1, the common faults

1.1 belt conveyor belt did not turn

Belt conveyor drive roller idler belt skid after motor starting, starting up belt conveyor belt, the fault is due to the belt conveyer belt tension is not enough, out of tension device, the belt is too long, overloading starting, belt conveyor belt conveyor belt tail pile of coal causes such as much.

1.2 belt conveyor belt running deviation

Belt conveyor running deviation reason is in the operation of the belt conveyor belt in a transverse force, causes of transverse force has the following kinds: conveyor eccentric loading and side, rather than in the center of the belt conveyor; Belt conveyor rollers and roller axis installation and not vertical belt conveyer belt centre; Belt conveyor body wire rope and inconsistent; Conveyor belt joint is not straight, straight; Out of coal unloading roller position; Out of the tail roller, guide roller can cause the belt running deviation.

The wandering are generally in the running of the belt conveyor belt, adjustment should pay attention to when the belt running direction, the direction and wandering if the belt running deviation, and to the right place just at the beginning of the belt deviation along the belt conveyor belt running direction roller shaft end right, or down the mobile belt conveyor roller in the direction of the left end, make the roller left slightly lean forward, adjust to more than a few roller, when each roller to adjust less, large amount of adjustment of the belt will be wandering in the other direction, the belt conveyer belt adjust method when left as mentioned above, just adjust the direction; Belt conveyor belt running deviation if happen at the end of guide roller, roller, uninstall the drum, adjustable head frame, the tail frame on the iron and bolt, before the adjustment bolts on both ends of the drum shaft to relax some benefit adjustment, adjusted to tighten, roller for wandering.

1.3 the belt conveyor belt easily broken

This reason is composed of belt tension is too large, joint is not strong, poor quality of belt buckle, belt with long time \ maintenance caused by the poor quality, method is the tight tension device, reduce the tension in a timely manner to replace a new belt, strengthen the maintenance quality.

1.4 belt conveyor speed reducer abnormal sound

Belt conveyor speed reducer abnormal voice is excessive wear by bearing and gear clearance is too large or shell stability caused by the screw loose, treatment method is to replace the bearing, adjust the gap to repair or replace the whole reducer.

1.5 belt conveyor speed reducer heat up too fast

The reason is because of too much oil, poor heat dissipation performance, speed reducer, buried in coal source, processing method is to adjust oil and remove the source of coal.

1.6 belt conveyor speed reducer leakage

Reason is sealing ring damage, reducer box body combined with surface uneven, counterpart bolt is not tight, treatment method is to replace the sealing ring, tighten body joint surface and the bearing cap bolts.

1.7 belt conveyor rollers did not turn

The reason is that roller bearing damage, the rollers on both sides of the sealing ring in the pulverized coal, block does not turn, make the supporting roller bending stress is too large. Processing method is to replace the roller shaft repair, reducing the goods point of difference, or can use shock the goods point of roller.

2, prevention measures of belt conveyer common faults

(1) to guarantee the normal work of the belt conveyor, in addition to the general daily maintenance, daily check also note belt conveyor, belt conveyor, preventive maintenance to improve the quality of repair and maintenance.

(2) to improve maintenance personnel of the professional knowledge, correct belt conveyor operation, ensure the stable operation of the belt conveyor.
