Fire engines, also known as fire engines, refer to special vehicles mainly used to perform fire response tasks, including most countries, including China, the fire department will also be used for other emergency rescue purposes. Fire trucks can transport firefighters to the scene of a disaster and provide them with a variety of tools to perform disaster relief tasks. Modern fire trucks are usually equipped with steel ladders, water guns, portable fire extinguishers, self-sustaining breathing apparatus, protective clothing, demolition tools, first aid tools and other equipment, some will also be equipped with water tanks, pumps, foam fire extinguishing equipment and other large fire extinguishing equipment. Most areas of the fire truck appearance is red, but there are some areas of the fire truck appearance is yellow, some special fire trucks are also so, the top of the fire truck is usually equipped with alarm sirens, alarm lights and flash lights. Common types of fire trucks include water tank fire truck, foam fire truck, pump fire truck, climbing platform fire truck, ladder fire truck and so on.

Fire engine maintenance method:

1, routine maintenance.

(1) The combat-ready fire engine must be pressurized to travel safely. A few hours after pumping enough gas or the next day to see whether the barometer is safe to exercise. If not, prove that there is a leak in the line or main pump. Take high concentration soap and washing powder water, with a brush on the trachea joint, air bubbles appear to prove the leak, tight or replace in time. Close to the main pump to hear whether there is a sound of air leakage or if there is a bubble in the residual air hole coated with soap and water. If there is a leak, check the main pump spring and seal ring. It is necessary to replace the exclusion. Step on the brake and listen to the main pump and each pump whether there is leakage sound.

(2) Keep the four-wheel pressure sufficient and equal before and after. The weight of the fire engine is mostly in the rear wheel, for this reason, the rear wheel is generally between 7Pa-8Pa, and the front wheel is generally between 5Pa-6Pa. The simple method is to use a hammer or iron rod to hit the tire elastic and shock is normal, on the contrary, the elasticity is not strong, the shock is weak for insufficient air pressure.

(3) Ensure adequate oil, water, electricity and gas. Oil is divided into two categories: one is vehicle oil; The second is oil, gear oil, hydraulic oil and so on.

2, regular maintenance.

Fire engines regularly carry out four-wheel maintenance, butter, oil and gear oil replacement.

(2) Whether the battery is charged, especially when the battery expires, pay attention to replacement

3, seasonal maintenance

The tropics are generally divided into two seasons (without freezing) : one is the rainy season; The second is the dry season. (1) The rainy season should maintain the brakes, especially the exclusion of unilateral brakes. The brake should be harder than usual and brake spirit.

(2) In the dry season, the brake water system should function perfectly, and pay attention to adding water when running far; The fan belt is tight.

4, initial drive maintenance.

(1) Ensure that all indicators are lit and functional.

(2) The alarm and the podium work normally, and the alarm light is on and turns and flashes.

(3) All kinds of instruments work normally.

(4) The pump keeps the butter sufficient.

(5) Check whether the screws of the whole system of the rotating shaft are loose.

(6) Sufficient oil, water, electricity and gas.

5, parking maintenance.

(1) When the fire engine is not moving, it should be often started to charge. Is the gasoline car to pull the appropriate throttle, see the charging meter to the positive charge is good. The principle is that each time the motor is used with battery power and the power is large, the speed of the gasoline car is generally not charged, the repeated play of the motor consumes the battery power and is not supplemented, the battery power is not supplemented repeatedly, and the power is insufficient to take the motor, and the need for high-speed trains cannot afford to send. It is appropriate to charge more than 10 points after each start.

(2) When the vehicle stops in place, see if there is oil dripping on the ground and there is oil on the ground. If it is necessary to check whether the screws are loose in the parts, the sealing gasket should be checked and removed if necessary.
