摘要
重钢西昌矿业有限公司1000万吨/年钒钛磁铁矿采选扩建工程——尾矿输送系统配套三套大型活塞隔膜泵设备,该装备进出口压力差较大。隔膜泵长时间运行,锥形阀出现磨损,导致矿浆从高压区泄漏至低压区,影响隔膜泵正常运行。利用锥形阀泄漏故障监测系统技术,设计一种触发报警系统,该系统通过数据采集、计算和分析,在数据异常时触发报警系统,让操作人员及时、精确判断锥形阀泄漏故障,从而有效避免因故障发现不及时而导致隔膜泵锥形阀及箱体被射穿的严重事故,进一步提高设备生产效率。
There are three sets of large piston diaphragm pump equipment for tailings conveying system of the 10 million tons/year vanadium titanium magnetite mining expansion project of Xichang Mining Co.,Ltd.,and there is a big difference between import and export pressure values of the equipment.These diaphragm pumps underwent long-time operations,and the conical valves got worn,resulting in pulp leakage from the high pressure area to the low pressure area and affecting normal operation of the diaphragm pumps.This paper employs leakage fault monitoring system of conical valve to design an alarming system.Through data acquisition,calculation and analysis,the system triggers the alarm when the data is abnormal,so that personnel can identify conical valve leakage fault timely and accurately.This helps to effectively avoid serious accidents of shoot-through of valve conical valve and tank body due to delayed fault discovery,and to further improve production efficiency of equipment.
