Additionally, leaking and maintenance costs can both be reduced as accumulators mitigate system shock and thus promote longer service lives of parts. Coupled with improved performance, lower noise levels, reduced energy costs, and heightened flexibility in design, accumulators are very beneficial for many applications.

First on our list is the accumulator's pressure maintenance function in the hydraulic system. The fluctuating temperatures of liquid in the hydraulic system usually has a direct implication on the system's overall pressure. Hydraulic fluid leakage also results in pressure drop. This issue can be rectified by an accumulator.

G) Crack open nitrogen bottle valve and slowlyfill accumulator. Shut off when gauge indicates desired pre-charge. (H) Let the pre-charge set for 10 to 15 minutes. This will allow the gas temperature to stabilize. If the desired pre-charge is exceeded, close nitrogen bottle valve, then slowly open bleed valve (Figure 1).

What is a Hydraulic Accumulator and How Do They Work?

A hydraulic accumulator is classed as a pressure vessel which holds hydraulic fluid and a compressible gas. Usually, the piston or rubber bladder inside the accumulator is responsible for separating the oil from the gas. The volume of gas in a hydraulic accumulator is precharged to around 80/90% of the minimum system working pressure.
