固体物料的长距离管道运输系统通常由给料站、管道(包括泵站,截料、控制、计量等设备)以及用于储存物料并进行脱水的受料站等部分组成。管道运输的一个重要特性参数是物料颗粒在紊流中的沉积速度。在水平管道中只有物料垂直向上的速度抵消了向下沉积速度,才能防止在输送过程中出现颗粒沉积。这通过含有固体物料混合液流的紊流变换运动得以实现。垂直向上速度是借助于输送物料的轴向速度而产生的。固体物料越细,其沉积 The long-distance pipeline transportation system for solid materials usually consists of feeding stations, pipelines (including pumping stations, cuttings, control and metering equipment) and receiving stations for storing materials and dewatering. An important characteristic parameter of pipeline transportation is the deposition rate of material particles in turbulent flow. In a horizontal pipe, only the vertical velocity of the material counteracts the downward deposition rate to prevent particle deposition during transport. This is achieved by a turbulent transformation movement involving a mixed stream of solids. The vertical upward speed is generated by the axial velocity of the material being conveyed. The finer the solid material, its deposition
