Submersible mixer realizes the mixing function by driving the impeller to rotate through the motor. The core of its working principle is energy conversion and fluid dynamics. The specific process is as follows:
1. Power drive and impeller rotation
After the submersible motor is powered on, it drives the impeller to rotate at high speed, converting electrical energy into mechanical energy. The impeller usually adopts a spiral design, which drives the water body to produce axial and tangential composite flow when rotating.
2. Fluid movement and mixing mechanism
Axial spiral flow
The impeller blades drive the slurry to flow in a spiral along the axial direction, forming a strong axial driving force to push the liquid forward.
Centrifugal force
The rotating slurry generates centrifugal force, which further enhances the impeller rotation efficiency and increases fluid turbulence.
Circulation and shear
The impeller drives the surrounding water to form circulation and tangential flow, destroys the floc structure through shear force, and achieves uniform mixing.
3. Formation of gas-solid two-phase flow (special working conditions)
When the impeller of some models rotates to a certain angle, the guide groove forms a negative pressure area to suck in gas or liquid medium. The gas and slurry are fully in contact in the pump chamber to generate a gas-solid two-phase flow mixture, which enhances the stirring effect.
4. Continuous circulation until uniformity
The above process is repeated until the material reaches a uniform mixing state.
5. Synergy of key components:
Reduction mechanism
Adjust the impeller speed to adapt to different viscosity media.
Double mechanical seal:
Prevent liquid from penetrating into the motor to ensure long-term underwater operation.
Deflector design:
Optimize the direction of water flow, reduce energy loss, and improve flow efficiency.
