Test lead cluster sealing device for test

Abstract

The invention belongs to the technical field of engine tests, and particularly relates to a test lead cluster sealing device for a test. The sealing device comprises a test lead seat (1), a sealing support plate (2) and a compression nut (4), the test lead seat (1) is fixed at an opening of the casing and is provided with a first through hole which is communicated with the opening of the casing and is used for a test lead (5) to pass through, the sealing support plate (2) can extend into and be fixed in the first through hole, the sealing support plate (2) is provided with a second through hole which is used for the test lead (5) to pass through, and the compression nut (4) is fixed on the sealing support plate (2). A threading groove (21) is formed in the side edge of the sealing supporting plate (2), so that after the end of a test lead (5) penetrates through the first through hole, the middle of the test lead (5) can be clamped into the second through hole from the threading groove (21), and the second through hole serves as a bunching hole to be used for pressing the test lead. The bunching hole of the sealing supporting plate is designed, it is guaranteed that the test lead can be tightened, and the sealing performance is guaranteed.

Description

Technical field [0001] The present application belongs to the engine test technology, and specifically, a test test lead bundle sealing device is used. Background technique [0002] A large number of whole machine, component test, and testing are an indispensable part of the engine development work. With the development of aviation propulsion technology, calculation technology and electronic computer application technology, people have established a more complex design and analysis method to accelerate the development process of the aviation propulsion system, and these engineering design and analysis methods need more, more precise and detailed Test test data to verify and confirm, therefore, the engine test has also put forward more and more requirements, test items, content, parameter type, but with the development of engine, the engine is high temperature, high pressure, Under high speed, large flow, etc., make parameters measurement more and more difficult. [0003] In order...
