Reasonable choice of vacuum pump is very important

The most important problem to be solved in this work is vacuuming, that is, choosing a vacuum pump. The subsequent tests were conducted using an air dryer combination and a vacuum fitting. Ammunition packaging vacuum maintenance equipment is used for routine maintenance of various types of airborne guided missiles. Its main components are: automatic air dryer combination, single-stage rotary vane vacuum pump, electronic control part, pressure detection, remote control and quick connector. The automatic air dryer technology is used for the inflating part, so it is called an automatic air dryer combination here. An automatic air dryer is used to inflate and dehumidify the waveguide cavity to ensure normal operation of the radar feed line system. This technology is normative and mature. Air dryers have also been used to inflate the airframe and the vestibule room, and then pump air. The air dryer combines both air and air exhaust. Since vacuum cleaners (even the best vacuum cleaners) and air dryer combinations are not specialty products for vacuuming, the technical performance naturally falls short of the requirements.

Evacuation is completed by the XD series single-stage rotary vane vacuum pump, which is a purchased product and professional product. The ultimate pressure for vacuuming is 3 KPa, and an atmospheric pressure is about 100 KPa. When pumping, the two solenoid valves on the inflation line are closed, and the solenoid valve on the suction line opens. The vacuum pump will first extract the normal temperature and pressure air between the projectile and the projectile, and then stop working. Dry air is charged by a combination of an automatic air dryer and the packaging environment is dried. Next, the automatic air dryer combination stops working, the vacuum pump starts, the gas between the projectile and the projectile is taken out, the sealing is performed at any time, and the maintenance of one projectile is completed.
