Turbine dividing plate is mainly made up of partition body, multiple guide vanes and dividing plate outer shroud, and the guide vane is mainly by inner platform, blade and outer
Listrium is formed；The dividing plate assembly technology includes following technical measures：
- the listrium fitting surface of each guide vane processed into smooth, welding divided edge structure；
- by the inner platform of each guide vane successively brush in the periphery of partition body, each guide vane is formed leaf in the periphery of partition body
Grid, partition body and leaf grating composition brush assembly；
- dividing plate outer shroud and brush assembly be subjected to brush processing；
- assemble the good dividing plate outer shroud of brush on brush assembly with hot jacket assembly method, the dividing plate outer shroud is in brush
At the curtain plate of the leaf grating of assembly, partition board of steam turbine is obtained.
One of preferably, the periphery of the partition body has raised positioning spigot, the inner edge of the guide vane
Brush of the plate in partition body periphery is to be used as benchmark using the raised positioning spigot in partition body periphery.
One of preferably, the magnitude of interference of the hot jacket assembling is 0~0.10mm.
One of preferably, the hot jacket temperature of the hot jacket assembling is 150~250 DEG C, soaking time 3h.
The method have the benefit that：
1. the present invention need not open up welding groove structure on the listrium fitting surface of each guide vane, soldering need not be also carried out,
Mounting technology difficulty is small, so that whole assembly period significantly shortens, efficiency of assembling is largely increased, and manufacturing cost is obtained
To being greatly reduced；In addition, the problem of above-mentioned assembly technology is not in leaf grating deformation substantially, fitted position is readily obtained guarantee,
So that assembly precision is reliably ensured, Forming Quality is high；
2. brush of each guide vane of the present invention on partition body is reliable, accurate；In addition, the hot jacket assembly method energy of the present invention
Enough ensure that assembly precision is reliably ensured, can further improve molding assembly quality.
