Water Tanker Fire Truck Introduction In addition to equipped with fire pumps and equipment, the car also has a large-capacity water storage tank, water gun and water cannon. Water and firefighters can be sent 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 fighting equipment. Water supply is also available in water-scarce areas. Water transport vehicles, suitable for fighting general fires, are fire-fighting vehicles reserved for public security fire brigade and enterprises and professional fire brigades.
Classification of tank fire trucks According to the different types of pumps prepared for combat, the tank fire engines can be divided into ordinary tank fire engines, medium and low pressure pump tank fire engines, high and low pressure pump tank fire engines, and high and low pressure pump tank fire engines. The ordinary water tank fire truck adopts a single-stage or two-stage centrifugal fire pump, the head can reach about 110m-130m, and the flow rate is generally between 30-60/s. The low-pressure pump water tank fire engine is independently developed in China and is suitable for China's national conditions. It is composed of two centrifugal impellers in series. The low pressure head is 1.0mpa, the flow rate is 40/s, the medium pressure head is 2.0mpa, and the flow rate is 20/. s, is the main battle vehicle of the future firefighting force. The high and low pressure pump water tank fire truck is a kind of fire pump produced by introducing the Luxembourg sub-technique. The pump is composed of multi-stage centrifugal impellers in series. The impeller of the first stage is a low pressure impeller and the impeller of the rear stage is a high pressure impeller. The low pressure and high pressure can be At the same time, the high pressure head can reach 4.0mpa, the flow rate is 4000/min, the low pressure head is 1.0mpa, and the flow rate is 4000/min. The newly developed high-performance products of high- and medium- low pressure pump tank fire engines can not only perform low-, medium-, and high-pressure jet extinguishing, but also can be combined with low pressure and high pressure. At medium pressure, water can be supplied remotely, water can be supplied to high-rise buildings, or can be extinguished with high lifts. In addition, according to the water capacity of the tank fire truck, it can be divided into medium-sized tank fire engines and heavy-duty tank fire engines. At present, the water capacity of heavy-duty tank fire trucks has reached 18 tons, which is particularly suitable for use in water-scarce areas. [1] Water tank fire engines According to different volume requirements, water tank tanks can be divided into inner water tank tanks and exposed tank tanks. [2]

The function of each part of the water tanker fire truck In general, the fire water truck can be divided into four parts by function. The front part of the fire truck is the cab, and the driver and the commander sit in the cab; behind the cab are the positions of other firefighters. Behind the first roller blind is placed a variety of tools, including faucets, fire hoses, etc. These tools are followed by a storage tank for fire fighting water. Near the rear of the fire engine is a pump room. As the name suggests, this is where the pump for pumping water is placed. Generally, there are roller shutters on each side of the pump compartment. The screen that shows the working status of the pump can also be seen by retracting the rear roller shutter. In the pump room, there are usually tools necessary for using the pump. [Fire engine special function description] The overall flow line design, novel appearance, the water pump adopts the sandwich power method to achieve the marching, the fire extinguishing synchronous action, economical and practical, flexible, is a new generation of the same type of fire engine replacement products. This vehicle is suitable for small and medium-sized cities, fire brigades, fire brigades and township fire stations, and full-time fire brigades of communal enterprises to extinguish general fires. [Buy Fire Engine] The purchase of fire engines is divided into two main categories: the purchase of fire fighting vehicles, and the purchase of special-purpose fire engines. The purchase of fire-fighting fire trucks mainly refers to the fire-fighting vehicles in fixed operating environments such as warehousing, residential areas, commercial areas, special equipment storage areas, etc. Fire-fighting vehicles for all kinds of relatively predictable fire-fighting operations should be used. The majority of car-using units can be based on Actual job requirements and fire response facilities are to be purchased for relatively comparative models. For example, large-scale finished fuel tanks can be purchased with foam fire engines and dry powder fire engines. The school community can buy water tank fire engines on it. The purchase of special-purpose fire engines mainly refers to the special-purpose fire engines that deal with unpredictable emergencies. The purchase of such models should proceed from the overall situation, focusing on a multi-purpose vehicle function. For example, the optional use of urban fire brigade Ascends the function ladder ladder water cannon fire engine, the high speed road can choose to take the tow-in-the-wall type fire-breathing gun fire engine. While selecting the type of fire engine, the vehicle unit should review the manufacturing quality of the fire engine from the following points: 1. The power production unit and reputation, the pressure of the fire pump power. 2. Insulation plate assembly sealing degree. 3. The setting of the storage compartment inside the instrument and equipment box and the implementation of related equipment. 4. It is characterized by a large-capacity water storage tank and a fire-fighting pump system. It is used as a back-up vehicle for water supply in the fire field and is particularly suitable for arid and dry areas. It also has the function of a general water tank fire truck.
