2. Hydraulic accumulator
• The hydraulic accumulator is device used for
storing the energy of a liquid in the form of
pressure energy .
• This energy may be supplied for any sudden
requirement .
• Use energy when lift or crane is moving
upward .
4. # Capacity is the maximum amount of hydraulic
energy stored in accumulator .
A = area of sliding ram
L = stroke or lift of ram
p = water pressure supplied by pump
W = weight placed on the ram + weight of ram
W = p*A
Work done in lifting the ram =W*L
= p*A*L
