|
malfunction
|
causes
|
eliminating methods
|
|
axis jump
|
① Blade position too low
|
Lift up the blade
|
|
② Blade gap too wide
|
Loose bolts at the side of roller seat,advance single roller seat to needed gap
|
|
|
thick and thin end（peels in section
shape）
|
① uneven blade gap at two ends
|
Advance it when gap larger and pull it back when gap smaller to get needed gap.
|
|
② Different blade height at two ends
|
Re-measure the blade height, the lift up or lower it at the theoretical
position(100mm below double roller)
|
|
|
③different gap in blade seat
|
Turn transmission gear, advance it if gap bigger and back when gap smaller.
|
|
|
Peel rolling canister
|
small gap between single and double rollers
|
Remove one or two layers of sheet iron between single roller seat and blade seat ( increase the gap)
|
|
rotary blade too high
|
slightly lower the blade height
|
|
|
Blade gap too small
|
Increase the gap of blade and single roller
|
|
|
Poor smooth peels
|
rotary cut blade too low
|
Slightly raise blade height
|
|
Too big of blade gap
|
Adjust the gap to smaller
|
|
|
non-sharp rotary cut
blade
|
use oil stone to grind edge of knife for
times or change a new one
|
|
|
Un-equality of peels thickness
|
1 Not Proper blade gap
2 Single roller bearing broken
|
Adjust the gap from the standard blade height according to peels thickness Replace single roller bearing
|
|
Asbestos appears
at peels ends
|
large blade gap in middle and small gap at ends
|
non-straight blade, concave in middle, blade need to be re-grinded
|
|
knob in the middle
of peels
|
Too small blade gap in middle and large at two ends
|
non-straight blade, knob in middle. Blade need to be re-grinded
|
|
Scratches between
guiding shaft and guiding seat
|
Poor lubrication,lack of oil
|
Add lubrication oil or change a new guiding shaft and guiding seat
|
|
Poor activity of AC
contactor
|
Voltage too low I
|
Increase capacitance, increase voltage
