Conventional foam extinguishing equipment Horizontal foam tank Fixed foam extinguishing device

Description :

　　Foam is a group of bubbles with small volume and surrounded by liquid on the surface, which only fights fires caused by flammable liquid and gas. The foam used in China includes chemical foam and air mechanical foam (air foam for short).

　　The main principle of foam fire extinguishing is that foam is lighter than flammable and combustible liquids, and it covers the liquid surface on fire to prevent liquid vapor from entering the combustion area, prevent air from contacting the burning surface, prevent heat from conduction to the liquid surface, and absorb certain heat, thus stopping combustion.

　　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.

　　The PHYM series pressure type proportional mixing device produced by Shandong Dongyue Crane Fire Fighting Equipment Manufacturing Co., Ltd. is referred to as horizontal foam tank. It is produced in strict accordance with national standards, with advanced technology, mature technology, complete models and stable performance, and is suitable for all kinds of foam liquid with a mixing ratio of 3% or 6%; The mixed liquid flow is 24-80L/S, and the volume of foam tank is 3000L-10000L. Generally, the capacity of horizontal foam tank is larger than that of vertical foam tank.

　　The volume of a single tank of the pressure proportional foam proportioning device should not be greater than 10m3. The skin bag of the bladder pressure foam proportioning device should meet the requirements for strength, corrosion resistance and storage time when storing and using foam liquid.

　　The foam liquid tank should be made of corrosion-resistant materials; When using steel tanks, their inner walls should be treated with anti-corrosion measures. The inner wall or anti-corrosion coating in direct contact with foam liquid shall not have adverse effects on the performance of foam liquid.

　　The storage tank of pressure type foam proportioning device of storage tank shall be equipped with safety valve, slag discharge hole, feeding hole, manhole and sampling hole.
