6 FAQs about [Hydraulic accumulator connection method]

How do you use a hydraulic accumulator?

• take proper safety precautions noted on the instructions. If an accumulator is already installed on a system, pump a small amount of system fluid (10% of accumulator capacity) into the accumulator, at low pressure. (Do not exceed 35 psi). Turn off all power to the system and fully release all hydraulic pressure from the accumulator.

How do hydro-pneumatic accumulators work?

Hydro-pneumatic accumulators use compressed gas to apply force to hydraulic fluid using different construction elements to separate the gas side from the fluid side. Bladders use a flexible closed membrane, diaphragms use a flexible open membrane and pistons use a moveable piston with a sealing system.

How do I install an accumulator?

For most systems, the installation process is a matter of placement, connection, and operation. Placement of the accumulator in the system is generally specified by the system designer. In these cases, the installer should take a reality check to make sure the selected location is feasible.

How do you precharge a hydraulic accumulator?

Correct precharging involves accurately filling the gas side of an accumulator with a dry, inert gas such as nitrogen, before admitting fluid to the hydraulic side. It is important to precharge an accumulator to the correct specified pressure. Precharge pressure determines the volume of fluid retained in the accumulator at minimum system pressure.

What factors should be considered when selecting a hydraulic accumulator?

The accumulator has discharged its design maximum volume of fluid back into the system. When selecting an accumulator for a particular application, both hydraulic system and accumulator performance criteria should be considered. To ensure long and satisfactory service life, the following factors should be taken into account:

What is a correct accumulator?

A correctly specified accumulator can: reduce shock effects in a system resulting from inertia or external mechanical forces maintain system pressure by compensating for pressure loss due to leakage provide a back-up supply of hydraulic energy to maintain a constant flow when system demand is greater than pump delivery.
