Study result of this paper reveals that the main source of noise in papermaking plant is from vacuum couch.
真空伏辊产生的噪声是造纸车间的主要噪声源。
The key point of reducing noise of paper machine is to reduce aerodynamic noise of vacuum couch.
降低真空伏辊空气动力性噪声是降低抄纸机噪声的关键 。
Couch: Device at the end of the wet end of a paper making machine where the wet paper is passed to the press section .
伏辊:造纸机上湿部末端的装 ，它把湿纸送往压榨部。
