The motor of the mixer is installed beyond the liquid level, that is especial suit for the environment with high temperature, high concentration and corrosive liquid. Applications适用范围 与传统的桨叶搅拌相比，具有混合均匀、效率高、能耗 低、无死
3、角的特点。 结构简单，便于安装维护。 对于各种水处理工艺中水体搅拌、化学药剂的混合搅拌 效果更为突出。 大比表面积叶轮，配备功率小，节能。 In comparison with traditional blade paddle mixer, MH has the feature of mixing equality, high efficiency, low energy consumption and no dead zones. Simple structure and easy for installation and maintenance. Used especially for t

6、双曲面搅拌机由传动部件、叶轮、底座及吊装系统组成。The MH hyperboloid mixer is composed of transmission part, impeller, base and hoisting system . Construction 工作特性 Operating features MH双曲面搅拌机可以创建大容积流量的搅拌，并能 以较小的动力获得大面积循环、柔和的水流。独特的 叶轮结构设计，最大限度地将流体特性与机械运动完 美结合。双曲面叶轮的曲面是方程为 xy=b 曲线沿y轴 旋转而构成的曲面体；为了迎合水体流动，设计从叶 轮的中心进水，这一方面减少了进水紊流

The curved surface of hyperboloid impeller is shaped by the curve of formula xy=b rotating around y axis, in order to cater to the water fl
9、owing, the impeller is designed to feed water from the center, on one hand, the turbulent flow is reduced, on the other hand, the pressure of the liquid on the impeller surface is equal and even, therefore the machine will be balanceable in the mo- vement status.

14、 parameters and installation mode. The type selection of hyperboloid mixer is basically confirmed according to the effective service area of each hyperboloid mixer, and according to the principle that the ratio of length to width not over 2 to 1, the rectangle pond will be equally divided into working cells, so as to confirm the mixers quantity.
