Bladder A-25/31.5-L-EH-S supplied by Donfang yoyik


The accumulator bladder is an important part of the bladder-type accumulator. It is usually made of rubber and has flexibility for storing compressed inert gas. Generally speaking, a certain pressure of nitrogen is injected into the capsule, and hydraulic oil is filled outside the capsule. The capsule deforms as the hydraulic oil is squeezed, thereby compressing the nitrogen to store energy, otherwise it releases energy. The top of the accumulator generally uses a large-mouth structure to facilitate the replacement of the capsule


Capsule medium:

Inside the capsule: nitrogen

Outside the capsule: hydraulic oil, mineral oil, fire-resistant fuel, water, emulsion, fuel, etc.


Capsule capacity: 0.4-160L

Capsule length: 74-2150mm

Outer diameter of accumulator (mm)

Capsule code: NBR IIR CR FPM


Working principle:

The accumulator capsule divides the accumulator into two chambers, gas and liquid. The capsule is filled with nitrogen. The capsule and the shell form a chamber filled with hydraulic oil. After adding the one-way valve outlet, the volume of gas in the capsule increases with the pressure. Reduce, thereby absorbing shock hydraulic energy, reducing or eliminating system pressure shock.
