FIELD: power engineering.SUBSTANCE: support stand (430) for a steam turbine diaphragm comprises the main vertical part (435) with a bulge (447), which passes from the specified part (435) substantially perpendicular to it. The bulge comprises the first bulge, stretching from the upper end of the main vertical part (435), and the second bulge stretching from the area near the lower end of the main vertical part (435). The first bulge is at a certain distance from the second bulge. The first and second bulges are designed for coupling with an appropriate slot (450), made in the turbine diaphragm. In the bulges there is a hole (455), which passes via them vertically and is designed to place a fastening element (460), stretching via the first and second bulges (447) to ensure vertical attachment of the main vertical part (435) and specified bulges (447) to the turbine diaphragm.EFFECT: reduced duration and cost of maintenance cycle, since it provides for possibility of access for extraction of a lower half (410) of the diaphragm for maintenance without rotor removal.9 cl, 7 dwg |
