In petrochemical companies, the handling of flammable and explosive chemicals is extremely complex, making effective fire protection measures key to disaster prevention. Foam firefighting equipment plays a vital role in this process. It quickly covers the source of the fire and blocks the air, so as to effectively control and extinguish the fire.
The balanced proportional mixing device is at the heart of it all. This device precisely controls the mixing ratio of foam and water to ensure that the foam works best during firefighting. Whether in the face of a small spill or a large fire, this highly efficient proportional mixing technology provides the optimal solution for extinguishing the fire.
When a fire breaks out, the fire fighting system is immediately mobilized. The fire pump is activated automatically or manually and the balanced proportional mixer starts working. In this process, a pressurized stream of water passes through the mixer, triggering a series of precision operations.
The foam dope inlet valve and the turbine control valve are opened by remote control from the fire control center or by command of the automated control cabinet (in the case of electric motor or diesel engine drive, the turbine control valve is not involved). At this time, the foam pump is also activated synchronously, and the foam liquid stored in the atmospheric foam tank is introduced into the proportional mixer.
After the automatic adjustment of the balance valve, the appropriate amount of foam liquid and pressure water are mixed in the proportional mixer according to the established ratio to form a foam mixture. This mixture is transported to the foam generating equipment for firefighting through pipelines, such as foam guns, foam cannons, foam generators, etc., and finally produces air foam for extinguishing Class A, B and C liquid fires.
All in all, the balanced proportional mixing unit provides strong support for fire extinguishing with its high degree of integration, precise control and wide adaptability. It not only represents the frontier of fire-fighting equipment technology, but also an important guarantee to protect the safety of life and property.