At present, the domestic mainstream tank fire truck tonnage is currently the domestic tank fire truck, with Dongfeng, Liberation, Heavy Duty Truck, Qingling and other chassis as the main carrier, and its tonnage is mainly divided into the following categories: 1. Dongfeng Xiaobawang water tank fire truck, 2 tons; 2. Small Isuzu tank fire engine, 2 tons; 3. Jiangling water tank fire truck, 2 tons; 4. Dongfeng Dolika water tank fire truck, 3 tons; 5.

Big Isuzu Shuangqiao Water Tank Fire Truck, 15 tons; 12. Four-eighth tank fire truck before Dongfeng, 20 tons.
Water Tanker Fire Truck Maintenance The fire truck needs regular maintenance to keep the vehicle condition normal. The average driver is often very big about maintenance. It is because he knows that the car will be opened soon without maintenance, but it is very painful to pay for maintenance. Under normal circumstances, oil is changed every 10,000 kilometers or once a year, brake oil is changed every two years, and gear oil needs to be replaced longer. In addition to these three kinds of oils have a relatively fixed maintenance mileage, what other clutch oil, power steering oil, water tanks, etc. are replenished or replaced as appropriate. The purpose of maintenance is inspection, and the purpose of inspection is prevention. In addition to the liquids mentioned above, there are some solid things in the car that need to be replaced. The most common ones are spark plugs and air filters. In general, platinum spark plugs are replaced once every 100,000 kilometers, and air filters are usually replaced by 40,000 kilometers. Then there is the timing belt and its idler gear set. Only the vehicles with timing belts need to be replaced. The engines with the timing chain design may not be replaced when they are used for scrap. The replacement of the timing belt is the most expensive one in normal maintenance, and it must not be saved. In fact, so few things need to be replaced, because the real purpose of maintenance is not to replace these consumables, but to check whether the vehicle is abnormal. Many people have a misconception that maintenance is an oil change. However, in fact, replacing oil has never been the focus of maintenance, at most, it is nothing more than routine business. The main purpose of maintenance is to check and check if there are any parts on the car that are damaged or need to be adjusted. The actions during these inspections will ensure the safety of your driving. There are many inspection items, which are generally part of the inspection engine, the exterior of the car body, and the chassis. Open the hood to check the water tank, oil, gearbox, hydraulic steering wheel hydraulic oil, brake oil, wiper water, batteries, belts, air filters, etc., then check the wipers, wiper flusher heads, the whole car lights, and then Check the brakes and hand brakes, tires, drive shafts, shock absorbers, and various oil seal cushion rubber pads, and pay attention to whether the vehicle bottom abnormal oil and various abnormal phenomena. Oil and oil filters are something that must be changed every time. Before changing the oil, you should first take out the oil scale and check whether the oil is consumed and whether the viscosity is normal or not. In addition to paying attention to the normal amount of water, the tank water should also pay attention to whether the water color is normal. When the tank water is abnormally dirty, the tank water must be completely renewed. Transmission oil is generally the same as checking the amount of oil and color, power steering oil. In addition to changing the brake oil every two years, each time the maintenance must check the amount of oil and color, when the height drops a little when it is not anxious to add, it is because of the brake pads caused by the wear and tear caused by the brake pump, replaced with new To make the amount of oil will rise. There are two kinds of batteries for fire engines, one is water-free, and the other is traditional water. The water-free type usually depends on the check mark. The traditional water-filled type battery must be filled with pure water to the full water level. Check the battery is usually used to check the battery checker, when the battery voltage drop is too much, on behalf of the battery aging need to be replaced, the battery life is usually two years. The air cleaner core is generally a 40,000-kilometer change, but it will be checked every time it is repaired to avoid damage. The last thing to check is the exhaust pollution. Usually this is off and it means no problem with the engine. Chassis inspection is usually the most difficult to do, because there is no top car machine, brake force testing machine and other equipment. The most important brake inspection is the brake force. Generally, the vehicle should be more than 80% of the vehicle weight. The second is to check the film thickness so that the film thickness is less than 2mm and it needs to be replaced immediately. The tires are to be checked for tire pressure, wear, eating and aging. Tire pattern 1.6mm will be replaced immediately. When you eat the tire, you must check the position. The tire aging also needs to be replaced. Even if the tread pattern is very deep, the tire will lose its elasticity and grip due to aging under ultraviolet light. Usually, the tire is not recommended for use. More than 4 years. Then there is the inspection of the transmission and suspension system at the bottom of the vehicle. Basically it is to check whether there is any damage to the oil seal or whether there is any abnormal oil leakage.
