Impeller is the core part of slurry pump, in this thesis, the filling and solidfication process of a real hyperchrome white iron impeller were simulated by foundry CAE. It was found that there are some defects by traditional design approach.

叶轮是水泵的核心零件，本论文选取一渣浆泵叶轮，材质为高铬铸铁，该叶轮由于存在铸造缺陷，废品率较高，使用寿命短，使用过程中曾发生严重事故，造成了非常大的负面影响，严重影响了正常的生产秩序。

Under function of impeller with high rotating speed, the used sand will be cast to the wearable junk ring to remove the inert film on su rface of the sand via mutual collision and friction between sand and junk ring, impeller and case of machine, sand and sand.

工作时旧砂在高速回转的叶轮作用下，抛向耐磨衬圈，通过砂粒与衬圈、叶轮与机盒、砂粒与砂粒之间的相互碰撞和摩擦，去除砂粒表面的树脂惰性膜。

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。

In the role of centrifugal force, the liquid was thrown from the outer edge of impeller centre and access to energy, high-speed impeller to leave the outer edge of worm-shaped pump into the shell.

在离心力的作用下，液体从叶轮中心被抛向外缘并获得能量，以高速离开叶轮外缘进入蜗形泵壳。

The interior flow of stirring impeller is calculated by slightly modified optional quasi-normal intersection surface method for calculating three-dimensional interior flow of impeller mechanism.

对计算叶轮机械内部三元流动的任定准正交面法略加修改后，用于计算搅拌桨内部的流动。

The three-dimensional optional quasi-normal intersection surface method for calculation of interior flow of impeller mechanism is slightly modified,then used to calculate the interior flow of stirring impeller.

对计算叶轮机械内部三元流动的任定准正交面法略加修改后，用于计算搅拌桨内部的流动。

Impeller rotates clockwise, the right part of the space between two blades is gradually increasing, in confined conditions, with the air volume increases, pressure decreases, the formation of vacuum pumps and air through the pipeline suction tube into the vacuum pump the right side of the crescent-shaped shell inspiratory mouth to be sucked into vacuum pump, vacuum pump impeller left some space between the two blades is gradually reduced, so the air is compressed, the pressure then increased, and finally through the vacuum pump shell crescent-shaped exhaust port from the left side of vacuum pumps, gas separator into the water box, so that was taken out after the separation of the recycled water reuse.

叶轮顺时针方向旋转时，其右半部分两叶片之间的空间逐渐增大，在密闭条件下，随着空气体积的增大，压力随之降低，形成真空，水泵和管路内的空气通过吸气管，进入真空泵泵壳右侧的月牙形吸气口被吸入真空泵，真空泵叶轮左半部分两叶片之间的空间是逐渐减小的，因此空气被压缩，压力随之增高，最后通过真空泵泵壳左侧月牙形排气口排出真空泵，进入水气分离箱，使被带出的循环水分离后再重复使用。

It was found that at design condition, the double-channel impeller had better flow pattern, smaller separation and vortex area than that of the two-blade impeller. It was also proved that the measured results showed great agreement with the calculated ones.

结果表明：与双叶片叶轮相比，双流道叶轮流道内脱流-旋涡区的范围较小，流态更好；PIV测试结果与自编程序和FLUENT软件数值模拟结果基本一致。

It demonstrated that without aeration the best type of agitator is three-blade impeller and the height is 1/3 diameter of impeller. Aeration can improve the suspension of sludge.

结果表明在无曝气的情况下，选用三叶推进式搅拌器，搅拌器离底高度为1/3搅拌器直径时所需要的临界搅拌速率最低。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.
