Low speed submersible thruster is a submerged water treatment equipment that combines mixing and propulsion functions. This device uses a large impeller to propel the liquid forward while thoroughly stirring and mixing the mixed liquid in the oxidation ditch (or other water treatment facilities), in order to improve the water flow conditions of the oxidation ditch sewage treatment facility, achieve the required flow rate for the process, prevent sedimentation of sludge, and improve sewage treatment efficiency.

a 、 The dedicated motor of this machine adopts triple protection of overload, phase failure, and leakage prevention to ensure the performance of the equipment during underwater operation;

b、 The gearbox adopts a cylindrical helical gear transmission with a hard tooth surface made of excellent alloy gold material, which has the characteristics of high load-bearing capacity and small volume;

c、 The connection points of the host are sealed with cross-sectional and radial seals, and the output shaft is sealed with silicon carbide or tungsten carbide mechanical seals to ensure the reliability of the seal;

d、 The impeller of the propeller adopts the theory of ship propeller propulsion and is optimized by computer design;

e、 The two blade high thrust, self-cleaning impeller is made of high-strength and corrosion-resistant fiberglass processed as a whole, which is lightweight and has good strength. Under certain input power conditions, it can obtain a large water flow thrust.
