The proposed controller includes a gas charged accumulator to replace the use of mechanical springs in the feedback path. which allows us to select pumps of lower hp than the maximum hp required titanium and composites! Hence we can categorize the accumulator in the following. If there is no loss of pre-charge at that time, it should be re-checked in 90 to 120 days and annually thereafter. Each type of accumulator has advantages and limitations that must be considered. Preferably, the low pressure accumulator contains a perforated metal member which limits compression of the bladder by hydraulic fluid beyond a fixed distance. 13.5 Accumulator Design Considerations. accumulators operate by the expansion and compression of nitrogen gas that is separated from hydraulic fluid by either rubber bladders or pistons.
