QJB submersible mixer

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 excellent hydraulic design structure and high working efficiency. The swept back blade has self-cleaning function to prevent foreign matters from winding and blocking.

3. Mixed use with aeration system can greatly reduce energy consumption, significantly increase oxygen charging and effectively prevent sedimentation.

4. The insulation grade of the motor winding is F, and the protection grade is IP68. The operation of the motor with anti condensation device is more safe and reliable.

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

3、 Application of QJB submersible mixer

The mixing mixer series is suitable for mixing liquid containing suspended solids in sewage treatment plants and stations.

The low-speed plug flow series mixer is applicable to the aeration tank and anaerobic tank of industrial and urban sewage treatment plants. It produces a strong flow of low tangential flow, which can be used for water circulation in the tank and creating flow during nitrification, nitrogen removal and phosphorus removal stages.

4、 Applicable scope of QJB submersible mixer

QJB submersible mixer shall be able to operate normally and continuously under the following conditions:

1. * * * * Medium temperature shall not exceed 40 ℃;

2. The PH value of the medium is between 5 and 9;

3. Liquid density shall not exceed 1150kg/m3;

4. For long-term diving operation, the diving depth is generally not more than 20m.

6、 Precautions for Model Selection of QJB Submersible Mixer

To ensure good results, please provide the following information:

1. Application purpose

2. Pool type

3. Pool size

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

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

6. The mixer must be fully submerged to work, and cannot work in flammable and explosive environment or environment with strong corrosive liquid.

7. Please contact the supplier for model selection.
