 With the continuous development of the national economy in many areas of the coal industry, stone production line, sand making production line used in the conveyor. Conveyor to save manpower, but also impro ve the production efficiency. The belt conveyor has long transport distances, transport capacity, the working resistance is small, easy to install and low power consumption, less wear and tear, etc..
    SPJ-800 hanging belt conveyors, for example, analysis of the belt conveyor machine daily production process of the common faults and preventive measures. SPJ-800 belt body structure for rope rack layout and mutual equality of the rope at the same level as the rack structure is simple, to save steel and easy to install, wire rope available winch replaced the old wire rope, low cost.
    1, common faults
    1.1 belt does not turn
    The drive pulley idling of the motor starter belt slip, belt start it up, this failure is due to the belt tension is not enough, the tensioning device is not adjusted, the belt is too long, heavy start, be lt tail heap of coal and other reasons caused.
    1.2 belt deviation
    Deviation reason the belt in the operation of the lateral force, a lateral force of the reasons are the following: loading of the conveyor biased towards one side, rather than packed in the middle position; to install the axis of idlers and rollers and the conveyor belt center vertical; the fuselage rope level of inconsistency; conveyor belt joint is not straight, not straight; coal unloading roller position is not adjusted; tail roller, guide roller is not adjusted can cause the belt deviation.
    Tone deviation are generally in a belt running to adjust to the attention of the belt running direction and the deviation direction, if the belt right deviation, it is biased in the belt began to move along the conveyor belt running direction of the roller right axis shaft end of the roll er left side, or along the transport direction, so the left end of the roller slightly tilted forward, the adjustment to adjust a few idlers, each idler little tune, adjust excessive belt will deviation to another direction, when the deviation of the belt to the left to adjust the method as described above is an adjustment in the opposite direction; belt deviation occurred in the guide rollers, tail drum, drum uninstall, adjustable head frame, tail rack square iron and bolts before adjustment with the roller shaft at both ends of bolts to relax in order to facilitate adjustment, adjusted to tighten, having a good deviation roller.
    1.3 belt easy disconnect
    For this reason the belt tension is too large, the connector is not solid, the poor quality belt buckle, belt use for a long time \\\\ the maintenance of the poor quality of causes, the method is to tighten the tensioning device to reduce the tension to replace them with new b elts, to enhance the quality of maintenance .
    1.4 reducer sound abnormalities
    For this reason by the excessive wear of bearings and gear gap is too large or shell stability snails worked loose action caused, the approach is to replace the bearings, adjust gap or replace the overall speed reducer for a major overhaul.
    1.5 reducer heating up too fast
    For this reason the oil too much, the poor thermal performance, the reducer is the source of coal buried result of the approach is to adjust the fuel, remove the source of coal.
    1.6 deceleration machine oil spills
    The reason is that the ring damage, combined with uneven surface deceleration box of their counterparts in the bolt is not tight, the approach is to re place the seals, tighten the box combined with the surface and the bearing cap bolts.
    1.7 roller does not turn
    The reason is that the roller bearing is damaged, the roller on both sides of the ring into the pulverized coal block will not be diverted to prop roller played Big Bend. The approach is to replace the idler shaft and repair, reducing the height difference of the loading and unloading points, or loading and unloading point of the shock prop roll.
    2, the prevention belt conveyor machine Common Faults measures
    (1) in order to guarantee conveyor belt, in addition to daily general repair and maintenance, but also pay attention to the daily checks, regular maintenance, to improve the quality of repair and maintenance.
    (2) to improve the maintenance staff\\ s expertise, the correct op eration of the conveyor belt to ensure stable operation of the conveyor.
