Semi-trailer tanker

The semi-trailer tanker is divided into two parts, the tank part and the frame or supporting part of the support tank.

The semi-trailer tanker is a tanker truck that uses a traction head to connect the towing part. Compared with the ordinary single-unit tanker, semi-trailer tanker can effectively improve the transportation efficiency. In the same tonnage, reduce transportation costs and save fuel consumption.

The rear part of the semi-trailer tanker truck is roughly the same, with the rear double bridge (two axles) and the rear three axle (three axles), and the traction head is selected as required. According to the brand of the traction head, semi-trailer tankers are often referred to as: Dongfeng semi-trailer tanker, liberation semi-trailer tanker, Auman semi-trailer tanker, etc.

1. The tank body is made of 4mm or 6mm high-quality carbon steel manufactured by Wuhan Iron and Steel Co., Ltd. and manufactured according to national standards. The shape is elliptical or square circular tank, which can hold 1-4 kinds of oil products. Can also produce heat insulation series tanks.

2, alcohol, chemical tanker made of stainless steel imported from South Korea, thickness 4mm-5mm.

3, all kinds of hydrochloric acid, sulfuric acid, alkaline tanker made of plastic, thickness of 12mm - 22mm.

4. Multiple anti-wave separators are installed in the tank body. The use of high-pressure gas leak detection, so that the tank has high strength, stable center of gravity, vehicle safety and stability.

5. Centrifugal pump, gear pump and stainless steel pump can be used according to the purpose of the tank car. It has the characteristics of large flow rate, fast suction speed and so on.

6. The metering of tank trucks can use single counting, double counting flow meter, and can also be equipped with tax-controlled computer fueling machine, install 10-15 meters automatic telescopic rewinding reel, equipped with refueling gun. The edible oil products can be measured by using an edible oil computer meter.

(1) Do not pour petrol into the carburetor port while the engine is running or when it is cranking. The carburetor is filled with gasoline to increase the concentration of the air-fuel mixture in the cylinder. Although this will be beneficial if the oil fails to enter the cylinder, it is of no avail to the other causes of the failure, and this may also cause Fire, burns and burned vehicles and other hazards.

(2) Gasoline filter cartridges are not advocated when maintaining gasoline filters. Many people like to use gas-fired ceramic filters to remove impurities from filter elements when they are maintaining gasoline filters. The hazard of doing so is easy to misfire, at the same time have an impact on the life of the filter element.

(3) In the oil depot, it is not allowed to check the storage condition of the battery by means of short circuiting. Because in poorly ventilated small oil depots, equipment such as tires, batteries, and tarpaulins are often placed on the ground. Spilled gasoline is on the ground. Sparks generated during fire fighting are likely to ignite the oil molecules in the air.

(4) The drag chain of the tanker truck must not be wrapped around the girder. Oil, like other substances, also generates static electricity when rubbed against another object. This kind of electrostatic flashover may ignite the fuel and cause a fire. Therefore, a grounded ground wire should be installed on the oil depot, and a grounded iron chain should be installed on the tanker to prevent static sparks in the tank. This chain cannot be wound on the frame of the beam and must be placed on the frame. On the ground, and drag the lot no less than 50 centimeters.

(5) It is forbidden to add fuel under the high voltage wires.

(6) The method of hanging fire is not often used. Sometimes the spark plug of a car will have carbon deposition. When a certain cylinder's carbon deposition is serious, the cylinder will not work properly. In order to make the cylinder work normally, the method of “hanging fire” outside the cylinder is adopted (leaving the spark plug and the high voltage wire 3 Mm - 4 mm gap) to improve the energy of the spark plug electrode flashover, so that the cylinder back to work, but the general "hanging fire" method is not easy to fall off with little attention. If there is dripping gasoline on the cylinder, it is extremely easy to have a fire. Therefore it is only a temporary remedy. The correct treatment should be timely cleaning and maintenance of spark plugs, try to avoid the use of "hanging fire" method.

(7) No leakage is allowed in the automotive oil system. If the chassis part of the oil circuit is leaking, and it is on the ignition late, mixed gas lean point, due to slow combustion will lead to exhaust pipe fire, the body temperature increased, more than ten times the ignition point of gasoline vapor (gasoline vapor The ignition point is 28°C). Leaking out the oil can easily cause a fire and cause the vehicle to be scrapped. If the carburetor part drips on the cylinder head, spark plug high voltage spark leakage may also cause fire.

Some people think that the maintenance of oil tankers is changing oil. This is one-sided and wrong. Maintenance of tank trucks is a broad concept, including oil and filter replacement and cleaning of various engine systems (oil, gear oil, brake oil, auto-oil, booster oil, glass water, battery water, machine filter, steam Filter, air filter, air conditioning filter, etc.) Replacement and maintenance of consumables of oil tankers such as belts, spark plugs, batteries, brake pads, ball heads, clutch plates, shock absorbers, etc., tank car beauty (car wash, exterior paint Nursing, interior trimming care, etc.).

Normal tanker maintenance can maintain vehicle performance and extend its useful life. The introduction of the maintenance of consumables of oil tankers this time is how to inspect, replace and maintain. At the same time, the phenomenon of wearable parts found in the maintenance and these phenomena indicate what the problem is.

