Abstract
In a fire pump adapted to force out the water, which is pumped from a water source, from a nozzle provided at a front end portion of a delivery hose, a nozzle control unit 8 adapted to control the fire pump remotely is provided in the vicinity of the nozzle. The nozzle control unit 8 is connected to a body of the fire pump 1 by power source lines 33. On the nozzle control unit 8, a control instruction unit for instructing an operating mode of the pump 1, and a numerical value display unit for displaying the operation condition of the fire pump are provided. The transmitting and receiving of an operation control signal and a condition display signal are done between the pump 1 and nozzle control unit 8 by power line communication via the power source lines 33, whereby the operation condition of the pump 1 is feedback displayed in real time in response to a control operation of a nozzle operator.
