Industrial Agitators are devices for forced convection and uniform mixing of liquid and gaseous media. The type, size, and rotational speed of the Industrial Agitators all affect the distribution of stirring power between bulk flow and turbulent pulsation. Generally speaking, the power distribution of turbine-type Industrial Agitators is favorable for turbulent flow pulsation, while propeller-type Industrial Agitators are favorable for overall flow.
Here is the content list:
l The impedance principle of Industrial Agitators.
l The principle of magnetic coupling.
The stirring viscosity of different medium viscosities refers to the resistance of the fluid to the flow, which is defined as when the liquid flows at a speed of 1cm/s, the required shear stress on the plane per square centimeter is called dynamic viscosity. Viscosity is a property of a fluid. When the fluid flows in the pipeline, there are three states laminar flow, transitional flow, and turbulent flow. These three flow states also exist in the stirring equipment, and one of the main parameters that determine these states is the viscosity of the fluid. For low-viscosity media, the use of small-diameter, high-speed Industrial Agitators can drive the surrounding fluid circulation and travel to a distance. This is not the case for fluids with high viscosity media, which need to be directly driven by Industrial Agitators. Industrial Agitators Impellers for low and medium viscosity fluids include paddle, open turbine, propulsion, long thin-blade propeller, disc turbine, break-in, plate and frame paddle, three-blade back-curved, MIG type, etc. Impellers suitable for high-viscosity and ultra-high-viscosity fluids include ribbon impeller, screw type, anchor type, frame type, propeller type, etc. The viscosity of some fluids changes with the progress of the reaction, so it is necessary to use an impeller suitable for a wide range of viscosity, such as a pan-energy impeller.
Because Magnetic Agitators apply the principle of magnetic coupling, the stirring shaft is isolated from the drive motor, and the inner layer is driven by the outer layer of magnetic force, which acts on the sealing cover between the inner and outer magnetic steels, and is pressed with fastening bolts. When the drive motor drives the outer magnetic steel to rotate, the strong magnet will pass through the sealing cover and drive the inner magnetic steel. Because the inner magnetic steel is connected with the transmission shaft, the stirring effect is realized, which realizes the true sense of Static sealing, completely realizing the purpose of no leakage and high-pressure resistance. Through this reform, the production capacity can be improved, the loss caused by the mechanical seal can be reduced, and safe production can be realized. The magnetic coupling technology is adopted, which completely solves the pressure leakage and air leakage of the equipment under the condition of pressure operation, and realizes the real static seal. For the same type of Industrial Agitators, under the same conditions of power consumption, for Industrial Agitators with large diameters and low speeds, the power is mainly consumed in the overall flow, which is beneficial to macro mixing. Small diameter, high-speed Industrial Agitators, the power is mainly consumed by turbulent pulsation, which is conducive to micromixing. The scale-up of Industrial Agitators is a complex issue related to the technological process, so far it can only be scaled up through experience, and extrapolated to the industrial scale according to the scale-up criteria obtained.
