Structure and Principle
Semi-fixed or portable foam extinguishing device comprises wheel frame, foam vessel, PHF series proportioner, PQ4 or PQ8 tube gun and 65 type fire hose.
For PY series foam extinguishing devices, when in use, pressure water is supplied from fire hydrants or fire pumps. After being mixed in the proportioner, the foam solution is sent to foam tube guns to inject foam to extinguish fire of flammable liquids. It is suitable for the following occasions: oil tanks and refineries, petrochemical enterprises, aircraft hangar, port area, cargo storage yard, warehouse filling station and paint storage area.
Advantages
The vessel of PY Series Foam Extinguishing Device has excellent corrosion resistance, and is suitable for both normal foam solution and all kinds of foam extinguishing agents for Class B fire such as AFFF agent and others.
PY series Foam Extinguishing Device has strong maneuverability, which ensures quick and convenient transportation and deployment to the fire scene.
PY Series Semi-fixed or Portable Foam Extinguishing Device is manufactured and inspected in tight conformity with General Technical Specifications for Foam Fire Extinguishing Systems and Components, GB20031-2005, new National Standard, and has passed the pattern examination by Chinese National Fire-fighting Equipment Quality Supervision Testing Center (NFFE).
