Design and draw a circuit using the cascade system

Assignment Help Mechanical Engineering
Reference no: EM131070371

1) Design and draw a circuit using the cascade system to operate two cylinders (A and B) which, on the operation of a start valve, produces the sequence A - B + B - A+. The cylinders should park in the positions B - A + when the start switch is in the ‘off' position

2) Modify the circuit designed for question 1 to provide an emergency stop which will park both cylinders in the extended position (i.e. A + B +).

3) Modify the circuit designed for question 1 to provide a fail safe. The fail safe should:

(a) act in the event of a reduced pressure at inlet to the group selecting valve

(b) park the cylinders in the retracted position.
