What might cause a pneumatic actuator to be unresponsive?

Air supply contamination is a critical factor that can cause a pneumatic actuator to become unresponsive. When contaminants such as dirt, moisture, or oil enter the pneumatic system, they can obstruct airflow and disrupt the normal operation of the actuator. Contaminants can lead to blockages in the actuator itself or in the hoses and fittings that supply air to it, causing the actuator to not move as intended. Moreover, contamination can damage internal components, potentially resulting in increased friction or mechanical failure, which further impairs the actuator’s function.

In contrast, excessive lubrication could potentially create a slippery barrier between moving parts but is less likely to cause total unresponsiveness compared to contamination. Regular maintenance checks are essential for identifying issues before they develop into significant problems, and proper alignment with connecting components ensures that the system operates efficiently. However, neither of these factors can degrade the performance of a pneumatic actuator as severely or directly as contamination can.
