One. conveyor belt running deviation:
1. The deviation of the outer cylinder of the roller is too large, the roller is not straight (the straightness is out of tolerance), and the rotation is not flexible, etc., will also cause the belt running deviation.
2. The installation of roller center line is not vertical to the belt center line, and the installation of roller center line is not horizontal, which will also cause belt deviation.
3, the installation error of the belt machine tensing device and the improper tension adjustment on both sides of the conveyor belt will also cause the belt running deviation.
4, belt conveyor incoming direction, blanking position is not appropriate, will have an impact on the belt running deviation.
5, the design did not consider the use of rectifying device or rectifying device is not good.
Two. Deviation occurs near the same idler of the conveyor belt:
1. The frame is partially bent or deformed, and the bending or deformed part of the frame shall be corrected in time.
2. The idlers are not properly adjusted. Adjust the idlers.
3, roller adhesion and agglomeration, eliminate the adhesion.
4. The idler falls off, install the idler, and refueling and maintenance in time.
Three. Deviation occurs in the same part of the conveyor belt:
1, the conveyor belt joint is not properly connected, reconnect.
2, conveyor belt edge wear, hygroscopic deformation, repair the damaged parts at any time.
3, the conveyor belt body bending, using the self-aligning idler to adjust the deviation or cut the bending part to reconnect.
Four, the conveyor belt at the nose or tail deviation:
1. The center line of the driving drum and the reversing drum is not parallel, adjust the center line of the drum to make it parallel.
2, the drum adhesion is fast, eliminate the agglomeration on the drum, check whether the cleaner is effective.
Five, conveyor belt deviation in no load:
1, the conveyor belt into poor slot, then replace into a good slot conveyor belt.
2. The conveyor belt is not compliant enough, and when the deviation is corrected by the aligning idler, it is still invalid, and the conveyor belt with good compliance is replaced.
Six, the conveyor belt runs off when loading:
1. When loading, the material is on one side (single side receiving material), and the unloading groove is adjusted to make the center of the conveyor belt receive material.
2, compared with the conveyor belt width, the material diameter is too large, the material is broken or change the conveyor belt width.
Seven, conveyor belt skid:
1, the use of heavy hammer tensiondevice in the belt conveyor belt slip can be added to the weight to solve, add to the belt does not slip.
2, the use of screw tensioning or hydraulic tension belt conveyor skid can be adjusted to increase the tension stroke.
Eight, the early damage of the adhesive on the conveyor belt:
1. If the baffle plate is not properly installed, check whether the baffle plate is properly installed.
2, by large sharp Angle material impact, improve the feeding conditions, reduce the impact force of materials.
3. If the feeding speed is too fast or the feeding port is too high, reduce the feeding speed and the height of the feeding port.
Nine. Early wear of conveyor belt side:
1. Conveyor belt deviation, team conveyor belt deviation correction.
2, the conveyor belt into poor, support roller rotation is not flexible, exchange into a good groove conveyor belt.
Ten, conveyor belt core early damage:
1, by the impact of large angular materials, crushing blocks or improved discharge tank, reduce the impact of materials.
2. Block materials and foreign bodies are involved between the conveyor belt and the drum to prevent foreign bodies from falling between the conveyor belt and the drum.
3, in the discharge slot is hard hook, install metal detection or magnetic removal device.
Eleven, conveyor belt longitudinal tearing:
1. After the foreign body falls and is stuck, check whether the rack attachment is loose at any time, and correct it in time if it is loose.
2. The machine accessories are loose, the Angle iron screw falls, the baffle plate and the scraper are stuck, and the V-shaped scraper is installed at the tail wheel.
3. If the roller falls off after wear, install the suspension belt magnet separator.
4, large foreign body attached to the belt, install electrical protection or ultrasonic testing device.
Twelve, the early wear of the cover glue under the conveyor belt:
1. The conveyor belt slips on the idler, increasing the friction coefficient of the idler.
2. The bending groove idler tilts too much, which increases the tension of the conveyor belt.
3, the upper roller rotation is not good, improve the roller rotation conditions and reduce the groove roller surface slope.
4. Adhesion and agglomeration on the surface of the roller can eliminate the adhesion on the surface of the roller.
Thirteen, belt conveyor reducer broken shaft:
1. The design strength of the high-speed shaft of the reducer is not enough. In this case, the reducer should be replaced or the design of the reducer should be modified.
2. When the motor shaft and the reducer high-speed shaft have different centers, the radial load of the reducer input shaft will be increased and the bending moment on the shaft will be increased. The broken shaft phenomenon will occur in long-term operation. In most cases, the motor shaft will not break the shaft, this is because the motor shaft material is generally 45 steel, the motor shaft is coarse, the stress concentration is better, so the motor shaft is usually not broken.
Fourteen, the belt conveyor belt is easy to disconnect:
1. If the belt tension is too large, tighten the tension device to reduce the tension.
2, the joint is not firm, the belt buckle quality is poor, replace the belt buckle, reconnect.
3, the belt use time is long, timely replacement of new belt.
4, poor maintenance quality, strengthen maintenance quality.
Fifteen, the service life of the conveyor belt is short:
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 that the cleaner is reliable and easy to use when running, and there should be no material on the return belt.
2, belt manufacturing quality is one of the biggest concerns of user content, should also be considered in selected a model after its manufacturing quality, appearance can be performed on regular check, and see whether there is a crack, the aging situation, after making deposit time is too long, one of the above situation should not purchase, found in the initial cracking belt, damage often use time is shorter.
Sixteen, the belt conveyor idler does not turn:
1. The reason is that the roller bearing is damaged, and the sealing rings on both sides of the roller are blocked after the dust enters, so that the roller is stressed too much and bent. The treatment method is to replace the roller and bearing, reduce the height difference of the dropping point, or the buffer roller is used in the dropping shop.
Seventeen. Abnormal noise of belt conveyor:
1. Noise when the idler is seriously eccentric:
(1) The seamless steel pipe wall thickness of the roller is uneven, and the centrifugal force is larger.
②, is in the processing of both ends of the bearing hole center and the outer circle center deviation is large, so that the centrifugal force is too large.
2. The noise when the height end of the driving device clicks on the coupling between the reducer and the different heart.
3. When the reversing drum and the driving drum work normally, the noise is very small. When abnormal noise occurs, the bearing is generally damaged, and the bearing seat makes cackling noise.
Eighteen. Abnormal sound of belt conveyor reducer:
1. The abnormal sound of the reducer is caused by excessive wear of the bearing and gear, too large clearance or loose shell screw. The solution is to replace the bearing, adjust the clearance or replace the reducer and carry out overhaul.
Nineteen, belt conveyor reducer heating up too fast:
1. This reason is caused by excessive oil quantity, poor heat dissipation performance, and the reduction engine being buried by coal. The treatment method is to adjust the oil quantity and remove coal.
Twenty. Oil leakage of belt conveyor reducer:
1. The reason is that the sealing ring is damaged, the joint surface of the reducer box is uneven, and the opposite bolt is not tight. The treatment method is to replace the sealing ring, tighten the joint surface of the box and the bearing cover bolts.
