What is the important role of submersible mixer impeller optimization?

As we all know, the main role of submersible mixers in sewage treatment is stirring and pushing. The main factors affecting the mechanical properties of submersible mixers are the shape, size, and angle of the impeller. Submersible mixer equipment is usually after a three-blade impeller, and the impeller can be cut according to the material, cycle for different reactions, and provide a more suitable response than the shear cycle.

For this type of impeller, we can slightly optimize to produce maximum axial flow. In the optimized design of submersible mixer impellers, double curved guide covers can be used. The main reason is that the flow of the mixer impeller is mainly axial movement. To reduce the losses caused by flow and tip vortex, guide covers can be used and developed. The guide cover has a proper water design, and the flow deviation can be improved by controlling the inflow pattern. The pressure difference on the guide cover increases the axial flow and reduces the radial flow.

It can be seen that the hydraulic load and vibration reduction effect of the impeller blades can make the equipment longer and more stable. This guide can also solve the problems caused by the impeller. When the submersible mixer is at a shallow liquid level, it is easy to cause air vortexes to enter the propeller mixer impeller from the liquid surface, which leads to a decrease in the vibration performance of the impeller. The use of a dome can prevent vortices.

Therefore, impeller optimization is one of the most critical components of a submersible mixer, which can improve the efficiency of the submersible mixer, enable the submersible mixer to maximize the flow field and create the best flow state. In addition, the choice of impeller shape can consider the situation of improving the resistance ratio, and can also consider whether it can improve the cavitation performance of the impeller.