Leakage of fire trucks At present, domestic fire engines are divided into a large number of chassis, including Dongfeng, JMC, Isuzu, and CNHTC. [3] The main configuration of the tank fire truck is: fire pump, storage tank and water gun (water cannon), faucet, fire hose, pump compartment near the rear of the fire truck. If you choose a fire engine, you can check the quality of the fire engine through the following parts of the fire engine: the production unit and reputation of the power takeoff; the pressure power of the fire pump; the degree of assembly and sealing of the heat insulation plate; The establishment of objects and the implementation of related equipment; large-capacity water tanks and fire pump systems for fire engines. 1. Check that the tank lid is fastened. 2. Test the gas into the tank to see where the tank water is seeping when it is pressurized, and then decide on a remediation plan. 3. Unscrew the lid of the engine plus oil to see if there is any trace of inorganic oil emulsification (punch or corrosion phenomenon). If so, disassemble the engine and replace the cylinder head gasket. 4. There is a problem with the quality of the water tank. If the car is in the process of driving, due to vehicle vibration or vehicle accidents, if the tank water pipe ruptures and leaks, measures can be taken according to specific conditions: When the water leakage does not exceed 1mm crack or 2mm hole, add a bottle of water tank blocking agent to the tank to start the car. 5~10 minutes after the cooling water is turned on, the cooling system will be leaking at the leaking water (or antifreeze) regardless of whether it is a water tank or a rubber pipe and all mats. The leak will not be released after the leak is stopped, and the heat dissipation will not be affected. Blockage occurs. If there is no anti-leakage agent to carry, the individual heat pipe leaks lightly, and the loose tobacco can be temporarily put into the water tank to make use of the circulating pressure of the water to make the tobacco block plug in the leaking part of the heat pipe and temporarily use it. For water tank cooling pipe leakage is more serious, you can cut the leaky heat pipe from the leak, with a soap coated cotton mass cut off the heat pipe, and then use the pliers to cut flat heat pipe head flattened and then crimped Press tight to stop leaking. If the rubber pipe joint is leaking, use a screwdriver to wrap the rubber pipe joint clamp in the rubber pipe joint and then tighten it with pliers. If the rubber tube is damaged, use a tape to wrap it tightly and temporarily use it.
