Method for detecting a turbine bearing mechanism

Abstract

The present application relates to a kind of steam turbine bearing mechanism detection methods, comprising the following steps: traction assembly and displacement sensor are installed in bearing mechanism;Hydraulic drive module is compressed elastic component by the traction assembly;The hydraulic strength of gradually lifting of the hydraulic drive module is detected by pressure sensor, the displacement value of the traction assembly is detected by the displacement sensor;When the displacement value change corresponding to the reference rise of the hydraulic strength is lower than the minimum limit, the hydraulic drive module is automatically stopped to lift the hydraulic strength, and the displacement value detected by the displacement sensor is regarded as S value.When it is found that the displacement value change corresponding to the reference rise is lower than the minimum limit, since the hydraulic drive module is automatically stopped to lift the hydraulic strength, the further deformation of the components around elastic component and traction assembly is limited, the components around elastic component and traction assembly are prevented from being pulled off, and the reliability of detection is ensured.
