Vacuum Pump System in Electric Vacuum Industry

Because the working principle of various electric vacuum devices is based on electric field and magnetic field to control the movement of electrons in space so as to achieve the purposes of amplification, oscillation and image display. Therefore, the vacuum pump system can prevent the collision between electrons and gas molecules, ensure the movement law of electrons in space, avoid cathodic oxidation poisoning of emitted hot electrons, pump electronic devices into different vacuum required by different electronic vacuum devices, and ensure the normal operation of electronic devices.

At present, the main electrovacuum devices consumed in the electrovacuum industry are various kinds of electronic tubes (rectifier, transmitter, receiver, klystron, traveling wave tube, magnetron, photoelectric tube, etc.); various ion tubes (pump-arc rectifier, ignition tube, counter, thyratron, noise tube, radar wire switch, etc.);（ Oscilloscope, vidicon, kinescope, X-ray tube, image converter, etc.); various electric light source tubes (illumination lamp, spectral lamp, instrument lamp, etc.) and neutron tube, electron diffractometer, electron microscope, X-ray microscope, particle accelerator, mass spectrometer, nuclear radiation spectrometer, gas laser and electron in vacuum application Beam stop degassing, smelting, regional purification, condensation and drilling of refractory metals and media, grooving cutting, evaporation of radioactive isotopes, welding of refractory metals and many other aspects. These electronic devices and processes play an obvious role in modern science and modern industrial consumption.
