Analysis of Vibration Characteristics of Marine Centrifugal Pump Excited by Multiple Vibration Sources

  • 摘要: 为了确定流体激励和轴系激励对离心泵振动的主要影响,通过对离心泵进行非定常流场计算,分析流体激励和轴系激励诱导离心泵振动特性。选择采用轴系不对中作为激励源,结果表明:轴系不对中时,离心泵在1APF(电机转动频率)处振动响应增强,并出现明显的2APF响应,1BPF(1倍叶片通过频率)处振级和中频段振级几乎无变化;当流体激励并伴有轴系不对中时,离心泵在1APF处和1BPF处出现明显的振动响应,1BPF处的振级与仅轴系激励时相差较大。
