Oxygen is a transparent, odourless, and tasteless gas that comprises approximately 21% by volume of the earth''s atmosphere. Liquid oxygen is a clear liquid with a pale blue colour. Oxygen by itself is not flammable; however, the presence of oxygen or another oxidiser is necessary to support combustion.

A hydraulic accumulator is a pressure storage reservoir in which an incompressible hydraulic fluid is held under pressure that is applied by an external source of mechanical energy. The external source can be an engine, a spring, a raised weight, or a compressed gas. [note 1] An accumulator enables a hydraulic system to cope with extremes of

The analysis of the criteria that identify the energy component of a pumped storage facility must firstly allow defining the energy requirements that the pumping station itself must cover. Based on these energy requirements, two fundamental criteria emerge in the hierarchy of all those involved: the volume of water stored and the height that the

What is Pumped Storage Hydropower? Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine. The system also requires power as it pumps water back into

A hydraulic accumulator is a pressure storage reservoir in which an incompressible hydraulic fluid is held under pressure that is applied by an external source of mechanical energy. The external source can be an engine, a spring, a raised weight, or a compressed gas. 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

Reservoirs serve three purposes in the hydraulic system: They store the oil until the system requires it. They help provide for the cooling of the oil. They provide a place for contaminates to "settle out" of the oil. When selcting a tank reservoir, style/shape, material, capacity, placement, venting and porting are important considerations.
