Hydraulic Accumulators: What Are They and Why Do We Need

A hydraulic accumulator located within a fluid system. Some hydraulic systems work in hazardous remote locations, which might get very hot, and the process of pressurizing hydraulic fluid also raises the temperature of the fluid. If an internal inspection is required or valves need to be replaced, the pre-charge gas will need to be

Hydraulic Piston Accumulators

Using appropriate valve in the hydraulic system, discharge all oil from accumulator and allow piston to bottom against hydraulic end cap. For accumulators rated for 3000 PSI or less, with cored gas valve, use gauging assembly as shown in Figure 2 (Part #085122XX00). For accumulators rated over 3000 PSI

How often should a hydraulic accumulator be inspected?

Diaphragm accumulators usually can be mounted in any position. 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.

What is a hydraulic accumulator used for?

A hydraulic accumulator is used for one of two purposes: either to add volume to the system at a very fast rate or to absorb shock. Which function it will perform depends upon its pre-charge. If the accumulator is to be used to add volume to the system, its pre-charge must be somewhat below the maximum system pressure so oil can enter it.

How an accumulator works | HYDAC

In years gone by this was achieved using a deadweight. However, spring-type accumulators or hydro-pneumatic type accumulators are still used in modern hydraulic applications. Hydro-pneumatic accumulators, which use hydraulic fluid to compress nitrogen gas and hence the name hydro-pneumatic, are the predominant accumulator type.

How to Ensure the Safe Operation of a Hydraulic Accumulator

For example, the correct gas pre-charge pressure must be maintained for proper functioning and optimum service life. And periodic inspection, testing and certification can be required by law, because hydraulic accumulators are pressure vessels. To get a proper prospective on this issue, a hydraulic accumulator must be compared with a gas cylinder.
