摘要
对于液体 (润滑油、水 )泵的管流噪声 ,针对一齿轮泵和叶片泵的出口流动噪声设计了扩张管 ,并进行了试验测试。结果表明 ,对于泵的额定工况 ,所采用的方法可达到管壁振动加速度降低 6-1 0分贝。
In oredr to reduce the noise from the liquid flow in the outlet pipe of pupmp,expanded-mufflers are designed for two kinds of pumps with gears and blades,and experiments are conducted.The reduction of noise lever measured in the acceleration on the pipe wall is obtained about 6 to 10 decibel.
