| 摘 要： | 通过对钨尾矿性质、浆体颗粒悬浮机理、非均质悬液淤积流速、磨阻损失、磨损机理研究分析,设定该钨矿尾矿浆体以紊流流态输送,速度区间为2~2.5 m/s,最大输送压力为40 kg/cm2。在管道磨蚀控制、输送泵配置、检测仪器配置等方面,工程设计中注入了诸多相应技术措施。实际运转证明,输送系统运行安全、稳定,达到了设计预期目标。

| Abstract: | Based on the analysis of properties of tungsten tailings, mechanism of particle suspension in slurry, sediment velocity of heterogeneous suspension, friction loss and wear mechanism, an experiment was conducted for a kind of tungsten tailings slurry transported in a state of turbulence at the velocity of 2~2.5 m/s, with the maximum transporting pressure at 40 kg/cm2. For the engineering design, some corresponding technical measures were taken in terms of pipe wear control, arrangement of transportation pumps and detectors. The practice verified that such transportation system was safe and stable, up to the designing expectation. |
