摘　　要：渣浆泵作为选矿和冶炼过程中的关键设备,尤其在有色金属(主要是铜矿)的提炼过程中,其效率和耐用性直接影响到生产成本和产量。本文深入探讨了渣浆泵的磨损机制,尤其是研究其叶轮和泵壳在不同操作条件下的磨损行为。通过收集和分析真实操作数据,本文揭示了操作参数(如流速、浆体密度和固体颗粒大小)对磨损率的具体影响。在此基础上,本文提出了一系列技术改进措施和维护策略,以显著延长渣浆泵的使用寿命。这些措施包括采用新型耐磨材料、优化泵的设计参数和实施定期维护计划。实验证明,这些改进能够使渣浆泵的平均无故障运行时间提高30%,从而为选矿和冶炼行业带来显著的经济效益。As a key equipment in mineral processing and smelting processes,especially in the extraction of non-ferrous metals(mainly copper mines),the efficiency and durability of slurry pumps directly affect production costs and output.This article delves into the wear mechanism of slurry pumps,particularly studying the wear behavior of their impellers and pump casings under different operating conditions.By collecting and analyzing real operational data,this article reveals the specific effects of operational parameters such as flow rate,slurry density,and solid particle size on wear rate.On this basis,this article proposes a series of technical improvement measures and maintenance strategies to significantly extend the service life of slurry pumps.These measures include adopting new wear-resistant materials,optimizing pump design parameters,and implementing regular maintenance plans.Experimental results have shown that these improvements can increase the average trouble free operation time of slurry pumps by 30%,thereby bringing significant economic benefits to the mineral processing and smelting industries.
