|
1) |
Remove
old belt. |
|
2) |
Check
for excessive wear on all of the supports. |
|
3) |
Check
for any misalignment. |
|
4) |
Remove
any residue or product build-up. |
|
5) |
Check
the end drums and pressure rolls for alignment and wear. |
|
6) |
Check
along the entire length of the conveying surface making sure it is level
and square. |
|
7) |
Install
the new belt. Use a cable attached to a leader to pull the new belt through
or attach the new belt to the old belt to pull it through. |
|
8) |
Make
sure that all the belt spirals are seated properly, if not make the necessary
adjustments. |
|
9) |
When
the new belt is pulled through the furnace / conveyor, join the two ends
together. |
| 10) |
Tension
the belt and start the drive system. Run the belt under cold condition
to make sure that the belt tracks properly. |
| 11) |
Once
the belt is tracking properly, bring the furnace / oven up to 300ºF
over one complete cycle. Stress relief the belt by running it at this temperature
for approximately two more complete cycles. |
| 12) |
Repeat
this process, increasing the furnace / oven temperature in increments of
300ºF and stress relieving it until the furnace / oven has been reached
its operating temperature. |
| 13) |
Once
the furnace / oven has reached its operating temperature, let the belt
cycle two to three times before applying load. This process will pre-oxidize
the belt. |
| 14) |
Now
the belt is ready to accept load. Make sure, especially in its early stages,
that the belt is monitored for proper tracking. |
