High frequency discharge in water ring vacuum pump

Water ring vacuum pump for suction flammable and explosive gas, gas can also be used in addition to the dust, water cut and popular, but due to the equipment used for a long time will appear the phenomenon of high frequency discharge, this phenomenon will change the use efficiency of water ring vacuum pump, in order to equipment can run smoothly, need to know the high frequency discharge of water ring vacuum pump.
1. Since electron diffusion is faster than ion diffusion, positive potential appears at the axis and negative potential appears at the tube wall as a result. In this way, electrostatic field is generated from the water ring vacuum pump axis pointing at the tube wall. Therefore, there are two kinds of electric fields in the discharge tube, one is the eddy electric field around the magnetic field line, the other is the electrostatic field pointing to the wall from the axis. When these two fields are applied simultaneously, the electrons move around the axis and extend toward the wall of the tube, resulting in a series of concentric rings. Because the energy of electrons at different radii is different, the energy levels and the number of electrons excited are different, therefore the rings with different radii have different colors.
2, this water ring vacuum pump high frequency discharge, as long as there is a high frequency electric field can be formed, not necessarily to electrode, so generally known as non-polar discharge. Infinite discharge can be formed not only under alternating electric field but also under alternating magnetic field.
3. When the frequency is low and the amplitude of harmonic vibration is much larger than the distance between the two poles, the electrons in the water ring vacuum pump go through the whole process of collapse, discharge and extinction in each half cycle, and the discharge situation at this time is the same as the dc situation. At higher frequencies, where the amplitude of the harmonic vibration is much smaller than the distance between the poles, the ionization capacity of the electrons is greatly enhanced by the constant movement of the electrons back and forth.
Therefore, it can be known that in the use of water ring vacuum pump, due to the different diffusion speed of electrons and ions, the electrons keep moving to strengthen the ionization capacity, thus forming the high-frequency discharge phenomenon. This phenomenon can effectively reduce the power consumption of water ring vacuum pump, reduce the enterprise cost, and promote the use of equipment.
