Abstract

The invention discloses a guide vane angle checking device. The device comprises a seat body, a bracket extending outwards from the seat body, and a measuring scale rotationally connected to one end of the bracket, wherein one end of the bracket is connected with the seat body, the other end of the bracket is rotatably connected with the measuring ruler, a dial is arranged at the rotary joint of the measuring ruler and the bracket, and the measuring ruler is used for making contact with the front edge and the rear edge of a guide vane. The guide vane angle checking device is reasonable in structural design, the guide vane inlet angle can be quickly and accurately checked, the labor intensity is reduced, and the labor efficiency is improved.

Description

Technical field [0001] The invention specifically relates to a device for checking the inlet angle of a guide vane of a gas turbine, a fan, a steam turbine, etc., and a method for checking the angle of the guide vane using the checking device. Background technique [0002] The inlet guide vanes of gas turbines, fans and steam turbines need to be angle checked before use to prevent the inconsistent angle of the inlet guide vanes from affecting the nature of the intake fluid, causing excessive vibration of the equipment, affecting the efficiency and life of the equipment. However, due to the large number of imported guide vanes, and most of the imported guide vanes have different twist angles, the inspection space is limited, the inspection of the inlet angle is difficult, the workload is large, and the accuracy is difficult to control. Summary of the invention [0003] In view of this, in order to overcome the defects of the prior art, the purpose of the present invention is to pro...
