| Abstract: | The degree of vacuum in steam turbines has direct influence on its economical efficiency.The leaking air will decrease the vacuum degree of condenser and it is one of the major factors that will affect the vacuum of direct air-cooling unit.As an important method for inspecting leakage,vacuum tightness test can be used to identify the state of condenser and so that some corresponding measures will be taken on leakage points.This paper presents the mathematical model of vacuum tightness for air-cooled condens... |
