so as not to break the seat, and not to damage the bore of
the seat by hitting it against the shaft (2100).
(3)
Apply an appropriate amount of oil to the packing (4100)
or the O-ring (4120.2), and the shaft. Then, fit the
mechanical seal for the rotary side on the shaft, according
to the dimension A (shown in Figs. Fig 5.2-2, 5.2-4, 5.2-5,
5.2-6, Fig 5.2-7,
Fig 5.2-8
and 5.2-10) (P.14
−
P.18), and
fasten the mechanical seal with the set bolt (9040) securely.
Mechanical seal of LCA type:
a) Insert the follower (4740) and the spring (4770) in proper
orientation.
b) When inserting the washer (4720) and the stopper (4850),
align the engaging clutch properly.
(4)
After completion of the above mounting procedure,
re-check if the set bolt is securely tightened, and make sure
that the washer normally works.
(5)
Mount the casing cover (1610) to the bearing housing
(3300).
(6)
Mount the seal cover to the casing cover. First, tighten the
cover temporarily according to the procedure described in
Section 4.3 (P.12). After mounting the impeller (2300),
tighten the cover completely.
[C] Double mechanical seal (LTW type)
(1)
Put the O-rings (4120.1 and 4120.2) in the seats (4750.1
and 4750.2), and insert the seats into the casing cover
(1610) and the seal cover (4710), respectively.
For the mounting procedure, refer to Section 5.6.1 [B], (1)
(P19).
(2)
With the mechanical seal for the fixed side mounted to the
seal cover, put the O-ring (4120.3) in the seal cover. Fit the
seal cover on the shaft (2100), and slide the seal cover
toward the bearing housing (3300). When mounting the
seal cover to the shaft, use thorough caution so as not to
break the seat (4750.1), and not to damage the internal
surface of the seat by hitting it against the shaft (2100).
(3)
Apply an appropriate amount of oil to the packing (4100.1)
and the shaft. Then, insert the set of washer {washer
(4720.1), follower (4740.1), packing (4100.1) and spline
ring (5061.1)}, spring (4770.1) and stopper (4850) in
sequence.
Fit the stopper on the shaft according to dimension A
(shown in Fig 5.2-3 (P15)), and fasten the stopper with the
set bolt (9040) securely.
(4)
Apply an appropriate amount of oil to the packing (4100.2)
and the shaft. Then, insert the spring (4770.2), and the set
of washer {washer (4720.2), follower (4740.2), packing
(4100.2) and spline ring (5061.2)} for the liquid contact
side in sequence.
(5)
With the mechanical seal for the fixed side mounted to the
casing cover, mount the casing cover to the bearing housing.
When mounting the casing cover to the bearing case, use
caution so as not to break the seat (4750.2), and not damage
the interal surface of the seat by hitting it against the shaft.
(6)
Mount the seal cover to the casing cover. In this step, make
sure that the flushing outlet port is placed vertically upward.
First, tighten the cover temporarily according to the
procedure described in Section 4.3 (P.12). After mounting
the impeller (2300), tighten the cover completely.
