6 FAQs about [Hydraulic accumulator maintenance]

How long does a hydraulic accumulator last?

All pressure vessels manufactured to these standards are considered to have a finite service life depending on the number of pressure cycles experienced during normal operation. The typical design life for a hydraulic accumulator is 12 years. In many jurisdictions, periodic inspection and recertification is required.

What does a hydraulic accumulator do?

A hydraulic accumulator is used for one of two purposes: to increase the system’s volume at a very high pace or to absorb stress. Its precharge determines the function it will carry out. If the accumulator is utilised to add volume to the system, its precharge must be slightly below the maximum system pressure to allow oil to enter.

Are accumulators a maintenance item?

They carry out numerous functions, which include energy storage and reserve, leakage and thermal compensation, shock absorption, and energy recovery. While accumulators present a number of advantages in hydraulic system operation and can provide many years of trouble-free service, they are a maintenance item.

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.

What gas should a hydraulic accumulator use?

Since hydraulic accumulators are pressure vessels, the installation, commissioning, disassembly, and maintenance should be performed by professionally trained and qualified personnel. Only use an inert gas like nitrogen for a pre-charging. Nitrogen that is 99.99 percent by volume is strongly recommended.

How often should a hydraulic accumulator be inspected?

Hydraulic accumulators should be carefully inspected visually at least once per year, more often in environments unfriendly to steel. Ensure there are no rust spots or cracks in the paint. Look for loose mounting points, worn rubber and any indication of movement during operation. Check all fittings for leaks.
