    Hydraulic bladder accumulator is a type of hydraulic accumulator that use a flexible bladder to separate gas and hydraulic fluid, widely used in hydraulic systems in aerospace, automotive, marine industries and industrial applications.

    hydraulic accumulator applicationsTips: What is a bladder accumulator?

    A bladder accumulator is a type of hydraulic accumulator that uses a flexible bladder to store hydraulic fluid under pressure. The bladder is typically made of a durable, elastic material such as rubber or synthetic elastomers. It is housed inside a pressure vessel with an inlet and outlet for the hydraulic fluid.

    When hydraulic fluid is pumped into the bladder accumulator, it compresses the bladder and stores the hydraulic fluid under pressure. This stored energy can be used later to provide a burst of hydraulic power when needed.

    Bladder accumulators are commonly used in hydraulic systems where a large amount of energy is required for short periods of time. They are particularly useful in applications where a constant and steady hydraulic power output is not required, as the bladder accumulator can release the stored energy rapidly in short bursts.

    Bladder accumulators can store hydraulic fluid in volumes ranging from a few liters to several hundred liters, depending on the specific application requirements. They are commonly used in industrial applications such as hydraulic presses, lifts, cranes, and heavy machinery, as well as in mobile applications such as excavators, bulldozers, and dump trucks.
