The current common methods for leak detection of the condenser comprise a helium mass spectrometer leak detection technology and a film covering method. The helium mass spectrometer leak detection technology is a vacuum leak detection method, helium is sprayed at a suspected leakage part, the helium can be sucked at the leakage part and is finally discharged from a steam extractor, and the leakage is judged whether to exist at the outlet of the steam extractor through the reading change of a helium detector so as to determine the leakage position. In the film covering method, the plastic film is used for covering the pipe orifice of a suspicious leakage pipe with the film, and under the action of vacuum suction, if the heat exchange pipe leaks, the film is sunken inwards, and the position of the leakage pipe row is difficult to accurately judge due to the fog in the condenser. In the two methods, during leakage detection, workers need to enter the condenser through the manhole, and certain safety risk exists for the workers.
