Is it scientific to position the pump shaft like this?
Thread Content
In the past two days, I encountered a submersible pump with five sections and four shafts connected by threads to form one shaft. With an impeller, the pump has a 7312BECBP bearing, and five graphite-filled PTFE sliding sleeves. The pump is about 8 meters long. I always feel that an angular contact ball bearing is not so reliable for axial positioning. Who has seen it?
Sir, the main function of the bearing of 7312BECBP is not for positioning. I think it is more to bear the weight of the rotor.
The original poster is worried about whether an angular contact ball bearing can bear the weight of the rotor and that there will be problems with the bearing capacity. You can ask the pump manufacturer to do the calculation and you can rest assured if the calculation certificate is given.
