Abstract

The invention relates to a noise reduction system of a vacuum generator. The system comprises a casing, wherein the inner part of the casing is hollow and an opening is formed for mounting the vacuumgenerator of the train; a cover plate is mounted at the opening of the casing for closing the inner part of the casing; and a snap joint device is mounted on the casing or the cover plate for fixing the cover plate to the casing. The noise reduction system of the vacuum generator of the train can reduce noses of the vacuum generator effectively, and is low in cost and suitable for being popularized and applied. The system is convenient to move, and can be adjusted to a needed height according to demands of an operator, and is convenient to use and simple to operate. The invention also relatesto the train.

Description

technical field [0001] The invention relates to the technical field of vacuum generator noise reduction, in particular to a vacuum generator noise reduction system and a train. Background technique [0002] At present, the vacuum generator used on the motor car will generate a lot of noise when it is working, which will cause noise pollution on the motor car. Although the vacuum generator will be equipped with a noise reduction device, its cost is high and the noise reduction effect is not good. Ideal, but can not meet the noise requirements on the train. [0003] Therefore, it is necessary to provide a new technical solution to overcome the above defects. Contents of the invention [0004] Compared with the prior art, the present invention aims to provide a vacuum generator noise reduction system to solve at least one of the above technical problems. [0005] The technical solution of the present invention to solve the above technical problems is as follows: a vacuum ge...
