Hydraulic accumulator disassembly method

How to remove accumulator from hydraulic system?

Remove accumulator from hydraulic system. Threaded holes in hydraulic cap may be used as a means of attach-ment for lifting, or use a sling around the body. Once the gas valve is removed - lay the accumulator horizontal and hold down with a strap wrench or in a vise.

How should a hydraulic accumulator be positioned?

Insure the hydraulic fluid is compatible with the accumulator seals/elastomers. The accumulator should be positioned as near as practical to the source of shock/pulsation, or potential energy need. Porting/piping should be matched as closely as possible to insure free flow of hydraulic fluid in and out of the application system.

How do you reassemble a piston accumulator?

Coat all internal parts with clean hydraulic fluid before reassembly. It is highly recommended to use a piston starting sleeve for reassembly of piston accumulators. Call the factory for price and delivery. Starting sleeve dimensions are shown below. Insert the piston in the starting sleeve with the dished side of the piston toward the gas end.

How should a hydraulic accumulator port/piping be matched?

Porting/piping should be matched as closely as possible to insure free flow of hydraulic fluid in and out of the application system. Insure the porting/piping is appropriate for the MAWP of the system. Vertical orientation of accumulator with fluid port down is preferred.

How do you mount a hydraulic accumulator?

Keep the hydraulic port covered to keep out foreignmaterial until ready to make the hydraulic connections. The accumulator can be mounted in any orientation. However, it should be rigidly mounted using any combination of the mounting holes provided at the hydraulic cap or proper clamps.

How to mount a HYDAC piston accumulator?

In accordance with the recommendations of the HYDAC brochure “Mounting Components”, HYDAC piston accumulators must be mounted vibration free using clamps and base brackets. Note: Mounting elements must never be welded to the piston accumulator. 4. Connection The connection of the accumulator to the system must be stress free and torque free.
