In this article, I will be explaining the following experiment conducted in Fluidsim for the Instrumentation lab or Fluidsim lab.
Experiment – A double-acting cylinder should extend on pressing a push-button “A” and retract automatically after a delay.
If you haven’t read the previous experiments it is highly suggested to go through them first, they can be accessed from the following links –
Experiment Schematic :
Refer to the previous Experiment and associate the operation of Mechanically Operated Valves C and D to the positions L1 and L2 of Double Acting Cylinder.
When Push Button A is pressed, the cylinder moves forward.
Before the cylinder automatically retracts there is a delay, the amount of delay can be changed by changing the opening level of the One Way Flow Control Valve in the Time Delay Valve Arrangement.
Double click on the Time Delay Valve arrangement to change the opening level.
To observe the delay you will need to view the simulation in slow motion-
1. Go to Options > Simulation.
2. The Simulation Speed is by default on ‘Maintain Real-Time‘ , change it to ‘Slow-motion Factor‘ and edit the factor, keep it 10 in this case. Click ‘OK‘
