When considering the stroke length for
pneumatic piston actuators, several factors need to be taken into account.
Application requirements are crucial. The
specific task the actuator is meant to perform dictates the necessary stroke
length. For example, in a valve - control application, the stroke length must
be sufficient to fully open and close the valve to regulate the flow of fluid
or gas accurately. If the stroke is too short, the valve may not operate
properly, leading to inefficiencies or even system failures.
Space limitations also play a significant
role. The available space in the installation location restricts the maximum
stroke length that can be accommodated. In compact industrial settings or
machinery with limited room, a shorter - stroke actuator might be preferred to
fit within the available space without interfering with other components.
Force and speed considerations are related
to stroke length as well. Generally, a longer stroke length may require more
force to move the piston through the entire range and can affect the actuator's
speed. If high - speed operation is essential, a shorter stroke length might be
more suitable, as it allows for quicker movement of the piston with the same
amount of air pressure. Additionally, the force - output requirements of the
application should be matched with the appropriate stroke length to ensure the
actuator can perform the intended task effectively.
