Botswana horizontal hydraulic station accumulator

What types of accumulators are used in hydraulic systems?

Two designs of accumulators are widely used in hydraulic systems — piston and bladder accumulators, Figure 1. Piston accumulators include weight-loaded piston type, spring type, and hydropneumatic piston type. The weight-loaded type was the first used, but is very heavy for its capacity and much larger than modern piston and bladder types.

What are Hytec accumulators?

Accumulators from Hytec Fluid Technology (HFT) consist of only the highest quality manufactured by internationally well-renowned accumulator OEMs. Our range of hydraulic accumulators consists of Bosch Rexroth, Hydac and Olaer piston accumulators, diaphragm accumulators and bladder accumulators.

HFT has a hydraulic accumulator for your application, guaranteed: We stock 16 bladder accumulators, 7 piston accumulators, 6 diaphragm accumulators, hydraulic dampers and a range of accessories!

How does a piston type accumulator work?

In the piston type accumulator, the energy in the compressed gas exerts pressure against the piston separating the gas and hydraulic fluid. The piston in turn, forces the fluid from the cylinder into the system and to the location where useful work will be accomplished.

Which type of accumulator is most commonly used in industry?

Hydropneumatic piston accumulators are now the type most commonly used in industry. Energy storage — Hydraulic accumulators incorporate a gas in conjunction with a hydraulic fluid. The fluid has little dynamic power-storage qualities; typical hydraulic fluids can be reduced in volume by only about 1.7% under a pressure of 5000 psi.

How does a hydraulic accumulator work?

Changes in system pressure cause the piston to glide up and down along the shell, allowing fluid to enter or forcing it to be discharged from the accumulator body. The accumulator is empty, and neither gas nor hydraulic sides are pressurized. The accumulator is precharged. The hydraulic system is pressurized.
