  • Publication number: 20210046345
    Abstract: A fire-fighting system includes a pump, a nozzle for directing fluid flow from the pump to a target area, a discharge valve controlling fluid flow between the pump and the nozzle, a sensor coupled to the nozzle, and a controller communicatively coupled to the sensor. The sensor detects movement of the nozzle and generates a signal indicative of the detected movement. The controller communicatively coupled is configured to receive the signal from the sensor, and control at least one of the discharge valve, the pump, and the nozzle based on the detected movement of the nozzle.

  • Patent number: 10711440
    Abstract: An automatic fire hydrant water supplying system provides hydrant supply water to a fire truck having a water pump; a water pump master intake valve; a water-supply fire hose, a pressure sensor upstream of the master-intake-valve, and a water-pump control system. The automatic fire hydrant water supplying system has a remotely-controllable hydrant discharge valve connectable to the hydrant and to the fire-hose. A remotely-controllable air bleed valve is in fluid communication with the master-intake-valve and the fire-hose. The water-pump control system determines whether a pressurized volume in the fire hose upstream of the master-intake-valve input port is air or water based on a difference in density between air and water as sensed by the pressure sensor and if the pressurized volume is air causes the air to be vented to atmosphere through the air-bleed-valve before opening the master-intake-valve to provide hydrant supply water to the water pump.

  • Patent number: 8162619
    Abstract: A system for controlling the pressure output of an engine-driven centrifugal fire pump includes a discharge pressure sensor mounted in the discharge line of the pump. A governor varies the rpms of the engine in response to pressure changes detected by the discharge pressure sensor. If the pressure in the system is higher than the desired output pressure when the engine is running at its idle speed an electronically controlled hydraulic relief valve responsive to the discharge pressure sensor operates to relieve the excess pressure in over pressure situations. If the pressure in the system is lower than the desired output pressure when the relief valve is fully closed, the engine speed is increased.
