摘要
安徽省凤凰颈排灌站是一座大型双向 X型流道泵站。文中简述了凤凰颈泵站机组运行中出现的故障 ,即机组振动问题 ;分析了故障产生的主要原因 ,是由出水流道水流脉动压强差引发了泵轴振摆 ,导致机组振动 ;本研究采用隔开振动源的措施消除了故障。通过运行实践证明 ,隔开振动源的方法简单、合理、可行 ,达到了使机组运行平稳的预期效果 ,并取得了显著的经济和社会效益。
This atricle analyzed the malfunction in the Fenghuangjing Pumping Station, whic h was caused by the fluctuation pressure intensity error in outlet. By spacing o ut the vibration source,we solved this problem. According to the operation, it i s proved that this method is casy and reasonable. This method gets the desired e ffect making the pumping axis working stable, resulting in district economical a nd social benefits.
