Mechanical breakdown |
Reason |
Solution |
|
V-belt heat |
-
V-belt loose
-
Through of belt is broken or the surface is rough
|
-
Loose the bolt for fasten the motor, adjust the distance between motor and belt pulley
-
Check and repair the belt pulley
|
|
Bearing heat |
-
The grease is excessive or shortage or the quality is bad
-
Bearing is broken
-
Main shaft bend or the inertial force is not balanced
-
The bearing cup is not compact with other part
-
Belt too tight
-
Work under overload long time
|
-
Change the grease
-
Change bearing
-
Correct the main shaft
-
Change the part which coordinate with the bearing
-
Adjust the tightness of the V-belt
-
Reduce the feeding rate
|
|
There is no force for motor |
-
Two phase electricity
-
Circle short for the winding
-
Work under overload long time
|
-
Get through the lost phase electricity, let is run under 3 phase
-
Inspection the motor
-
Let equipment work under rated load
|
|
Hard to start for the motor |
-
Low voltage
-
Electrical wire is too thin
-
Fuse is broken
|
-
Start equipment after electricity is normal
-
Change the electrical wire
-
Change the proper fuse
|
|
Violent vibration or wiggly vibration for the screen |
-
The rotation shaft bend
-
Bearing is broken
|
1、Renew or correct the shaft、
2、Renew the bearing |
|
The un-request size material in the finished material |
-
Screen mesh is broken
-
Screen cover or seal bar is loose
|
-
Renew the screen mesh or repair the hold on the mesh
-
Press the cover and seal bar
|
|
Capacity decline |
-
The moisture is too high, block the mesh
-
The opening size is not suitable
-
Rotation speed is low or the V-belt is loose
-
Feeding rate is low
-
The rubber ball is worn out
|
-
Reduce the moisture of material
-
Renew the screen mesh
-
Check the belt pulley，the tightness of the belt
-
Increase the feeding rate
-
Renew the feeding rate
|
