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.

Claims

1. An operation display apparatus for a fire pump, said operation display apparatus comprising:

an operation unit having at least one key for controlling an operation of the fire pump and for generating a sound corresponding to the control thereof;

wherein operation of the fire pump corresponding to the key is carried out only when the key is operated continuously for a predetermined period of time; and

a display unit for displaying operation information on the fire pump corresponding to the operation of the fire pump controlled by said operation unit.

2. The operation display apparatus according to claim 1, wherein the key is for stopping a fire pump driving engine of the fire pump.

3. An operation display apparatus for a fire pump, said operation display apparatus comprising:

an operation unit for controlling an operation of the firepump and for generating a sound corresponding to the control thereof;

wherein said operation unit has a key for setting as a reference value a pressure at the time a water pressure detection sensor for detecting pressure of water supplied to the fire pump is operated; and

a display unit for displaying operation information on the fire pump corresponding to the operation of the fire pump controlled by said operation unit.
