附录： 外文资料与中文翻译 外文资料： Common Fault Analysis For Belt Conveyer Ir. G. Lodewijks, Delft University of Technology, The Netherlands Belt conveyers as continuous bulk material conveying machinery have been widely used in the world, electric power plants, metallurgical industry and? foodstuff industry as well as in bulk material conveying machinery such as ship loader and bucket-wheel stacker-reclaimer. In the purchase, design, manufacture, erection and operation of this kind of equipment, some of new users are not familiar with them. Common fault causes and their handling methods of this kind of equipment are analyzed and described herein as a matter of experience in the past years and from the point of view of users. 1. Handling of belt deviation of belt conveyer: The belt deviation of belt conveyer during operation is the most common fault. To handle this type of fault, emphasis should be placed on the dimensional accuracy of erection and the routine maintenance. There are several kinds of causes. The differential treatment should be made according to the different causes. 1.1?? Adjustment of carrying roller set: If the belt of belt conveyer is deviated in the middle of the whole belt conveyer, the position of carrying roller set is adjusted. During the manufacture, the mounting holes on both sides of carrying roller set are machined to slots for the convenience of adjustment. For the specific adjusting methods, see Fig. 1. The specific method is that when the belt is deviated from the side, that side of carrying roller set should be moved forwards the direction of travel, or the other side moved backward the direction of travel. If the belt is deviated from the upper direction as shown in Fig. 1, the bottom position of carrying roller set should be moved to the left side and the upper position of carrying roller set is moved to the right side. ? 1.2 Installation of self-aligning carrying roller set: There are many types of self-aligning carrying roller sets such
