The multi-stage centrifugal pump has high vibration
Thread Content
I would like to ask everyone: for a multi-stage centrifugal pump, if one wants to replace the balance disk, is it possible to simply remove only the bearing housing on the side of the balance disk and the mechanical seal? If the coupling cannot be removed for measurement, will the measured play value be accurate? What should be paid attention to? I need expert advice.
Pumps come in various designs, and it is best to replace the balance disc directly with the original one. The choice of replacement method can be whatever is convenient and feasible, as long as it does not damage other parts. For some reason, is it necessary to replace the balance disc? How about replacing the rotor assembly? For reference.
As I understand it, the serial number has little to do with the installation position of the shaft; it’s a through shaft, so you can remove only the side containing the balance disc. In fact, that’s what the manufacturers do as well. However, removing the balance disc might not be as easy as you think. You can ask the manufacturer for specific instructions on how to proceed. Measure the shaft’s installation dimensions when removing it, and then restore them to their original state when reinstalling it
No, multi-stage pumps are primarily regulated based on the displacement amount. If you don’t disassemble them, the total displacement and the partial displacement won’t be accurate, and this could lead to bearing damage once the pump is reassembled
Just disconnect the coupling using your method
High vibration has nothing to do with the balance disc; we’re a bit confused
Sure, but vibration has little to do with the balance disc; your discussion isn’t really related to your question either.
