The vacuum generator is a venturi principle, which uses the change of flow speed, pressure and state of fluid in a variable-section pipeline to realize the expected energy conversion. After the mixed fluid in the Venturi tube is subjected to reducing in the tube, the Mach number changes suddenly, namely the speed changes greatly. According to the working principle, the airflow gradually accelerates to local sonic speed from the inlet to the throat part of the nozzle, and expands to supersonic speed when being sprayed out of the nozzle. After being discharged together with the sucked gas through the expanding pipe, the speed is reduced to subsonic speed.
When the flush button is pressed, compressed air flows through the vacuum generator at high speed, and the high speed air flow generates a jerky noise, which is measured to be 65 db in 2m around the vacuum generator, thereby causing noise pollution.

The grip ring 45 is then gripped and moved upward so that the cover plate 43 and the second soundproof layer 44 can be moved upward and detached from the housing 41. Then, the vacuum generator is placed in the housing 41, the air inlet pipe of the vacuum generator is connected to the vacuum generator in the housing 41 through the first and second air inlet holes 411 and 421, the vacuum pipe of the vacuum generator is connected to the vacuum generator in the housing 41 through the first and second vacuum holes 412 and 422, and the exhaust pipe of the vacuum generator is connected to the housing 41 through the first and second exhaust holes 413 and 423.

And the user can push the invention patent to the required position, and the use is convenient. When the height of the operator is high and the height of the shell 41 needs to be increased, the switch of the electric cylinder 31 is turned on at the moment, so that the push rod 32 moves upwards, the rotating rod 35 rotates around the connecting block 34 clockwise, the roller 36 pushes the support plate 2 upwards, the support plate 2 can be pushed to the high position until the requirement of the operator is met, and the use is convenient. The use process of the noise reduction system of the train vacuum generator is described.
