In order to better use a product, it is necessary to have a comprehensive understanding of it, as is the case with the water ring vacuum pump. Next, I will introduce the distillation pressure
knowledge of the water ring vacuum pump
to you. You can read it carefully, which will be helpful for your understanding and use of the product.
1, the common water ring vacuum pump vacuum distillation process, mostly in the 104Pa above the pressure range operation. The mechanism of vacuum distillation is similar to that of atmospheric distillation.
2. The crude vacuum distillation pressure ranges from 1.O* 104pa-2.7 x102Pa, and the gas flow is viscous. Distillation within this pressure range is easy to achieve.
3, the low vacuum distillation pressure range is 2.7* 102pa-1.OPa, at this time the gas close to the transition flow state, the vacuum distillation device selection, design, manufacturing, installation, operation and so on have relatively strict requirements.
4. The range of excimer distillation pressure is 1.0-1.0* 10-2pa. At this time, the average free path of gas molecules is close to the size of the distiller, and the gas presents a transitional flow state.
5. The operating pressure of molecular distillation is below 1.33* 10-2pa. In a molecular distillation or excimer distillation apparatus, the flow of gases is free movement of molecules, that is, collisions and disturbances of other molecules in the system can be ignored, and the distillation process is governed by evaporation from the liquid level.
About the water ring vacuum pump distillation pressure knowledge, explanation has been more detailed, you can generally understand, in the future operation and use, I hope that the content will give you help. Get practical operation meaning.
