Product Introduction of Sludge Reflux Pump for Primary Denitrification Tank QJB-W5/12 Through Wall Reflux Pump

The QJB-W type sludge reflux pump is a new product developed based on the production technology of submersible mixers. This pump is an equipment for mixed liquid reflux and denitrification denitrification in secondary sewage treatment plants, and can also be used for pumping purified water during surface drainage; Irrigation and control of waterway systems; Micro head and high flow areas are required in the recycling or mud suction circuits during wastewater treatment.

Conditions for use of sludge reflux pump

1. During continuous operation, the medium temperature shall not exceed 40 ℃;

2. The pH value of the medium is 6-9.

3. The maximum submergence depth is 10m.

Introduction to the structure of sludge reflux pump Submersible wall penetration reflux pump QHB5/12 with fast flow rate

Specially designed device components and equipment spare parts enable the sludge reflux pump to achieve excellent performance.

1. Cable: The cable adopts a specially designed waterproof cable;

2. Junction box: The junction box is fully enclosed and isolated from the surrounding liquid and stator box;

3. Motor: 50Hz squirrel cage 3-phase submersible asynchronous motor, F-class insulation, protection level IP68. The motor is cooled by the surrounding medium;

4. Shaft: The shaft of the electric motor is made of stainless steel material, and the rotor undergoes dynamic balance testing;

5. Sealing: The static seal is an O-ring seal. The shaft seal is a mechanical seal that isolates the oil chamber from the surrounding medium;

6. Bearing: Imported bearings are used, with a designed service life of over 100000 hours;

7. Oil chamber: Oil is used to lubricate and cool the mechanical seal friction pair, and isolate the permeate;

8. Impeller: The impeller has three blades, which are wide and thin, with a smooth and swept back surface, efficient and unobstructed operation, and have self-cleaning function;

Features:

1. Specially designed for micro head and high flow rate, with high efficiency;

2. Anti clogging, winding, and reliable use;

3. Using brand new sealing materials, it can safely and continuously operate for more than 10000 hours;

4. Compact structure, easy installation and maintenance;

5. The host adopts a stamping structure, with small size, high precision, corrosion resistance and no noise;

6. Equipped with leakage and motor overload protection (alarm) devices to ensure product safety and reliability.
