Do piston compressors often make unusual noises?
Thread Content
After being used for a period of time, piston compressors often produce abnormal noises in their cylinders; how should this be dealt with? Does the machine generate significant vibration after operating for a while?
If the valve disc is damaged or the gland screws are loose, abnormal noises will be produced. The temperature can be used to determine which valve has a problem, allowing for targeted repairs.
If you hear abnormal noises, it’s best to stop the vehicle and check it out to avoid more serious problems
It’s possible that the cylinder liner has loosened. One of our company’s hydrogen circulation compressors encountered this problem; its cylinder liner is of the type that can be pulled out, and it moves back and forth continuously driven by the piston
It is recommended to check the cylinder and air valves; it’s possible that the air valve has broken and fragments have fallen into the cylinder, or it’s possible that the piston is loose. It’s also possible to have liquid present. As mentioned on the second floor, it is possible to determine which stage has a problem based on the exhaust pressure and temperature, allowing for targeted disassembly and inspection.
There are many reasons for abnormal noises: loose valves, broken valve plates, worn piston rings, etc. It depends on the area where the sound is heard to determine it. A compressor that makes abnormal noises must be shut down for inspection; it can only be used normally after the issue is resolved.
Abnormal noises in the cylinder: 1. Loose valve stem screw； 2. With liquid ； 3. Loose piston ； 4. Damaged piston rings ； 5. Loose cylinder liner ； 6. The clearance is too small.
First, check whether there are any issues with the process – is an industrial liquid used or not? After exclusion, check the valve assembly to see if there are any significant changes in pressure at various stages ； Check the piston assembly again to see if there is a noticeable tendency for the piston rod to sink.
