Embodiment Construction

[0044] This embodiment is a guide vane water flow measuring fixture, including a fixture bottom plate 12, a support, a blade lower edge plate gasket 20, a blade upper edge plate gasket 21, a control valve, a water inlet pipeline and a water outlet pipeline.

[0045] The supports include a first support 11 and a second support 14 . The first support 11 and the second support 14 are symmetrically fixed on the upper surface of the jig bottom plate 12 . Both ends of the second water inlet pipeline 16 are respectively connected to the third water inlet hole 42 and the fourth water inlet hole 43 of the holder on the second holder 14 through the adapter 19 . Both ends of the second water inlet pipeline 16 are respectively connected to the fourth control valve 15 and the third control valve 18 through right-angle elbows 23 . There is a second water inlet 17 on the pipeline between the fourth control valve 15 and the third control valve 18 . The blade lower edge plate gasket 20 is fi...

Abstract

The invention discloses a guide blade water flow measuring clamp and a guide blade water flow measuring method. Improvements on aspects of a sealing pad, a clamp passage structure and a water inlet waterway control are made. The sealing pad is changed into a mode that a blade is integrally contained and sealed and cavity passage docking is reserved, so that effective sealing is realized and the objective of multi-passage measuring is realized; four corresponding water incoming passages are designed for a clamp corresponding to the blade according to the position of a hole of the blade to be suitable for water incoming systems of four cavities of the blade. By the guide blade water flow measuring clamp and the guide blade water flow measuring method, the four cavities of the blade can be communicated with the four water incoming passages of a measuring system simultaneously only by clamping and mounting the blade for one time, and when measuring any cavity of the blade, water flow value of the cavity can be acquired only by opening a control valve. The guide blade water flow measuring method is simple and convenient to operate and stable in data, and the guide blade water flow measuring clamp is timesaving, laborsaving and good in sealability.

Description

technical field [0001] The invention relates to the field of manufacturing aeroengine blades, in particular to a blade water flow measuring method and a measuring fixture. Background technique [0002] In order to ensure the air film cooling effect of the aero-engine guide vanes during use, the design checks whether the vanes meet the design requirements by measuring the water flow values ​​in each inner cavity of the vanes. At present, the principle of water flow measurement for all blades is basically the same, and special water flow test equipment and special measuring fixtures are required. The flow test equipment provides a water source with a certain pressure and can detect the flow of water out of the system. The measuring fixture is used to fix the blades and The water source of the flow test equipment is connected with the pipeline, and the water source is introduced into the designated cavity of the blade, so that the flow value of the system outlet water when the ...
