Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the position of thickened blades in the current steam turbine blades in the whole circle of blades is manually fixed randomly, there is no accurate positioning and sorting method, and there is a problem of excessive concentration or dispersion in assembly, which is easy to cause problems in assembly. In order to solve the problem that the assembly gap cannot be ground, and then provide a steam turbine blade sorting method involving thickened steam turbine blades

specific Embodiment approach 1

[0105] Embodiment 1: Combining Figure 1-Figure 5 Describing the present embodiment, a steam turbine blade sorting method involving thickened steam turbine blades according to the present embodiment is performed according to the following steps:

[0106] Step 1. According to the product design requirements, determine the ratio of the number of thickened blades involved in the sorting to the total number of blades as A, where the total number of blades of this product is T, and the special blades (first and last blades, locking blades) The number is a; the number of ordinary leaves is b, b=T-n-a;

[0107] Step 2. According to the design requirements of the product, the thickened blades are arranged according to the principle of uniform distribution and the serial number is determined:

[0108] Among them, the number of thickened blades is n, which is obtained from step 1, and the number of thickened blades is n=T×A;

[0109] Then, the installation position numbers of the n th...

Abstract

The invention provides a turbine blade ordering method relating to turbine thickened blades and relates to a location and sort algorithm of turbine blades. At present, thickened blades in turbine blades are fixed randomly through manual work in an entire circle of blades, no accurate location and ordering method exists, over-concentrated problem or over-dispersive problem exists in assembling, and the problem that grinding of an assembling clearance in assembling is incapable is prone to occur, however, the turbine blade ordering method relating to the turbine thickened blades solves the above problems. The ordering method comprises the main steps: S1, confirming the number of the thickened blades of the products participating in ordering according to product design requirements, S2, arranging the thickened blades through an equally distributed principle and confirming the sequence numbers of the thickened blades, S3, confirming the installation site sequence numbers of numbers of the thickened blades and processing random numbers, S4, weighing the thickened blades, S5, ordering the thickened blades, S6, weighing ordinary blades, and S7, ordering the ordinary blades. The invention relates to turbine blade ordering of the thickened blades.

Description

technical field [0001] The invention relates to a steam turbine blade positioning and sorting algorithm, in particular to a steam turbine blade sorting method involving thickened steam turbine blades. Background technique [0002] Thickened steam turbine blades refer to special blades whose radial dimension is 0.20mm to 0.30mm thicker than ordinary blades, and is used for grinding the assembly gap during assembly. At present, the positions of the thickened blades of steam turbines in the whole circle of blades are fixed manually and randomly, and there is no accurate positioning and sorting method. There are problems of excessive concentration or dispersion in the assembly, which easily leads to the inability to grind the assembly gap during assembly. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to solve the problem that the position of the thickened blade in the current steam turbine blade in the entire circle of blades is fixed manually by ha...
