Why can't the vacuum homogenizing emulsifier run idly

The vacuum homogenizing emulsifier 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. Some users ask: Can the vacuum homogenizing emulsifier run idly? In this regard, we will give you a specific explanation.

The vacuum homogenizing emulsifier is a process of efficiently, quickly and evenly inserting one phase or multiple phases (liquid, solid, gas) into another immiscible continuous phase (usually liquid). The principle is the strong kinetic energy brought by the high tangential speed and high frequency mechanical effect produced by the high-speed rotation of the rotor, so that the material is subjected to strong mechanical and hydraulic shear, centrifugal extrusion, and liquid layer friction in the narrow gap between the stator and the rotor. , Impact tearing and turbulence, etc., to form suspension (solid/liquid), emulsion (liquid/liquid) and foam (gas/liquid).

The part where the emulsifying head stirring device on the emulsifying machine connects with 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 relatively 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 The shaft will be scrapped as a result. When the emulsifying 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 homogenizing emulsifier cannot run idly. Usually, the operating instructions or warning signs of the vacuum homogenizing emulsifier will state that the vacuum homogenizing emulsifier is strictly prohibited from idling.
