摘　　要：泵站双向流道型式在发挥其优点的同时也带来了许多缺点,这些缺点使此类泵站的故障特点区别于其他装置形式的立式轴流泵站。案例分析将双向流道常见的故障类型分为水力故障、机械故障和电气故障,并对其中的典型故障发生的原因进行了详细说明,针对性地提出了相应的改进措施。The two-way passage type of pumping station has brought many shortcomings while playing its advantages.These shortcomings make the fault characteristics of such pumping stations different from those of other vertical axial flow pumping stations.The common fault types of two-way passage were divided into hydraulic fault,mechanical fault and electrical fault in case analysis,and the causes of typical faults were described in detail,and the corresponding improvement measures were put forward.
