长距离输送条件下的渣浆泵优化选型

Optimized Selection of Slurry Pump under Long Distance Conveying Conditions

金属矿山选矿和充填作业需要各种类型的渣浆泵,其选型是否合理直接关系到在实际使用过程中能否达到设计的料浆输送要求以及后续维修工作量。本文分别计算了某矿尾砂料浆输送的当量管路长度、管路沿程阻力系数、清水扬程及临界流速等参数,并重新进行渣浆泵的选型,以减少现有渣浆泵过流部件磨损大、检修频繁等问题。

Various types of slurry pumps are required for metal ore beneficiation and filling operations. Whether the selection is reasonable or not is directly related to whether the designed slurry transportation requirements and subsequent maintenance workload can be achieved in the actual use process. In this paper, the equivalent pipeline length, pipeline resistance coefficient, clear water head and critical flow rate of mine tailings slurry are calculated, and the slurry pump is re-selected to reduce the existing slurry pump problems such as large wear of overcurrent components and frequent maintenance.
