5.3　Installation of the Machine Train in Position

5.3.1　The machine train with individual delivery of machine and baseplate shall be set in position in accordance with the following requirements：

a）Clean the contact surface between the machine and baseplate；

b）Use 0.05mm feeler to check the contact surface between the machine and baseplate.The inserted depth shall not be over 1/4 contact surface width and support surface contacted tightly；

c）A complete stainless adjusting pad which total thickness is between 3mm-5mm，shall be installed between gearbox，motor and baseplate support surface.

d）Symmetrically fasten the connecting bolts between machine and baseplate.The radial clearance between bolt and hole shall be in conformity with the provisions of product technical documents.Check the vertical displacement of the support by means of the dial indicator.After loosening bolt，the displacement shall not be over 0.05mm；

e）The transverse level deviation of the machine shall be less than 0.10mm/m and longitudinal level shall meet the requirement of alignment curve in cold state.

5.3.2　Taking the gearbox as the benchmark to align the machine train，the measuring position should be selected in accordance with the following requirements：

a）Longitudinal level measuring point is on bearing saddle bore，journal or the specially processed surface specified by manufacturer；

b）The transverse level measuring point is on the split of the machine body，the split of bearing seat or specially processed surface specified by manufacturer.

5.3.3　The machine train with integrated delivery of machine and baseplate shall be set in position in accordance with the following requirements：

a）Clean the rust and rust protective oil on the baseplate of the equipment；

b）The allowable deviation of the longitudinal and transverse axis is 5mm and that of the elevation is within±5mm；

c）The transverse level deviation of the machine shall be less than 0.10mm/m and longitudinal level shall meet the requirement of alignment curve in cold state；

d）Tighten anchor bolts symmetrically and evenly.

5.3.4　The fit clearance between guide key of gearbox and casing shall conform to the product technical documents.If required by the designer or manufacturer，a disassembling inspection shall be implemented as per Chapter 6.

5.3.5　AV type axial compressor，if supplied in sections，shall be assembled and put in position in accordance with Chapter 7.

5.3.6　Flue gas expander，if supplied in sections，shall be assembled and put in position in accordance with Chapter 8.
