Troubleshooting Common Pneumatic Air System Problems
Without the use of pressurized gas and air in a construction setting, there are an array of tasks that would prove to be almost impossible to accomplish. For this reason, the pneumatic systems that you have on site can be some of the most valuable pieces of machinery you have. It is not always feasible to stop and wait for several hours when you have a compressed air system down. Therefore, it is a good idea to know how to handle common issues on your own so you can get back on with the work at hand. Here are a few of the most common problems that can come up with your pneumatic air system.
Problem: Air pressure loss during operation.
Solution: The air pressure that is supplied by your pneumatic system is designed to be regulated by internal sensors that know when enough air pressure is supplied according to the set point on your controller. If the air pressure you receive through the outlet hose is less than what you have set, you are experiencing a loss of air at some point. In most cases, this is due to a faulty outlet hose. Therefore, this should be the first thing you check. Beyond the hoses, check connections for lost tension, filters for debris, and the power connection for low voltage issues.
Problem: Oil is dispersing along with air into machinery.
Solution: During times of high-output air pressure use, it is normal for a small amount of fluid or lubricating oil to be released with the air that is dispersed. However, if you notice fluids pooling in the equipment, there is a problem with the regulator valve that withholds pressure in the tank. In some cases, this is simply due to a clogged valve that is not allowing the forced air through for filtration before it is released.
Problem: You hear the system fueling up with air, but when activated, no air is released.
Solution: If you are positive that the compressed air system is fueling as it should, this could be related to the pressure control sensor that is normally just beneath the underside of the pressure tank. If the sensor is blocked, it will operate as if there is no air to be released. Clear the area, and try to activate the control lever again. If this does not fix the issue, you will have to get a replacement sensor.
Pneumatic air systems can get fairly complex when it comes to some maintenance aspects. However, there are many simple issues that can cause problems with how your machine functions. By taking the time to learn about the symptoms of the small issues and how they should be addressed, you will be better equipped to keep your compressed air system running in the long run. A compressed air equipment company, like Compressed Air Systems, can also help you maintain and replace your system as needed.
