【摘要】：消防水泵流量和扬程设计一般均按最不利点最大流量和扬程进行选型。大部分火灾在初期可能就被灭火系统扑灭,实际火灾初期时只需要很小的流量,必然会存在小流量工况点。消防泵在小流量工况点运行时可能造成部分管道超压振动,合理的预测和消除消防水泵管道振动问题及采取有效措施,可以保护消防系统有效地运行。该问题处理适用于类似问题的应用借鉴。
[Abstract]:The design of flow and head of fire water pump is usually based on the maximum flow and head of the most disadvantageous point. Most of the fires may be extinguished by the fire extinguishing system in the initial stage, but only a very small flow rate is needed in the early stage of the fire. It is inevitable that there will be a small flow rate operating point. The fire pump may cause part of the pipeline overpressure vibration when operating at the small flow condition. The reasonable prediction and elimination of the fire pump pipeline vibration problems and effective measures are taken. It can protect the fire fighting system from running effectively. The problem handling is applicable to the application of similar problems.
