Eaton’s high-pressure, maintenance-free accumulators and reservoirs are designed to handle 5,000-psi operating pressures and perform reliably for 25 years or longer (typical MTBF

Pre-charge Maintenance Interval It is recommended to check pre-charge pressure after 1 week of commissioning and then after 3 months into operation. Thereafter, depending on the measured loss of pressure and performance, this can be scheduled from 3-6 months or even longer.

Hydraulic System Efficiency: Why Hydraulic Accumulator Maintenance Is Essential The purpose of hydraulic accumulators in a hydraulic system is to store fluid 

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.

Valcor Engineering Corporation has been a leading manufacturer of Hydraulic Aircraft Accumulators for Aircrafts, Helicopters, and Ground Vehicles for over 20 years. Valcor has demonstrated technical excellence by fully qualifying the first Maintenance Free Accumulators (MFAs) in the world for aircraft applications.

Apex Hydraulics offers you our FREE 'Strip and Quote Service' which includes: A complete strip down of your accumulator A comprehensive assessment and full diagnosis A speedy assessment to reduce critical downtime Sourcing of all spares required to complete the repair Providing you with a fully itemised quotation before any work commences.

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).

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.

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.
