Abstract
On the basis of the experimental data tested on a N125MW unit
the rules of movement between the operating force on HIP cylinder caused by guide tube and extraction tube system and the conditions is found.The reasons of HIP cylinder offset are analyzed. Consequently
a non-displacement device is designed and fixed.The metrical data and the comparative investigation of the experiment results proved that this device is effective in preventing the cylinder’s offset. The treatment proposed in this paper is suggestive for similar problems in power plants.
