Assembly sequence of
mechanical seals
1. Mechanical
seal stationary member assembly:
a.The
anti-rotation pin into the corresponding hole of the sealing cap;
b.Place
the static ring seal ring on the stationary ring, the stationary ring mounted
in a sealed cover, to pay attention to the anti-rotation pin into the
stationary ring groove. When installing gland, careful not to touch the
stationary ring axis - several times the bolts should be tightened evenly.
2.
The mechanical seal rotary member assembly:
Rotating
member of the mechanical seal assembly in accordance with the order one by one
onto the shaft. If bushings, will have on the outside of the rotating parts of
the mechanical seal in order to assemble the sleeve, and will be equipped with
a mechanical shaft seal rotating parts kit onto the shaft.
3.
The cover is mounted on the seal, and tighten the screws evenly.
4.
Barring test is easy, if the disc does not move or difficult, you should check
the assembly dimensions are correct.
Mechanical
seals in terms of manufacturing precision or accuracy installation requirements
are very strict, if not installed properly, it will affect the life and sealing
performance of seal, the seal will be serious to fail.
a.
Check the mechanical seal to be mounted models, specifications are correct,
whether the missing parts.
b.
Check the mechanical seal if there is damage to the components, especially the
ring and stationary ring seal face is bruised, if found damaged ,when in need
of repair or replacement of parts, each sealing element required gasoline or kerosene
to clean keep each element surface free of dust, foreign matter.
c.
The shaft or sleeve surface and the seal cavity wall, the surface is sealed
cover burrs, grooves and the like. If found glitches, grooves should Shuhei,
lighting, and with gasoline or kerosene to clean, clean, must not have dust
debris attached to the surface.
d. Do
not use a clean cloth or cotton cloth to scrub the ring and stationary ring
surface, use a clean, soft gauze, absorbent cotton stuff like scrub.
e.
The assembly mechanical seals process should be kept clean to ensure that ring, not static ring
seal face is scratched and grazed, for more on the load, it should fit in the
shaft or sleeve surface, gland and seal mating surface smear oil, in order to
avoid start instant dry friction.
