汾西矿业介休选煤厂是20世纪70年代投产的中央型选煤厂,其原料煤的进厂及产品销售的出厂计量全部依靠轨道衡。该厂共有5台GGT-100型静态机械式轨道衡,使用年限都在20年以上。机械式轨道衡杠杆系统结构复杂,刀口和支撑极易磨损,影响称量精度和灵敏度,原生产厂家已不再生产备件。由于其称量速度慢,维护操作不方便,采用刻度模拟量指示,在称量过程中容易产生人为误差,且称量结果不能实现自动打印记录和远距传递,无法采用计算
Fenxi Mining Jiexiu Coal Preparation Plant is the central coal preparation plant put into operation in the 1970s. Its raw coal into the plant and the factory sales of the product sales all rely on the track scale. The plant has a total of 5 sets of GGT-100 static mechanical rail scale, the useful life of more than 20 years. Mechanical rail balance lever system structure is complex, easy to wear knife edge and support, affecting weighing accuracy and sensitivity, the original manufacturer is no longer producing spare parts. Due to its slow weighing speed, inconvenient maintenance, the use of analog scale indication in the weighing process prone to human error, and weighing results can not be achieved automatically print records and long-distance transmission, can not be calculated
