Mechanical Seal
Installation Precautions
1. Assembly must be clean and smooth. The parts of mechanical
seals, related machinery and equipment parts, tools, lubricating
oil (grease), wipe materials (cotton yarn, white cloth, silk, etc.)
must be very clean. The sealing end face of the dynamic and static
ring should be wiped with white silk or soft gauze.
2. Trimming and chamfering of chamfers, shafts, sealed end caps,
etc. shall be trimmed smoothly, and the relevant corners of the
shaft and end caps shall be sanded and polished.
3. During installation, apply turbine oil or l0 oil on the moving
ring and static ring (especially on the seal end blood), auxiliary
seal ring, shaft, and end cap to reduce friction, so as not to
damage the seal of the static ring. End faces and auxiliary seals.
4. Assemble the auxiliary sealing ring.
1) Rubber auxiliary seals cannot be soaked and washed with gasoline
or kerosene to avoid swelling and deformation and premature aging.
2) After the O-ring is installed on the moving ring assembly or
static ring assembly, it should be logical to prevent it from being
twisted, so that the burr is in the cross-section when it is free.
O-rings that are slightly rough on the burr can be used if the burr
segment is 45o. However, care should be taken in the position of
the burrs. When pushing the component, one side of the O-ring and
the seal (gland or seal cavity) slide relative to each other. The
burr on the side should be behind the sliding direction. Otherwise,
the burr will be turned up and sealed. In position, it affects the
sealing effect.
3) When pushing the assembly, prevent the O-ring from being
damaged. The main forms of damage are drop, nick, bump, curl and
twist.
5. Adjust the mechanical seal compression amount according to the
technical requirements. For the value, refer to the product manual.
Otherwise, the amount of compression is too large, which increases
the specific pressure on the end face and accelerates the wear of
the end face; if it is too small, the specific pressure on the end
face of the moving ring and the dense ring is insufficient, and the
seal fails.
6. The static ring assembly should be installed into the gland (or
sealed cavity) using a press or a drilling machine. Under no
circumstances should mechanical seal parts or components be
impacted. The pressed surface should be covered with clean paper or
cloth to avoid damaging the sealed end.
7. After assembling the moving ring or static ring assembly, press
the compensation ring by hand to check whether it is installed in
place and whether it is flexible; elastic split ring (in some
mechanical seals, the elastic split ring axially positions the
compensation ring) Reliable positioning.
8. Check whether the perpendicularity between the sealed end and
the centerline of the shaft (or shaft sleeve) meets the
requirements.
9. The anti-rotation pin lead of the static ring component must be
accurate. When pushing the static ring component, the pin groove of
the component must be aligned with the pin. After pushing in place,
the distance from the end surface of the component to one end of
the sealed cavity is determined to determine whether it is in
place.
10. When tightening the end cap by tightening the bolts, use even
force, symmetry, and care. Tighten it several times. Do not tighten
it at one time to avoid skewing or even crushing the static ring.
11. After the moving ring is installed, it must be ensured that it
can move axially on the shaft flexibly (press the spring with the
moving ring and then spring back freely).
