Please explain the concept of shaft movement in centrifugal pumps

It’s best to start from the beginning; searching on Baidu only results in confusion
First, mention the case – it’s best to start from the beginning: what constitutes the beginning, to what extent, and who will be responsible for discussing it. So, first raise specific questions and provide a comprehensive and scientific description; add whatever is needed, and it’s advisable to include data as well. . . . I’ll click wherever I don’t know how. For example, when it comes to writing and reading characters, one should learn whichever is harder or ask about that aspect. It would be best to explain how to read characters, perhaps starting from the first page of a dictionary Well, let me guide you to your question: Is it one shaft or several shafts that are experiencing shaft play? How serious is the problem? What is the amount of displacement deviation? What type of pump is it, and what are its flow rate, head, and power specifications? Also, how was it installed? Vibration conditions, current conditions, bearing temperature, impeller type, material properties? Wait, the operation methods – write down everything that comes to mind.
Change ’several shafts’ to ’several pumps’; error in typing on mobile phone
Well, do all single-stage centrifugal pumps have shaft play? What is the impact of shaft runout? How to adjust shaft play? What is the principle behind it?
Generally, the issue with shaft misalignment is due to improper adjustment of the thrust bearings, as well as inadequate control of the clearance around those bearings. Well, it’s actually quite simple; it’s just difficult for those who don’t know how to do it, but not for those who do.
I don’t know as much theory as you do; I can only analyze simple cases.
There is a lot of material in Baidu Wenku. .
When the head of a single-stage centrifugal pump is not very high, thrust bearings are generally not used; deep groove ball bearings are employed instead. As long as the bearings are installed in place, no adjustment is required
When asking questions, it is indeed necessary to have a clear goal and provide detailed background information. Problems shouldn’t be raised in a vague manner.
