[note 1] An accumulator enables a hydraulic system to cope with extremes of demand using a less powerful pump, to respond more quickly to a temporary demand, and to smooth out pulsations. It is a type of energy storage device. Compressed gas accumulators, also called hydro-pneumatic accumulators, are by far the most common type.
A simple control system for a water well. Referring to the figure on the left, a submersible water pump is installed in a well.The pressure switch turns the water pump on when it senses a pressure that is less than P lo and turns it off when it senses a pressure greater than P hi.
The Dock Tower continued to provide water for hydraulic working until 1892 when the erection of the hydraulic accumulator tower on the opposite pier approximately 200 feet (61 m) to the North West of the Dock Tower took over - water in this structure was pressurised by a 300-tonne weight. Present dock and lock machinery are powered by electric ...
The hydraulic station used Otto 'Silent' type gas engines, and had two accumulators, with an 18-inch (460 mm) diameter piston, a stroke of 20 feet (6.1 m) and each loaded with a 93-tonne weight. The gas engines were started by a small hydraulic engine, which used the hydraulic energy stored in the accumulators, and all equipment was supplied by ...

Hydropneumatic refers to the pneumatic (gas) and hydraulic (water) components needed for operation of the devices. Hydropneumatic accumulators or pulsation dampeners are devices which prevent, but do not absorb, alleviate, arrest, attenuate, or suppress a shock that already exists, meaning that these devices prevent the creation of a shock wave ...

These accumulators are divided into two compartments by a movable piston, one side filled with hydraulic fluid and the other with nitrogen gas. The nitrogen is held in large tanks directly beneath the actual accumulator. As the hydraulic fluid fills the accumulators, it pushes on the pistons, compressing the nitrogen.
