Assembly sequence
1. Mechanical seal static component assembly:
A. will stop pin into the corresponding hole sealing end cover;
B. the static ring seal trap on the static ring, the static ring into sealed inside the end cover, attention should be paid to make the stop pin into the static ring grooves.Installing a gland, be careful not to make the static ring touch shaft - bolts should be evenly tighten several times.
2. Mechanical seal rotating parts assembly:
The mechanical seal of rotating parts in accordance with the order individually assembled onto the shaft.If a shaft sleeve, should combine the rotation of the mechanical seal parts in outside assembly on the shaft sleeve, and then will be equipped with mechanical seal sleeves loaded on the shaft of the rotating parts.
3. The end cover is installed on the seal, and evenly tighten the screw.
4. Dynamic test plate is easily, if the disk or demanding, should check the assembly size is correct.
Mechanical seals in manufacturing precision or installation accuracy requirements are very strict, if improperly installed, can affect the life of the seal and seal performance, serious when will make the seal failure quickly.
1. Check the type for installation of the mechanical seal, the specification is correct, the parts is missing.
2. Check the mechanical seal components are damaged, especially the sealing ring and static ring end face is bruised, when damage is found, and need to repair or replace new parts, the sealing element need gasoline or kerosene clean, keep on the surface of the dust and foreign bodies.
3. The shaft or sleeve surface and seal cavity wall, sealing end cover if there is a burr on the inner surface, the trench, etc.Burr is found, the trench should ponder, polishing, and gasoline or kerosene cleaning, keep clean, no dust debris attached on the surface.
4. Don't use a clean cloth or cotton cloth scrub ring and static ring surface, should use a clean soft cloth, such things as absorbent cotton swab.
5. In the process of the assembly should be kept clean to ensure that the ring and static ring sealing face no scratches,, in order to more in loading, should be in the shaft or sleeve assembly surface, daub oil gland with sealing ring surface, lest produce dry friction in the starting moment.
