<span class="headline-text">工作原理</span> </h3><p> </p><p> 当离心泵启动后，泵轴带动叶轮一起作高速旋转运动，迫使预先充灌在叶片间液体旋转，在惯性离心力的作用下，液体自叶轮中心向外周作径向运动。液体在流经叶轮的运动过程获得了能量，静压能增高，流速增大。当液体离开叶轮进入泵壳后，由于壳内流道逐渐扩大而减速，部分动能转化为静压能�?后沿切向流入排出管路。所以蜗形泵壳不仅是汇集由叶轮流出液体的部件，而且又是一个转能装置。当液体自叶轮中心甩向外周的同时，叶轮中心形成低压区，在贮槽液面与叶轮中心总势能差的作用下，致使液体被吸进叶轮中心。依靠叶轮的不断运转，液体便连续地被吸入和排出。液体在离心泵中获得的机械能�?终表现为静压能的提高。需要强调指出的是，若在离心泵启动前没向泵壳内灌满被输送的液体，由于空气密度低，叶轮旋转后产生的离心力小，叶轮中心区不足以形成吸入贮槽内液体的低压，因而虽启动离心泵也不能输送液体。这表明离心泵无自吸能力，此现象称为气缚。吸入管路安装单向底阀是为了防止启动前灌入泵壳内的液体从壳内流出。空气从吸入管道进到泵壳中都会造成气缚�
