Vacuum pump can meet certain requirements during use, but in the production process, it needs to operate strictly in accordance with the operating regulations to achieve good results. Follow the Wholesale Rotary vane vacuum pump editor to understand the vacuum pump high-frequency discharge What are the reasons for the phenomenon?

Vacuum pump high-frequency discharge is the form of discharge caused when there is a high-frequency alternating electric field between two electrodes. When an alternating voltage is applied to both ends of the discharge tube, the electrons and positive ions in the gas will produce additional resonance under the action of the alternating electric field. Because the mass of positive ions is much larger than that of electrons, the resonance amplitude is very small. When the frequency is low and the amplitude of the resonance vibration is much larger than the distance between the two poles, the electron goes through the whole process of collapse, discharge, and extinguishment in each half cycle. The discharge situation at this time is the same as the DC situation. When the frequency is higher, the amplitude of the resonance vibration is much smaller than the distance between the two poles, as the electrons continue to move back and forth, their ionization ability will be greatly enhanced. Because the amplitude of the electronic resonance is very small, the number of electrons entering the electrode will be greatly reduced. In this way, it is ensured that the electrons for the self-sustained discharge of the gas will no longer be provided by the secondary electrons generated by the electrodes, but by the electrons generated by ionization when the electrons move back and forth. At this time, although a small amount of positive ions and photons bombard the electrode to generate secondary electrons, because the polarities of the two electrodes are constantly changing, the vibration direction of the secondary electrons is sometimes the same as the direction of the electron flow entering the electrode, sometimes opposite. Therefore, it is not good for ensuring self-sustainability conditions.
