Hydraulic accumulator is a mechanical device used in hydraulic applications. It works as an intermediate device between supply lines of hydraulic fluid from pump to required machines like hydraulic lift, hydraulic press, hydraulic cranes etc. It temporarily stores the pressurized hydraulic fluid when operating machine is at ideal condition.

In operation, the hydraulic pump raises system pressure and forces fluid to enter the accumulator. (Valves control oil flow in and out.) The piston or bladder moves and compresses the gas volume because fluid pressure exceeds the precharge pressure. This is the source of stored energy. Movement stops when system and gas pressures are balanced.

To operate this accumulator first we have to fully precharge the gas into the gas bag. The position of the gas bag after fully precharging the gas (This gas is generally Nitrogen gas or any inert gas) is shown Figure 2. When we fill the gas in the bag through port (B), the gas bag fully expands. During this step oil is under normal pressure.

The energy must be released or isolated before any work is done on an accumulator or on components that may be connected to an accumulator. When hydraulic pressure is relieved, there is still stored energy in the gas. This must also be relieved or isolated. Accumulators are preloaded so that there will be a minimum pressure for any available fluid.

They work well as long as there are minor load swings in the system. Flooded Systems. Flooded systems transfer heat more efficiently than a TXV system. This is due to the use of more wetted evaporator surface. The overfeed system ensures that a constant liquid level is maintained in the accumulator (sometimes referred to as a low-pressure
