Product overview
Accumulator capsule, also known as the accumulator capsule, is an important part of the bladder accumulator, usually made of
rubber, with flexibility, used for storage of compressed inert gas. Generally speaking, the capsule is filled with nitrogen at a
certain pressure, and the outside of the capsule is filled with hydraulic oil. The capsule will deform as the hydraulic oil
squeezes it, thus compressing nitrogen to store energy, or releasing energy. The top of the accumulator generally uses a large
mouth structure, in order to facilitate the replacement of the capsule. The NXQ type accumulator capsule is in line with HG2331-92
standard and ASME standard. It has the advantages of oil resistance, acid and alkali resistance, flexure resistance, small
deformation and high strength, and can work normally in the range of -10-+70.
