Qjb Submersible Mixer Pump For Wastewater Treatment

QJB Series Submersible Mixer can be divided into two types : mixing and Agitating series, low-speed flow Propeller series.

Mixing and Agitating series Submersible Mixer Suits for stirring liquids containing suspended solids in sewage treatment plants and industrial processes;

Low-speed flow Propeller series Suits for aeration tanks in industrial and urban sewage treatment plants, which generate strong water flow with low tangential flow, which can be used for circulation and nitrification, denitrification and create water flow for phosphorus removal, etc.

FQJB Series Floating Submersible Mixer Restructured on the basis of QJB series submersible mixer, adding a stainless-steel buoy, the specific selection is implemented in accordance with the QJB series submersible mixer.

Conditions Of Application

In order to ensure the normal operation of the submersible mixer, please make correct selection of the operating environment .

1、The highest temperature of the medium shall not exceed 40℃

2、The scope of pH value of the medium: 5~9;

3、medium density of not more than 1150 kg/m³

4、diving depth in general not more than 20 m when at the long-term diving operation.

Key matters need attention:

The submersible mixer must completely submerse in the water and cannot operate in the inflammable, explosive, highly corrosive and high-temperature environment

The steel expansion bolts must be fixed as required, and the cables must be tightened and fixed after installation.

All use polyurethane impeller, helical gearbox reducer.

Characteristics

1、Compact structure, simple operation and maintenance, convenient installation and maintenance, and long service life

2、The impeller has a reasonable hydraulic design structure, high working efficiency, and the swept-back blade has a self-cleaning function, which can prevent debris from being entangled and blocked;

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

4、The motor winding insulation grade is F, the protection grade is IP68, and NSK/SKF bearings are used.

The motor can be equipped with an anti-condensation device.

The motor uses an over-temperature protection device to make the motor work more reliably;

5、Two mechanical seals; the mechanical seal is sealed with tungsten carbide material, and the rubber material is fluorine rubber
