Information

  The 3inch submersible motor factory believes that the submersible motor is generally located at the bottom of the submersible mixer, and the impeller of the mixer is directly installed on the top of the rotor shaft of the motor.

3inch submersible motor

  The 3inch submersible motor factory feels that due to the particularity of the working environment of the submersible mixer, an axial thrust will be generated due to the influence of the water pressure during operation. In order to offset this force, a thrust will be installed between the mixer guide vane and the lower end cover of the motor The bearing capacity of the bearing and the thrust bearing is determined according to the experience of the axial thrust. A thin oil lubrication structure should be designed around the bearing, and thin oil can be injected into the structure regularly to lubricate the sealing end face and the bearing.

  The 3inch submersible motor factory believes that the submersible motor has an input shaft end and an output shaft end, and the output shaft end contains a lower end cover structure, which is connected to the guide vane body of the submersible mixer. They penetrate each other toward the center, so the mechanical seal structure and the thrust bearing are formed as a whole. There is a thrust bearing chamber in the annular inner cavity of the guide vane body, the medium is thin oil lubricant, and the medium of the submersible motor stator is air.

  The 3inch submersible motor factory found that after the submersible mixer is started, the thin oil in the oil chamber will penetrate the entire shaft with the rotation of the shaft, and generate vortices, and the oil level at the radial center will drop significantly in a short time. The mechanical seal may be damaged and lubrication cannot be guaranteed.
