the following guidelines are presented for the
maintenance personnel to follow during the
critical startup and break-in period:
1.
Fill
the
lube
oil
reservoir
with
recommended grade of oil. See "Power
End Lubrication," and FIGURE 3-1,
page 16.
2.
Fill the packing lube reservoir with
proper
oil.
See
"Plunger/Packing
Lubrication Recommendation Chart,"
page 20.
3.
Remove all inspection covers on the
top of the pump frame.
4.
Start the engine at the lowest possible
RPM and triplex pump at zero (0)
pressure. Make sure that all roller
bearings, crossheads, knuckle joints,
and crankshaft bearings are properly
lubricated.
5.
Increase the engine RPM to maximum
and check whether the vacuum reading
at the lube pump suction inlet is less
the 8" Hg or 4 psi or 0.28 bar.
6.
Check whether the lube system
pressure reading is at least 100 psi or
7.0 bar. Temporary pressure gages
should also be checked at this time to
make sure that all components of the
lube system are working properly.
7.
Check to see that oil flow back to the
reservoir is normal. (There should be
no accumulation in the power end.)
8.
Start the plunger lube system and
check to see whether it is adjusted
properly.
9.
Run at low speed to "work out" any
trapped air in the fluid cylinder with the
charge pump operating.
10. Run the pump at 80-90 strokes per
minute and 20% of its maximum
pressure rating for 30 minutes
11. During this time, observe the suction
vacuum gage reading, oil pressure and
temperature and check for leaks.
12. Run the pump at 80-90 strokes per min
at the following loads:
40% of full rated load 30 min
60% of full rated load 30 min
80% of full rated load 30 min
100% of full rated load 30 min
13. During the operation observe the oil
pressure and temperature, and inlet
suction vacuum gage reading, and
entire system for proper operation.
14. If the triplex pump is equipped with a
transmission, run the pump for 30 min
in each gear in the higher gear ranges
pulling full horsepower in each gear.
Observe closely oil pressures and
temperatures, and lube oil suction
vacuum.
15. Shut the pump down and let it cool
thoroughly
before starting normal
operation of the pump.
16. During the shutdown, change the oil
filter elements and clean the suction
strainer.
17. Change the lube oil and clean the
reservoir to get rid of metal particles
and any other wear products now
present in lube oil system.
18. Change filter elements and clean
strainer every 10-15 hours, till it
becomes apparent that wear-in process
is finished.
19. Tighten all fluid cylinder attachment
nuts, procedure listed in "Fluid End
Removal and Installation,” page 21,
after 50-70 hours of pump operation.
See FIGURE 4-1, page 22.
20. Change the lube oil again, replace the
filter elements, and clean the strainer
after 80-100 hours of pump operation.
21. Follow
the
routine
maintenance
schedule described in the next section
after completion of the wear-in period.
