bag accumulator takes effect when braking, severe disturbance will be formed.
