两台汽泵同时振动大跳泵的原因探讨

Two Steam Pump Vibration Striptease at the Same Time Explore the Reasons for the Pump

针对两台汽动给水泵同时振动大跳泵的现象,分析跳泵原因,并介绍给水泵最小流量阀的工作机理及运行中对其手动截止阀进行操作时应注意事项。提出对电厂汽水系统阀门操作时要注意其前后压差的变化,避免高压差阀门内发生汽蚀的破坏性。

Two steam-driven pumps to pump striptease at the same time the phenomenon of vibration analysis jump pump reasons,and introduced the minimum flow valve to the pump mechanismand the work of its manual operation of the valve to operate attention should be paid to issues.Proposed power plant steam and water system valves must pay attention to its operation before and after the changes in pressure and avoid high-pressure differential within the cavitation valve destructive.
