Belt conveyor Troubleshooting and preventive measures

A Belt Conveyor common faults and

( 1 ) conveyor belt does not turn : after starting the motor idling conveyor drive roller slip , not start up , this failure is due to insufficient belt tension , tension device is not adjusted , the conveyor belt is too long, heavy start , the conveyor belt Last heap of coal wait causes.

( 2 ) conveyor deviation : Deviation reason is in operation generating a lateral force , lateral force generated following reasons : Conveyor loading biased side , rather than mounted on the center position ; idlers and rollers installation is not perpendicular to the center axis of the conveyor ; fuselage height rope inconsistent ; conveyor belt joint straight, not straight ; unloading roller position is not adjusted ; tail rollers, guide rollers did not adjust the belt can cause deviation .

Deviation modulation are generally carried out belt conveyor operation , adjustment to the attention of the belt running direction and the deviation direction , if the belt deviation to the right , on the side where the belt starts moving in the direction along the conveyor belt rollers run Right shaft , or along the transport direction of movement of the left idler shaft , so that the left end of the roller is slightly tilted forward, the adjustment to adjust a few more rollers, each roller is less tune some , excessive adjustment belt will be in the other direction deviation, adjust the belt to the left deviation method described above, is an adjustment in the opposite direction ; belt deviation when it occurs in the guide roller , tail roller , unloading roller , adjust the headstock , tail rack side rail and bolts before adjustment bolt to loosen some of the ends of the roller shaft to facilitate adjustment Fluting machine, the adjusted to tighten , having a good deviation roller .

( 3 ) Belt Easy Disconnect: This is caused by the belt tension is too large , the joint is not solid, poor quality belt buckle , belt use for a long time , and poor quality of maintenance reasons, is to tighten the tensioning device to reduce tension replace them with new belts and strengthen the quality of maintenance .

( 4 ) Reducer abnormal sound : This is caused by excessive wear of bearings and gears gap is too large or snail shell stable Sisong moving cause, treatment is to replace the bearings, adjust gap or replace the whole gearbox overhaul .

( 5 ) excessive heating gear : This is due to too much oil , cooling performance is poor, reducer buried coal caused by the source , treatment method is to adjust the oil , remove the source of coal .

( 6 ) gear oil spill : damage due to seals , combined with uneven surface reducer casing , Counterpart bolts are not tight, approach is to replace the seals , tighten the joint surface and each box bearing cap bolts.

( 7 ) roller does not turn : The reason is roller bearing damage , roller seals on both sides into the coal , the block does not turn, so that the roller shaft bent by excessive force . Approach is to replace the rollers, and repair , reducing the loading and unloading point elevation , or loading and unloading points use shockproof Care roll .

Second, the failure to prevent belt conveyor measures

( A ) To ensure that the conveyor work, in addition to daily general repair and maintenance , but also pay attention to the daily inspection, periodic maintenance, repairs and maintenance to improve quality .

( 2 ) to improve the expertise of maintenance personnel , proper operation of belt conveyors, to ensure stable operation of the conveyor .
