摘要
针对疏浚作业中输送系统工作效率和经济性随工况变化会出现较大波动的问题,分析土质、排距、管径、输送浓度等因素的可施工范围及临界流速、汽蚀余量对系统工作范围的限制,研究输送浓度变化引起的系统产量和效率变化规律,并就典型案例给出了特定工作条件下优化施工的方法,供施工人员参考。
In view of the sharp fluctuation in efficiency and economy of slurry transportation by pipeline, we analyze the ranges of particle size, transportation distance, pipe diameter, delivery concentration and the restriction of critical velocity and net positive suction head （NPSH）, study the change laws of efficiency and economy of slurry transportation system caused by the change of transportation concentration, and propose the optimal construction method under specific working condition.
