At the 17th International Fire Show held in Beijing, exhibitors from more than 30 countries and regions brought in the world’s most advanced fire-fighting equipment, especially from China’s enterprises, displaying “artifacts” that solved the problem of urban fire safety. ".

High-rise fire extinguishing artifact unveiled at International Fire Show

Long arm fire engine "Where do you play?"

In terms of span, domestic fire engines have made new breakthroughs. In the Sany Heavy Industry Exhibition Area, the big guy with six joints is particularly eye-catching. Unlike a straight arm fire truck, its boom is free to bend and bend. It is reported that this is a large-span high-elevation jet fire engine jointly developed by Sany Heavy Industry and Beijing. Its "long arm" can span various obstacles such as fences, trees, and bungalows. The boom can be moved flexibly to maximize the size of the terminal outlet. The limit is close to the source of fire and realizes "where does it go?"

According to Chen Tianming, director of the Sany Heavy Industry Fire Fighting Equipment Project, with a large-span high-emission fire engine, rescue forces can easily overcome obstacles and reach the core of the fire. For fire rescue situations in narrow streets and lanes, large-span high-emission fire engines can extend four legs to support them at any position. The minimum support width is only 3.3 meters, which facilitates the rapid deployment of booms for fire rescue.

It is reported that the 48-meter long span jet-propelled fire engine has been tested in Beijing, and a 62-meter-long-span high-emission fire engine will also be officially delivered to the Beijing Municipal Fire Bureau to protect Beijing's fire safety.

Fire water 1000 meters a pump to the top

Although the lifting height of various types of fire engines continues to increase, the maximum height that can be reached by fire engines is currently 200 meters. The burning portion of more than 200 meters can only be saved through the built-in fire-fighting equipment inside the building. Therefore, the reliability of the internal water supply system of the building is very important.

However, the current centrifugal water pump can only send the water to a height of about 80 meters, so every 80 meters or so, a pump room should be set up in the building to transport water to the roof in a relay manner. In the event of a fire, if there is a problem with power outages or any part of the pipeline, it will be difficult for fire fighting water to be transported to high places.

At this exhibition, the world’s first ultra-high pressure fire-fighting pump developed by Sany Heavy Industry debuted for the first time. Although the size is small, only a fixed riser can be installed in the building to ensure that a 1,000-meter high-rise fire-fighting water supply can be pumped to the top. The current major high-rise building fire problems.

It is reported that this set of equipment uses full hydraulic piston pump set, the water pressure reaches 12 MPa, the maximum flow of double-unit equipment water supply up to 3,000 liters per minute, can expand the device to achieve an increase in flow. In addition, the diesel engine's independent drive mode does not depend on the power grid in the building, and even if power is cut off, it can operate normally.
