Title: Trainer Lab #9: Actuator Speed, Resistance, and Flow
Course: Fluid Power Pneumatics (Sandbox) > Section: Module 8: Principle of Actuator Speed - 1 Hour

Introduction

Now that you have read up on actuator speed, resistance, and flow, you will change the pressure using the following schematic. The following video will explain how to set up the lab.

Lab Instructions

1. Wear safety glasses.
2. Shut off the orange shutoff valve before you start hooking up any components.
3. Make sure that 2 of the 3 ports on the silver manifold are plugged.
4. Take a hose from the silver manifold and run it to the "P" port on the Manually Operated Valve.
5. Take a 8" hose (approximate length) and run it from the "A" port on the Manually Operated Valve to the inline pressure gauge (put the hose reducers in the gauge), then take an 8" hose (approximate length) and run it to the rod side of the Large Double-Acting Cylinder.
6. Take an 8" hose (approximate length) and run it from the "B" port on the Manually Operated Valve to the inline pressure gauge and then run it to the non-rod side of the Large Double-Acting Cylinder. (Reference video for further explanation.)
7. Push the Manually Operated Valve to the left or to the "B" side of the Manually Operated Valve.
8. Video yourself doing steps 9-11.
9. Turn on the orange shutoff valve and set the "FR" unit to 60 psi. Show the pressures on the "FR" pressure gauge and the rod side pressure gauge. They both should be reading the same.
10. Shift the Manually Operated Valve to the right side or to the "A" port. Watch the gauges.
11. Shift the Manually Operated Valve so that the cylinder is completely retracted.
12. Turn the "FR" unit so that it shows no pressure. Slowly turn up the pressure so that the cylinder extends slowly.
13. Retract the cylinder.
14. Turn the "FR" unit to 60 psi, and watch how the cylinder extends quicker.
15. Turn off the orange shutoff valve, cycle the Manually Operated Valve back and forth a couple of times so that there is no stored air in the system, unhook the hoses, and put everything away.
