) ) ' 1. Structure and composition of the fire extinguisher
) ) The fire extinguisher is mainly composed of a cylinder body, a head assembly, a nozzle assembly, a frame assembly and other parts. The fire extinguishing agent is Sodium bicarbonate (type ammonium phosphate) dry powder fire extinguishing agent, the driving gas is nitrogen, and its working pressure at normal temperature is.
)
) ) ' 2. Main performance characteristics
) ) This series of fire extinguishers have the characteristics of large fire extinguishing range, high efficiency and rapid fire extinguishing. The dry powder fire extinguishing agent inside has good electrical insulation. , not susceptible to moisture and deterioration, easy to store and other advantages.
) ), the driving gas used is non-toxic, odorless, and will not harm the human body after injection.
)) The fire extinguisher bottle head valve is equipped with a pressure gauge, which can display its internal pressure and facilitate inspection and maintenance.
)) The fire extinguisher is equipped with an operating mechanism for easy operation and use.
)
) ) ' 3. Scope of use
) ), suitable for extinguishing initial fires of flammable liquids and gases, and also for extinguishing fires in electrical equipment, of which type / can also be used Fight fires involving flammable solids. It is widely used in oil fields, oil depots, factories, shops, distribution rooms and other places. It is an essential fire-fighting equipment to prevent fires and protect people's lives and property.
) ), the operating temperature range is ℃ ~ + ℃.
)
) ) ' 4. Maintenance
) ) The storage environment temperature is ℃ ~ + ℃ and shall not be exposed to the scorching sun, close to fire sources, or subject to severe vibration.
)) Fire extinguishers should be placed firmly and the storage location should be ventilated and dry.
) ), always check whether the operating mechanism is flexible and convenient.
)), always check whether the safety pin and lead seal are intact, whether the pressure value meets the requirements, and whether the parts are loose, deformed, rusted or damaged.
). Five years after the fire extinguisher expires, every two years or before refilling, check whether the bottle head valve, nozzle, etc. are damaged, check whether the cylinder is corroded, and conduct a hydraulic pressure test. If it fails, should be scrapped.
)) Fire extinguishers should be repaired or refilled by a qualified professional fire maintenance department. Users are not allowed to disassemble or repair without authorization.
