矿山主井计量斗的故障主要有由于装矿时的冲砸与放矿时的泄流而磨损;有时也因装矿容积失控或装矿量反映不准而造成超载,引起计量斗位移,闸门受卡变形;斗内有杂物阻塞闸门复位或者气动系统出现故障影响闸门开关动作等。这些情况,均需在现场维修处理。多年来,我矿主井计量斗现场维修,坚持采用下述工作程序,保证了安全生产。
Mines main shaft measuring hopper failures mainly due to loading when the impact of mining and ore discharge when the leakage and wear; sometimes due to uncontrolled ore loading volume or charge is not allowed to reflect the cause of overloading, causing the measurement hopper displacement, gate Deformation by the card; there are debris in the bucket obstruction gate reset or pneumatic system failure affect the gate switch action. These conditions, all need to be repaired in the field. Over the years, mine mine shaft metering bucket on-site maintenance, adhere to the following procedures, to ensure safety in production.
