Rubber Bladder

An accumulator bladder is a key component of a hydraulic bladder accumulator, which isa device used to store and release hydraulic energy in a fluid power system. The accumulator bladder is a flexible membrane that separates the hydraulic fluid and gas or nitrogen charge in a hydraulic accumulator. It enables the storage and release of hydraulic energy, contributing to the overall performance and efficiency of the hydraulic system.

The choice of bladder material depends on the specific application requirements, including the type of hydraulic fluid used, operating pressures, temperature range, and compatibility with other system components. Common bladder materials include elastomers such as nitrile rubber (NBR) or ethylene propylene diene monomer (EPDM).

        Accumulator bladders are designed to be durable, flexible, and resistant to hydraulic fluid and gas permeation. They undergo rigorous testing to ensure their integrity, performance, and long service life. Regular inspection and maintenance of the bladder are necessary to check for any signs of wear, damage, or leakage.
