Abstract

Abstract

The insulating property of water medium affects the operation status of pulse power device, and air bubbles in water are the main factor causing breakdown of water medium. In order to remove air bubbles and dissolved gases in the water medium, the causes of air bubbles in the water medium are analyzed, and for the removal of body-phase air bubbles and surface adsorption air bubbles in the water medium, the methods of removing air bubbles by using vortex separators and reverse osmosis membranes are compared, and experimental research is carried out to study the performance of their air bubble removal. The results show that the vortex separator's low cyclonic strength leads to low separation efficiency, and the reverse osmosis membrane degassing makes the surface adsorbed bubbles re-dissolve by reducing the solubility of the gas in the water, and the separation efficiency is high, which can remove the gas bubbles and dissolved gases in the water, and it is of great significance for the stable operation of the pulsed power device.
