渣浆泵选型
在选煤厂生产实践中,渣浆泵不仅被广泛地用于煤泥水、循环水、煤浆以及重介质悬浮液等流体的输送作业,而且.在作为分级浓缩)旋流器、重介(水介)分选旋流器、压滤机的入料泵使用时,还直接影响到工艺指标。因此,作为选煤厂的重要辅助没备,其运转好坏直接影响生产系统的正常运行。
选煤厂使用zui多的是ZJ系列渣浆泵和AH、ST系列渣浆泵。其中ZJ系列渣浆泵是我国自主开发的产品,AH、ST系列渣浆泵引进的是沃曼泵技术。
渣浆泵工作原理
渣浆泵属于离心式水泵。渣浆泵工作原理如图1-1所示。渣浆泵的外壳容器是静止不动的,而外壳内的叶轮由电动机带动高速旋转;叶轮转动产生的离心力作用于液体,将充满于叶轮之间槽道中的液体从叶轮中心甩向四周,并抛人泵壳内,使液体获得动能和压能;由于叶轮外围的泵壳断面是不断加大的,故液体的动能部分地转化为压能,因而水泵出口处的液体具有较大的压力,可以通过排水管道把液体排送到一定的高度和距离。另外,在液体从叶轮中心甩向四周的同时,叶轮进口处形成低压带(具有一定真空度),液池中的液体在大气压力作用下,通过滤网经吸入管而进入叶轮内,以补充从叶轮中流出的液体量。叶轮不断地旋转,使液体获得离心力,液体就不断地被吸人和压出,这样,离心泵就*地向外输水。
渣浆泵结构图及结构型式
选煤厂常用的渣浆泵分为卧式轴向吸人单级单吸离心式渣浆泵和立式轴向吸人单级单吸渣浆泵两大类,尽管型号众多,但其结构型式大同小异。常用卧式渣浆泵见图1—2,立式渣浆泵见图l-3。
