Water ring vacuum pump is a new type of industrial mechanical equipment, which has been well received in many aspects. How much do you know about this kind of equipment? In order to better understand this product, the following article explains the distillation pressure of this equipment:
1. The common vacuum distillation process of water ring vacuum pump is mostly operated in the pressure range above 104pa. The mechanism of vacuum distillation is similar to that of atmospheric distillation, and the form of atmospheric distillation device is basically available.
2. The crude vacuum distillation pressure range is 1.o * 104pa-2.7x102pa, and the gas flow is viscous. It is easy to carry out distillation operation in this pressure range.
3. The pressure range of low vacuum distillation is 2.7 * 102pa-1.opa. At this time, the gas is close to the transition flow state, which has strict requirements for the selection, design, manufacture, installation and operation of vacuum distillation device.
4. The pressure range of excimer distillation is 1.0-1.0 * 10-2Pa. At this time, the average free path of gas molecules is similar to the size of the distiller, and the gas is in the state of transition flow.
5. The operating pressure of molecular distillation is below 1.33 * 10-2Pa. In the molecular distillation or quasi molecular distillation device, the flow of gas is the free movement of molecules, that is to say, the collision and interference of other molecules in the system can be ignored. At this time, the distillation process is dominated by the evaporation from the liquid surface.
The introduction of the distillation pressure of the water ring vacuum pump, as well as the various ranges, has been explained in detail in this paper. If you are interested in this knowledge, you can generally understand it. After all, you can understand more about the product knowledge, so as to facilitate your operation and use. I hope you will pay more attention.
