Detection system and detection method for accurately positioning leakage direction of condenser titanium pipe

Abstract

The invention discloses a detection system and a detection method for accurately positioning the leakage direction of a condenser titanium pipe. A detection belt fixing mechanism comprises a clampingplate, the inner side of the clamping plate is provided with a clamping groove for placing a detection belt, and the parts, located at the front side and the rear side of the clamping groove, of the clamping plate are rotatably connected with pressing wheels. The invention relates to the technical field of condensers. According to the detection system and the detection method for accurately positioning the leakage position of a condenser titanium pipe, the detection belt is rolled up to sleeve a pipeline and is fixed by the detection belt fixing mechanism, when the detection belt is pulled topass through the surface of the pipeline, the pipeline can be comprehensively detected, whether there is a leakage position or not is judged, if gas leaks, powder flies out of the surface of the detection belt, the leakage position can be visually seen, marking is convenient, positioning is accurate, the detection belt is fixed conveniently through the detection belt fixing mechanism, and the system can adapt to pipelines with different diameters has no limit on the variety of leaked gas, and is of high universality.

Description

technical field [0001] The invention relates to the technical field of condensers, in particular to a detection system and a detection method for precisely locating the leakage position of a titanium tube of a condenser. Background technique [0002] The condenser is a heat exchanger that condenses the exhaust steam of the steam turbine into water, also known as the rehydrator. Condensers are mainly used in steam turbine power plants and are divided into water-cooled condensers and air-cooled condensers. According to different steam condensation methods, condensers can be divided into two types: surface type (also called partition type) and mixed type (also called contact type). In a surface condenser, vapor separated from the cooling medium is condensed to liquid on cooling walls (usually metal tubes). The cooling medium can be water or air. Water-cooled surface condensers are divided into two types, single-flow and double-flow, according to the flow of cooling water. I...
