Question
The circuit has been designed to crush a car body into bale using a 150 mm diameter
hydraulic cylinder. The hydraulic is to extend 2.50 m during a period of 10s. the time
between crushing strokes is 8 min. the following accumulator gas absolute pressures are
given:
P1 = Gas precharge pressure 90bar(abs), P2 = Gas charge pressure when pump is turned
on 200 bar(abs) = pressure relief value setting,P3 = Minimum pressure required to actuate
load 125 bar (abs).Calculate: (i) the required size of the accumulator
(ii) What are the pump hydraulic kW p
