Why Can't Vacuum Homogeneous Emulsifying Tank Run Idle

The vacuum homogenizing emulsifying tank is a high-performance homogenizing and emulsifying equipment used for continuous production or circulating processing of materials that need to be dispersed, emulsified, and broken. A few days ago, the editor of Zhonghao saw a question from a netizen on a forum, why can't the vacuum homogenizing emulsifying tank be idling? In response to this question, the following editor will give you specific instructions.

 

The vacuum homogeneous emulsifying tank is a process of efficiently, quickly and evenly bringing one phase or multiple phases (liquid, solid, gas) into another immiscible continuous phase (usually liquid). The principle is the high tangential velocity generated by the high speed of the rotor rotation and high frequency mechanical effects brought by the strong kinetic energy, so that the material is subjected to some comprehensive effects like strong mechanical and hydraulic shear, centrifugal extrusion, liquid layer friction, impact tearing and turbulence in the narrow gap between the stator and the rotor to form suspension (solid/liquid), emulsion (liquid/liquid) and foam (gas/liquid).

 

The part where the emulsification head stirring device on the emulsion tank is connected to the stator is equipped with copper sleeve bearings or bearings of other materials, and the rotation speed of the drive shaft is generally 2800 rpm. Due to the relative high-speed movement between the copper sleeve and the drive shaft, the friction will generate a very high temperature. If there is no lubricant between the copper sleeve and the shaft, the copper sleeve and the shaft will expand due to the high temperature, thus locking, the copper sleeve and the shaft will be scrapped as a result. When the emulsification head is immersed in the solution, the solution will enter the gap between the copper sleeve and the bearing, thereby providing lubrication.

 

The above is the main reason why the vacuum homogeneous emulsifying tank cannot be idling. Therefore, we often see in the operating instructions or warning signs of the vacuum homogeneous emulsifying tank: the vacuum homogeneous emulsifying tank is strictly prohibited from idling. Here, the editor reminds everyone that when operating the emulsifying tank, the emulsification head must be immersed by the material before starting to work.
