What is the role of a fire pump controller?

The conventional electric pump is the main pump, the diesel engine pump is the backup pump, and the voltage stabilizer pump plays a role in the stabilization of the whole system. When the electric pump fails or the mains is cut off, the control cabinet will receive the pressure gauge from the electric contact. When the signal comes, the diesel engine pump will be started within 5 seconds, and the rated working condition will be reached within 20 seconds to ensure the normal operation of the fire extinguishing work.

Regular maintenance is crucial to keep fire pumps in optimal condition. It involves inspecting, lubricating, and replacing components as needed. Maintenance helps prevent malfunctions, ensures reliability, and extends the life of the pump.

1. Water filling treatment Before selecting the power-on power, make sure that the fire pump should be filled with water when it is turned off, and the suction should be increased to make the pressure difference larger and quickly clean up some acid-base reagents and other pollutants. Make sure to fill the water well.

2. Selection of electrified power The horsepower of the fire pump will be selected according to the size of the pump. Before electrifying the pump, carefully check the electrical power. Once the power is not grasped accurately, it is easy to cause insufficient suction. Therefore, in order to make it have sufficient suction, the power should be selected reasonably. If there is no electricity, the fire pump cannot be started, let alone used. But does it mean that the pump can be used as long as there is electricity? Not necessarily, the pump can only be used if the electrified power is reasonable and the voltage is within the normal range.

The application of fire pumps is not only in fire protection systems, but a variety of fire pumps are gradually showing their superior strength in industrial production and urban construction. This includes the implementation and expansion of high-end technologies for industrial and urban water supply and drainage, and high-rise water supply under pressure.

1. Visually inspect the fire pump for any signs of damage or leaks.

2. Check the oil level and add oil as necessary.

3. Check the suction and discharge valves for proper operation.

4. Check the inlet and discharge pressure gauges for accuracy.

5. Check for any foreign objects in the suction and discharge piping.

6. Inspect the fire pump for any signs of corrosion or wear.

7. Lubricate all bearings and drive components.

8. Check the electrical connections for any signs of corrosion or wear.

9. Clean the exterior of the fire pump and its components with a damp cloth.

10. Test the fire pump to ensure its proper operation.
