1. According to the process conditions, mixing purpose and requirements, choose the type of agitator. When selecting the type of agitator, fully understand the dynamic characteristics of the agitator and the causal relationship between the flow state generated by the agitator during the mixing process and various mixing purposes. According to the determined type of agitator and the flow state generated by the agitator during the agitation process, the control requirements of the mixing time, the sedimentation speed and the dispersion degree are determined by the experimental means and the computer simulation design to determine the motor power and the stirring speed. , the diameter of the stirrer.
3. According to the motor power, stirring speed and process conditions, select the reducer model from the speed 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. According to the output shaft head d of the reducer and the agitator shaft support mode, select the frame and coupling of the same model and size as the d. 5. According to the frame abutment do size, installation and accommodation space, working pressure and working temperature Shaft seal type 6. According to the installation form and structural requirements, the design of the agitator shaft structure is selected and the strength and rigidity are checked.
If designed according to the rigid axis, n/nk≤0.7 under the condition of satisfying the strength
If designed according to the flexible axis, under the condition of strength, n/nk>=1.3
7. According to the nominal DN of the frame, the type of the axle of the agitator shaft and the pressure rating, choose to install the bottom cover, flange base or flange flange. 8. Determine whether to configure the auxiliary support according to the support and anti-vibration conditions.
In the above selection process, the combination and configuration of the stirring device can be referred to (the schematic diagram of the design of the stirring device design selection). The key dimension of the connection between the components in the configuration process is the size of the shaft head. The components with the same size of the shaft head can in principle be mutually Change, combination.
