- 1. It consists of a fixed vertical ram inside which is provided a central liquid passage of small diameter. This fixed cylinder ram is surrounded by a closely fitted brass brushes. Outermost layer is an inverted sliding cylinder having a circular projected collar on which loads are placed. Inlet and Outlet pumps.
- 2. The passage for liquid to enter and leave the unit are provided with the fixed ram which is connected to the inlet and outlet pipes. Pump is a hydraulic device used to convert the input mechanical energy into hydraulic energy. The liquid supplied from the pump enters the cylinder through the central vertical hole provided in the fixed ram.
- 3. This hydraulic energy causes the loaded cylinder to move upwards and this motion happens until it is balanced by the weight of the load. And once equibrilium is attained the energy is stored in this system of differential hydraulic accumulator and it acts a source of energy for various purposes like lifting machines etc. During the downward motion of the loaded ram the liquid accumulated is pushed to the exit pipe and this source of energy is used for the applications.
- 4. Energy storage device. Absorb pulsation. Cushions operational shocks. Pressure maintaining device. Dispenser.
- 5. Clamping device the hold the work piece with the devices like jaws vices. Mining machinery and equipment. Standby power source in industries. Automobile industry: Suspensions in vehicle. ABS Brakes. Power steering. Agricultural machinery and equipment. Forestry equipment. Surge reduction circuit.
- 6. The following are few parameters which are to be considered during selection of the differential hydraulic accumulator based on application purpose. Accumulator type. Accumulator volume. Nominal hydraulic system pressure.
- 7. Pre-charge pressure. Required flow rate. Fluid type. Output volume capacity. Response time.
