REGULAR MAINTENANCE
A well-designed maintenance program will add
years of service to the booster.
Check a newly installed booster frequently during
the first month of operation, especially lubrication.
With the booster at rest, check the oil level in both
the gear (drive) end and free (non-drive) end of
the booster and add oil as needed. Complete oil
changes are recommended every 1,000 – 1,200
operating hours, or more frequently depending on
the type of oil and operating temperature. Boosters
with mechanical seals on the rotors can generally
run the full 1,500 hours before an oil change is
required. Also change the oil more frequently if
pumping corrosive vapors or where excessive
operating temperatures are encountered.
The following is recommended as a minimum
maintenance program.
DAILY
WEEKLY
MONTHLY
1. Check and maintain oil
level, and add oil as
necessary.
2. Check for unusual
noise or vibration (
See
Troubleshooting on
page 29
).
1. Clean all air filters. A clogged
air filter can seriously affect the
efficiency of the booster and cause
overheating and oil usage.
2. Check the relief valve to make sure
it is operating properly.
1. Inspect the entire system for leaks.
2. Inspect the condition of the oil and
change if necessary.
3. Check drive belt tension and
tighten if necessary.
Oil levels should be checked every 24 hours of
operation.
Proper oil drain schedules require oil be changed
before the contaminant load becomes so great
that the lubricating function of the oil is impaired
or heavy disposition of suspended contaminants
occurs. To check the condition of the oil, drain a
sample into a clean container and check for the
presence of water or solids. Slight discoloration of
the oil should not necessitate an oil change.
SPARE PARTS
Should adjustments or replacement be needed,
repairs can often be performed locally as described
in this manual after obtaining the required parts.
Personnel should have a good background of
mechanical experience and be thoroughly familiar
with the procedures outlined in this manual. For
major repairs not covered in this manual, contact
the nearest Tuthill Vacuum & Blower Systems
service representative.
When ordering parts, supply the booster nameplate
information, as well as the item number and parts
description as per the parts lists and assembly
drawings. Repair kits are available for all models.
These kits contain all the seals, bearings, O-rings,
locks, and special retaining screws necessary for
an overhaul. For convenience when ordering parts,
complete the
Operating Data Form
included on
the inside, back cover of this manual.
In developing a stock of spare parts, consider the
following factors:
• The degree of importance in maintaining the
booster in a “ready” condition
• The time lag in parts procurement
• Cost
• Shelf life (seals and O-rings)
