输送机胶带特别是在露天采场和采石场这样极端的作业条件下,是费用高昂的易损件。用户的目标是降低与磨损有关的胶带修理和更换的费用。一种可能的方法是事先决定何时更换胶带最合适。如果能够准确地描述胶带的运行情况和操作条件,就可能做到这一点。为此,根据作业统计数字建立了一种比较简单的功能模型。使用这种模型决定的胶带故障率尽管有上升的趋势,但证实预防性更换胶带是完全合理的。如果输送机系统运行时间足够长(实际情况基本如此),那么可望预防性更换胶带会对生产费用产生积极的影响。 Conveyor belts are costly consumables, especially under extreme operating conditions such as open pit mining and quarrying. The user’s goal is to reduce the cost of repair and replacement of the tape associated with wear. One possible way is to decide in advance when it is best to change the tape. This can be done if the tape runs and operating conditions are accurately described. To this end, according to the operation statistics to establish a relatively simple functional model. Tape failure rates determined using this model, despite a rising trend, confirm the complete justification for preventive tape replacement. If the conveyor system is running long enough (as is the case in practice), it can be expected that the preventive tape change will have a positive impact on production costs.
