Fire sprinkler

Function introduction: Fire sprinkler, also known as fire sprinkler, sprinkler fire truck, forest fire sprinkler, school fire sprinkler, airport fire sprinkler, community fire sprinkler, street and township and village sprinkler function. It is a dual-purpose vehicle that combines a fire truck and a sprinkler. It is a fire-fighting sprinkler integrated between a fire truck and a sprinkler. Compared with a fire engine, it lacks an equipment box, but it has a range with a fire engine. The same, with the same fire fighting function. Compared with the sprinkler, it inherited all the functions of the sprinkler and also made up for the problems of small range and low pressure of the sprinkler. In addition to fire-fighting pumps and equipment, fire sprinklers also have large-capacity water storage tanks, water guns, and water cannons. Water and firefighters can be transported to the fire to fight fires on their own. It can also directly save water from water sources, or supply water to other fire engines and fire suppression devices. Better than the function of the fire truck: Because there is no fire truck equipment box, the height of the chassis and the width of the vehicle are more suitable for road conditions in mountains, townships, and villages. It is an advantageous fire-fighting tool for forest firefighting, township and village firefighting.

Fire Sprinklers Install fire engines, special fire pumps, fire monitors, and firefighters. After the tank is equipped with a working platform, a green sprinkler can be installed on the platform, and the sprinkler can be rotated in all directions. The sprinkler can be sprinkled before and with side spray, and can be continuously adjusted into direct current, fog, heavy rain, light rain, drizzle, and safety fence. . Install fire hoses on the top of the tank. With fire protection interface, can enter the water through fire hydrant, with self-flow valve, fire greening reel.

Applicable to landscaping, highway watering, fire fighting, mine dust, living area fire, power plant fire, in water-deficient areas can also be used for water supply, water transport vehicles, suitable for fighting a general fire, is the public security fire brigade, enterprises and institutions full-time fire Teams, schools, forest fire departments, airports, factories, and mine-provided fire fighting vehicles can also be used as spray trucks when needed.

Before reading the instruction manual in detail, master the operation essentials. The following items should be used in the application:

(a) Water requirements:

Fire hydrant water injection: It should be noted whether the fire hydrant water supply pressure can meet the fire truck needs.

Retrieving natural water sources: When using river ravines and ponds as water sources, the end of the suction pipe should be completely submerged in water. In order to avoid inhalation of stones or debris and cause equipment damage, the end of the suction pipe is provided with a debris filtering device. It is forbidden to remove the filter device and pay attention to the water depth of the river pond to prevent the interruption of the water intake due to the shallow water source causing the suction port to be affected by debris or air.

(2) Precautions for sprinkler operations:

Fire sprinkler vehicles have a relatively low position of the front flushing device and should avoid obstacles during vehicle operation to avoid damaging the equipment.

(3) Fire extinguishing precautions:

1. After the fire sprinkler vehicle enters the fire, it shall stop the vehicle at the location designated by the fire commander. The parking posture of the vehicle can meet the needs of attacking and retreating the fire field, and it must be ensured that the dangerous position can be withdrawn at any time. The engine of the vehicle must remain in operation. It must not be turned off blindly and the fighter should be delayed. When the fire truck starts to supply water, the water pressure should be gradually increased to avoid the casualties of the combatants caused by the reaction force of the water gun or the explosion of the hose, which will affect the smooth development of the fire fighting and rescue work.

2. When the source of water is beyond the fire station's direct water supply capacity, the fire-fighting vehicle relay water supply method shall be used to supply the fire field. The driver of the water supply vehicle should pay attention to the overflow of the overflow pipe of the water truck and maintain the proper water supply. When the rear vehicle cannot observe the overflow condition of the preceding vehicle, the driver of the preceding vehicle can open the manhole in the upper part of the tank of the vehicle to prevent the tank rising phenomenon caused by the excessive supply of water. In the process of water supply, the receiving vehicle should choose a hard surface for parking. When it is impossible to park a hard surface, necessary measures should be taken to prevent the vehicle from falling into the quagmire due to overflow. When direct coupling water supply is used, the same type of fire fighting vehicle should be used as much as possible, and each vehicle must coordinate with each other to prevent water supply from being interrupted due to improper operation. When the direct water supply pressure is high, care should be taken to maintain proper water pressure to prevent injury to the combatants.

3. When using fire hoses to extinguish or remotely supply water, when pressured water flows in pipelines and fire hoses, due to the rapid closure of fire-fighting valves, fire hydrants, water guns, etc. The water flow in the fire hose immediately stops flowing, causing instantaneous increase in the water pressure in pipes and fire hoses. The effect of the increased water pressure on pipelines, fire hoses, and the like is the same as hammering. This phenomenon is called Water hammer effect. The pressure generated by water hammer to form pipes and fire hoses can reach several or even hundreds of atmospheres, causing damage to pipelines, fire hoses and other fire-fighting equipment and equipment, and directly affecting the fire rescue work. Therefore, in the fire rescue, it must prevent the occurrence of water hammer.

(d) Winter water release:

Fire sprinklers are always ready for battle due to the need of fire fighting characteristics (liquid tank full load). In winter, when the ambient temperature of the equipment is at minus zero (except for the hothouse), the water tank and the fire pump ball valve must be closed to cut off. Water source, at the same time, open the fire pump, power take-off device, fire monitor and fire control tennis valve discharge switch to eliminate residual water, so as to avoid freezing equipment

Cold Syndrome 1: The door cannot be opened

Description of the illness: The snow seeps into the cracks in the car. Under the effect of low temperature at night, the car door key hole or door is frozen, the key cannot be inserted, or it is inserted but it cannot be moved; exhausted the whole body strength, the door Can't open it either.

Wrong way: Use hard to twist the key or open the door.

Symptomatic medicine: If you force the key or hit the car door may be counterproductive, the key may be damaged. If you beat the door, the paint will be damaged. It is recommended that a bottle of warm water (hot water may burst the glass) be poured from home into the icing area. If you have a lighter on your hand, you can burn it at a distance from the door. The most basic method can be used to warm up, of course, the time will be longer.

Prevention tricks: You can inject a little lubricating oil into the door lock hole in advance, and apply a thin layer of grease on the sealing strip around the door.

Chilling II: Window Covered with Snow

Description of the illness: Heavy snow covered the front window so that it completely blocked the sight of the vehicle.

Wrong way: Start the wiper to remove snow.

Symptomatic medicine: As the name implies, the wiper wipes the rain. If the snow covered by the window is thick and even ice has been formed, using a wiper will cause serious damage to its rubber strips and other plastic parts. It is recommended that the car be equipped with a special glass snow shovel or a hard plastic blade to remove ice and snow. Avoid scratching the glass when removing snow and ice. It should be moved in the same direction. Do not scratch back and forth. If the snow is thin, you can enter the car, adjust the air conditioning warm air gear, and set it into a front wind mode. After a few minutes, the snow and ice can evaporate. In addition, some high-end cars are equipped with a rearview mirror heating function, which will solve the problem of rearview mirror icing soon after opening.

Prevention tricks: If you can only park your car outdoors, you should choose a sunny, dry place. When the vehicle is parked with its front facing away from the wind, it can reduce the amount of snow covered by the car body. If necessary, stop at night to support the wiper blade to ensure it will not be frozen.
