高层建筑的防火立足于自救且以室内消防给水系统为主,消防水泵为系统提供动力是消防给水管网中的关键设备,其可靠性对高层建筑的防火有着重要作用。低压变频自动巡检技术由微机控制器(PLC))按照设定的巡检周期通过变频器启动巡检程序低频驱动消防泵转动,解决了水泵由于长时间不用泵轴抱死而无法及时启动的问题,同时可以对电气主回路断电、过电流、短路、互投等功能进行检测,有效了保证了消防水泵的可靠性,值得在消防系统中进行推广。
The fire prevention of high-rise buildings is based on self-help and is mainly based on the indoor fire water supply system. The fire pump provides the power for the system is the key equipment in the fire water supply network. Its reliability plays an important role in the fire prevention of high-rise buildings. Low-voltage inverter automatic inspection technology by the computer controller (PLC)) in accordance with the set inspection cycle through the inverter to start the inspection process Low-frequency drive fire pump rotation, to solve the pump because of a long time without pump shaft lock and can not start in time At the same time, it can test the functions of power main circuit, power supply, short circuit and mutual input, which effectively ensures the reliability of the fire pump and is worth promoting in the fire protection system.
