The device comprises a heat exchanger tube plate, heat transfer tubes, guide rods, an airtight head mounting plate, guide strips and airtight heads; two ends of each heat transfer tube are in sealed connection with the heat exchanger tube plate; the guide rods are parallelly arranged on the heat exchanger tube plate along a first direction; the airtight head mounting plate is movably connected with the guide rods; the guide strips are arranged on the airtight head mounting plate and are parallel to the heat exchanger tube plate along a second direction; and the airtight heads are movably connected with the guide strips.
Description
technical field [0001] The invention relates to a sealing detection device, and in particular to a heat exchange tube sealing detection device of a heat exchanger. Background technique [0002] The connection and sealing ability of the heat exchange tube and the tube sheet of the heat exchanger is an important indicator of the quality of the heat exchanger. The sealing performance of the heat exchange tube and the tube sheet is not good, which makes the heat exchanger in use, especially in harsh environments , will be a leak point or leak surface, so after the production of the heat exchanger is completed, the sealing performance test must be carried out. [0003] The traditional detection method is to perform a pressure test on the heat exchange tube and the tube sheet as a whole after the production of the heat exchanger is completed, and then look for the leak point. However, during the overall pressure test process, the connection ends of the tube sheet and the heat exc...
