洛阳第七二五研究所拍打试验机室噪声高达113.5dB(A),室外达96dB(A),噪声污染极其严重。采取综合治理后,试验机室内操作位置的噪声降为92dB(A),室外降为67dB(A),操作人员十分满意,科研大楼和周围宿舍有关人员不再受噪声危害了。一、原始状况为进行船用橡胶材料寿命及强度等试验而设计的拍打试验机,是由进气管、电动机(55kW)、离心风机、试验坑等组成的试验装置,试件装在离心风机排气处特制的喇叭口上,对试件边吹气边喷水,以模拟海浪
Luoyang seventh Twenty-five Institute beating test room noise up to 113.5dB (A), outdoor 96dB (A), noise pollution is extremely serious. After comprehensive treatment, the noise in the operating position of the testing machine dropped to 92dB (A) and the outdoor area dropped to 67dB (A). The operators were very satisfied with the noise in the research building and the dormitory nearby. First, the original situation for the marine rubber material life and strength test designed flapping test machine, is by the intake pipe, motor (55kW), centrifugal fan, test pit and other components of the test device, the specimen installed centrifugal fan exhaust Department of the special bell mouth, the side of the specimen while blowing water to simulate the waves
