The dosing mixer is mainly composed of a motor, a speed reducer, a stirring shaft and blade etc.. Stirring blade of a variety of forms, but regardless of the form of the blade, mixer in operation, the shaft power consumption has two parts, a part is the blade produce liquid drainage amount, another part is produced by the blade pressure head.
    Blade pressure head can be divided into two parts, namely the static head and the shear stress; Mixer blade in operation, must overcome static head, and shear force makes the material dispersion and mixing.
    Dosing mixer safety precautions:
  1, the installation staff should have the appropriate qualifications and knowledge of mechanical equipment installation personnel to carry out the installation work.
  2, efficient mixer need installed vertically, the vertical deviation should be no greater than 5 degrees.
  3. High efficiency mixing system is strictly prohibited to mix solids and liquids with high viscosity.
  4, motor and bearing temperature can not run in more than 75.
  5, motor and bearing and gearbox cannot run in lubricating oil shortage situation.
  6, stirrer shaft and blades cannot run in bending or deformation condition. Such as the discovery of shaft bending phenomenon or blade deformation phenomenon, should immediately stop processing or replacement.
  7, efficient mixing system in the process of operation will be prohibited from entering the reaction tank so as to avoid damage to the shaft and blade mixer.
  8, if people need to enter the reaction tank to clean or repair work, you must the motor power is cut off and hung "prohibit closing" warning signs. In the manual tank cleaning and maintenance operations, the reaction pool must have special care.
  9, efficient mixing system after a period of operation, such as reaction pool with impurities, sediment and debris, should promptly stop operation rinse or manual cleaning to ensure the safe operation of the mixer.
  10, efficient mixer shall be correctly installed and used in order to ensure the stable operation of long period safety.
