离心泵

1、离心泵的工作原理

水泵开动前，先将泵和进水管灌满水，水泵运转后，在叶轮高速旋转而产生的离心力的作用下，球铁混流泵销售价，叶轮流道里的水被甩向四周，压入蜗壳，叶轮入口形成真空，水池的水在外界大气压力下沿吸水管被吸入补充了这个空间。继而吸入的水又被叶轮甩出经蜗壳而进入出水管。由此可见，若离心泵叶轮不断旋转，则可连续吸水、压水，水便可源源不断地从低处扬到高处或远方。综上所述，离心泵是由于在叶轮的高速旋转所产生的离心力的作用下，将水提向高处的，农业混流泵销售，故称离心泵。

（一） 用途：

HW型混流泵为卧式、单级、单吸、悬臂蜗壳式混流泵，适用于农田排灌、工业、城镇给排水及船坞、码头引水等。

I.

Application:

HW Spiral

Mixed-flow pump is a horizontal type， single stage， single suction and

cantilever spiral mixed flow pump， which is used for farmland irrigation and drainage，

industry， town water supply and drainage and water diversion of docks.

（二）泵盖是泵与进水管相连的零件，混流泵，其端面与叶轮之间留有规定的轴向端面间隙（在消除轴承轴向活动间隙以后，保持规定的轴向间隙）。间隙过小产生磨擦，过大则会导致泵内压力水回流，使泵的效率降低，通过增减调整纸垫达到规定的间隙。

II. Pump cover is

the part connected with water inlet pipe.There is an stated axial end face gap

between its end

face and

impeller(Keep the stated axail gap after removing the bearing axial movable

gap).Friction will be

produced if

the gap is too ***all， contrary， if the gap is too large， the pressure water in

pump will reflux which

makes the

feeiciency reduced.Adjust the paper washer and make the gap be stated one.