Cautions for the use of water tanker fire trucks : The tank fire truck is a special vehicle used for fire fighting or other emergency rescue purposes. Fire engines in the use of different situations pay attention to the following: (1) Several issues that should be noted in the operation of fire-fighting vehicles when they enter the fire scene and put them into fire-fighting rescue operations. 1. After the fire-fighting 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, in the process of access to water, it should pay attention to whether the fire hydrant water pressure can meet the needs of fire engines. When accessing natural water sources, attention should be paid to the water depth of the ponds and ponds, silt, etc. to prevent excessive shallow water depths and the intake of intake pipes from being affected by silt and causing water supply interruptions in the fire site. 3. When the water source is beyond the fire station's direct water supply capacity, the fire truck 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. Each vehicle must coordinate with each other to prevent the 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. (2) After the fire trucks go to the fire and reach the fire, they must occupy a favorable position for fire extinguishing and quickly put into combat operations. 1. The fire engine must ensure safe and rapid driving during its journey to the fire. The fire truck should choose to travel from the nearest fire engine access to the fire. When more than one vehicle is out of the police, each workshop maintains a sufficient safety distance (50 to 80 meters is appropriate). After arriving at the fire scene, avoid multiple vehicles entering the same combat area at the same time to prevent the fire commanders from mobilizing the vehicles and putting them into fire fighting in time to delay the fighter. 2. The fire engine driver must resolutely obey the command of the fire commander on the fire field, wittily and flexibly execute the order of the commander to ensure the smooth implementation of the entire fire fighting. In the event of an irreversible change in the fire and a direct threat to the safety of the fire truck, the vehicle can be transferred to a safer place and continue to be put into combat, and the vehicle parking position can be promptly reported. (c) to prevent the occurrence of water hammer. When pressured water flows in pipelines and fire hoses, due to the rapid closure of fire-fighting valves, fire hydrants, water guns, etc., and the weight of the vehicle, the water pressure in the pipes and fire hoses stops flowing instantaneously. The water pressure in pipelines and fire hoses rises instantaneously. The effect of increased water pressure on pipes, fire hoses, etc., is the same as hammering. This phenomenon is called water hammer. Water hammer to form a pipe, the pressure within the fire hose can reach several or even hundreds of atmospheric pressure? Cause pipelines, fire hoses and other fire equipment, equipment damage, a direct impact on the fire rescue work. Therefore, water hammer must be prevented from happening in fire rescue. [4]

The low pressure and high pressure can be At the same time, the high pressure head can reach 4.0mpa, the flow rate is 4000/min, the low pressure head is 1.0mpa, and the flow rate is 4000/min. The newly developed high-performance products of high- and medium- low pressure pump tank fire engines can not only perform low-, medium-, and high-pressure jet extinguishing, but also can be combined with low pressure and high pressure. At medium pressure, water can be supplied remotely, water can be supplied to high-rise buildings, or can be extinguished with high lifts. In addition, according to the water capacity of the tank fire truck, it can be divided into medium-sized tank fire engines and heavy-duty tank fire engines. At present, the water capacity of heavy-duty tank fire trucks has reached 18 tons, which is particularly suitable for use in water-scarce areas. [1] Water tank fire engines According to different volume requirements, water tank tanks can be divided into inner water tank tanks and exposed tank tanks. [2]

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. Each vehicle must coordinate with each other to prevent the 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. (2) After the fire trucks go to the fire and reach the fire, they must occupy a favorable position for fire extinguishing and quickly put into combat operations. 1. The fire engine must ensure safe and rapid driving during its journey to the fire. The fire truck should choose to travel from the nearest fire engine access to the fire. When more than one vehicle is out of the police, each workshop maintains a sufficient safety distance (50 to 80 meters is appropriate). After arriving at the fire scene, avoid multiple vehicles entering the same combat area at the same time to prevent the fire commanders from mobilizing the vehicles and putting them into fire fighting in time to delay the fighter. 2. The fire engine driver must resolutely obey the command of the fire commander on the fire field, wittily and flexibly execute the order of the commander to ensure the smooth implementation of the entire fire fighting. In the event of an irreversible change in the fire and a direct threat to the safety of the fire truck, the vehicle can be transferred to a safer place and continue to be put into combat, and the vehicle parking position can be promptly reported. (c) to prevent the occurrence of water hammer. When pressured water flows in pipelines and fire hoses, due to the rapid closure of fire-fighting valves, fire hydrants, water guns, etc., and the weight of the vehicle, the water pressure in the pipes and fire hoses stops flowing instantaneously. The water pressure in pipelines and fire hoses rises instantaneously. The effect of increased water pressure on pipes, fire hoses, etc., is the same as hammering. This phenomenon is called water hammer. Water hammer to form a pipe, the pressure within the fire hose can reach several or even hundreds of atmospheric pressure? Cause pipelines, fire hoses and other fire equipment, equipment damage, a direct impact on the fire rescue work. Therefore, water hammer must be prevented from happening in fire rescue. [4]
