The Effects of Impeller Diameter | Sepro Mixing

- Not having the right impeller diameter is a common cause of agitator failure. In our latest video, we put 3 different impeller diameters to the test to see which is best at successfully suspending solids!

A very interesting demonstration. I would like to see what happens when the oversize impeller is operated in the opposite direction. i.e. Up-flow, rather than down-flow
Distances of impellers from bottom must be considered
Hydrofoil are not so sensitive to that
Thank you for very useful video! But what's about liquid emulsions? Or about solid particles that are less dense, than water medium?
Yess I have the same doubt ! The density of the liquid being handled could have been a parameter to determine this ratio as well .
For liquid emulsions and foam use a sawtooth (Cowles type)
Why are they placed with different distance to the floor? I mean, if you shuv number 1 down at the same level as number 4, wouldnt that affect the results dramatically?
No because hydrofoil is slightly affected by the clearance
i love u i have been finding a solution for an hour straight
Oh god. How beautiful is this.
wow thanks! from Indonesia
Could you explain how did you get the power draw? Speed x Diameter, ejm. 73mm x 1070 rpm = 3.71 W ?
You can calculate P as power number(for hydrofoil is 0.3)*rotational speed^3*diameter^5*density of fluid
There is a large impeller spacing from reactor bottom..
Bless you
Excelente ,mil gracias .
what is DT ratio?
Whats the effects if Tank is a Square Plan Shape (Instead of Circular)
Fillets of material will build up in the corners. Circular tanks are preferred when possible.
what is reduction ratio?
What kind of suspensions do you use?
I'm sure the liquid is just water and the particles are plastic only slightly heavier than water. For a similar demonstration, I bought plastic pearls that are sold in toy shops.
Thí nghiệm này sai, khoảng cách từ cánh khuấy tới đáy bể phải giống nhau thì chúng ta mới có thể so sánh. Ở bình thứ 3 và 4, khoảng cách là quá xa. Trong các thiết kế bồn chuyên nghiệp, tỉ lệ là 0.3. Với tỉ lệ 0.4 chúng ta sẽ phải chọn Motor gấp 5 lần công suất.
Sir what about the density of liquid? Doesn't it affect the ratio as well ?
