在充填料浆的输送过程中,充填管路接头起着至关重要的作用。某煤矿超高水材料充填开采过程中,前期使用的混合管与充填软管的简易接头因其诸多缺陷,在工作过程中易被堵塞。为此,对四通接头进行改进设计,并从流体力学的角度分析了它的性能。实践证明,该设计改进效果良好,解决了以前存在的诸多问题。 Filling pipe joints play a crucial role in the transfer of the filler slurry. In a coal mine ultra-high water material filling and mining process, the pre-mixed pipe and filling hose simple joints due to many defects, easy to be blocked in the course of their work. To this end, the four-way joint to improve the design, and from the fluid mechanics point of view of its performance. Practice has proved that the design improvement effect is good, to solve the many problems that existed before.
