Table 3-1 Recommended Maintenance & Frequency
Equipment
Recommended Maintenance Recommended
Interval
Exhaust
Stacks Check the exhaust stacks, after 6 months of operation, for possible buildup
of materials generated from firing processes.
The stacks should be cleaned, as necessary, with a brush and solvent to
remove the buildup. A periodic inspection of the stacks is essential to
establish a sensible maintenance cycle, since some processes will require
frequent cleaning, and others require none at all.
After the first
6 months,
and
thereafter as
required.
Lamp
Heating
Elements No maintenance is required for the heating elements other than replacement
when one burns out. Note that with low temperature operations, the lifetime
of the heating element is in excess of 100,000 hours. It is only at
temperatures in the 900°C to 1000°C range that the expected lifetime begins
to shorten. Also, the heating elements do not degrade over time. Should
failure occur, it will be sudden and catastrophic. Use ohmmeter for best
results visual inspection is unreliable. Refer to the Reference Manual for
changing heating elements. Inspect
regularly,
replace
lamps as
required.
Lamp Seals Inspect the lamp seals for loose, cracked or missing packing material. Once
the side covers are removed, the lamp seals can be visually inspected. 6 months
Sprocket
Alignment The sprockets are contained in the motor enclosure at the exit end of the
oven. Visually verify that the sprockets are aligned. Adjust according to the
furnace Reference Manual, Chapter 7. After first 30
days and
annually
thereafter.
Sprocket
Shaft
Bearing
Block The sprockets are contained in the motor enclosure at the exit end of the
oven. The sprocket shaft bearing block is equipped with a grease fitting for
lubrication. The bearing block should be lubricated with a general
multipurpose bearing grease. Apply enough grease to the bearing block so
that excess grease can be visually seen squirting out along the shaft of the
device. Wipe off all excess grease that has squirted out to avoid dirt
accumulation. 6 months
Transport
Belt Length Check the length of the transport belt and shorten it if the gravity loop comes
within 6 inches of the floor. A properly shortened belt should hang between
2 and 3 inches below the main frame.
Annually, or
as required.
Transport
Clutch The clutch should be inspected periodically to insure proper tension on the
belt. To adjust, a large hex nut at the chain sprocket end of the drive drum
must be tightened until the drum turns. If the drum cannot be stopped by
firm pressure with your hands, the clutch is too tight. Do not over tighten the
clutch, as it is there for safety reasons. Annually, or
as required
