Anaerobic zone submersible thruster QJB1.5/4-1100/2-51B

Anaerobic zone submersible thruster QJB1.5/4-1100/2-51B Selection instructions:

The Pinyin abbreviation for QJB submersible thruster is 1.5 for motor power and 1100-2500mm for impeller diameter

Product Usage

The low-speed submersible thruster for aerobic tanks is suitable for aeration tanks and anaerobic tanks in industrial and urban sewage treatment plants. It generates strong water flow with low tangential flow and can be used for water circulation, nitrification, denitrification, and phosphorus removal stages to create water flow.

Scope of application:

The low-speed submersible thruster of the aerobic tank should be able to operate continuously under the following conditions:

1. The maximum medium temperature shall not exceed 40 ° C;

The pH value of the two media is between 5 and 9;

3. Liquid density not exceeding 1150kg/m3;

4. Long term diving operation, with a diving depth generally not exceeding 20m.

Key precautions:

The low-speed submersible thruster in the aerobic tank must work underwater; Cannot work in environments with flammable, explosive, or highly corrosive liquids; The steel expansion bolt must be fixed as required, and after installation, the cable must be tightened and fixed securely

When selecting low-speed submersible propellers for aerobic tanks, if the blade diameter exceeds 2M, it is recommended to use a gearbox reducer.

Anaerobic zone submersible thruster QJB1.5/4-1100/2-51BPerformance characteristics:

1. The low-speed submersible thruster of the aerobic tank has a compact structure, simple operation and maintenance, easy installation and maintenance, and a long service life;

The impeller of the low-speed submersible thruster in the aerobic tank has excellent hydraulic design structure, high working efficiency, and the swept back blades have self-cleaning function, which can prevent debris entanglement and blockage;

Mixing with the aeration system can significantly reduce energy consumption, increase oxygen filling capacity, and effectively prevent sedimentation;

The insulation level of the motor winding is F, and the protection level is IP68. High quality bearings and motor anti condensation devices are selected to make the operation of the motor safer;

5 mechanical seals;

Application of QJB low-speed submersible thruster:

Aerobic tank low-speed submersible thruster is used in aeration tanks and anaerobic tanks of industrial and urban sewage treatment plants. It generates strong water flow with low tangential flow, which can be used for water circulation in the tank and creating water flow during nitrification, denitrification, and phosphorus removal stages.
