Sludge reflux pump guide tube

Commonly known as equipment:

Submersible sludge reflux pump, sewage reflux pump, sludge reflux ratio, sludge treatment, reflux pump, sludge conveying pump, sludge reflux, submersible reflux pump, sludge reflux pump, mixed liquid reflux pump, sludge pressure filtration pump

Sludge reflux pump guide tubeScope of application
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.

Sludge reflux pump guide tubeTerms of Use

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

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

3. Submersible depth of 10m.

Structural abbreviation

The designed device components and equipment spare parts enable the sludge reflux pump to achieve optimal 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 surface and a swept back shape. It operates unobstructed and has self-cleaning function;

9. Imported cone tube: The purpose of imported cone tube is to form a better flow state;

10. Discharge joint: The discharge joint is used to fix the inlet cone pipe on the outlet pipe;

11. Guiding device: The guiding device consists of two pipes (conduits) and an upper conduit clamp.

Product Features

1. Designed with micro head and high flow rate, high efficiency;

2. Anti clogging, winding, and reliable use;

3. Using 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.
