The series of dry powder fire extinguishers are produced in accordance with - standards. The cylinder is made of high-quality carbon steel and processed with special technology. This series of fire extinguishers have the advantages of simple structure, flexible operation, wide application, easy use, and low price. It is suitable for extinguishing the first fires of flammable liquids or meltable solids (usually referred to as fire-like), flammable gases (usually referred to as fire-like) and electrical equipment. It can also extinguish fires burning solid organic substances (usually referred to as fire-like). 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.
1. Structure and composition of the fire extinguisher
The fire extinguisher is mainly composed of a cylinder, a bottle head valve, a spray hose (nozzle), etc. The fire extinguishing agent is sodium bicarbonate (type ammonium phosphate) fire extinguishing agent driven The gas is nitrogen and its working pressure at room temperature is...
2. Main performance characteristics:
This series of fire extinguishers have the characteristics of high fire extinguishing efficiency and rapid fire extinguishing. The built-in dry powder fire extinguishing agent has the advantages of good electrical insulation, is not susceptible to moisture and deterioration, and is easy to store.
The driving gas used is non-toxic and odorless and will not harm the human body after being sprayed.
The fire extinguisher bottle head valve is equipped with a pressure gauge to display its internal pressure for easy inspection and maintenance.
3. Scope of use:
Suitable for extinguishing initial fires of flammable liquids and gases. It can also extinguish fires of electrified equipment. The medium-sized ones can also be used to extinguish fires of 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: - ℃ ~ + ℃. It should not be exposed to the hot sun, close to fire sources or subject to severe vibration.
Fire extinguishers should be placed in a secure storage location that is ventilated and dry.
Frequently check whether the safety pin and lead seal are intact and whether the pressure value meets the requirements and whether the parts are loose, deformed, rusted or damaged.
One year after the expiration of the fire extinguisher, regular maintenance should be carried out to check whether the bottle head valve, nozzle, etc. are damaged, check whether the cylinder is corroded, and conduct a hydrostatic test. Those that fail the hydraulic test should be scrapped.
Fire extinguishers should be repaired or refilled by qualified professional fire maintenance departments. Users are not allowed to disassemble or repair without authorization.
