Vacuum system in aviation industry
The experimental content of the main simulator and its vacuum requirement are very important in the aerospace industry. Generally speaking, Shanghai EVP vacuum pump recommends the application of vacuum system in the aerospace industry.
Vacuum technology and space technology are closely related to the main link of space environment simulation, because launch vehicles, artificial satellites, manned spacecraft, space stations, space probes and space shuttles and other space vehicles, in the process of space flight, are carried out in the natural vacuum of the universe. Therefore, they are not only directly affected by the space vacuum environment, but also by solar radiation, charged particles and temperature. These factors will cause material performance changes or damage; instrument sensitivity failure, which will damage the work of these aircraft, and even cause astronauts’casualties.
Therefore, it is very necessary to establish a space simulation experimental device on the ground to simulate the space environment. Because it’s only through ground simulation experiments before all kinds of aircraft go to heaven. Only by mastering the conditions and characteristics of spacecraft working in space and eliminating various hidden dangers in flight can the safety of spacecraft and astronauts be ensured. In order to meet these requirements, many simulation devices have been built on the ground.
JZPS Roots-Liquid Ring Vacuum System
vacuum system advantages :
1. High vacuum limit and long-term stability of vacuum.
2. The pumping rate is high under higher vacuum.
3. The motor has low power and low energy consumption.
4. Because there is no oil lubrication in the overflow part of the vacuum system, after installing the exhaust gas collecting device at the exhaust port of the unit, it can collect gases such as benzene and toluene which can not be solidified and compressed in the high vacuum system.
5. No secondary water pollution, reduce the pressure of pollution control.
