Abstract

A nuclear evaporator heat transfer pipe inner hole crack detection device with convenient wire arrangement comprises a seat body and probes arranged on the seat body. The seat body is a cylinder, a first concave table board and a second concave table board are formed on the side face of the cylinder, the first concave table board is parallel to the second concave table board, the structure with cylindrical end faces at the two ends and the two parallel concave table boards in the middle is formed, five through holes are formed in the two parallel concave table boards and comprise two first through holes used for mounting crack detection point focusing probes, two second through holes used for mounting linear focusing probes and one third through hole used for mounting a thickness detecting point focusing probe, and a probe emission end is arranged on the second concave table board. The first concave table board face is provided with a wire arrangement hole communicated with the cylindrical end face at one end of the seat body. The nuclear evaporator heat transfer pipe inner hole crack detection device with convenient wire arrangement is located in a heat transfer pipe in the crack detection process, leading wires of the five probes are connected to the outside by penetrating through the wire arrangement hole, and therefore the interference of the leading wires to detection is avoided.

Description

Technical field [0001] The invention relates to a flaw detection device for the inner hole of a heat transfer tube of a nuclear power evaporator with convenient wiring. Background technique [0002] In recent years, nuclear power, as an efficient, clean and sustainable energy source, has once again received great attention and extensive attention from people. According to the current environmental situation and the needs of sustainable development, nuclear energy has become one of the most practical and important alternative energy sources for my country to ensure the security of energy supply and adjust the power structure, and it is an important part of my country's modern energy industry construction. [0003] The steam generator is the hub of the primary and secondary circuits of the pressurized water reactor nuclear power plant. The key equipment of the primary circuit system is to produce high-quality dry steam through the heat exchange of the tube bundle, and drive the steam...
