They can be applied to the city water supply, the waterworks, the breweries, the chemical industry, the construction, the mining, the metallurgy, the paper making, the sugar producing and the canned food industry, particularly applicable to the sewage treatment works; meanwhile, some of the impellers are suitable for conveying the object which contains solids or long-fiber non-abrasion solid-liquid mixtures.

适用于城市供水、水厂、啤酒厂、化工、建筑、矿山、冶金、造纸、制糖、罐头食品工业，特别适用于污水处理工程；同时部分叶轮适合输送含固体物或长纤维的非磨蚀固液混合物。

The head and efficiency of the ten models were predicted and compared with the experiment results. The theoretical head and hydraulic loss in impellers and volutes were calculated by the two methods.

预测了各模型的总效率和扬程并与试验值做了比较；计算了理论扬程以及叶轮和蜗壳内的水力损失。

But as for impellers and diffusers, not much research was carried on volutes and their design is still based on traditional one-dimensional method.

但是相对于叶轮扩压器而言，关于蜗壳的研究比较少，并且蜗壳的设计也停留在传统的一维设计方法上，此设计方法不符合实际流动情况，导致蜗壳内流体参数不均匀性的增强，进而影响叶轮和扩压器内的流动，降低压缩机整体性能。

The sones fall into the high-speed turning impellers from the top of the machine.Under the function of high-speed centrifugal force,the stones crushed the others distributed around the impeller in the form of umbrella.After the stones impact each other,the eddying motion is formed between the impeller and main case to bring obout many times mutual impactind,rubbing,and crushing till the granularity required is achieved.

石料由机器上部直落入高速旋转的转盘，在高速离心力的作用下，与另一部分以伞形方式分流在转盘四周的石料产生高速度的撞击与高密度的粉碎，石料在相互打击后，又会在转盘和机壳之间形成涡流运动而造成多次的互相打击、摩擦、粉碎、直至粉碎成所要求的粒度。

Comparing tow methods of efficency pre-estimation, it finds out the new method fit for super-low specific-speed pump. Acoording to the study and comparison on efficency and reliability, the thesis points out merits and faults of the 5 types of impeller, and draws a conclusion that the complex impeller and partly blocked-flow-passage impeller are fit for the impellers of super-low specific-speed centrifugal pump.

比较了泵效率预估的方法，提出了适合于极低比转数泵效率预估的新方法，并对其性能要求的效率和可靠性两方面进行了研究比较，指出了五种形式叶轮各自的优缺点，得到结论：复合叶轮和部分堵塞流道的一般叶轮适合作极低比转数泵叶轮。

In order to study the flow characteristics inside the double-channel impeller, a testing pump was designed and produced according to the special requirements for PIV measurement with two different impellers, i.e., the double-channel impeller and the two-blade impeller.

为研究双流道叶轮与普通叶片式叶轮的内部流动区别，设计制作了满足粒子图像测速仪测量要求的模型泵，模型泵的叶轮有双流道和双叶片2种形式。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.
