Structural decomposition of submersible reflux pump - sludge pump

Submersible reflux pump is a type of vertical centrifugal pump, mainly used for conveying mixed liquids in municipal engineering and industrial production processes, and for discharging sludge and sewage. Submersible reflux pump is a specialized equipment for mixed liquid reflux, denitrification and nitrogen removal, and is used in ground drainage projects where micro head and high flow are required for re circulation. The meaning of mixed liquid reflux is that the effluent from the aeration tank flows back to the inlet and enters the aeration tank again for reaction together with the influent.Structural decomposition of submersible reflux pumpBearing, impeller, seal, temperature monitoring, material, specific analysis

Structure of submersible reflux pumpsolution：

bearing

Imported bearings for submersible reflux pumpsBrand, with a lifespan exceeding100000Hour.

impeller

The impeller of the submersible reflux pump uses advanced axial running three bladed wheels made of stainless steel material, which is corrosion-resistant and wear-resistant. The design of the impeller can simultaneously meet the requirements of high flow rate and low head, and form a large flow rate in the axial direction. The impeller has the best hydraulic design structure, and the swept back blades have self-cleaning function, anti clogging, and anti winding.

seal

The sealing of the submersible reflux pump adopts dual motor sealing technology, and the shaft seal is a mechanical seal to isolate the oil chamber from the surrounding medium, ensuring safe and reliable sealing and improving the reliability of movement.

Temperature monitoring

The insulation level of the motor winding isFGrade. The protection level isIP68Adopting advanced overheating protection, once the motor is overloaded, the medium temperature is too high, or other reasons cause overheating, the temperature sensor will automatically shut down the water pump when the temperature limit is exceeded. Ensure the safe and reliable operation of the product
