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 foam proportioning device is the most common foam extinguishing equipment at present. The pressure type foam proportioning device is easy to install, use and maintain. The built-in capsule has excellent corrosion resistance. The cost is relatively affordable, and the equipment performance is stable and reliable. It is especially suitable for medium and small flow foam fire extinguishing systems. Mainly suitable for the production, storage, transportation, and use of flammable or combustible liquids; Places with fire hazards such as petrochemical enterprises, oil depots, loading and unloading docks, ship terminals, oil extraction platforms, aircraft hangars, and car garages. The pressure type foam proportioning device can be divided into horizontal, vertical, single proportioning mixer, double proportioning mixer, etc. according to the structure type, and users can choose according to the actual configuration needs and the location of the installation space. The horizontal foam tank (PHYM pressure type proportional mixing device) produced by Shandong Dongyue Crane Fire Fighting Equipment Manufacturing Co., Ltd. has a capacity ranging from 1000L to 10000L, and there are also differences in flow. Customers can purchase it according to their own needs. The company also produces various types of vertical foam tanks (PHYML pressure type proportional mixing device), which is also a fixed foam fire extinguishing system, with capacities ranging from 1000L to 3000L and different flows.
