Embodiment Construction
[0046] The present invention will be further described in detail through the drawings and examples below. Through these descriptions, the features and advantages of the present invention will become more apparent.
[0047] The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as superior or better than other embodiments. While various aspects of the embodiments are shown in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
[0048] The deep hole of the tube plate of nuclear power heat exchanger is an important manufacturing process of the heat exchanger. The tube plate hole is the weak link of the heat exchanger, especially the verticality of the tube hole, which directly affects the size of the secondary side hole bridge, which will directly affect the to the quality of the heat exchanger. Therefore...
