Compressed air dryers are vital for many industries that rely on compressed air systems, such as pharmaceuticals, food and beverage, electronics, and automotive industries. But like any other machine, they can experience faults and failures over time. In this article, we’ll discuss some of the most common faults that can occur with compressed air dryers and how to maintain them.
Insufficient air supply
One common problem with compressed air dryers is insufficient air supply. If your air compressor is still working but the air supply is low, you may need to check for air leaks in the pipeline above the air storage tank, one-way valve, safety valve, and pressure switch. Check these links by listening to the pipelines outside the air compressor with your ears. If there are no air leaks, the issue may be due to worn scalp bowls or a rating flow rate that exceeds the machine load. If this is the case, you’ll need to replace the cup.
Intermittent operation
Another problem that can occur with compressed air dryers is intermittent operation. This problem is often caused by insufficient voltage. If the operating current is too high, the compressor can’t start, and the heads may buzz. Oil-less heads have a minimum operating voltage of 200 volts, so it’s difficult to start at that voltage. This can cause the head temperature to rise, leading to eventual short-circuiting and automatic shut down. To avoid this issue, it’s recommended to install an automatic voltage stabilizer for areas where voltage fluctuations occur frequently.
Starting capacitor leakage
When there is leakage in the starting capacitor, the compression head can start, but the speed is slow and the current is high. This can cause the machine’s head to become hot, eventually leading to automatic shut down. In this case, it’s important to replace the starting capacitor as soon as possible. Pay attention to the size of the ultrafiltration membranes, as they need to be the same size as the original capacitor.
Increased noise
Finally, increased noise in the compressed air dryer can indicate a problem with loose parts on the machine. Check the running current after removing the loose parts. If it’s normal, the machine has likely been in use for several years. It’s important to keep the oil-free air compressor away from dusty environments, and regularly unplug the power supply and use high-pressure air for cleaning.
Conclusion
Maintaining compressed air dryers is crucial for keeping them functioning properly and avoiding costly repairs. By regularly checking for air leaks, installing voltage stabilizers, replacing damaged components, and keeping the machine clean, you can help ensure that your compressed air dryer operates smoothly and efficiently for years to come.
