Scheduled Maintenance
The 40K UHP pump operates at very high pres-
sure and has specific lubrication and maintenance
requirements. Refer to the Maintenance Matrix
in this section and the pump manufacturer’s op-
erating and maintenance manual for lubrication
specifications and maintenance schedules.
Daily Inspection and Maintenance
•
Check the crankcase lubricating oil level.
NOTICE:
THE PROCEDURE FOR CHECKING THE CRANKCASE OIL
LEvEL IS DIFFERENT FOR WHEN THE PUMP HAS NOT BEEN
OPERATING FOR 5 OR MORE HOURS AND WHILE THE PUMP IS
IN OPERATION. REFER TO UHP PUMP CRANKCASE OIL LEvEL
CHECK PROCEDURE IN THIS SECTION FOR THE CORRECT
PROCEDURES FOR CHECKING THE CRANKCASE OIL.
•
Check for obvious loose mounting nuts and
bolts.
• Inspect all hoses, fittings, valves and seals for
leaks and proper operation. Repair or replace
leaking or malfunctioning components before
operating the system.
• Make sure cooling water is flowing to the
plunger packing seals when the charge water
is activated. Constant water flow is essential
to lubricate and cool the seals. Adjust flow
with the metering valves or replace packing
if necessary.
•
Make sure the cooling water sump and drain
are clean for proper drainage.
•
Check for water dripping from the UHP Pump
manifold weep holes during the high pressure
test. Water dripping from the square holes
indicates the face seals are leaking. Water
leaking from round holes indicates the high
pressure seals are leaking. Find and correct
the problem before beginning water blasting
operations.
•
Test the dump valve for proper operation daily.
Never operate the system if the dump valve is
not working properly.
•
Test the Hydro-Throttle controller to make sure
it is operating properly.
