Adjustment method for double-end face mechanical seals

Double-end face mechanical seals require zero leakage
Flushing schemes for pressurized double-end mechanical seals such as 53ABC, 54, etc., can achieve zero leakage of the process medium
The shaft assembly is equipped with two moving rings; how to adjust the axial position of these two moving rings?
The positioning dimensions are calculated based on the working height of the seal; generally, there are positioning platforms or lines on the container seal.
If there are no alignment marks on the mechanical seal, it is best to measure and calculate the compression amount by yourself, ensuring that the compression is equal on both ends.
Currently, tandem double-end face mechanical seals are commonly used. The compression amount of the seal is usually fixed; it can be determined and may also be adjusted appropriately!
For the installation style of dual-machine seals, is there already a back-to-back type?
As for the compression amount, there is usually a processing line. If you’re too lazy to calculate the compression amount, simply mark the original disassembly and assembly positions, and then proceed with measurement and assembly. Actually, it’s more practical to learn how to measure.
In the case of a packaged seal, there are definitely positioning plates, and it can be adjusted back into place. For a loose-seal type, please refer to the installation dimensions provided by the manufacturer of the mechanical seal, and adjust it according to those specifications
