摘要：

   旋涡泵（Vortex pump）是靠旋转叶轮对液体的作用力，在液体运动方向上给液体以冲量来传递动能以实现输送液体的泵。叶轮为一等厚圆盘，在它外缘的两侧有很多径向小叶片。在与叶片相应部位的泵壳上有一等截面的环形流道，整个流道被一个隔舌分成为吸、排两方，分别与泵的吸、排管路相联。泵内液体随叶轮一起回转时产生一定的离心力，向外甩入泵壳中的环形流道，并在流道形状的限制下被迫回流，重新自叶片根部进入后面的另一叶道。因此，液体在叶片与环形流道之间的运动迹线，对静止的泵壳来说是一种前进的螺旋线；而对于转动的叶轮来说则是一种后退的螺旋线。旋涡泵即因液体的这种旋涡运动而得名。液体能连续多次进入叶片之间获取能量，直到最后从排出口排出。旋涡泵的工作有些像多级离心泵，但旋涡泵没有像离心泵蜗壳或导叶那样的能量转换装置。旋涡泵主要是通过多次连续作功的方式把能量传递给液体，所以能产生较高的压力。在能量传递过程中，由于液体的多次撞击，能量损失较大，泵的效率较低，一般为20～50％。旋涡泵只适用于要求小流量（1～40米3／时）、较高扬程（可达250米）的场合，如消防泵、飞机加油车上的汽油泵、小锅炉给水泵等。旋涡泵可以输送高挥发性和含有气体的液体，但不应用来输送粘度大于7帕·秒的较稠液体和含有固体颗粒的不洁净液体。旋涡泵的特点流量小，扬程高，具有自吸功能，可用来输送粘度小于5度E的无固体颗粒及其类似于水的液体。如汽油、煤油、酒精等，可用作小型蒸汽锅炉补水、化工、制药、高楼供水等用途。过流部件还有不锈钢等材质可用来输送酸、碱类有腐蚀性的液体。输送介质温度为-20~+80度。从结构可分单级、双级、多级；直联形式等。

65WB-50-type vortex pump design
 Abstract:    Vortex pump  by rotating impeller forces the liquid in the liquid to the liquid movement in the direction of the impulse to pass in order to achieve transfer of kinetic energy of the pump liquid. Impeller for the first thick disk, in which there are many on both sides of the outer edge of the small radial blades. With the corresponding parts of the pump blades have a first-class section of the shell of the annular flow channel, the entire flow channel separated by a sub-lingual absorption become exclusive two sides, respectively, and the suction pump, associated piping row. Impeller pump with the rotating liquid with a centrifugal force generated when the outside shell thrown into the ring pump flow and the shape of the flow constraints are forced to return to the roots from the leaves into the back of another leaf Road. Therefore, the liquid in the leaves and annular flow of movement between the trace of the static pump shell is a spiral forward; and for the rotation of the impeller is a backward spiral. Vortex pump that is a result of fluid movement, named after such a vortex. Liquid can be for multiple entry and access to energy between leaves, until the final discharge from the outlet. Vortex pumps work like a multi-stage centrifugal pump some, but not as centrifugal vortex pump volute or guide vane as the energy conversion device. Mainly through the vortex pump Zuogong many ways for the energy transfer to the liquid, they are able to generate higher pressure. In the energy transfer process, as a result of the repeated impact of liquid, the larger energy loss, the lower the efficiency of pump is generally 20 to 50%. Vortex pump requirements apply only to a small volume (1 ~ 40 m 3 / h), high head (up to 250 meters) of occasions, such as fire pumps, aircraft refueling vehicle the fuel pump, boiler feed pump and other small. Vortex pumps can be highly volatile and transmission fluids contain gas, but the viscosity should not be used to transport more than 7 seconds Pago • more viscous liquid and solid particles containing the liquid is not clean. The characteristics of vortex flow pump small, head high, with a self-priming function, can be used to transport less than 5 ° E viscosity of the non-solid particles and liquid similar to water. Such as gasoline, kerosene, alcohol and so on, almost on a daily basis can be used as a small steam boiler, chemical, pharmaceutical, high-rise water supply purposes. There are stainless steel flow components can be used to transport materials such as acids, alkali corrosive fluids. Transmission medium temperature of -20 ~ +80 degrees. From the structure can be divided into single-stage, dual-level, multi-level; Direct form.
