| 管带机正常运行时进行认真巡检和必要的及时调整是防范输送带翻带的重要措施之一。另外，还必须进行一些改造： Careful inspection and necessary timely adjustment of the belt conveyor during normal operation are one of the important measures to prevent belt turnover. In addition, some improvements must be made: 1、机尾导料槽安装限流板。瞬时流量不大于300t/h是管带机正常运行的必要条件。上述原因分析时说到瞬时流量有达到400t/h的情况，这是造成胀管，并可能导致翻带的重要原因。避免瞬时超大流量的煤进入管带机，除加强协调、监督外，进行必要的改进是积极的。为此，在机尾导料槽出口处安装了限流板。限流板的流通面积需经过多次试验才能确定，如果小了，影响到正常运输；如果大了，就失去了限流的作用。安装限流板后，消除一个重大隐患，达到了预期效果。 1. The tail guide trough is equipped with a current limiting plate. Instantaneous flow rate not more than 300 t/h is a necessary condition for the normal operation of the belt conveyor. In the analysis of the above reasons, it is said that the instantaneous flow rate reaches 400 t/h, which is an important reason for tube expansion and may lead to rollover. In addition to strengthening coordination and supervision, it is positive to make necessary improvements to avoid the instantaneous and super-large flow of coal entering the belt conveyor. For this reason, a current limiting plate is installed at the outlet of the tail guide groove. The flow area of the current limiting plate can be determined by many tests. If it is small, it will affect the normal transportation; if it is large, it will lose the function of current limiting. After installing the current limiting plate, a major hidden danger is eliminated and the expected effect is achieved. |
