Research on Active Floating Raft of Pumps

随着减振需求的不断提高,世界各国针对泵类设备开展了较为深入的振动控制技术研究,浮筏隔振、主动隔振等振动控制措施得到了不同程度的应用。根据泵类设备振动控制需求,本文提出了一种泵集中布置、浮筏隔振与主动隔振相结合的主被动混合减振技术——主动浮筏隔振技术,以隔离泵宽频振动幵抑制特征线谱。通过开展固有频率分析、减振效果分析等对主动浮筏隔振技术可行性迚行了验证。分析结果表明,主动浮筏隔振减振效果良好。

With the increasing requirement of the control of the pump vibration,the vibration control technologies were deeply studied for various pumps worldwide.Vibration control measures such as floating raft and active vibration isolation have been applied in varying degrees.Based on the requirement of the control of the pump vibration,the technology combining the active and passive vibration reduction(the technology for the vibration isolation by active floating raft)is proposed,which is with the centralized arrangement of pumps and the combination of vibration isolation by floating raft and active vibration isolation.It can isolate the broadband vibration and inhibit the characteristic spectrum..The feasibility of active floating raft vibration isolation was verified by the analysis of natural frequency and vibration reduction effect.The results show that the active floating raft is with good performance in vibration reduction.
