The coupling makes unusual noises
Thread Content
It’s that plum-blossom coupling which makes a clicking sound after rotating a few times; why is that? I’d appreciate everyone’s advice
1 Check whether the elastic block is damaged. 2 Check whether the coupling has any axial movement. 3 Check whether it is properly centered as specified.
Reply to 1# juanzhangjx: 1. Is it in operation or just rotating? 2. What’s the situation after the maintenance? 3. What was mentioned on the 2nd and 3rd floors covers most of the aspects; in addition, check whether the keys are worn out and whether the keys fit properly in their slots
Check the lubrication system and shaft pins for any abnormalities
If the noise comes from the coupling, the answers for the 2nd and 3rd floors are clear; if it comes from the bearings or the pump body, then it is necessary to check the bearings or disassemble the pump body for inspection.
This kind of situation has also occurred in my workshop recently; it’s the same as what was reported on the second and third floors
