How Does A High-pressure Misting System Work?

High-pressure misting systems produce tiny water droplets in the form of fog. This raises humidity and cools without getting anything wet. The small water droplets work together to eliminate tiny particles of dirt, dust, and odor-causing bacteria by attracting and absorbing the particles from the air. Here let’s take a water mist fire extinguishing system as an example: High pressure pumps force water through the stainless-steel water mist nozzles, discharging the water in the form of millions of tiny droplets. An activated system will create a blanket of water mist droplets which maximize heat absorption from the fire, and subsequently displacing oxygen upon evaporation and expansion of the water mist as it converts to steam. Water mist systems are differentiated from sprinkler systems by mist’s unique ability to present a much greater water surface area (enabling rapid heat absorption), combined with the mist’s ability to remain suspended in the air for a much longer duration – thereby creating more exposure time for the heat absorption to take effect. This enables water mist systems to cool and suppress fire using considerably less water than sprinkler systems.

High-Pressure Water Mist for Firefighting

The volume of finely atomized water dispersed in close proximity to the flame creates a high quantity of water vapor, which displaces the surrounding air and thus its oxygen, choking the flame. The transition from the liquid to the gaseous state absorbs a high amount of energy.
Our AHP high-pressure pumps are suitable for high-pressure water mist fire-fighting systems. Among them, AHP63 and AHP80 have obtained China Classification Society certification of type approval. The water quality of the AHP series pumps is tap water, and the pressure can be as high as 160bar. These pumps can be used with our pilot electric valves, Safety valve, high-pressure hose connector, high-pressure hose, etc.

Features And Benefits

1. Lightweight and compact (coupling can be used to directly install on the motor or internal combustion engine)

2. Very small pressure pulses generated in the pipeline

3. No preventive maintenance (no fixed maintenance such as changing lubricating oil or wearing parts)

4. Long maintenance period

5. All parts of the pump are made of corrosion-resistant materials, and the surface is easy to clean

6. Less wearing parts

3 piston Pump Vs. 9 piston Pump

The high pressure piston pump is the most important component of the high pressure water mist fire extinguishing system. There are two types of high pressure pumps currently used in the market, one is a nine-piston pump and the other is a 3 piston pump.

Comparison of these two types of high pressure pumps:

9Compare items Vertical 9 piston pump Horizontal 3 piston pump
Lubrication form Water self-lubricating Oil lubrication of connecting rod
Cooling method The water is self-cooled, and the heat is discharged with the high pressure water through the nozzle The water tank is cooled by water, and the oil tank is not cooled, which will easily cause damage to the seal and seal failure
Pulse performance Small pulse, constant pressure Large pulse, extremely unstable pressure
Noise level 85 decibels at a distance of one meter More than 120 decibels at a distance of one meter
Basic requirements The vibration is small, the dynamic load is about 1.2 times of the static load The vibration is large, the dynamic load is more than 3 times the static load
Impact on pipe network and equipment No harm Great impact on the pipe network and great harm to the pressure sensor
Maintenance cycle Maintenance-free Need to regularly observe whether the lubricating oil leaks
Service life Around 8000 hours 2000-4000 hours
Shelf life All materials are wear-resistant and corrosion-resistant materials, which have been in a water environment for a long time The connecting rod of the pump is lubricated with oil, and it is easy to rust if it is not used for a long time in a water environment; if the pump head is made of copper alloy, it is easy to rust and the sealing performance becomes poor
Cost Slightly higher cheap
Application comparison of high pressure water mist fire extinguishing system The pressure is stable, and the number of high-pressure pumps can be started exactly according to actual needs; long life; maintenance-free; low noise The pressure is unstable, and the number of pumps cannot be started exactly according to the actual needs. All pumps in the pump group must be started, which can easily cause overpressure in the pipe network; it cannot be stored for a long time in a water environment and is easy to rust; check the lubricating oil regularly and regularly Maintenance; high noise; high vibration
In summary, the choice of the high pressure pump of the water mist system is the key to the use, maintenance and long-term backup of the water mist system. The performance of the 9 piston pump in the water mist system is obvious
