Module code and name

PN 4- Control the speed of a single acting cylinder

Overview

You will be learning towards the outcome “Control the speed of a single acting cylinder”

Key and critical concepts you will learn

You will be learning towards the outcome “Control the speed of a single acting cylinder”. Whilst learning towards the outcome you will be required to achieve the following:

  • Know the function of a variable flow control valve.
  • Know the function of a check valve / non – return valve.
  • Know the function of a quick exhaust.
  • Know how to construct a circuit controlling the speed of a single acting cylinder.

On completion of this module, the learner must be able to:

  • State the function of a variable flow control valve.
  • State the function of a check valve / non – return valve.
  • State the function of a quick exhaust.
  • Construct a circuit controlling the speed of a single acting cylinder.

During this process you must adhere to certain specified requirements as listed in the Module.

Tools, consumables, equipment and machinery required

  • Schematic diagram
  • Training Panel
  • Single Acting Cylinder
  • Quick Exhaust Valve
  • Adjustable one way control valve
  • 3\2 way directional control valve,  normally open.
  • 3\2 way directional control valve, normally closed.

Prerequisite modules

ST- Safety

Application

In module PN-1, it was explained that the speed of a cylinder is dependent on the flow of air supplied to it. Therefore, if the amount of air that flows to a cylinder can be controlled, the speed of the cylinder can be controlled.
