The HPWM is composed of high pressure main pump, standby pump, electromagnetic valve, filter, pump control cabinet, water tank assembly, water supply network, regional valve box components, high pressure water mist spray head (including open type and closed type), fire alarm control system and water replenishment device.

2. Application classifications of high pressure water mist

(1) Fully submerged water mist system

A water mist fire extinguishing system that can evenly spray water mist into the entire protection area to protect all the protection objects inside.

 (2) Local application water mist system

Spraying water mist directly to the protection object, used to protect a specific protection object indoor and outdoor or local space.

 (3) Regional application water mist system

Water mist system to protect a predetermined area in the protection zone.

 

3. Advantages

(1) No pollution or damage to the environment, protected objects, an ideal environmentally friendly product.

(2) Good electrical insulation performance, safe and reliable in fighting fires of live equipment

(3) Less water used for fire extinguishing , and the less residue of water stain.

(4) The water mist spray can greatly reduce the smoke content and toxicity in the fire, which is conducive to safe evacuation.

(5) Good fire extinguishing performance and wide applications.

(6) Water – the fire extinguishing agent, wide range of sources and low cost.

 

4. Suitable for fighting the following fires:

(1) Flammable solid fires in stacks, archival databases, cultural relic stores, etc.

(2) Flammable liquid fire in hydraulic station, oil immersed power transformer room, lubricating oil warehouse, turbine oil warehouse, diesel engine room, fuel boiler room, fuel direct combustion engine room, oil switch cabinet room and other places.

(3) Flammable gas injection fires in gas turbine rooms and directly fired gas engine rooms.

(4) Electrical equipment fire in the distribution room, the computer room, the data processing machine room, the communication machine room, the central control room, the large cable room, the cable tunnel (corridor), the cable shaft and so on.

(5) Fire tests in other places such as engine test rooms and traffic tunnels suitable for water mist fire suppression.

5. High pressure water mist fire extinguishing system can be started by three modes, automatically start, manually (remote or local) start and mechanically emergency start.

Automation: To change the control mode on the fire extinguisher into Auto, then the system is on automatic state.

When a fire occurs 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 of the fire according to the address of the fire detector, and then sends out the control signal of the linkage starting fire extinguishing system, and opens the corresponding area valve. After the valve is opened, the pressure of the pipe is reduced and the pressure pump is automatically started for more than 10 seconds. Because the pressure is still less than 16bar, the high pressure main pump starts automatically, the water in the system pipe can reach the working pressure quickly.

 Manually control: To change the fire control mode into Manual Control, then the system is in manual control state.

Remote start: when people find the fire without detecting, people can start the respective buttons of electric valves or solenoid valves through the remote fire control center, then pumps can be started automatically to provide water for extinguishing.

Start in place: when people find fire, they can open the regional value boxes, and press the control button to extinguish fire.

Mechanical emergency start: In the case of fire alarm system failure, the handle on the zone valve can be manually operated to open the zone Valve to extinguish the fire.

System recovery:

After extinguishing the fire, stop the main pump by pressing the emergency stop button on the control panel of the pump group, and then close the area valve in the area valve box.

Drain the water in the main pipeline after stopping the pump. Press the reset button on the panel of the pump control cabinet to make the system in the state of preparation. The system is debugged and checked according to the debugging program of the system, so that the components of the system are in the working state.
