Embodiment

[0032] The pipeline 23 and the pipeline 25 connected to the two ends of the high-temperature pipeline vibration isolator 24 are respectively fixed on the engine air inlet 22 and the frame web 26 of the engine room, and the combined welding angle of the three vibration isolation mechanisms is 150°40 '. When the engine is working, the vibration force generated is transmitted to the high-temperature pipeline vibration isolator 24 through the conduit 23. Under its vibration isolation effect, the vibration force is eliminated, and the transmission of the vibration force to the pipeline 25 is cut off, so as to avoid the pipeline from being damaged due to damage due to vibration.

Abstract

The invention belongs to the technical field of aviation, and relates to a high-temperature pipeline vibration isolator on a plane for cutting off the transmission of vibration force of airplane equipment in a high-temperature bleed air pipeline. The high-temperature pipeline vibration isolator adopts a vibration isolation combinational design, and consists of three vibration isolation mechanisms. The high-temperature pipeline vibration isolator has a large angular displacement and high vibration isolation performance, endures high temperature corrosion, is not influenced by temperature changes, has high sealability, cannot age or creep, has a long service life, and has small characteristic changes during mass production.

Description

technical field [0001] The invention belongs to the field of aviation technology, and relates to a high-temperature pipeline vibration isolator on an aircraft, which is used for isolating the transmission of vibration force of aircraft equipment in a high-temperature bleed air pipeline. Background technique [0002] In the aircraft bleed air pipeline, in order to eliminate the thermal deformation of the pipeline or isolate the vibration force, the measures of installing bellows compensator and rubber vibration isolator are generally used to solve the problem, but its own structural characteristics determine that it has limitations in use. , The disadvantages of the bellows compensator are: ① There are working temperature and pressure limitations. The corrugated compensator has a thin wall and low structural strength, and the temperature and pressure of the working medium passing through it should not be too high; ②The compensation capacity is small. Its compensation ability...
