直接的方法是基于设计逐案分析的方法是机翼形状指定第一。

Centrifugal energy saving analysis and measures: 1 improve the efficiency of centrifugal pumps a first step, in the selection of comparison, when many suppliers Selection program, in considering the cost-effective choice as far as possible under the premise of efficient programs; the second step , accredited professionals must Mill producers, affecting the pump efficiency of the key components such as impellers, pump body, pump cover, diversion devices, such as the manufacture of quality producers, especially for the airfoil impeller , outlet angle, leaves the sub-degrees, the shape of flow channel, to control the quality of finish, etc., so that products are delivered in the current production under the conditions of highly efficient products; the third step, the scene in the production of installation and debugging process, pump to ensure a solid foundation, with the driving machine for good, before and after valve flexible piping layout design is reasonable, on-site control is feasible and safe, the complete and accurate monitoring instrumentation to ensure that pump operation can carry out real-time monitoring; fourth step , are at long-term operation of water pumps necessary to pay attention to the equipment inspection and found anomalies reflect real-time reporting, in the normal minor repairs, overhaul cycle, to deal with the replacement of wearing parts inspection to ensure the pump's long-term safe and efficient operation.

第一步，在选型时多比较各供应商的选型方案，在考虑性价比的前提下尽量选用效率高的方案；第二步，派驻一定的专业人员驻厂监制，对影响水泵效率的关键零部件如叶轮、泵体、泵盖、导流器等的制造质量进行监制，尤其对叶轮的翼形、出水角、叶片的分度、流道的形状、光洁度等质量进行控制，使交付的产品是在当前的生产条件下的高效率的产品；第三步，在生产现场的安装调试过程中，要保证泵的基础牢靠，与驱动机对中良好，前后阀门开关灵活，管道布置设计合理，现场控制安全可行，各运行监控仪表齐全准确，保证泵的运行过程能够进行实时监控；第四步，是在水泵的长期运行中要注意对设备的点检，发现异常情况即时反映汇报，在正常的小修、大修周期中，应对各易损件进行检查更换，保证泵的长期高效安全的运行。

According to the design performance aim, we estimate the overall parameters and complete the shape design of two schemes. Normal and tailless layouts are respectively applied. Then we use different airfoil and wing with low Reynolds number and the aerodynamic analysis of the result is achieved.

根据设计性能指标，进行总体参数估算，完成了两种方案的外形设计，分别采用了正常和无平尾的布局形式，进行了不同的低雷诺数翼型和机翼配置，并对设计结果进行了气动分析。

Meanwhile, it can control main blade/splitter blading and the shape of trailing edge of the airfoil.
