Introduction to the performance and features of submersible propellers: These propellers belong to the low-speed flow-promoting mixer category and are suitable for use in aeration tanks in industrial and municipal wastewater treatment plants. They generate strong water currents with a low shear force, which can be used for circulation as well as to create flow patterns during the nitrification, denitrification, and phosphorus removal processes. The performance characteristics of submersible propellers are summarized as follows: 1. The impeller of the submersible propeller features an optimal hydraulic design, enabling high efficiency; its swept-back blades have a self-cleaning function that prevents debris from getting entangled and causing blockages. 2. The diving propeller features a compact structure, simple operation and maintenance, easy installation and repair, and a long service life. 3. When used in combination with an aeration system, it can significantly reduce energy consumption, increase oxygen supply, and effectively prevent sedimentation. 4. The two mechanical seals of the submersible propeller are made of tungsten carbide-tungsten carbide. All exposed fasteners are made of stainless steel. 5. The motor winding insulation grade is F, and the protection grade is IP68. Imported bearings as well as a proprietary patented anti-dew device for the motor are used to ensure safer and more reliable operation of the motor.
