PERIODIC
ROUTINE
MAINTENANCE
SCHEDULE
Performance
of
the
periodic
routine
maintenance tasks, described in this
section, will ensure long, economical, and
trouble free operation of this pump. It is
highly recommended that the customer set
up a maintenance program during the run-in
period. The periodic maintenance data
should be recorded and kept with other
pump
documents.
The
following
recommendations,
based
on
previous
experience, should serve as a guideline for
establishing a good maintenance program.
The periodic maintenance schedule is
divided into daily, monthly, and quarterly
tasks to be performed by the user after the
pump has gone through 100 hours of wear-
in period. For the tasks performed during
the wear-in period, see "Startup and New
Pump Run-In Procedure," page 17.
Daily Routine Maintenance Tasks
1.
Check the oil level in the lube oil
reservoir.
2.
Periodically monitor lube oil operating
pressure and temperature. Minimum oil
operating pressure is 50 psi. The
maximum oil operating temperature
depends on a particular grade of oil
used in the pump lube system. (See
FIGURE 3-1, page 17).
3.
Check the lube pump suction inlet
vacuum. A vacuum gage reading
higher than 8" Hg or 4 psi or 0.28 bar
indicates that the suction strainer
and/or oil filter element are clogged.
The strainer must be cleaned, and the
oil filter element replaced
as
necessary as soon as the pump can be
shut down for a short period of time to
perform these tasks.
4.
Listen for any abnormal noise or rough
operation, which may indicate the need
for fluid end maintenance such as
changing valves or valve seats. Due
to very high pressures in the triplex
pump fluid end, worn valves and seats
should be changed as soon as possible
to prevent washing them out with the
pumped fluid.
5.
Check the plunger/packing lubrication
pump for proper operation. Insure
packing nut is tightened sufficiently into
stuffing box. Recheck tightness after
extended continuous operation.
Monthly (100 hour) Routine Maintenance
Tasks
1.
Clean the strainer and replace the oil
filter element.
2. Check the entire lube system for leaks
and eliminate them.
3.
Check all fluid end expendables such
as valves, packings, and valve seats
and replace them as necessary.
4.
Check the extension rod seals and
replace them as necessary.
Quarterly (300 hour) Routine
Maintenance Tasks
1.
Change the lube oil and clean the oil
reservoir thoroughly.
2.
Clean the lube system strainer and
replace the oil filter elements.
3.
Re-tighten the critical bolt joints
following torque specifications given in
Section 6.
4.
Add grease to the tie rod sleeves to
prevent corrosion.
5.
Clean or replace the breather cap filter
element.
6.
Check all pressure, temperature, and
vacuum gages for proper operation
and replace as necessary.
7.
Check all lube system warning and
alarm devices for proper operation and
replace if found defective.
8.
Check supply of on hand expendables
such as packings, valves and seats,
maintenance items such as seals, O-
rings, oil and breather filter elements,
and also maintenance tools. Order to
replenish supplies as necessary.
