Example Embodiment

[0020] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0021] In the present application, the sealing front end device 1 is moved. After one end of the front end device is moved to a predetermined position, the cylinder of the vertical tube plate in the device is activated, and the "core" is inserted into the tube hole. After the detection is completed, the cylinder is lifted and removed from the tube. Board to move to the next position. PLC front-end control unit 2: used to control the movement of the mobile sealing fixture device and the vacuum system. Vacuum leak detector 3: Refers to the leak detector and related vacuu...

Abstract

The invention relates to an automatic crawling helium leakage detection system for a heat-exchanging tube and a caulk weld in a heat exchanger tube plate. The automatic crawl helium leakage detectionsystem comprises a movable sealing front end device, a PLC (Programmable Logic Controller) front end control unit, a vacuum leakage detection device and an industrial control computer, wherein one endof the movable sealing front end device is electrically connected with the PLC front end control unit; the other end of the movable sealing front end device is electrically connected with the vacuumleakage detection device and the industrial control computer respectively; and the movable sealing front end device comprises a first motor, a slide plate, a first slide block, an integral detection assembly, a second slide block and a branch detection assembly. The automatic crawling helium leakage detection system for the heat-exchanging tube and the caulk weld in the heat exchanger tube plate has the advantages of simple structure, capability of keeping detection consistency and accuracy, higher integral working efficiency, saving of manpower and material resources and higher integral detection efficiency, and can be conveniently popularized and used.

Description

technical field [0001] The invention relates to the technical field of automatic air tightness detection, in particular to an automatic crawling helium leak detection system for heat exchange tubes and sealing welds in heat exchanger tube sheets. Background technique [0002] With the continuous development of society, heat exchangers have been widely used in various industries. During the production and manufacturing process of heat exchangers, it is necessary to carry out air tightness testing on the heat exchange tubes and their welds. At present, there are two main methods for leak detection of heat exchange tubes and sealing welds in heat exchanger tube sheets. One is the pressure difference method, which forms a pressure difference between the inner and outer parts of the object to be tested, and smears soapy water on the parts that need to be tested. , the inspector judges whether there is a leak by observing the changes of soap bubbles; the second is the hand-held...
