First, the rotor is an important part of the vacuum pump. For the water ring vacuum pump, the designed rotor has the form of geometric symmetry. The advantage of this design in the use process is that the vibration is relatively small and the operation is relatively stable.
Second, there is a gap between the rotors and between the rotors and the shell, so that in the process of use, there is no need to use lubricating oil, but the friction is also very low. In this way, the driving power is greatly reduced to achieve the purpose of high-speed operation.
Third, the water ring vacuum pump cavity not only does not have the existence of compression, also does not install the use of exhaust valve. In this way, the design structure is simple and compact, so that once there is dust or water vapor in the extracted gas, it will not affect the use.
Finally, there are some other features of water ring vacuum pump, and the existence of each feature enhances the use value of water ring vacuum pump, therefore, such a vacuum pump has been the most possible use.
