Speed Control Flashcards
(8 cards)
What is a unidirectional flow regulator used for in a pneumatic system?
It controls the speed of a pneumatic cylinder by restricting airflow in one direction while allowing free flow in the opposite direction.
How do you identify a unidirectional flow regulator symbol in a circuit diagram?
A valve symbol with an arrow passing through a restriction in one direction and a free-flow symbol (an open arrow) in the other.
How is a unidirectional flow regulator used for speed control?
It slows down the movement of a cylinder by restricting the exhaust air from the cylinder or controlling the air entering it.
In which part of a circuit would you typically place a flow regulator for speed control?
In the exhaust line of a single acting cylinder or on the supply line depending on the desired control.
What happens to the cylinder’s speed if you tighten the flow regulator?
The cylinder moves more slowly as airflow is more restricted.
What happens to the cylinder’s speed if you open the flow regulator?
The cylinder moves faster as airflow restriction is reduced.
How would you use a unidirectional flow regulator to incorporate speed control into a pneumatic system?
By connecting it in line with the cylinder’s exhaust port or supply line, adjusting the regulator to control airflow and thereby controlling the piston’s speed.
Why might you control the speed of a pneumatic cylinder?
To improve safety, precision, or to match the timing of a sequence in a pneumatic control system.
