Fire pump controller

Fire pump controller, as one of the key devices in fire extinguishing system, is used for automatically controlling and monitoring the operating state of fire water pump to ensure fire water pump can start quickly and operate stably when fire occurs. Professional detailed introduction to fire water pump controller:

1. Main functions

Automatic control

-Automatic start: When it is detected that the fire extinguishing system pressure declines (e.g. start of water sprinkler or hydrant caused by fire), the controller can start the fire water pump automatically to ensure timely water supply.

-Automatic stop: After the fire is distinguished or the normal system pressure is recovered, the controller will automatically control the fire water pump to stop working to prevent unnecessary operation and energy consumption.

Manual control

-Manual start: In emergencies, the operators can directly start the fire water pump with the manual button on the control panel.

-Manual stop: The controller is configured with a manual stop function to facilitate operation and maintenance in special conditions.

2. Key components

Control panel

-Display screen: Display in real time the operating state of the fire water pump, the system pressure, current and other parameters.

-Indicating lamp and alarm: Provide visual and auditory alarms to prompt system faults, pump start or stop, etc.

Electrical components

-Relay and contactor: Control motor start and stop of fire water pump to ensure stable power supply and safe operation.

-Power switcher: Switch into the standby power (e.g. diesel generator) in the case of a power supply fault to ensure normal operation of fire water pump.

Sensor and switch

-Pressure sensor: Monitor the system pressure and provide real-time data to the controller for decision-making.

-Flow switch: Detect water flow to ensure fire water pump will not rotate without water or with a low water yield, to avoid damage to the fire water pump.

3. Installation and commissioning

Installation

-Position selection: Fire water pump controller should be installed in a dry and ventilated control room to facilitate operation and monitoring.

-Wiring requirement: The controller should be connected to the fire water pump, power supply, sensor, and other components in accordance with the electrical specifications to ensure correct and firm wiring.

Commissioning

-Initial start: The initial start testing should be performed after installation to ensure the controller and the fire water pump work normally.

-Parameter setting: The start pressure, stop pressure, delay start and other parameters of the controller should be set according to the design requirements of the fire extinguishing system.

4. Maintenance and servicing

-Regular inspection: All functions of the controller should be inspected on a regular basis to ensure normal working of the display screen, indicating lamp and alarm.

-Troubleshooting: Existing faults should be investigated and repaired timely to ensure reliable operation of the controller and the fire water pump.

-Record retention: Operation and maintenance should be recorded properly during maintenance to facilitate future analysis and troubleshooting.

5. Application scenarios

Fire water pump controller is widely applied to fire extinguishing system of kinds of architectures and facilities, including but not limited to:

-High-rise buildings: office buildings, residential buildings, hotels, etc.

-Industrial facilities: factories, warehouses, oil refineries, etc.

-Commercial places: shopping centers, supermarkets, entertainment places, etc.

-Public facilities: schools, hospitals, stations, airports, etc.

Conclusion

Fire water pump controller is a core device for ensuring reliable start and stable operation of the fire water pump. Through automatic control and real-time monitoring, fire water pump controller can respond quickly in the case of fire and provide continuous fire water guarantees. Its key functions and reliability have played a key role in modern fire extinguishing system and serves as one important constituent of fire safety.
