[0041] Step 1: Pre-Balance the Rotor
[0042] Install the rotor on the balancing machine, adopt single-stage balancing of turntables at all levels, group and combine balancing, and repeat balancing. The specific steps are as follows:
[0043] 1) The final dynamic balance of the primary and secondary rotors: the initial unbalance of each correction plane of the initial primary and secondary rotors is 513.8g.mm and 357.5g.mm respectively. By adjusting the position of the primary and secondary rotor blades, each The unbalance amounts of the two correction planes are 186.7g.mm and 150.4g.mm respectively.
[0044] 2) Balance the third-stage disc assembly: statically balance the third-stage disc assembly, and adjust the position of the third-stage blades so that the unbalance of the correction plane is 184.3g.mm.
[0045] 3) Rotor initial leveling: The high-pressure compressor rotor installed with 1-3 blades is dynamically balanced, and the initial unbalance of each correction plan...
