Questions regarding the mechanical seal positioning block
Thread Content
I would like to ask whether it is necessary to keep the positioning blocks for mechanical seals What role does he play? A set of modular mechanical seals comes with positioning blocks when it is supplied; these blocks need to be removed after the seals have been installed. How is the compression amount ensured in this case? Should I tighten the back cap after crushing the impeller? Similarly, when I disassemble the mechanical seal, does the positioning block need to be restored? Can’t I tighten the impeller after removing and reinstalling the positioning block?
Actually, this thing is just an auxiliary device, similar to a positioning pin or a guide rod. The purpose is to achieve the principle of adaptation. For reference.
Keep it as it was when it was removed – this relates to the issue of maintenance practices. The seal positioning clips serve to effectively protect the stationary and rotating rings from accidental damage during installation and removal. By keeping things as they were, the original components can be preserved; this not only helps in identifying the causes of abnormal wear but also allows those components to be reused after being ground down.
