Deviation handling belt conveyor belt conveyor belt when the belt is running deviation is the most common failures. To address these failures, we should focus attention to the size of installation accuracy and routine maintenance. There are several reasons for deviation is required depending on the reason for different treatment.
1, adjusting the carrying idlers of belt conveyor belt conveyor belt across the middle of deviation when the adjustable roller to adjust the position of group deviation; in manufacture roller group are processed on both sides of mounting holes grow holes for adjustment. The specific method is biased towards belt which side of the roller group toward which side of the belt forward direction or the other side after the shift. Belt idler upward direction deviation is located at the Group's next move should be to the left, the upper roller group at right.
2, install the self-aligning idler group of self-aligning idler group, the middle of many types, such as shaft type, four-link, vertical roll, etc. The principle is used to block or roller rotate in the horizontal direction within a block or generate horizontal thrust so belt automatically adjust the belt wandering heart to reach the purpose. The total length is generally shorter when the conveyor belt or belt conveyor using this method, two-way run-time is more reasonable, because a shorter belt conveyor easier to deviation and not difficult to adjust. And long belt conveyor is better not use this method because the self-aligning roller group life belt use would have some impact.
3, adjusting the drive pulley and the position of drive pulley bend pulley bend pulley is adjusted with the belt deviation adjustment exercise. Because of a conveyor belt at least 2-5 roll, all the rollers are installed to be perpendicular to the direction of the centerline length of the belt conveyor, if the skew is too large deviation bound to happen. The adjustment method and adjustment of roller group is similar. For the belt to the drum head, drum, such as the right side of deviation, then the right side of the bearing seat should be moved forward, belts, deviation to the left side of rollers, then the left side of the bearing seat should be moved forward, the corresponding can also be After the shift to the left or right side bearing bearing after the shift. Rear roller adjustment methods and the head drum the opposite. After repeated adjustments until the belt transferred to a more ideal position. Drivers or bend pulley in adjusting the best pre-install its exact location.
4, tension adjustment at the adjustment of belt tension at Deviation conveyor belt adjustment is a very important link. Tension at the top of the two heavy hammer bend pulley exception of the vertical length of the belt should be perpendicular to the direction of gravity away from the vertical, that is, to ensure the level of its axle center line. Using spiral tensioning or hydraulic cylinder tensioning, the tension roller bearing should be accompanied by two translations, in order to ensure cylinder perpendicular to the axis and the vertical belt. The belt deviation of the specific adjustment method, and the roller at a similar adjustment.
5, reproduced point blanking position on the belt deviation of reproduced materials blanking point position on the belt deviation has a very big impact, particularly in the two belt conveyor in the horizontal plane perpendicular to the projection into a greater impact. Generally reproduced the point should be considered the upper and lower relative height of two belt machine. Relative height was lower, the material the greater the horizontal velocity component, the lower the greater the impact of the lateral belt, while the middle of materials is difficult. So that the material in the belt deflection on the cross-section, eventually leading to belt deviation. If the material side to the right, then the belt deviation to the left and vice versa. In the design process should be as much as possible to increase the relative height of two belt machine. In the space-limited mobile bulk transport machinery of the upper and lower funnel, leads trough the form and size of such pieces should be seriously considered. A general guide for the width of the trough belt width should be about two-thirds more appropriate. In order to reduce or avoid the belt deviation increase the blocking plate blocking material is expected to change the direction and location of the whereabouts of the materials.
6, two-way conveyor belt to run a two-way adjustment of deviation of the belt conveyor belt running the adjustment Deviation deviation than a one-way conveyor belt adjustment is relatively difficult to many, in particular when the first adjustment to adjust a certain direction, and then adjust the other one direction. Adjustment should be carefully observed the direction of belt movement and the relationship between the trend deviation, one by one to adjust. Emphasis should be placed on drive rollers and the adjustment of the bend pulley, followed by the adjustment of rollers and the material blanking point adjustment. At the same time should be noted that in the vulcanized belt to belt section length of the connector should be the direction of force on a uniform, when the introduction of lead-chain traction on both sides of the same force as much as possible.
