2. Conveyor belt flexibility is not enough. After correcting the idler rollers, if it is still ineffective, the conveyor belt with good flexibility is replaced.
3, the tension on the conveyor belt is too small, increase the pre-tension.
(5) When the conveyor belt is deflected while loading:
1. When the material is loaded side by side (single side receiving material), adjust the position of the discharge chute, and make the center of the conveyor belt receive the material.
2, compared with the width of the conveyor belt, the material diameter is too large, the material is broken or change the width of the conveyor belt.
(6), conveyor belt in the head or tail deviation:
1. The centerline of the driving roller and the reversing roller is not parallel. Adjust the roller centerline to make it parallel.
2. Roller sticking block eliminates agglomeration on the roller and checks whether the cleaner is effective.
(7) Conveyor belt slipping:
1. The belt conveyor using the hammer tensioner can add counterweight when the belt slips, and it can be added to the belt without slipping.
2. When using a tensioned or hydraulically tensioned belt conveyor, it can adjust the tension stroke to increase the tension.
(8) Early damage to the covering rubber on the conveyor belt:
1. The installation of the blocking plate is not suitable. Check whether the blocking plate is installed properly.
2, by the impact of large pieces of sharp materials, improve the feed conditions, reduce the impact of the material.
3, the feed rate is too fast or the feed port is too high, reduce the feed rate and feeding port height.
(9) Early wear and tear on the conveyor belt
1, the conveyor belt skid on the roller, increase the roller friction coefficient.
2, bending roller roller tilt is too large, increase the conveyor belt tension.
3, the upper idler rotation is not working, to improve the roller rotation conditions and reduce the groove roller surface tilt.
4. Adhesion of agglomerates on the surface of the idler roller eliminates adhesion of the roller surface.
(10), the early wear of the belt edge:
1, conveyor belt deviation, the correction of the conveyor belt.
2. The groove of the conveyor belt is poor, the support roller rotation is inflexible, and the conveyor belt is replaced with a good groove.
(11), conveyor belt core early damage:
1, by the impact of large pieces of sharp materials, crushed block or improve the unloading tank, reducing the impact of the material.
2. Block material and foreign matter are caught between the conveyor belt and the roller to prevent foreign matter from falling between the conveyor belt and the roller.
3, in the unloading of the waste site is hooked by a hard object, install metal detection or magnetic removal device.
(12), conveyor belt longitudinal tear:
1. After the foreign object has fallen and the belt is stuck, check whether the rack attachment is loose at any time and correct it if loose.
2. The rack accessories are loose, the angle iron screws fall down, the baffle and the scraper are stuck, and the V-shaped scraper is installed at the tail wheel.
3, after the roller wear off, install the hanging band magnet separator.
4, large foreign objects attached to the belt, install electrical protection or ultrasonic testing device.
(13), belt conveyor belt easy to disconnect:
1, the belt tension is too large, tighten the tension device to reduce tension.
2. The connector is not firm and the quality of the belt buckle is poor. Replace the belt buckle and reconnect it.
3, the belt is used for a long time, replace the new belt in time.
4, poor maintenance quality, strengthen the quality of maintenance.
(14) The service life of the conveyor belt is shorter:
1. The service life of the belt and the use of the belt are related to the quality of the belt. The belt conveyor should ensure the reliable use of the cleaner during operation. There should be no material on the return belt.
2. The manufacturing quality of the belt is a content that the user is more concerned about. After selecting a certain model, it should also consider the manufacturing quality. The appearance inspection can be performed routinely to see if there is cracking and aging, and it is stored after manufacture. Whether the time is too long or not, one of the above situations should not be purchased, and the belt originally found to be cracked is often damaged when it is used for a relatively short period of time.
(15), belt conveyor roller does not turn:
1. The reason is that the idler bearing is damaged. After the seal ring on both sides of the idler rolls into the dust, it is blocked and not rotated, so that the roller shaft is subjected to excessive force and bending. The processing method is to replace the idler roller and the bearing and reduce the blanking point. Height difference, or blanking point using buffer roller.
(16) Abnormal noise of belt conveyor:
1. Noise when the idler is seriously decentered:
1. It is the uneven wall thickness of the seamless steel pipe used to make the roller and the centrifugal force generated is large.
2. It is during the machining that the deviation between the center of the bearing bore at both ends and the center of the outer circle is large and the centrifugal force is too large.
2. The noise of the coupling between the high-speed motor and the speed reducer of the drive device is different from that of the coupling.
3. When the reversing roller and the driving roller work normally, the noise is very small. When the abnormal noise occurs, the bearing is generally damaged, the bearing seat is rattled and the bearing needs to be replaced at this time.
(17) Broken shaft of belt conveyor reducer:
1. The high-speed shaft of the reducer is not designed with sufficient strength. In this case, the reducer or the design of the reducer should be changed.
2. When the motor shaft and the high-speed shaft of the reducer do not have the same center of mind, the input shaft of the reducer will increase the radial load, and the bending moment on the shaft will increase. The shaft breakage will occur during long-term operation. The position should be carefully adjusted during installation and maintenance. To ensure two axes are concentric. In most cases, the motor shaft will not break the shaft. This is because the material of the motor shaft is generally No. 45 steel. The motor shaft is relatively thick and the stress concentration is better, so the motor shaft will not break.
(18) The noise of the belt conveyor reducer is abnormal:
1. The noise of the reducer is caused by the excessive wear of the bearings and gears, the excessive clearance or the looseness of the housing screws. The processing method is to replace the bearings, adjust the clearance or replace the reducer, and perform the overhaul.
