Embodiment Construction

[0027] Such as Figure 1 to Figure 9 As shown, a testing tool for the overall delivery module of a steam turbine includes a measuring tool; the measuring tool includes a mounting part 11 and a measuring part 12 perpendicular to each other, forming an L shape; there is a protruding notch 13 on the back of the mounting part 11 , and positioned on the end wall of the outer cylinder 8 through the seam 13; the seam 13 is matched with the concave groove on the end wall of the outer cylinder 8, and the matching accuracy is 0.05 mm to 0.15 mm. The outer surface of the measuring part 12 is a measuring surface 14 . The measuring tools are divided into three measuring tools on the turbine side and three measuring tools on the motor side. There are installation holes 15 on the installation part 11 of the measuring tool, and are fixed together with the outer cylinder 8 by bolts 7 .

[0028] The turbine-side measuring instruments include turbine-side measuring instruments I1-III3; the tur...

Abstract

The invention discloses a steam turbine overall delivery module detection tool which is characterized in that the detection tool comprises one or more measuring appliances; each measuring appliance comprises a mounting part and a measuring part which are perpendicular to each other and form an L shape; there is a protruding spigot on the back of each mounting part, and each mounting part is located on the end wall of an outer cylinder through the spigot; and the outer side face of each measuring part is a measuring face. By using the overall delivery module detection tool, the time for assembly on a power plant site can be greatly shortened, the assembly precision can be improved, and significant economic and social benefits can be brought to the power plant.

Description

technical field [0001] The invention relates to assembly and testing equipment for steam turbines, in particular to a testing tool for integral delivery modules of steam turbines. Background technique [0002] In order to shorten the on-site assembly time of power plants, improve assembly accuracy, and increase the market competitiveness of equipment manufacturers. Manufacturing plants have increasingly delivered large steam turbine high and medium pressure modules as a whole, that is, after the cylinder and rotor are assembled in the manufacturing plant, they are sent to the power plant as a whole, where they are connected with other parts as a whole. Due to the overall delivery, there is a possibility that the relative position of the turbine rotor and the outer cylinder may change during transportation. After the entire module is transported to the site, during the site installation process and when the unit is overhauled and adjusted in the future, it is necessary to en...
