真空泵除了真空泵本身的运行噪音，真空泵排气也会产生较大的排气噪音，如果真空系统频繁破大气，排气噪音会对周边产生噪音影响，可以在真空泵排气口

增加消音器降低排气噪音，在消音器口再进行配管接出对排气噪音的消除就更有效。

In addition to the operational noise of the vacuum pump itself, the exhaust of the vacuum pump also generates significant exhaust noise. If the vacuum system frequently leaks to the atmosphere, the exhaust noise can have a noise impact on the surrounding area. It is possible to install a silencer at the exhaust port of the vacuum pump Adding a muffler to reduce exhaust noise, and then connecting a pipe at the muffler outlet to further eliminate exhaust noise, will be more effective.
