Mixer diameter 620mm impeller

1. Performance characteristics of QJB submersible mixer

    1. QJB submersible mixer has compact structure, simple operation and maintenance, convenient installation and maintenance, and long service life.

    2. The impeller has the best hydraulic design structure and high working efficiency. The swept-back blade has a self-cleaning function to prevent entanglement and blockage of debris.

    3. Mixed use with aeration system can greatly reduce energy consumption, increase oxygenation capacity significantly, and effectively prevent precipitation.

    4. The insulation class of the motor winding is F, and the protection class is IP68. Imported bearings and a unique patented motor anti-condensation device are selected to make the motor work safer and more reliable.

    5. Two mechanical seals, made of tungsten carbide-tungsten carbide. All exposed fasteners are stainless steel

2. Model meaning of QJB submersible mixer

Low-speed push-flow mixers are suitable for aeration tanks and anaerobic tanks of industrial and urban sewage treatment plants. They produce strong water flow with low tangential flow, which can be used for water circulation in the pool and water flow in the stages of nitrification, denitrification and phosphorus removal.

3. Product use of QJB submersible mixer

The mixing and mixing series mixers are suitable for mixing liquids containing suspended solids in sewage treatment plants and stations.

Six, QJB type submersible mixer selection precautions

In order to ensure the best results, the user is requested to provide the following information:

1. Purpose of use

2. Pool type

3. Pool size

4. Media characteristics include viscosity, density, solid content, etc.

5. The matching power required by the mixer is determined according to the volume, the density, viscosity and the depth of the mixing liquid. One or more mixers should be used according to the specific situation.

6. The mixer must be completely submerged in water to work, and cannot work in an flammable and explosive environment or an environment with strong corrosive liquids.

7. For selection issues, please contact the supplier.
