PHP Series of Pressure Balancing Foam Proportioning Device1. Overview
The PHP series of pressure balancing toam proportioning device (hereinatter referred to as PHP) is relatively advanced large-scale foam fire-extinguishing equipment in China.According to the driving mode, PHP can be divided into hydraulic turbine drive, motor drive. and diesel engine drive,and can also be mixed drive.PHP is a new type of foam fire-extinguishing device that provides foam solution to foam fire-lighting devices. The foam solution can be continuously replenished during the system work. The large foam concentrate storage and high reliabiity and stabilty can greatly improve the fire extinguishing capacity. Today. large-scale foam fire-fighting projects have higher requirements for the supply of foam solution. The limited foam solution supply of the traditional pressurized foam proportioning devices has become more and more unsuitable tor modern large-scale toam fire-lighting projects.PHP is a new type of foam fire- extinguishing device that provides to a solution to foam fire-tightind evice Ⅱ1. Advantages and Structure 1.The proportioner adopts an integrated structure (the balance valve and the proportioner are integrated). with a simpler appearance and relatively reduced volume, which optimizes the system space.
2.The ingenious internal structure design features the wider working pressure range. the bigger flow range. and the more accurate mixing ratio.
3.The material of the storage tank, foam pump and pipeline are all stainless steel, and PHP is equipped with a back washing device to avoid rust and corrosion.
4.Al instruments that measure pressure and liquid level adopt bus instruments for centralized monitoring; the valves all display position signals, making the operation intuitive and easy to control.5. Foam solution can be added at any time during the fire extinguishing. which is convenient to use,and the maintenance is simpler; Ⅲ.Application Range This system is mainly suitable for important fire hazards such as large petrochemical industry, large logistics warehouse, crude oil terminal, airport (depot), offshore platform, substation, loading and unloading area, etc.
