在论述了固液混合流的理论发展,和结合实例阐明了理论的应用之后,本讲将介绍国内外管道输送技术的概况,以便读者了解目前该领域的概貌与发展,供选择粒状物料运输方法的参考。 (一)国内外应用管道技术的现状众所周知,最早的管道输送技术,受泵压设备扬程小的限制,只在短距离范围内运送粒料,如尾矿、泥沙、充填料、水力开采的矿砂和煤水混合物等。实践证明,它是一种有效的运输方法。随着高压杂质泵的
After discussing the theoretical development of solid-liquid mixed flow and illustrating the application of the theory in combination with examples, this lecture will introduce the general situation of pipeline transportation technology at home and abroad so that the reader can understand the current overview and development in this field and choose the granular material transportation method The reference. (A) the status quo of the application of pipeline technology at home and abroad As we all know, the earliest pipeline transportation technology, limited by the pumping head lift small, only within a short distance transport pellets, such as tailings, sediment, filling material, hydraulic mining Ore and coal water mixture. Practice has proved that it is an effective method of transportation. With high pressure impurities pump
