â— Fire engines Also known as fire trucks, they are vehicles designed for fire fighting or other emergency rescue purposes. Fire trucks can be divided into pump trucks, ladder trucks and other special vehicles according to their functions.
Fire engines in most areas are sprayed with bright red (in some areas there are bright yellow fire engines), and there are siren and flashing lights on the roof. The fire truck is the general name for all types of fire-fighting vehicles equipped with various types of fire-fighting equipment and fire-fighting equipment. It is currently the main tool for fire fighting and fire fighting, and is the most basic mobile fire-fighting equipment.
â— Many types of fire trucks are divided into the following types: fire tank trucks, foam fire trucks, carbon dioxide fire trucks, dry powder fire trucks, and foam-dry powder fire trucks. Water Tank Fire Truck Water Tank Fire Truck In addition to equipped with fire-fighting pumps and equipment, there are also large-capacity 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. Water transport vehicles, suitable for fighting general fires, are fire-fighting vehicles reserved for public security fire brigade and enterprises and professional fire brigades.
Notes for Water Tank Fire Engine 1. Signage Product label The product label shall be fixed under the left door in the cab. The product label must have the following content:
a. Product name and model b. Fire pump flow c. Water tank capacity d. Factory serial number e. Date of manufacture f. Manufacturer name 2. Packaging The following technical documents should be installed at the factory and properly packaged:

Exposed chrome pieces should be coated with rust-proof oil. Outside lights and warning lights should be wrapped with plastic film. Engines and fire pumps must not have excess water. Fuel tanks must not have residual oil, and batteries should be disconnected from the positive and negative terminals.
3. Transportation When using a transport box, the instructions for use of the new vehicle must be observed in the instructions for use. When iron (water) roads are used for transportation, relevant regulations for rail (water) road transportation should be implemented.
4. Storage When the water tanker is required to be stored for a long period of time, fuel and water should be drained, parked in a place that is fireproof, rainproof, moisture-proof, sun-protected and well-ventilated, and maintained and maintained in accordance with the instructions of the product manual.
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.
The special function description of the fire truck The overall flow line design, novel appearance, the water pump adopts the sandwich power method, to achieve the marching, fire synchronization 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.
â— Dry powder fire truck dry powder fire truck main equipment Dry powder fire extinguishing agent tank and complete set of dry powder injection device, fire water pump and fire fighting equipment and other foam-dry powder fire truck, mainly use dry powder to fight flammable and flammable liquids, flammable gas fire, live equipment fire It can also save fire from general materials. For large-scale chemical pipeline fires, the effect of fighting is particularly significant. It is a fire engine reserved for petrochemical companies.
The main equipment is dry powder fire extinguishing agent tanks and dry powder spraying devices, such as fire-fighting water pumps and fire-fighting equipment. The main use of dry powder is to save flammable and flammable liquids. Combustible gas fires and live equipment fires can also save fires from general materials. For large-scale chemical plant fires, the effect of fighting is particularly significant. It is a fire engine reserved for petrochemical companies.
Maintenance of dry powder fire trucks Dry powder fire trucks need 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.
â— Foam fire trucks Foam fire trucks are mainly equipped with fire-fighting pumps, water tanks, foam tanks, foam mixing systems, foam guns, cannons and other fire-fighting equipment that can independently put out fires. It is especially suitable for fighting oil fires such as petroleum and its products, and it can also supply water and foam mixture to fire sites. It is a necessary fire-fighting vehicle for petrochemical companies, oil terminals, airports, and urban professional fire brigades.
High-power foam fire-fighting vehicles are equipped with high-rate foam generating devices and fire pump systems. It can quickly spray 400-1000 times of a large number of high-multiple air foam, so that the combustion surface and the air insulation, play suffocation and cooling effect, and can eliminate some of the smoke, suitable for fighting the basement, warehouses, ships and other closed or half Closed building fires have a significant effect.
The proper use of foam fire engines (gunners) in fires is the basis for extinguishing petrochemical fires.
Foam fire trucks (gun cars) are necessary equipment for fighting fires in oil, chemical, factories and mines, and port cargo yards. Because it also has the performance of a tank fire truck, proper use of a foam fire engine is a matter worthy of attention for every fire commander. Due to the special performance of foam fire trucks, it is determined that most of the fires faced by such fire engines are petrochemicals and other dangerous fire sites. Such fires have the characteristics of high burning speed, many changes in the fire conditions, high probability of explosive combustion, and large threats to fire engines and combat personnel. Therefore, in order for the foam fire truck to reach a favorable position on the fire, it can quickly start fire fighting. Must pay attention to the following points:
1. The foam fire truck should face the fire from the side and back, and quickly discharge water to an appropriate pressure. (For example, the Dongfeng fire truck uses ≥0.686MP when using the PQ8 gun and ≥0.785MP when using the vehicle gun.) Pressure water cock, then open the bubble tank outlet ball valve, the mixer is adjusted to the appropriate position, aimed at the center of the flame, spray foam liquid.
2. When the use of foam guns for close combat, fire engines should be given the necessary protection according to the fire situation. The body can be covered with asbestos cloth and covered with water mist when needed.
3. During the entire fire fighting process, the driver must stick to his position, constantly pay attention to the immediate amount of foam liquid in the vehicle, and add foam liquid in time. Once the foam liquid is used up and refilled, it will inevitably affect the entire fire fighting action.
â— Carbon dioxide fire trucks High-pressure gas cylinders equipped with carbon dioxide extinguishers and complete sets of injection devices are equipped on the vehicles, and some fire-fighting pumps are also provided. It is mainly used to save valuable equipment, precision instruments, important cultural relics, book archives and other fires, and it can also save general material fires.
â— Foam-dry powder fire truck The equipment and extinguishing agent on foam-dry powder combined fire trucks are a combination of foam fire truck and dry powder fire truck. It can spray different fire extinguishing agents at the same time, and can also be used alone. Suitable for fighting combustible gases, flammable liquids, organic solvents, electrical equipment, and general material fires.
â— The purchase of fire engines The purchase of fire engines can be 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 purchase relatively comparable models. For example, large-scale finished fuel tanks can be purchased for foam fire engines and dry powder fire engines. The school community can buy water tank fire engines on it.

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 production unit and reputation of the power takeoff, the pressure power of the fire pump 2. The assembly sealing degree of the heat insulation plate 3. The setting of the storage compartment inside the instrument and equipment box and the implementation of related equipment 4. It is characterized by its Large-capacity water storage tanks are also equipped with fire-fighting pump systems, which are used as back-up vehicles for water supply on fire sites and are particularly suitable for arid and dry areas. It also has the function of a general water tank fire truck.
