一种低振动低噪声新型舰用离心通风机

针对现役舰用离心通风机振动大噪声大的问题，本文提出了一种新型离心通风机结构，设计实现了新型通风机的叶片、蜗壳和电机等通风机关键部件，经过性能测试和近140余台的实船应用表明该型离心通风机比普通离心通风机振动低2个数量级、噪声平均地6分贝、体积平均减小30%、重量平均减轻30%、功耗平均降低20%，可显著降低离心通风机的振动、噪声并提高舰船通风效果。

A New Type Low Vivration and Low Noise Centrifugal Fan for Warship

To reduce the noise and vibration of centrifugal fans,a new type fan was proposed in this paper,which includes new structure and impeller.Performance tests for the fan show that its average noises lower 6dB,vibrations lower 100 times,weights less 30%,volumes less 30%,power consumptions less 20% than the fans were used in ships.If new type fans are used in ships,the vibration and noise will be reduced and the ventilation effects will be improved significantly.
