[F] Handling check sheet
To Be Checked At Installation.
1. No serious defects shall exist on the shaft sleeve surface and the seal mounting
surface of the hull.
2. Epoxy Paint (Eagle Paint) must be applied on the surface of the shaft sleeve where
the sealing is installed.
3. Liquid packing must be applied on the gaskets and the cut faces of the mating
ring.
4. The casing shall be installed with its "TOP" mark at its top position.
5. The casing shall be aligned to the shaft sleeve surface within 4mm
±
0
.
5mm.
6. A thin coat of grease shall be applied to the surface of the shaft sleeve when
the seal ring is installed.
7. Wipe away surplus of grease with your hand.
8. There must be no partial deformation of the seal ring. The seal ring shall be
installed in correct direction.
9. Nothing clogged in the grooves of outside sliding surface of seal ring.
10. No steps,warping or damage shall be on the sliding surface of the mating ring.
11. Remove grease from the sliding surface of mating ring and seal ring completely
with solvent.
12. All pipings shall be set as required.
13. The grounding device must be installed in effective position.
14. Check if a pressure-reducing valve is necessary for the air pipe line.
To Be Checked After Installation.
1. Sealing performance must be confirmed in the following manner. Pressurize the
inflatable ring to 0.3
～
0.6 MPa and set feed water pressure at equivalent to twice
draft pressure then perform air venting. There shall be no continuous leaking
from the sliding surface and air pressure downfall must be 10%/Hr,or less.
2. Pressurizing air supplied to the inflatabie ring shall be eliminated after the
above mentioned performance confirmation.
To Be Checked At Launching.
1. Performance of the inflatable ring shall be confirmed when the propeller shaft
is stopped.
2. The inflatable ring shall not be run without fixing the propeller shaft at
launching.
3. When the propeller shaft is stopped, Fully close the valves in the feed water
line and pressurize the inflatable ring to 0.3
～
0.6 MPa Then open the plug and
make sure of no water leakage from the casing.
4. After the above item 3 are confirmed, purge air in the inflatable ring shall be
done.
5. No excessive leakage shall occur from the sliding surface (Max.2 L/Hr.).
6. Air venting of the sealing device shall be performed.
7. Operation control of valves shall be done without fail.
To Be Checked During Operation.
1. The supply water pressure is draft pr0.01
～
0.03 MPa in close vicinity
to the seal.
2. Sealing condition shall be without problem at any time such as at stoppage, during
forward and back sailing, in rough weater condition, at empty or full load
condition, etc.
3.
The coupling for the air pipe line shall be released.
