摘要
汽轮机转子中心孔超声检测工作越来越受到电力工业运行部门的重视,因为用于制造转子的大锻件的中心部位常含较多缺陷,开中心孔后,靠近中心孔壁处常残留一些缺陷。有的转子甚至在离中心孔较远处也有较多缺陷。为此研制了ZZC-1型转子中心孔超声检测装置。本文叙述了该装置的设计原理、主要技术性能及现场应用情况。
Turbine rotor bore inspection has now been recieved more and more attention from power utilities. That is because there often exist a number of defects in the centre part of forging rotor, some may remain on the inner wall of rotor bore and some far from it after machining. To solve this problem, a ZZC—1 type bore inspection device has been developed. Presented in this paper are the design principle, technical featutes and on—site application.
