适用于压水堆压力容器密封面研磨的水平仪套装设计
|
摘要
结合压水型反应堆压力容器密封面研磨实践,设计了一套适于测量压力容器密封面研磨过程中水平度测量的水平仪套装装置。从技术指标、设计方案、技术创新、应用推广等方面对水平仪套装进行了分析说明。该水平仪套装因纯机械结构、体积小、质量轻等特征,满足了压力容器研磨过程中的使用要求;采用间接测量的方式,避免了对已研磨密封面的二次伤害;采用螺旋测微仪结合千分表的测量方式,提高了水平仪套装的测量精度,保证了反应堆的密封性及安全性;采用旋转螺旋测微仪调整高度代替调整垫片的方式提高了找平效率,缩短了现场工作时间,降低了工作人员受辐射的剂量。
In this paper, a set of horizontal instrument for measuring the water level of pressure vessel is designed. From the technical index, the design plan, the technical innovation, the application and so on, the horizontal instrument is analyzed. Due to the characteristics of pure mechanical structure, small size and light weight, the horizontal instrument set meets the requirements of the use of pressure vessel grinding process. Indirect measurement is adopted to avoid the secondary injury to the ground cover. The micrometer is used to improve the measurement precision of the horizontal instrument set, and the sealing and safety of the reactor are guaranteed. The method of adjusting height instead of adjusting gasket by rotating screw micrometer improved the leveling efficiency, shortened the working time on site and reduced the radiation dose of the staff.
