Run-time
belt conveyor belt running deviation is the most common fault.
In order to solve this kind of fault point is to pay attention to the size precision of installation and daily maintenance.
Run a variety of reasons, according to the different reasons for the difference between treatment to: 1. Adjust the carrying idler group.
Belt line belt in the central belt conveyor running wide adjustable roller set to adjust the position of running deviation;
When making roller set of mounting holes are processed to grow on both sides of the hole, in order to adjust.
Specific methods to which side is belt, roller group which side of the direction of the belt moved forward, backward or the other side.
Belt running deviation upward direction under the roller group, should move to the left, on the roller group located to the right.
2, install self-aligning roller group.
Self-aligning roller group has a variety of types such as intermediate shaft type, four connecting rod type, the vertical roll type etc. Its principle is to use blocking or roller rotation in the horizontal plane directions or resulted from lateral thrust belt automatically to achieve the purpose of running deviation of the belt can be adjusted.
Generally in a relatively short or the total length of the belt conveyor belt line two-way runtime USES this method is reasonable, reason is the short belt conveyor is more likely to run partial, and not easy to adjust.
The long belt conveyor had better not use this method, because the use of self-aligning roller group will produce certain effect on the service life of the belt.
3, adjust the driving drum and redirection roller position.
And the adjustment of the redirection roller driving drum is an important part of the belt running deviation adjustment.
Because of a belt conveyor are at least two to five drum, drum of all installation location must be perpendicular to the centerline of the direction of the length of the belt conveyor, if excessive deflection must be wandering.
The adjustment method and similar roller group.
To head to the right side of the drum drum, such as belt running deviation, the bearing should move forward, on the right side of the conveyor belt to the drum of the left side of the wandering, is on the left side of the bearing should be moving forward, can also be on the left side of the corresponding bearing seat back or on the right side of bearing seat back.
The tail roller adjustment method is contrary to the head roller.
After repeated adjustment until the belt to the ideal location, best before adjusting drive or redirection roller installed its position accurately.
4, zhang JinChu adjustment.
Belt of JinChu adjustment is belt conveyor running deviation of a very important link.
Two upper heavy hammer zhang JinChu redirection roller besides belt length should be perpendicular to the direction should be perpendicular to the gravity vertical, which ensure the shaft centerline.
Using spiral tension or hydraulic tensioning oil cylinder, the two tension roller bearing should translation at the same time, to ensure that the cylinder axis and the vertical belt longitudinal direction.
The specific belt running deviation adjustment method and the roller of similar.
5, two-way running of belt conveyor belt running deviation adjustment than one-way line belt running deviation of a much more difficult, in the concrete adjustment should be first in one direction, and then adjust the other direction.
Adjustment should observe carefully when belt movement direction and trend of running deviation, the relationship between one by one.
The emphasis should be on the adjustment and haul driving drum drum, followed by the adjustment of the roller and the material of blanking point adjustment.
Belt should be paid attention to and should make the belt when vulcanization joint force uniform, and the section length direction when using leading chain traction force on either side of the equal as much as possible.
