Replacement of energy storage tank of fan hydraulic station

What is the state-of-the-art in the storage of mechanical energy for hydraulic systems?

This review will consider the state-of-the art in the storage of mechanical energy for hydraulic systems. It will begin by considering the traditional energy storage device, the hydro-pneumatic accumulator. Recent advances in the design of the hydraulic accumulator, as well as proposed novel architectures will be discussed.

What is the function of a hydraulic tank?

The primary function of any tank is the storage of substances or fluids. In our case, the tank must retain the total quantity of hydraulic oil, which is located in the hydraulic system. In addition the hydraulic tank should compensate for oil level oscillation due to temperature changes or possible leakage from the system.

How can a gravity hydraulic energy storage system be improved?

For a gravity hydraulic energy storage system, the energy storage density is low and can be improved using CAES technology . As shown in Fig. 25, Berrada et al. introduced CAES equipment into a gravity hydraulic energy storage system and proposed a GCAHPTS system.

How to design a hydraulic tank?

When designing the hydraulic tank, a designer should properly form the tank in order to increase the size of the area through which heat is emitted - thus providing better natural cooling (cooling ribs). One of the long-term risks of the hydraulic system is the formation of air bubbles, which can be detected by the noisy operation of components.

Why should a hydraulic tank compensate for oil level oscillation?

In addition the hydraulic tank should compensate for oil level oscillation due to temperature changes or possible leakage from the system. As a result of losses arising from the transformation of energy in the hydraulic components, the temperature of the hydraulic fluid rises when passing through the system.

How hydraulic tank design compared with standard industrial tank design?

Several variations of new hydraulic tank designs are compared with standard industrial tank. Furthermore, to achieve steady flow through the entire reservoir and reduce the phenomenon of oil swirling, newly-developed diffuser is used. Consequently a full scale hydraulic power unit was built according to obtained results.
