Shandong Dongyue PHYML Vertical foam Tank Price Introduction foam Fire Extinguishing Equipment Manufacturer

Description :

　　The pressure type foam proportioning device is used to store foam extinguishing agent and replace foam extinguishing agent through the pressure type foam proportioner using the water supply of the pump set, and mix with the water supply in a certain proportion to form foam mixture.

　　The pressure type foam proportional mixing device is a common foam extinguishing equipment at present. The pressure type foam proportioning device is easy to install, use and maintain, with excellent built-in corrosion resistance, relatively economical cost, stable and reliable performance, and is especially suitable for medium and small flow foam fire extinguishing systems. Mainly applicable to places where flammable or combustible liquids are produced, stored, transported, and used; Fire hazard areas such as petrochemical enterprises, oil depots, loading and unloading docks, ship docks, oil extraction platforms, aircraft hangars, and automobile garages.

　　Ground type fixed roof oil tank and internal floating roof oil tank shall be equipped with low expansion foam fire extinguishing system, etc. When the floating roof oil tank is equipped with foam mixture through central hose, medium expansion foam fire extinguishing system can be set. The domestic medium expansion foam solution is a fluoroprotein foam solution. The foam expansion ratio is between 21 and 200, which can be used in local application and mobile medium expansion foam fire extinguishing systems. The medium expansion foam solution below 50 times is suitable for liquid extinguishing of aboveground oil tanks, and the solution above 50 times is suitable for flowing fire extinguishing.

　　Medium expansion foam refers to foam expansion ratio between 21 and 200. Medium expansion foam fire extinguishing system is generally used to control or extinguish flammable, combustible liquid, solid surface fire and solid deep smoldering fire. Its stability is low, and the foam extinguishing system is poor. To some extent, it will be affected by the wind, and its anti reburning ability is low. Therefore, the intensity of supply needs to be increased during use. The medium expansion foam extinguishing system can put out the fire in the vertical steel oil tank.
