How to install the rotating ring of a mechanical seal
Thread Content
Is it the spring seat that compresses the spring, with the protruding part of the moving ring fitting into the recess in the spring seat, and then the hex key is used to tighten the spring seat?
This type of seal uses a fork drive. Has the position of the static ring been fixed? If it has already been fixed, align the protruding part with the recessed part, compress the spring, then pull it back a few mm, and finally tighten the set screw. If the position of the static ring has not yet been fixed, it is necessary to measure its dimensions when the seal is functioning properly. Then, the drive seat and the moving ring should be fixed to the shaft, and finally the end cap should be tightened.
As mentioned on the 2nd floor, the clamping force of a dynamic and static mechanical seal is very important
The maximum compression amount of this large-spring type mechanical seal accounts for 60%–70% of the total length of the spring, and it is used in applications where the axis length is large while the radial dimension is small!
