Failures and approach conveyor belt

Conveyor belt Common Cause analysis and treatment of the conveyor belt can be used as the transport machinery has been widely used in coal , grain, flour mills and other

industries. Can transport bulk material ,belt conveyor design  the material can be transported in bags . Users when installing and using such equipment, often out

Now some of the belt conveyor manufacturer cause of the malfunction is not clear , not much processing methods. In this paper describes the causes and treatment of common faults such equipment . A

conveyor belt conveyor belt slippage and solutions in operation , slipping for many reasons , common causes and solutions are:

1, the initial tension is too small. Leave the tension roller conveyor at the inadequacy of the conveyor belt slippage. This situation generally occurs at startup , the solution

is to adjust the tensioning device , increasing initial tension . 2 , the friction between the drive roller and the conveyor belt is not enough cause skidding. Its not original

Mostly due to water or humid environment on a conveyor belt. The solution is to add some rosin on the end of the drum . But be careful not to hand dosing , and the application

of the blast blowing equipment to avoid personal injury . 3 , the rear roller bearing is damaged or does not turn up and down roller bearing damage does not turn too much.

Cause of the damage is too much tail drifting without timely maintenance and replacement of damaged parts or rotation is not flexible , so that increased resistance caused by

skidding. 4 , starting too fast can also form slip. At this point may slow start . Such as the use squirrel cage motor, then start jogging twice

, The slip phenomenon can be effectively overcome . 5 , the belt load is too large, more than the motor capacity will slip. The upside is that this time slipping motor plays a

protective role. Otherwise, a long time the motor will be burned. But for running it is slipping accidents. Overcome conveyor

Slipping , slipping the first to find the reason , before taking effective remedial measures . Second, the deviation and its handling conveyor belt conveyor belt running

operation is one of the most common faults . There are many reasons for deviation , the main reason is to install low precision and routine maintenance

Poor maintenance . During installation , between the head and tail rollers , the intermediate roller on the same center line as possible , parallel to each other and to ensure

that the belt is not biased or less biased. In addition, the strap connector to the right, should be the same on both sides of the perimeter . During use , if there is deviation

, they have to make in order to

Check to determine the reason for adjustment . Conveyor deviation always check the location and processing methods are: 1, check the lateral misalignment roller conveyor belt

centerline longitudinal centerline . If the values ??do not coincide more than 3mm, you should use both sides of the elongated idlers Ann

Mounting hole to be adjusted . The specific method is biased on which side of the conveyor belt , which the lateral direction of the conveyor belt idlers advancing forward, or

the other side of the shift. 2, check the head , tail rack-mounted bearing deviation of two planes values. If the deviation is greater than two planes 1mm, then respond

Adjusting the two planes in the same plane . Adjustment of the head drum is : If the conveyor roller deviation to the right , then the right side of the roller bearing should

move forward or left bearing setback ; If the conveyor roller deviation to the left , then the left side of the roller bearing should move forward

Or after the shift to the right bearing . Rear roller adjustment method and the head drum opposite. 3, check the position of the material on the conveyor belt . Material is not

centered on the conveyor cross-section , will lead to the conveyor belt deviation. If the material is biased to the right, then the belt deviation to the left , and vice versa

Ran . In should be used as much as possible so that the material in the middle. To reduce or avoid such blocking plate conveyor deviation increase , change direction and

position of the material.
