摘　　要：随着红土镍矿不断开发,对于低品位的镍矿采用高压酸浸绿色低成本技术逐步得到大规模推广,但如何实现高产、低耗控制,关键设备高运行率是前提条件,在湿法冶金高压浸出中关键设备高压釜隔膜泵的过流件寿命是直接影响产能和成本重要因素。本文介绍了现行的设备设计、运行、维护、改进等方面技术,对比了不同工况、不同材质等情况下过流件寿命,为后续红土镍矿项目设备选型及维护、改进提供了重要参考意义。With the continuous development of laterite nickel ore,the use of high-pressure acid leaching green and low-cost technology for low-grade nickel ore is gradually being promoted on a large scale.How-ever,how to achieve high production and low consumption control is a prerequisite for high operating rate of key equipment.In the high-pressure leaching of hydrometallurgy,the service life of the flow compo-nents of the key equipment high-pressure reactor diaphragm pump is an important factor that directly af-fects production capacity and cost.This article introduces the current technology in equipment design,operation,maintenance,and improvement,and compares the lifespan of overcurrent components under different working conditions and materials.It provides important reference significance for equipment se-lection,maintenance,and improvement in subsequent laterite nickel mining projects.
