About QJB mixer

 

QJB Series Submersible sewage mixer/submerged mixer/sludge mixer adopts excellent hydraulic design, wider type spectrum and optimized structure. Pump casing is produced by special machine tool, which ensures concentricity among shaft bearing, shaft and pump case, and provides better reliability and maintainability. Apply to municipal water supply and drainage, water circulation of air conditioner, agricultural hydraulic engineering, such as irrigation, drain flooded fields ,industrial water supply system, firefighting system, water supply and drainage of heating system, transportation of clean water ect.

Features

 

1. Two mechanical seals are equipped at the submersible motor, the materials of the seal is tungsten carbide. A special finger sleeve structure is adopted at the cable out-coming place for good sealing and anti-corrosion performance.


2.  The impeller is designed with a unique anti-twisting curve in order to have it produce a powerful tangential water flow and avoid wrapping and blocking. A reasonable structure with nice appearance is  designed.


3.  QJB type low speed of thrusters motor winding for class F insulation, protection grade for IP68, choose a lubrication free maintenance, import bearings with oil leak detection room and motor winding overheating protection function, make the motor work more safety and reliable.


4.  QJB type low mechanical seal of the friction thrusters pay material for corrosion resistance of tungsten carbide, all fasteners for stainless steel material.


5.  QJB type low speed thrusters under specified conditions, first failure of average running time before not less than 10000 hours, the machine service life is not less than 15 years.

 

 


Working Principle

 

The propeller blade of a special structure starts slow moving driven by the under-water motor to produce a powerful water flow flowing in a lower tangential direction to make the liquid’s power increased and produce strong stirring to reduce the precipitation under the water, thus realizing liquid stirring and flowing.
