消防风机、消防水泵二次控制回路设计需要注意的几点问题

Some Problems Needing Attention in the Design of the Second Control Circuit of the Fire Engine and the Water Pump

分别从排烟风机的应急控制盘起停按钮设计不当、变频风机紧急停止控制回路设计不合理、消防泵控制回路消火栓箱内起动按钮线路过长电压降过大起泵继电器不动作、两用一备消防泵、喷淋泵两台水泵同时起动造成起动电流过大造成起动困难的缺陷。希望凭借多年对消防风机、消防水泵的设计制作经验,给予相关技术人员提供一定价值的参考。

in this article, the author from their years of work experience of respectively from the exhaust fan and the emergency control stop button poorly designed, frequency conversion fan emergency stop control circuit design is not reasonable, fire pump control loop fire hydrant box line button to start the long voltage drop too large pump relay action, a dual-use equipment, fire pumps, sprinkler pump two pumps and start causing starting current is too large starting defect. The author hopes that by virtue of their many years of design of fan for fire, fire pump production experience, gives related technical personnel to provide some valuable reference.
