Types and principles of high-pressure water mist fire extinguishing devices

The high-pressure water mist fire extinguishing device (open type) is mainly composed of high-pressure pump group, water tank, pump group control cabinet, pressure stabilizing pump, filter device, open type partition control valve, open type water mist nozzle and other components and water supply pipes, which can Automatically and manually activated and spray fine water mist for fire extinguishing or fire control.

Features of high pressure water mist fire extinguishing system

Efficient fire extinguishing - the cooling rate is 100 times faster than that of the general sprinkler system. The high-pressure water mist is also penetrating, which can solve the problems of total submersion and occlusion, and can also prevent the resurgence of fires.

Start-up method of high-pressure water mist fire extinguishing device

When a fire breaks out in the protected area, the fire detector detects the fire and sends a signal to the fire alarm controller. The fire alarm controller confirms the area where the fire occurs according to the address of the fire detector, and then sends a control signal to start the fire extinguishing system in linkage, and opens the corresponding area valve. After the area valve is opened, the pipeline pressure drops, and the stabilized pump automatically starts running for more than 10 seconds. Because the pressure still does not reach 8bar, the high-pressure main pump automatically starts, and the water in the system pipeline quickly reaches the working pressure, and is sprayed through the high-pressure water mist nozzle. out, producing fine water mist to extinguish the fire.

Working principle of PHP mechanical pump

The mechanical pump-in proportional mixing device is a flow balance proportional mixing device. Driven by the fire-fighting water flowing in the pipeline, the water turbine drives the foam liquid pump to extract the foam liquid in the atmospheric pressure tank and pump it into the main fire-fighting pipeline. Through the matching of structural parameters inside the water turbine and the foam liquid pump, the flow of water and the flow of foam liquid are balanced to achieve constant ratio mixing. The mechanical pump-in proportional mixing device is small in size, small in floor space, accurate in mixing ratio control, and does not require external power supply or diesel engine.
