Rotary vane vacuum pumps _ of the satellite vacuum test

between satellite earth station is achieved in the field of communications satellite and earth station and spacecraft, is mainly used in communications, mobile communications, broadcasting, maritime communication, communication between the tracking and data relay, etc. In this critical and demanding applications, communications satellites, not only need higher professional skills as the support, vacuum technology is also a full range of supply chain. In its development process strictly rotary vane vacuum pumps play a crucial role, rotary vane vacuum pumps can be used in the satellite test, in order to help achieve global communications. This paper in the introduction to the rotary-vane vacuum pump application in satellite test.

rotary vane vacuum pumps than other domestic product advantage:

1. Easy installation, simple maintenance;

2。 A rotary vane vacuum pumps gas ballast valve set, in addition to a small amount of water vapor can be inhaled;

3。 Final high vacuum rotary vane vacuum pump;

4。 Forced to enter the oil content and lubrication performance reliable enough;

5。 With automatic protection back double insurance;

6。 Inlet pressure 1. 33 x 10 pa remains continuous operation time;

7。 No leakage, no oil, no environmental pollution.

the number of orbit communications satellites into space is increasing. As mobile method, using the so-called modern spacecraft electric propulsion, among them, the ionized particles described in ion thruster speed. These engines usually xenon gas as fuel, rotary vane vacuum pump is a huge challenge, because they need to keep within the scope of high vacuum pressure, and high energy ions with large flow injection. Xenon gas water pump, in order to provide the electric propulsion system to optimize the delivery and simple solution, and mass production test these devices.

these Spaces can start testing may last for months, and to provide a constant performance, this work requires real expertise needed for rotary vane vacuum pump. Vacuum turbo molecular pump and a high vacuum to remove unwanted air first. Then, would be frozen cold plate can efficiently light-emitting xenon, the degree of vacuum required.

import rotary vane vacuum pumps suitable for the occasion:

gas type: normal no other clean and dry air mixture, make its containing dust and other moisture in the air.

work requirements: inlet pressure continuous working time is more than 6500 pa, not more than three minutes, to avoid the fuel injector pump damage.

requirements: in less than 1330 pa entrance pressure is allowed to run continuously for a long time.

the environment temperature, vacuum pump is generally in temperature is not lower than 5 ℃ and relative humidity of not more than 90%.

the satellite is widely used, such as scientific research, weather forecasting, Marine, military and aerospace. People around today most communications satellites using earth, makes communicate anywhere on earth. In fact, more than half of the space satellite is a communications satellite. In addition, no matter whether people realize this, satellite communications have been in all aspects of daily life has been associated with us. Therefore, rotary vane vacuum pump application in satellite test is also very important.
