To learn the following :
Pneumatic Circuits:-
- Actuate one double acting cylinder using AND gate (to and fro can be any actuation/return type) using single DCV .
- Simultaneously expand two double acting cylinders (retraction can be any) using air pilot valve.
- Make a circuit of retention switch using push button
- Expand single double acting cylinder using relay and retraction can be any way
- Actuate two double acting cylinders in which 2nd one should start expanded once the 1st one fully expanded and both should retract automatically after both cylinders got expanded.
Hydraulics Circuits:-
- Design a hydraulic circuit to control speed and direction of hydraulic
motor. The circuit may be operated using one pushbutton or retention
switch.
- Implement a Quick Return Mechanism for a double acting hydraulic
cylinder, where forward stroke velocity is slow and controllable (Like in
Shaper), and return stroke should be faster than forward stroke.
- Design a hydraulic circuit to actuate hydraulic motor after complete
expansion of double acting cylinder. (Such kinds of combination of
motions is required for carrying out tasks in industry. For e.g. drilling a
hole on work piece after securing it on fixture). (Hint: after complete
expansion, pressure builds up in piston side, use a 3-way pressure
regulator to direct the flow after the pressure reaches a certain limit. You
may decide the limit)
