Problems with the balance disk
Thread Content
Whether it is a multi-stage centrifugal pump or a multi-stage centrifugal compressor, the balance disk is generally located on the outlet side. But is there any case where the balance disk is placed on the inlet side? Wish all marine friends a happy celebration of both National Day and the Mid-Autumn Festival!

Yes, but very rarely. This question reminds me of an old one from before. Why is the pump outlet usually on the non-driving side? Many people say it’s a convention; as for why exactly, I’ve also forgotten. Let’s use this as a basis for now: the outlet is located on the non-driving end. When the balancing mechanism is placed on the non-driving end, it is not necessary to remove the coupling if maintenance of the balancing mechanism is required, which saves one processing step. That’s how I understand it.
What I’ve seen is installed on the outlet side of the centrifugal pump!
Then you don’t understand how the balance weight works; it’s impossible to install it on imported models.
Based on the working principle of the balance disc, it isn’t installed on the inlet side! Take a look at this post: What’s the difference between a balance disc and a balance drum? Why does the balance disc have a seal ring? http://bbs.hcbbs.com/thread-983503-1-1.html
The balance disc or balance drum is installed behind the final impeller, that is, on the outlet side. I’ve never seen it installed on the inlet side as you mentioned; I guess someone has suggested that approach before, but it doesn’t seem to work very well. In any case, it’s common to install it on the outlet side. By understanding how axial force is generated and how the balance disk (drum) functions, one can comprehend this concept.
First, figure out how the white balance dial works, and then you’ll understand why it isn’t placed at the entrance – every design has a theoretical basis
Everything has its reason; just like a person’s ears, eyes, and eyebrows – they are located in fixed places for a reason as well!
