GENERAL
Regular inspection of the vacuum booster and
its installation, along with complete checks on
operating conditions, will pay dividends in added
life and usefulness. Also, service the drive
per manufacturer’s instructions and lubricate
the coupling or check belt drive tension. Use
thermometers and gauges to make sure that
booster operating temperature and pressure
remain within allowed limits.
DANGER
!
The booster 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 booster. 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.
When changing oil, be sure to reseal the drain
and fill plugs. This is especially important on
Slinger Splash Lube Series models, which
have no mechanical seals on the rotors. Air
leaks past these plugs can cause rapid loss of
oil from end covers, resulting in booster failure.
Pay special attention to lubrication of timing gears
and bearings according to the information in
Lubrication on page 14
.
When a vacuum booster 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
booster immediately.
