WZ-FC/B intelligent fire pump inspection cabinet
With the rapid development of the city, various buildings are increasing day by day, various flammable materials are widely used, and people’s awareness of fire prevention is not strong. This greatly increases the possibility of fire. “Although every building is currently equipped with Fire extinguishing system, but experience and lessons have proved that the success of fire remediation mainly depends on whether the fire water supply equipment is in good condition. The fire pump is a vertical part of the fire extinguishing system. To be 100% effective, due to the long-term idle state and the humid environment of the pump room, it is easy to cause the fire pump shaft and impeller to corrode, rust and the electrical components cannot be used normally, and even in the event of a fire, the fire pump cannot work normally. It is impossible to put out the fire and endanger the safety of people’s lives and property.

Maintenance-free battery
According to the discharge characteristics of the maintenance-free lead-acid battery (refer to the instructions of each battery manufacturer), the capacity of the selected battery can be set to be 2 to 3 times the accident capacity. Calculation of battery pack impulse (instantaneous) current: The maximum impulse (instantaneous) current that the battery pack can provide is generally 3 times the rated capacity of the maintenance-free battery.
