What are the causes of severe pressure drop and shortened service life in bladder-type accumulators?

What are the causes of severe pressure drop and shortened service life in bladder-type accumulators?

What are the causes of severe pressure drop and short service life in bladder-type accumulators? The structure of a bladder-type accumulator is quite simple, consisting mainly of an oil chamber surrounding the bladder and a gas chamber equipped with a gas‑tight seal. During operation, the hydraulic fluid must be connected to the hydraulic circuit; when the system pressure rises, the fluid flows into the accumulator, compressing the gas until the pressure in the system pipeline stabilizes.
