Mixer including work parts (vertical stirring shaft, stirrer), supporting part (bearing assembly, frame), and drive (motor, reducer) and connection accessories, etc. Agitator drive device is installed at the top of the reaction pool, use flange connection between motor and reducer, in order to install and maintain.
Motor for outdoor type, insulation class F, protection level is IP55.

    (1) speed reducer
    A. each mixer is equipped with a reducer, reducer used principle of K-H-V planetary transmission and curtate Cycloid Teeth joggling with novel mechanical transmission, the reducer has a strong bearing capacity, high reduction ratio, high transmission efficiency, the smallest volume, low noise and a long service life. In the specified operating range, the speed reducer can run continuously.
    B. reducer all the transmission parts are strictly processed, precision machining, grinding, contact and lubrication is good, smooth running, low noise, the output shaft and the input shaft are no additional axial force, long service life.
    C. motor, the replacement of all bearings and the replacement of the fuel system is convenient, the machine on the lifting of the lifting lug.
    D. all support bearings are anti wear spherical or cylindrical bearing. The service life of all wear bearing in the speed reducer is 50000 hours or more.
    E. dew in the outer bearing grease lubrication of the reducer, the installation of the adjustment with grease, seal. The other bearing and the cycloid cup used continuous spray splash lubrication, or continuous lubrication oil pump.
    F. reducer has the oil leakage prevention device, and control the normal oil level dipstick.
    G. to undertake the drive shaft and impeller weight and prevent running due to loading leads to the axis is tilted, and prevent when the mixer running gear misalignment, the output shaft of the speed reducer is of sufficient size and stiffness.
    (2) the shaft
    A. drive shaft with carbon steel tube. Made after annealing treatment, paddle mixer shaft for cantilever shaft, do not use fixed at the bottom of the bearing. Shaft surface impurities without defect, in order to eliminate its influence on shaft fatigue strength and corrosion resistance. Axis linear, verticality and precision accurate, axial length per meter, maximum allowable deviation of 1 mm.
    B. shaft tank should be considered in the design of impeller impeller move up and down, the minimum distance is 150 mm, the movement of the impeller does not affect other devices.
    C. mixer shaft with stainless steel coupling type D clip shell connected to the output shaft, connecting to adequately.
    D. the design of the transmission shaft without stabilizer, its running speed limit in the first harmonic vibration frequency of less than 65%. On critical speed, torque, and the calculation of bending force is fully aware of the blade and the quality of the shaft and inertia.
    (3)the blade, blade is made of carbon steel.
    (4) drive motor
    A. motor for horizontal AC squirrel cage induction motor, its design, manufacturing and experimental factory should comply with the corresponding standard, anti leakage type, 380V, three-phase, 50Hz, power output which does not exceed the power shown on the motor nameplate.
    B. motor at an altitude of 3000m to ensure that it can meet the rated power.
The power of C. motor can meet the special needs of the mixer.
    3 material and anti-corrosion: the mixer of underwater parts (shaft and blade) using carbon steel and do anti-corrosion treatment.
    4 scope of supply: the main shaft, mixing blades, drive devices and connection accessories, etc..
