Fire engine accessories knowledge of water gun

For the fire engine, I believe that not many people know, usually people only remember the appearance, the inner part of the understanding is less. For example, the fire engine on both sides of the aluminum alloy rolling shutter door inside the fire equipment, it is equipped with rich, and different configuration is not the same. That for some non-professional fire brigade or just established fire station users, not only to understand, the use of fire equipment, but also to each fire equipment use and classification understand clearly. The following is the Fire Truck factory for you to explain about the fire engine accessories of the water gun related knowledge, for everyone to understand:

The fire fighting equipment on the fire truck are: Air foam gun, water gun, fire suction pipe, water filter, water distributor, fire hose, hose hook, hose package cloth, reducing interface, the same type of interface, DC water gun, fire hydrant transition joint, blossom water gun, DC switch water gun, ram pick, ground wrench, suction pipe wrench, guard bridge, mixer suction pipe, waist axe, fire ax, shovel, crowbar, etc.

Dc water gun is one of the most commonly used water gun in fire fighting. It is composed of nozzle, barrel and pipe tooth interface. The nozzle caliber of water gun is 13, 16, 19, 22, 25mm, etc. Direct current water gun is used to spray dense water, suitable for fighting outdoor fires. It is characterized by long range and large flow rate.

Switch DC water gun It is very easy to understand, is equipped with a switch on the DC water gun, its jet is also dense, compared to the DC water gun, the water gun has a switch, can be opened and closed at any time, and can control the size of the water flow, therefore, the switch DC water gun is more suitable for fighting high, far and indoor fire. When using the switch DC water gun, attention should be paid to slowly open or close, otherwise the sharp impact of the water may cause water rupture or personal accident. Note that in the cold weather in the north, the water gun should not be turned off for a long time to prevent the switch device from freezing and failing.

Flowering direct current water gun: It is used to spray dense and enriching water, it can also spray flowering water according to the need of fire fighting, used to cool the outer wall of the container, block radiation heat. Shield the fire crew from the ignition. The structure of the flowering DC water gun is characterized by two kinds of switching devices in the barrel. One is the DC regulating valve, which controls the DC jet; The second is the flowering regulating valve, which controls the flowering jet. After the water enters the barrel, it flows in two ways, one way is the middle of the barrel leading to the DC nozzle, and the other way is through the pipe wall leading to the opening regulating valve. Its fineness is related to the size of the water pressure, the pressure is large, the water drop is small. Small pressure, big water drop. The water gun can be used to fight indoor fire or cover the combatant to extinguish the fire, the operation of the switch valve to the right turn to open, the opposite direction is closed, the use of flowering, left rotation flowering regulating valve is open, the opposite direction is closed.

Spray water gun is divided into centrifugal spray water gun, pulse pressure spray water gun, spring spray water gun, multi-function DC spray water gun, etc. A double centrifugal nozzle is installed on the spray water gun, so that the water flow sent by the fire pump becomes a mist flow under the action of centrifugal force, so it is called spray water gun. Spray water gun is suitable for small area oil fire and oil invasion type transformer and other electrical equipment fire. Spray guns can also absorb a lot of radiant heat, and are great for fighting indoor fires or shielding firefighters from heavy smoke.

Water gun with bracket is a large caliber water gun fixed on a special bracket, known as water gun with bracket. It is a larger flow and a longer range. The rotating disc with a water gun can rotate 360 degrees horizontally and 90 degrees up and down. It is easy to operate and can reduce the labor intensity of operators. The water gun is suitable for large area fire, high-rise building fire, there is a risk of explosion and difficult to access the fire. But because of this water gun impact device, in the process of use, should prevent the building structure broken and collapse and water damage loss.

Air foam gun is mainly composed of nozzle, opening and closing handle, barrel, hand wheel, gun body, sealing ring, straw, straw joint and pipe tooth interface. Mainly used to fight small and medium-sized oil fires. The air foam gun is characterized by good performance, small size, light and flexible, easy to use. The foam gun is equipped with a circular handwheel that is easy to operate and plays the role of protecting the gun. The operator should hold the handwheel of the gun while using it. At the same time, it should pay attention to the pressure of the water or mixed liquid supplied to the gun should be gradually increased, but should not exceed the range of using pressure, so as to avoid the injury to the operator caused by sudden impact or high pressure. Try to spray along the wind direction, avoid crosswind and upwind spray.

As the main force of fire extinguishing, the fire engine plays an important role in the fire extinguishing work. As an important part of the fire engine, different types of water guns should be selected according to different types of fires in order to achieve better fire extinguishing effect. And the purchase must first understand the function of different types of water gun, so the purchase to be more appropriate.
