4 Signs Of A Failing Pneumatic Actuator
Posted in Uncategorised, on October 31, 2022 By Admin
Pneumatic actuators are devices that use compressed air to generate linear or rotary force and motion. They are used in a variety of industries, such as automotive manufacturing, aerospace, and food and beverage processing. Pneumatic actuators are often used because they are less expensive than other types of actuators, such as hydraulic or electric actuators. However, this does not mean that pneumatic actuators are immune to wear and tear. In fact, there are several signs that can indicate a failing pneumatic actuator. Here are 4 signs that clearly indicate that an actuator needs replacement.
Signs of a malfunctioning pneumatic actuator.
Erratic Load Movement
As a general rule, pneumatic actuators should provide stable and consistent load movement in order to maintain proper functionality. However, over time, actuators can begin to experience issues that cause the load movement to become erratic. This can be caused by a number of factors, including wear and tear on the internal components, air pressure fluctuations, or even damage to the unit itself.
Cylinder Drift
When a pneumatic actuator is beginning to fail, one of the first signs is cylinder drift. This is when the cylinder starts to move on its own, without any input from the actuator. Cylinder drift can be caused by a number of things, including loss of air pressure, problems with the seals or piston, or the cylinder itself.
It's important to take immediate action with this issue. Otherwise, the cylinder could continue to move until it damages the equipment it's attached to. In some cases, cylinder drift can even cause an accident.
The Actuator Is Stuck
If your pneumatic actuator is stuck in an open or closed position, it may be due to a variety of factors. The most common cause is a build-up of dirt, dust, or debris in the actuator. This can cause the actuator to become seized, making it difficult or impossible to move. If a pneumatic actuator is stuck in one position, it needs to be repaired or replaced as soon as possible.
Leaks
One of the most common signs of a failing pneumatic actuator is leaks. A consistent leak can lead to loss of pressure and poor functioning/displacement. If it isn’t promptly addressed it can render the whole actuator inoperable. Usually, the major culprits here are worn-out seal, which eventually occurs due to the constant motion of internal metal components.
These are the four main signs that something is malfunctioning in a pneumatic actuator, and can eventually lead to failure. Ways to fix and troubleshoot these problems will be explored in the next blog.
