The hydraulic fluid reservoir holds excess hydraulic fluid to accommodate volume changes from: cylinder extension and contraction,Concentrator table temperature driven expansion and contraction, and leaks.Spiral separator The reservoir is also designed to aid in separation of air from the fluid and also work as a heat accumulator to cover losses in the system when peak power is used. Design engineers are always pressured to reduce the size of hydraulic reservoirs,Spiral separator while equipment operators always appreciate larger reservoirs.

Some designs include dynamic flow channels on the fluid's return path that allow for a smaller reservoir.Spiral separator

Accumulators are a common part of hydraulic machinery. Their function is to store energy by using pressurized gas.Spiral separator One type is a tube with a floating piston. On one side of the piston is a charge of pressurized gas,China spiral classifier and on the other side is the fluid. Bladders are used in other designs.China spiral classifier Reservoirs store a system's fluid.
