Abstract:

The common layout of the rotary compensator on the pipe gallery is introduced. The relationship between the rotation angle of the rotary compensator and the length of rotating arm as well as the thermal displacement of the main pipe is analyzed through the simplified motion model of the rotary compensator. Through the simplified mechanical model of the rotary compensator, the influencing factors of the thrust force of the pipe-fixing bracket and the selection principle of the arm length of the rotary compensator, as well as the design problem of the pipe bracket using rotary compensator are analyzed.

Keywords: rotatory compensator / length of rotating arm / the thermal displacement / stress analysis
