| Abstract: | Based on the detailed introduction of the working principle,the whole process of the cavitation erosion which is the main reason for the decrease of the service life of the water-ring vacuum pump system is analyzed in the paper.Two kinds of reconstruction schemes for the cooling water in the coolers and the working fluid in the vacuum pump are proposed,and the methods abandoned in the paper are also discussed to make a comparison. |
