2.
Fill the plunger reservoir with proper
oil. See “Plunger/Packing Lubrication
Recommendations” on Page 19.
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 have
proper lubrication.
5.
Increase the engine RPM to
maximum operating speed 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 be also 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 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. Se
“Power End Internal Lube System,”
page 12.
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
minute 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
minutes in each gear in the higher
gear ranges pulling full horsepower in
each
gear. Observe the oil
pressures, temperatures, and lube oil
suction vacuum closely.
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 the
strainer every 10-15 hours until it
becomes apparent that the wear-in
process is finished.
19.
Change the lube oil again, replace
the filter elements, and clean the
strainer after 80-100 hours of pump
operation.
20.
Follow the routine maintenance
schedule described in the next
chapter after completion of the wear-
in period.
