Gas Loaded Type Hydraulic Accumulators

{0 Comments}

These types of accumulators (frequently referred to as hydro-pneumatic accumulators) have been found to be more practically viable as compared with the weight and springloaded types. The gas-loaded type operates in accordance with Boyle’s law of gases, according to which the pressure of a gas is found to vary inversely with its volume for a …

Spring Loaded Type Hydraulic Accumulators

A spring-loaded accumulator is similar to the weight-loaded type except that the piston is preloaded with a spring. A typical cross-section of this type of accumulator has been illustrated in Figure 7.15. The spring is a source of energy, acting against the piston and forcing the fluid into the hydrauhc system. The pressure generated by …

Weight Loaded Type Hydraulic Accumulators

The weight-loaded type is historically the oldest type of accumulator. It consists of a vertical heavy wall steel cylinder, which incorporates a piston with packing to prevent leakage (Figure 7.14). A dead weight is attached to the top of the piston. The gravitational force of the dead weight provides the potential energy to the accumulator. …
