Stainless steel stirrer is a device that enables forced convection and uniform mixing of liquid and gas media. It can often be seen in industrial production. Since various mixing processes need to be realized by different stainless steel agitators, when designing and selecting, first of all, according to the purpose and requirements of the mixing operation of the process, the mixer type, motor power, and mixing speed should be determined, and then the reducer should be selected. , frame, mixing shaft, shaft seal and other components. The specific steps and methods of the stainless steel mixer are as follows:
According to the process conditions, mixing purpose and requirements, select the stainless steel mixer type. When selecting the mixer type, you should fully grasp the dynamic characteristics of the mixer and the generated energy generated by the mixer during the mixing process. The causal relationship between the flow state and various stirring purposes.
According to the determined stainless steel mixer type and the flow state generated during the mixing process, as well as the process control requirements for mixing time, sedimentation speed, and dispersion, the motor power is determined through experimental means and computer simulation design , stirring speed, diameter of stainless steel stirrer.
According to the motor power, stirring speed and process conditions, select the reducer model from the reducer selection table. If the reducer is selected based on the actual working torque, the actual working torque should be less than the allowable torque of the reducer.
According to the output shaft head d of the reducer and the supporting method of the stirring shaft system, select the frame and coupling of the same model and specification as d.
Select the shaft seal type according to the d size of the mixing shaft head of the rack, installation and accommodation space, working pressure, and working temperature.
According to the installation form and structural requirements, design and select the mixing shaft structure type, and check its strength and stiffness.
If designed according to the rigid shaft, provided that the strength conditions are met
If designed according to the flexible shaft, provided that the strength conditions are met/=.
According to the nominal center size D of the frame, the mixing shaft Shaft type and pressure level, choose to install bottom cover, flange base or flange flange.
According to the support and anti-vibration conditions, determine whether to configure auxiliary supports.
In the above selection process, the combination and configuration of the stainless steel agitator can be referred to. The key dimension of the connection between the components during the configuration process is the shaft head size. In principle, the components with the same shaft head size can be interchanged and combined. .
