Technical Problem

[0005]本发明实施例提供一种静子叶片排设计方法和静子叶片排，可以改善静子进口流场周向不均匀的问题

Benefits of technology

[0020]基于上述技术方案，本发明提供的设计方法先确定基准叶片，然后选择参考叶片，确定基本单元，并以参考叶片为基准，通过旋转基本单元中的其他静子叶片调节其与基准叶片的相对位置，然后按照对基本单元的调节方法，调节基本单元之外的其他静子叶片和对应的支板叶片的相对位置，从而得到新的静子叶片排布，在新的静子叶片排布中，静子叶片和基准叶片之间的相对位置可以根据需要进行调节，因此有利于降低静子进口流场的周向不均匀性。

Abstract

The application relates to a stator blade row design method and a stator blade row, wherein the stator blade row design method comprises the following steps: providing n stator blades (10) arranged uniformly in the circumferential direction and m diaphragm blades (20) of an intermediate casing arranged uniformly in the circumferential direction; taking one diaphragm blade (20) as a reference blade (21), selecting the stator blade (10) closest to the reference blade (21) as a reference blade (11), and taking a stator blades (10) symmetrically arranged on both sides of the reference blade (11) and the reference blade (11) as a basic unit, wherein a+1=[n / m]; rotating the a stator blades (10) in the basic unit with the reference blade (11) as a reference to adjust the relative positions of the other stator blades (10) in the basic unit and the reference blade (21); and adjusting the positions of the stator blades (10) corresponding to the other diaphragm blades (20) according to the adjustment method of the basic unit.
