Isuzu fire trucks are equipped with a wealth of firefighting equipment, but few people understand the inner parts. For example, the aluminum alloy rolling shutter doors on both sides of the Isuzu fire truck are equipped with various fire equipment. However, for some non-professional fire brigades or newly established fire stations, they not only need to be familiar with and use these equipment, but also need to understand each equipment. uses and classifications. Below we will introduce to you the relevant knowledge about fire water guns in Isuzu fire truck accessories for your understanding.
The fire-fighting equipment on the Isuzu fire truck includes air foam guns, water guns, fire suction pipes, water filters, water distributors, fire hoses, hose hooks, hose wrappers, reducing interfaces, same-type interfaces, DC water guns, fire hoses, etc. Bolt transition joint, blooming water gun, DC switch water gun, sheep pick, floor wrench, suction pipe wrench, belt bridge, mixer suction pipe, waist axe, fire board axe, shovel, crowbar, etc.
The DC water gun is the most common type of water gun used in fire extinguishing. It consists of a nozzle, a barrel and a pipe tooth interface. The nozzle diameter of the water gun can be of different sizes such as 13, 16, 19, 22, and 25mm. DC water guns are used to spray dense water flow and are suitable for extinguishing outdoor fires. They have the advantages of long range and large flow rate.
The switch DC water gun is a water gun with a switch installed on the DC water gun. Compared with DC water guns, switch DC water guns have the same dense jet, but can be turned on and off at any time, and the size of the water flow can be controlled. Therefore, the switch DC water gun is more suitable for extinguishing fires at high places, distant places and indoors. When using a switch DC water gun, turn it on or off slowly to prevent the sharp impact of the water flow from damaging the hose or causing personal injury. In addition, in cold weather in the north, the water gun should not be turned off for a long time to avoid freezing and failure of the switch device.
The blooming DC water gun is used to spray dense and substantial water flow. It can also spray blooming water according to fire extinguishing needs. It is used to cool the outer wall of the container, block radiant heat, and cover the fire extinguisher's work around the fire source. The structural feature of the blooming DC water gun is that a DC regulating valve and a blooming regulating valve are set in the barrel. After the water flow enters the gun barrel, it is divided into two paths, one leading to the direct flow nozzle, and the other leading to the blooming regulating valve through the tube wall. The fineness of the flowering water flow depends on the water pressure. When the pressure is high, the water droplets are small, and when the pressure is low, the water droplets are large. Blooming DC water cannons can be used to extinguish indoor fires or cover combatant firefighting operations. When in use, turn the switch valve to the right to open, and vice versa; when using blooming water flow, turn the blooming regulating valve to the left to open, and vice versa to close.
Spray guns include centrifugal spray guns, pulse air pressure spray guns, reed spray guns, multifunctional DC spray guns, etc. The spray gun is equipped with dual centrifugal nozzles, which can convert the water flow supplied by the fire water pump into mist water flow, and is suitable for extinguishing small-area oil fires and oil-immersed transformer fires. Spray cannons can also absorb large amounts of radiant heat and are used to extinguish indoor fires or cover firefighters operating in thick smoke.
The water gun with a frame is a large-caliber water gun that is fixed on a special bracket, so it is called a water gun with a frame. The water gun with frame has the characteristics of large flow rate and long range. The rotating disc with water gun holder allows the water gun to rotate 360 degrees in the horizontal direction and 90 degrees in the up and down direction. It is easy to operate and can reduce the burden on the operator. This water gun is suitable for extinguishing large area fires, high-rise building fires and fires with explosion risks that are difficult to access. However, due to the strong impact of this water gun, care should be taken to prevent damage to the building structure, collapse, and rupture of the hose when using it.
The air foam gun consists of a nozzle, opening and closing handle, gun barrel, hand wheel, gun body, sealing ring, straw, straw joint and pipe tooth interface. It is mainly used to extinguish small and medium-sized oil fires. The air foam gun has good performance, small size, light and flexible, and easy to use. Its rounded hand wheel facilitates operation and protects the gun user. When using, the hand wheel should be tightened and the pressure of the water supply or mixed liquid should be gradually increased, but the pressure range should not be exceeded to avoid sudden impact or excessive pressure from causing harm to the operator. When spraying, spray in the direction of the wind and avoid spraying to the side and against the wind.
Isuzu fire trucks are the main force in fire-fighting operations, and fire water guns are an important part of them. When purchasing, appropriate water guns should be selected according to different types of fires to achieve the best fire-extinguishing effect. Before purchasing, you must first understand the functions of different types of water guns so that you can choose the right one.
