GENERAL
Regular inspection of the blower and its
installation, along with complete checks on
operating conditions, will pay dividends in added
life and usefulness. Also, service the drive per
the manufacturer’s instructions and lubricate
the coupling or check the belt drive tension. Use
thermometers and gauges to make sure blower
operating temperature and pressure remain within
allowed limits.
DANGER
!
The blower and parts may
contain hazardous media.
Assure that pump and parts are
evacuated of hazardous media
prior to servicing.
CAUTION
!
The electrical service must be isolated and
de-energized prior to maintenance. Apply
appropriate procedures to assure electrical
supply is de-energized and cannot be
inadvertently energized during maintenance.
Assure piping and product is isolated prior
to maintenance of blower. Apply appropriate
procedures to assure piping and product
is isolated and that inadvertent opening of
valves cannot occur during maintenance.
CAUTION
!
During routine maintenance, inspect and
assure that guards are in place and secure.
Pay special attention to lubrication of timing gears
and bearings according to the information in
Lubrication on page 14
.
When a blower is taken out of service, it may
require internal protection against rusting or
corrosion. The need for such protection must be
a matter of judgment based on existing conditions
as well as length of downtime. Under atmospheric
conditions producing rapid corrosion, protect the
blower immediately.
See Long-Term Storage on
page 31
.
REGULAR MAINTENANCE
A well-designed maintenance program will add
years of service to the blower.
Check a newly installed blower frequently during
the first month of operation, especially lubrication.
With the blower at rest, check the oil level in both
the gear (drive) end and free (non-drive) end of
the blower 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. 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.
