主泵区域火灾探测的创新投运

Innovation and Operation of the Fire Detection in the Primary Pump House

以往主泵区域火灾探测设备有两种——红外火焰探测器和吸气式感烟探测器。在近几年的维护过程中,红外火焰探测器故障率高。因此,取消了红外火焰探测器,改为两台吸气式感烟探测器双独立运行模式,避免以往高温高辐射环境对主设备的影响,增加了火灾设备的使用寿命,降低了维护成本。实施至今近两年时间,1、2号机组主泵间火灾探测运行稳定。

There are two kinds of the fire detection equipment in the primary pump house.One is infrared flame detector,the other one is aspiration smoke detection.But the failure rate of infrared flame detectors is high in recent years.So we dismantling the infrared flame detectors and replace them by aspiration smoke detection.This avoids the influence of high temperature and high radiation on equipments,increases the service life of fire equipment and reduces the maintenance cost.
