The series of cart-type dry powder fire extinguishers are produced in accordance with - standards. It is a high-efficiency fire extinguisher with a large fire extinguishing range and high efficiency. Its unique spray The pipe fixing mechanism and the push-pull operating mechanism make the fire extinguisher flexible to operate and easy to use. It is widely used in industrial and mining enterprises, ships, oil depots, gas stations and other places with high fire risk.
1. The structure and composition of the fire extinguisher:
The fire extinguisher is mainly composed of a barrel, a head assembly, a nozzle assembly, a frame assembly and other parts. The fire extinguishing agent is sodium bicarbonate (type It is ammonium phosphate) dry powder fire extinguishing agent, the driving gas is nitrogen, and its working pressure at room 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 built-in dry powder fire extinguishing agent has the advantages of good electrical insulation, is not susceptible to moisture 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.
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. 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.
The fire extinguisher should be placed firmly and the storage location should be ventilated and dry.
. Frequently check whether the operating mechanism is flexible and convenient.
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.
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 test. Those that fail the hydraulic test should be scrapped. deal with.
Fire extinguishers should be repaired or refilled by qualified professional fire maintenance departments. Users are not allowed to disassemble or repair without authorization.
