Cause of the accident conveyor belt run running belt run is the most common faults. Frequent deviation accident, conveyor design, will affect the life of the conveyor, a serious accident or an outage could result in personal injury or death. The main cause of belt run has three aspects: First, the device itself aspects of the outer cylindrical drum error is large, Liaoyang belt conveyors, roller rotation is not flexible, active roller and driven roller parallel to the axis the degree of error is larger; two is the installation commissioning, such as roller, roller, rack-mounted do not meet the regulatory requirements, additional vent opening position deviation coal, conveyor classification, resulting in partial load so that deviation tape; Triple the maintenance, mainly due to the cleaning is not timely, the conveyor roller roller machine Tropsch coal dust stained, resulting in local diameter ambassador belt run. Install the belt conveyor is generally carried out according to the following stages. Installation rack mounting belt conveyor frame starting from scratch, and then install the various sections in turn the intermediate frame, and finally the installation of the tailstock. Before installing a rack, first pulling on the center line of the entire length of the conveyor, because keeping the center line of the conveyor in a straight line is an important condition for the normal operation of the conveyor belt, so when you install the rack sections, must aligned with the center line, conveyor selection, but also put on airs leveling chassis centerline tolerance per meter captain of ± 0.1mm. However, the entire length of the conveyor frame center of error should not exceed 35mm. When all single install and identify after each block can be connected.
