position for future reference. Installation using special lifting pole rotor 6.4.4.6 rotor lift, box spirit level to check the rotor axis neck of Yang, on both sides of the rotor should be lateral raises and numerical deviation of ≤ 0.10MM, qualified before the official lifting. Hoisting of the rotor dynamic and static clearance should be measured, rotors check clearance to prevent rotor colliding. 6.4.4.7 stationary blade carrier, diaphragm and sealing upper cylinder on the inside and install the mounting bolts, bolts and bolt holes in the surface should be coated with molybdenum disulfide. Follow the manufacturers stamp marked to install good sealing ring and spring. Check the sealing ring and spring plate, shall conform to the technical requirements manufacturers drawings. Bolt: ... Measurement with measurement tools, special tools, temporary connection bolts and connection tool equipped and in good condition. The rotor shaft to have fixed, such as thrust, bearing plates fixed installation, in case of wear of the rotor is too large. The coupling gasket check measurements: measured data processing according to gasket, clean the coupling gasket surface clean and Burr-free, check the coupling gasket thickness data, shim thickness deviation of ≤ 0.02mm, parallel degree deviation of ≤ 0.02mm. Coupling temporary bolts ready: preparing 4-8 bolt diameter coupling bolt hole diameter 0.5-1.0mm. 6.4.5.2 shaft coupling 6.4.5.2.1 General requirements in both the relative position of the flange according to the manufacturers mark, if there is no mark, two flange scoop bias complement each other and take care of the bolt hole alignment, hit the mark as basis for alignment and coupling is finally being joined. Each measurement in the two couplings along position for future reference. Installation using special lifting pole rotor 6.4.4.6 rotor lift, box spirit level to check the rotor axis neck of Yang, on both sides of the rotor should be lateral raises
