Fire pumps are widely used in our lives, such as in water treatment, fire safety and other departments. At the same time, it has the characteristics of full sealing, no leakage and corrosion resistance, and is widely used in life and production. In transportation and The storage aspect also shows its excellent characteristics, and it has become an indispensable device in many places now.
In people’s common sense, the fire pump is mainly used for water delivery in the fire protection system. As an indispensable tool for the fire protection system, the fire pump also has the characteristics of simple structure and stable performance, and its high speed, small size and high efficiency are also a major advantage. , it is precisely because of these advantages of high performance and low energy consumption that the safety and efficiency of the fire pump are far ahead of the pipeline tools of the same purpose.

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.

An FDC is an external connection point that allows the fire department to supplement the water supply to the fire protection system using their hoses and equipment if needed.
