Embodiment Construction
[0011] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0012] The reactor control rod drive mechanism with an adjustable magnetic damper provided by the present invention consists of an adjustable magnetic damper 1, a motor 2, a gear reduction mechanism 3, a sprocket device 4, a rod position measurement system 5 and a drive mechanism bracket 6 and other parts. The adjustable magnetic damper 1 includes: a moving disk 7, an upper disk 8, a lower disk 9, an upper bearing seat 10, an adjusting screw 11, a locking screw 12, a magnetic block 13 and the like. The magnetic damper 1 is installed on the outer top of the driving mechanism, and is connected with the motor 2 by a shaft sleeve 14 . In order to make the structure of the magnetic damper more compact, not only samarium cobalt permanent magnet material Sm is housed on the lower disk 9 2 (Co, Cu, Fe, Zr) 17 The magnetic block 13 made is also equipped with a bear...
