ROUTINE CHECKS AND MAINTENANCE
Whenever equipment is provided with pure (dry sump) oil mist lubrication, it is important to insure
constant, uninterrupted operation of the oil mist lubrication systems. If a malfunction occurs, early
detection and corrections are important.
The daily operation of the oil mist system for the process operator has been reduced to checks of
the IVT Oil Mist Generator and lubricated equipment and to emergency procedures in the event
of a major malfunction. Except for emergencies, routine adjustment of the oil mist generator is
not required. Each oil mist system, once installed and balanced, supplies a constant amount of
oil mist to a number of lubrication points. Any change in the oil mist pressure or in the regulated
air pressure (load pressure) from the initial set points is an indication that some component has
failed. Minor adjustments that might offset the failure symptoms may lead to more serious
problems before detection and corrections can be made.
Keeping system adjustments to a minimum is intended to make the oil mist systems more reliable
and to insure proper operation. It is not meant to discourage the natural troubleshooting initiative
of the process technician. Operators should be familiar with "Model IVT Operating Guide",
knowing how to read gauge values and alarm settings before attempting these procedures.
1) DAILY OIL MIST GENERATOR CHECKS
a) Check mist header pressure setting @ 20 inches H
2
O / 50 m BAR
b) Check low mist pressure alarm setting (Factory setting is 10 inches H
2
O / 25 m BAR
c) Check high mist pressure alarm setting (Factory setting is 30 inches H
2
O / 75 m BAR
Low pressure may indicate a leak in system, reclassifiers removed from the system or
broken lines.
High pressure may indicate plugged mist fittings of an open bypass valve.
Surging pressure may indicate an oil pocket in the distribution header or inlet air pressure
not constant.
d) Check regulated air pressure and the supply air pressure. This regulated air pressure is
preset and should not be adjusted to regulate mist header pressure.
Generator will not operate properly below 10 PSIG - 0.7 BAR regulated air pressure.
Supply air pressure should be approximately 20 PSIG – 1.5 BAR) above the regulated air
pressure.
e) Check for proper air temperature setting (Factory setting is 120
°
F - 49
°
C).
f) Check oil level in the main generator reservoir.
g) Check general unit condition for leaks, broken gauges, etc. and repair as needed.
2) WEEKLY CHECKS
a) Check all control and alarm set points.
b) Clean inside of generator console and correct any leaks.
3) MAINTENANCE CHECKS
The following maintenance procedures should be performed at least on a semi-annual basis
to help insure proper system operation. If your “IVT” is installed in an extremely dusty or
humid environment or if you are concerned about the quality of your compressed air supply,
the maintenance schedule should be accelerated. Consult with the nearest manufacturing
office/service center for further discussion and recommendations.
a) Change oil filter element (P/N 77-500-487).
