Force Measurement and Adjustment of Rigid Support Thrust Tile for Hydro-Generator
Rigid support structure is a widely used structure in hydro generator thrust bearing,this kind of support structure can not realise the automatic adjustment of the force of each thrust tile,and needs to be measured and adjusted manually.The purpose of this paper is to study the measurement and adjustment method of rigidly supported thrust tile force,in order to improve the efficiency of thrust tile installation and maintenance.The simulation of thrust tile force can be measured by using the braking air brake to jack up and down the rotating part of the unit to simulate the state of thrust tile without force and with force,and by measuring the displacement difference of the measuring rod of the weight-resisting bolt in the 2 states with the tools such as the percentage meter.According to the force data of all thrust tiles,through calculation,rotating the weight-resistant bolt under the pallet,it can drive the thrust tile up or down,and realise the adjustment of the force.With this method,the force data of the thrust tiles can be measured accurately and the force can be adjusted to the standard range efficiently.
