Description

Technical Field

[0002] High-pressure water mist systems generally include bottle-type high-pressure water mist systems and pump-type high-pressure water mist systems. Bottle-type high-pressure water mist systems have the characteristics of small footprint and fast response time. However, due to the small amount of water stored in them, they are generally used in environments with small fire extinguishing areas. For fire extinguishing protection in a large area, pump-type high-pressure water mist systems are generally used. They have a large water storage capacity and are connected to municipal water pipes. They can respond to fire signals based on temperature detectors. After the control system and smoke detectors confirm the alarm, they start the pressure-stabilizing pump and the working pump in turn to open the fire extinguishing area. The disaster zone control valve box allows fine water mist to be sprayed out from the nozzle to extinguish the fire. Therefore, the pump-type high-pressure fine water mist system is also generally used in large buildings. However, since the various equipment in the pump-type high-pressure fine water mist system is scattered in different areas of the building, the person in charge of fire protection cannot conduct centralized and real-time online monitoring of each component equipment, and cannot immediately obtain the operating status of each equipment in the high-pressure fine water mist system. It is also impossible to automatically allocate the pump group, and there are often abnormal system pressure or flow conditions, resulting in additional energy loss of the pump group or the high-pressure fine water mist provided cannot cover the area.
