Small mixer truck is determined by multiple parameters, and it is impossible to describe a small mixer truck with any single parameter. The following minor editor will explain this aspect:
Shaft power (P), blade discharge (Q), pressure head (H), blade diameter (D) and mixing speed (N) are five basic parameters to describe a small mixer truck. The discharge volume of the blade is in direct proportion to the flow criterion of the blade itself, the first power of the blade speed and the third power of the blade diameter.
The shaft power consumed by stirring is proportional to the specific gravity of the fluid, the power criterion of the blade itself, the third power of the speed and the fifth power of the blade diameter.
Under the condition of a certain power and blade form, the liquid discharge (Q) and pressure head (H) of the blade can be adjusted by changing the matching of the diameter (D) and speed (N) of the blade, that is, the small mixer with large diameter blades and low speed (to ensure the same shaft power) will produce higher flow effect and lower pressure head, while the small diameter blades with high speed will produce higher pressure head and lower flow effect. In the stirred tank, the way to make the micro clusters collide with each other is to provide sufficient shear rate.
From the point of view of small mixer truck, it is the existence of fluid velocity difference that causes fluid layers to mix with each other. Therefore, all mixing processes always involve fluid shear rate.
Shear stress is a kind of force, which is the cause of bubble dispersion and droplet breakage in mixing applications. It should be pointed out that the shear rate at each point of the fluid in the whole stirred tank is not the same.
That's enough to explain that small mixers are determined by multiple parameters. If you have anything to ask, please come to our website http://www.zkzsljbc.com consulting service
