Do you know how to buy an overhead mixer?

Overhead mixer as a basic laboratory equipment, suitable for biological, physical and chemical, cosmetics, health care products, food and other liquid / liquid mixing, emulsification, liquid / solid powder dispersion, 

slurry experimental field. But do you know how to buy overhead mixer? Here let me tell you in detail, together with a look at it.

Overhead mixers are designed for application environments such as schools, laboratories and factories for mixing of viscous substances.

Selection of stirring version needs to pay attention to the following requirements for selection

1. Select the stirrer type according to the process conditions, stirring purpose and requirements. When selecting the stirrer type, you should fully grasp the dynamic characteristics of the stirrer and the causal 

relationship between the flow state generated by the stirrer during the stirring process and the various stirring purposes.

2. According to the determined stirrer type and the flow state generated by the stirrer in the stirring process, the process of mixing time, settling speed, dispersion control requirements, through experimental means 

and computer simulation design to determine the motor power, stirring speed, stirrer diameter.

3. In accordance with the motor power, stirring speed and process conditions, select and determine the reducer model from the reducer selection table. If the reducer is selected according to the actual working torque, 

the actual working torque should be less than the allowable torque of the reducer.

4. Select the frame and coupling of the same type and specification as d according to the output shaft head d of the reducer and the support method of the mixing shaft system.

5. Select the shaft seal type according to the size of the agitating head do of the frame, installation space and working pressure and working temperature.

6. According to the installation form and structure requirements, design and select the structure type of mixing shaft, and check its strength and rigidity. If the design is based on rigid shaft, n/nk≤0.7 under the condition 

of strength; if the design is based on flexible shaft, n/nk>=1.3 under the condition of strength.

7.According to the nominal heart DN of the frame, the type of shaft and pressure level of the mixing shaft, choose to install the bottom cover, flange base or flange.

8. According to the support and anti-vibration conditions, determine whether to configure the auxiliary support.

According to the above conditions to choose, I believe that you can choose the right overhead mixer, to add color to your work.
