The standard bladder accumulator consists of a "closed" rubber bladder inside a forged steel shell. A mechanically actuated valve closes when the fluid has been expelled, blocking off the fluid port, thereby enclosing the bladder within the shell. Where high discharge rates are required, a high flow model is available.

Piston accumulator working principle: Piston accumulators work on the principle of accumulating liquid by utilizing the compressibility of a gas (nitrogen). Piston accumulators consist of an oil part and a gas part with a piston acting as a gas-tight spacer. The air cavity is pre-filled with nitrogen, and the oil part is connected with the

2 The accumulator is installed in the hydraulic system and the fluid is increased to the maximum working system pressure, P 2. This is often called "charging" the accumulator. • At P 2, the gas volume in the diaphragm accumulator is V 2. • At this step the maximum amount of fluid possible for a particular system pressure

Hydraulic actuators come at the end of the process, where the hydraulic energy is converted back to mechanical energy. This can be done through using a hydraulic cylinder which converts hydraulic energy into linear motion and work, or a hydraulic motor which converts hydraulic energy into rotary motion and work.

The main task of the hydraulic accumulator is to accumulate fluid under pressure and return it when necessary. Since the accumulator contains a fluid under pressure, it is treated as a pressure tank and must therefore be sized for the maximum operating pres- sure according to test regulations in force in the country where it is instal- led.

Working principle of accumulator. . The accumulator is a hydraulic auxiliary designed to store the compressed liquid. The liquid is incompressible, and the accumulator uses the compressibility of the gas to achieve the purpose of storing the liquid. When the pressure rises, the oil enters the accumulator and the gas is compressed.
