1. The vertical, outdoor type electric motor is located nearly 1m above the water surface; therefore the possibility of damage caused by splashed water is greatly reduced and the whole setup has a small footprint. 2. Fixed anti-splash board which effectively protects the motor and gearbox from water corrosion. 3. The gearbox uses cone-column gears. All gears have hard surfaces with gear precision Grade 6. The gearbox has the advantages of large bearing capacity, high torque transmission efficiency, small volume, light weight, steady run, low noise and power loss. 4. Bearing support is equipped on the driving end of the rotating brush so a shaft coupling is not needed. By this way the main shaft and brushes can remain in position when replacing worn parts of the gearbox. Installation of gearbox is therefore simple, and the precision of the whole setup can be ensured. 5. Each disk is made of two half disks, symmetrically installed on the main axle. The setup is easy to maintain and very durable. Disks are made of reinforced polypropylene or high-strength lightweight glass steel and pressed to form. They have the advantages of high strength, corrosion resistant, high rigidity and good heat-resistant property. 6. Center-regulating bearing and floating bearing supports are used to align the center automatically and overcome installation errors. They can also compensate for the axial extension caused by changes in temperature. 7. The load of the aerator and the oxygenation rate can be easily changed by adjusting the immersion depth of the rotating disks. |
