Function and selection

Denitrification denitrification sludge reflux pumpIt is a sewage and sludge return equipment rarely used outside the aeration tank in the sewage solution industry. The function of the sludge return pump is to maintain the sewage slurry in the sludge tank in an activated sludge state, and to maintain a relatively stable suspended solid concentration outside the aeration tank. Therefore, maintaining an average slurry concentration in the aeration tank requires the use of a sludge return pump. The sludge reflux pump can also be used as a special equipment for the reflux and denitrification of mixed liquids in sewage treatment plants, as well as for irrigation equipment;

The important feature of the product is that it has a high flow rate and low head, which keeps the sewage slurry in a reciprocating state without the appearance of condensation. The temperature of the medium during the operation of the sludge reflux pump cannot exceed 40 ° C, the pH value of the medium in the sludge reflux pump is within the range of 5-9, and the depth of the sludge reflux pump penetrating into the medium cannot exceed 10 meters.

Composed of components such as cables, junction boxes, motors, shafts, seals, bearings, oil chambers, impellers, etc.

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. 1.5KW stainless steel submersible sludge reflux pump 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;

9. Imported cone tube: The purpose of imported cone tube is to form a good 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.
