Introduction
QJB type Submersible Mixer, a key equipment used in the water treatment technology, can meet the technological requirement for homogeneity and fluidity of solid-liquid two-phase flow and solid-liquid-gas three phase flow in biochemical course of the water treatment process. It is composed of the submersible motor, impeller, and installation system etc.. The submersible mixer is in direct connection structure. Comparing with the traditional high-power electric motor that retards speed by a speed reducer, it is highlighted by compact structure, low energy consumption, facile maintenance. The impeller shaped by finishing casting or punching, which has high precision, forceful thrust as well as simple, nice-looking and streamlined profiling. The series of products are applicable to the places that requires for solid- liquid agitating or mixing.  

Structure
The schematic drawing of the structure is shown as follows: 


Application
QJB submersible mixer and agitators are able to be located at any positionm, who can achieve the function of creating water flow, improving water quality, increasing oxygen content in the water and effectively preventing the sedimentation of the suspended substances. They are widely used in waste water treatment plants and industry process to agitate the suspended substances contained water, watery slurry, icy water, liquid from industry process, roast liquid, etc. They can be also used to create water flow in the tank, to open up water channel, to oxygenate fishing pound, to prevent pound form icing. 

Performance Parameters
The perfomance paramfers of the submersible mixer are shown in the following table with the rated voltage of 380v and the frequency of 50Hz: 

Notes:
1 In mixing & agitating series of the above table, the value listed in the column of Weight contains the weight of the dome;
2 Winding insulation class of the motor: Class F; Protective grade; IP68;Operating mode of the motor:Operation for 24 hours. 
3 We can suply the motor with class H winding insulation.
