Distinguish the sounds of the pump outlet, pump inlet cavitation, and pipe elbows and valves
Thread Content
When the pump is running, there are noises from the motor at the site, noises from the pump’s outlet, sounds from the pipes connected to the pump’s outlet (such as elbows and valves), noises from the pump itself. Under certain conditions, there is also noise caused by cavitation at the pump’s inlet, in addition to ambient noise. Can those with keen hearing distinguish between all these noises? Is this an essential skill for on-site personnel?
This can only be achieved by gradually gaining experience through actual work, as well as by learning to distinguish between the different sounds in each area; after all, there are differences among those sounds. It depends on the level you want to reach personally.
Basic skills of equipment maintenance personnel
Use a tube to press against a certain area, and listen with the other ear
The various types of noise mentioned by the poster are different from each other and do not originate from the same source; once the source of the noise is identified, it becomes relatively easier to determine and analyze it.
Listen more and you’ll understand. If there’s no problem, just go and check things out in person; if one day the sound becomes abnormal, you’ll immediately feel unwell
Inspectors carry stethoscopes; when passing by a device with a problem, they can hear a different sound, and by comparing it to the normal sound, it’s easy to detect the issue.
