Liquid Ring Vacuum Pump distillation pressure

Want to better use of a product would need to have a comprehensive understanding to it, the liquid ring vacuum pump is the same, in order to facilitate everyone to use and improve your product operation proficiency, the next is to introduce the  liquid ring vacuum pump pressure distillation knowledge, everyone can read once, will help to understand and use the product.

1. Common  liquid ring vacuum pump vacuum distillation process, most of which operate within the pressure range of more than 104Pa. The mechanism of vacuum distillation is similar to atmospheric distillation, and the form of atmospheric distillation is basically available.


2. The pressure range of the coarse vacuum distillation is 1.O*104Pa-2.7x102Pa, and the gas flow is viscous. It is easy to do distillation under this pressure range.


3. The pressure range of low vacuum distillation is 2.7* 102pa-1.OPa, the gas is close to the transition flow state, and there are strict requirements on the selection, design, manufacture, installation and operation of vacuum distillation apparatus.

4. The pressure range of quasi-molecular distillation is 1.0-1.0* 10-2pa. At this time, the average free path of the gas molecules is similar to the size of the distillator, and the gas is in a transition state.


5. Molecular distillation operation pressure is below 1.33* 10-2pa. In the molecular distillation or quasi molecular distillation device, the flow of the gas for the free movement of molecules, that is to say, you can ignore the other molecular collision and interference of the system, at this point, the distillation process governed by evaporation from the liquid surface.


Distillation of  liquid ring vacuum pump pressure, this paper has explained more clearly, in the later operation, we should according to the article explained the content of the general operation, know more about the knowledge of the product, as well as the operation of the product specifications, for their own operation is helpful.
