Abstract
    In our country,the water-ring vacuum pump as a kind of pumping vacuum equipment began to be used in condenser of heatpower station in the mid of 1980s.Because of the complicated thermodynamic properties inside the condenser,the type-selective calculation of water-ring vacuum pump is allowed to be different from that in common use.
