In the high speed revolving processing, the material indraft from upper and lower of the impeller, then ejects from the slit of the impeller and the stator.

叶轮高速旋转过程中，将物料从叶轮的上下方吸入，然后从叶轮和定子的缝隙中抛出。

Through the study to the vortex theory, especially the mathematical model of Burgers vortex, we have got some factors, which affect the oil indraft performance of the device qualitatively. The main factors are principal axis rotation speed, structure dimension of whisk impeller and drainage impeller, installed positions of whisk impeller and characters of spilled oil.(3) According to the analysis of impact factors, from simple to complexity, we have done the experiment study to the artificial-jellyfish device by three steps.

研究表明：轴面流道形状和叶轮包角影响叶轮内部压力场和速度场的均匀性，导致两个叶轮的水力效率值存在约2%的差别。

In curve fitting, the speed-flow rate curve shows that the curve of 16mm pitch wheel is a line and that of 12mm pitch wheel is a down-winding curve, the speed-pressure curves of two pitches both are up-winding curves and in the resistance-flow rate curves the curve of 12mm one has lower slope than that of the 16mm one.

曲线拟合结果显示，在转速-流量曲线中，16mm螺距叶轮为一直线，12mm螺距的叶轮为一向下弯曲的曲线；转速-压力曲线显示两者都是向上弯曲的曲线；阻力-流量曲线显示12mm螺距的叶轮斜率较小。

Using a model regarding the impeller as homogeneous rotating circular with same thickness and various density,the residual strain field and plastic deformation zone size of certain supercharger impeller were calculated at 30 000 r／min over-speeding preload by means of axial symmetry plane stress elasto-plastic analysis method,and were compared with the result of resistance strain measurement method.

Grundfos NSBasic, is a single-stage impeller and the two-stage impeller of the small end of the stomach pump , it has a cast iron pump , composite material or cast iron impeller can provide long-term stable and reliable in operation.

格兰富NSBasic，是单级叶轮与双级叶轮的小型端胃泵，它具有的铸铁泵，复合材料或铸铁的叶轮可以于提供长期稳定的可靠运行。

The pressure fluctuations were measured at different positions along the axial direction on the tonge. The coherence analysis was utilized for illustrating the blade passing frequency cancellation mechanism. A 3-D flow visualization method, which overcame the blind slight from LDV and PTV, was used to present the differences of internal flow patterns.

实验中分别进行0度、5度与10度三种叶轮扭转角之设计，在横流扇出风口以声学人偶进行噪音量测，评估不同叶轮扭转角在操作转速下之风扇噪音、并分析其声音品质；另外在舌端上不同的轴向位置撷取其压力扰动频谱进行相干性分析，探讨舌端上因不同叶轮扭转角对周期性压力扰动之破坏之探讨。

The pump body consists of suction chamber, liquid storage chamber, turbination chamber, liquid return port, gas-liquid separation chamber, etc. After the pump starts normally, the impeller will suck the liquid in the suction chamber and the air in the inlet line so that the both can mix fully in the impeller. Due to the centrifugal force, the liquid along with the gas flows towards the outer edge of the turbination chamber and then a belt of white foam with a certain thickness and a liquid ring with high-speed rotation come into being on the outer edge of the impeller.

泵体由吸入室、储液室、涡卷室、回液孔、气液分离室等到组成，泵正常起动后，叶轮将吸入室所存的液体及吸入管路中的空气一起吸入，并在叶轮内得以完全混合，在离心力的作用下，液体夹带着气体向涡卷室外缘流动，在叶轮的外缘上形成有一定厚度的白色泡沫及高速旋转液环。

In modern types such as the velometer and similar German instruments the plate is replaced by a small vane under spring instead of gravity control, which carries a pointer moving over a scale of air speed

在现代类型的仪器中，例如在速度计和类似的德国仪表中，这种摆动片已用一个小叶轮代替，叶轮利用弹簧控制而不用重力控制。叶轮上装有一个指针，可在标示有气流速度的刻度盘范围内移动

When pump starts, the lower impeller lifts the solution up step by step. And the extreme centrifugal force from the enlarged higher impeller stops the solution as it entering the higher impellr. At the same time, the full solution in the chamber stops the air mixed with the solution in the chamber to go down. This way masterly eliminates both big problems of vertical sealless pump, overflow at high pressure and bubbles at big flow.

塑宝SV泵剖面结构SV Super Series Analytical cross section SV泵剖面结构泵开始运转时，底部叶轮将液体逐步上推，待液体进入上部叶轮时，即受加大之背叶的强大阻力而无法上升，但上部叶轮所卷入液体中的空气，却受阻於水室中贮满的液体而无法下降，如此巧妙地排除了立式无轴封泵高压时溢流，或大流量时吸入空气的两大难题。