Spark plugs typically have a service life of 15,000 km and long-acting spark plugs have a service life of 30,000 km. The function of the spark plug is to introduce the high voltage pulse generated by the ignition coil into the combustion chamber, and use the spark generated by the electrode to ignite the mixture to complete the combustion.

Domestic spark plug models consist of three numbers or letters. The preceding number indicates the thread diameter, such as the number 1, which means that the thread diameter is 10mm, the middle letter indicates the length of the spark plug screwed into the cylinder part; the last digit indicates the thermal type of the spark plug: 1-3 is hot type, 5, 6 is Medium, 7 or more cold. The "gap" of the spark plug is its main working technical index. The gap is too large, the high voltage generated by the ignition coil and the distributor is difficult to skip, which makes the engine start difficult. If the gap is too small, it will cause the spark to be weak, and it is prone to leakage.

There are two kinds of common failures of spark plugs: Severe ablation of the spark plug, smashing of the top of the spark plug, destruction of the spark plug, or melting of the electrodes and ablation all indicate that the spark plug has been destroyed and should be replaced. Spark plugs have deposits. The top of the spark plug insulators and the electrodes are sometimes stuck with deposits. In severe cases, the engine will not work. For example, cleaning spark plugs can be temporarily remedied, but the root cause of the fault must be identified.

â—† The driver's friends should pay attention when the tanker is driving:

1 The tanker checks the working condition of each instrument while driving;

2 Check if the steering system is working properly when the tanker is in motion;

3 It is abnormal for the tanker to check the hand and foot brake while driving.

4 The tanker checks whether the engine, the chassis and the tank body are abnormal noises and abnormal odors during running.

5 Use the parking time to do the following inspections of the tanker: Check whether the brake drums of the front and rear wheels are overheated, check the tightening of the tires and nuts, remove the inclusions in the tire tread, and check for oil leakage or water leakage. , leak, check the situation of the leaf spring, if the drive shaft bolts are loose, check the appearance of the tank body and the tank network system of the tanker.

[1] First: The longer the car, the more lazy the maintenance

When a new car is used, the frequency of maintenance is very high, and a little problem will run 4S shop. The car is available for a long time, and it pays less and less attention to vehicle maintenance. Mr. Ying is one of the extreme examples. In fact, the frequency of car maintenance should be proportional to the age of the car. The longer the car is used and the greater the mileage, the more frequent maintenance should be. For example, a new car will be maintained once every 10,000 kilometers, and a 10-year old car should be maintained once every 1,000 kilometers. Nowadays, old cars that have been stipulated for more than six years are subject to annual inspections. This is the reason.

Second: The steering wheel is hit in the end

In the course of learning the car, the coach sometimes allows the trainee to “touch the steering wheel”, which is to make the car go more accurately. However, after schooling, many owners still retain this habit, and even intensify and fiercely beat the direction, this habit is very hurt, because doing so will make the steering system of the ball head, connecting rod wear is greatly increased. In addition, for the assisted steering vehicle, when the steering wheel is killed, the output of the booster pump to the steering gear is maximized, which causes the internal hydraulic pressure and the oil temperature of the booster system to increase rapidly, which may easily lead to damage or leakage of the assist system.

Third: brakes in the end

Bombing the throttle, slamming on the brakes is what many people like to drive. At present, cars mainly use disc brakes and drum brakes. Disc brakes use brake pads and brake discs to produce brake energy, and brake pads are lost parts. Pushing the brakes often will greatly shorten the life of the brake pads. Some cars can replace brake pads for 40,000 kilometers, and some cars will have to be replaced when they are 10,000 kilometers away. However, if the brake drum is often slammed on the brake, it can easily cause the brake to overheat and fail, which will affect the safety. Therefore, slamming on the brakes is the last resort to be done. Usually, driving should be based on “point brakes”.

Fourth: "Road to meet uneven" fuel door

Many people drive quickly and swiftly, and they do not slow down when they go over the deceleration belt or the gully. Encountered the pit road section, but also increase the throttle speed. These habits can easily affect the wheel alignment system, leading to vehicle deviation, or affecting the tire's life, and affecting the vehicle's suspension. Sometimes the trench can scratch the vehicle's chassis and even hit the engine.

Fifth: Randomly get on and off the road

This is the "killer" of car tires. Hantai Tire has done statistics. In China, 70% of tire damage is caused by cars getting on and off the road. In particular, squeezing on the side of the road can easily cause the tire to break. In addition, when the units and the district could not find a parking space, many car owners would use the flower beds and roadsides to park the car diagonally for a whole day. As everyone knows, this type of parking will make the tire steam pressure unbalanced for a long time, and it is very easy to cause tire bulging.

Sixth: Gasoline Alarm Continues to Drive

If the fuel tank warning light is on, it means that there are few left in the tank. But the old driver knows that, with the remaining fuel, the average vehicle can still travel tens of kilometers. However, many models of petrol pumps are currently installed directly at the bottom of the fuel tank. Gasoline pumps rely on gasoline for lubrication and cooling. If the amount of gasoline is missing too much, the gasoline pump cannot be properly lubricated and cooled under driving conditions, which can easily cause damage to the pump body.
