1. Function, classification and production process description of oil tanker.

Oil tanker refers to a special vehicle equipped with a tank container for transporting oil, mainly used for the transportation and storage of gasoline, diesel, crude oil, lubricating oil, coal tar, edible oil and other liquid chemicals. Gear oil pump can be installed on the car, through the main car engine to take force, to achieve the function of pumping in and pumping out, can be divided into silos to achieve a variety of oil distribution, distribution and other functions. The refueling vehicle is composed of force extractor, drive shaft, gear oil pump, tank and pipe network system. The pipe network system is composed of oil pump, three-way four-way ball valve, two-way ball valve, filter screen and pipeline. In addition, the refueling truck can be installed with truck-mounted refueling machine, which can realize the measurement of refueling by liter or by amount. The flow meter can be optional, equipped with refueling reel and refueling gun, and become a mobile refueling truck - "mobile gas station".

Fuel truck according to user requirements, can be installed gear pump, centrifugal pump, heavy oil pump, stainless steel pump, can be installed heating pipe, insulation layer. Tank body has half round tank, square tank.

Classification of tank cars

According to the size of the tank, the tank truck is divided into: small tank truck, medium tank truck, large tank truck, semi-trailer tank truck;

According to the type of chassis, tank cars are divided into Dongfeng tank cars Liberation tank cars Foton Auman tank cars Foton Times tank cars Foton Aoling tank cars Jiangling tank cars Jianghuai tank cars Shaanxi gasoline tank cars heavy truck tank cars.

Tank car buying guide

1 Different chassis, the price is different because the car chassis ****** and configuration are different, so the price is different;

2 parts are different, the price is different because the use of auto parts is different, making the price different;

3. Different materials and prices The types of materials used in different tanks and the amount of materials used make the prices different;

Can making instructions

1. The tank body is made of 4mm or 5mm high-quality carbon steel sheet, which is manufactured by butt welding process according to the national production standards of oil tank trucks. The shape can be oval or square.

2, the tank body is equipped with a multi-channel anti-wave partition. The high pressure gas leakage test is adopted to make the tank with high strength, stable center of gravity, safe and stable for vehicle transportation.

3, all kinds of alcohol, sulfuric acid, hydrochloric acid, salty liquefacient tank truck imported from South Korea stainless steel (thickness of 4mm-5mm) or plastic tank (polypropylene) (thickness of 12mm-22mm) manufacturing.

Second, the precautions when driving the tanker

First of all, the station requires that the oil pulling vehicle and driver must hold the dangerous goods pulling license and the inflammable and explosive training certificate, and only the tanker driver and the oil loader are allowed to enter the loading area. The entering vehicle must wear a fireproof cap and make a basic network for entering the station.

Secondly, it re-improved the regulations on the management of light oil loading, strictly and carefully stipulated the preparation work before loading and the precautions during loading, and required Party A to master the car pressing personnel in the form of an examination paper, so as to create a network of operation specifications.

In addition, for the maintenance of inflammable and explosive tanks, the tank should be washed first, and after washing, it is best to use steam to steam the high-temperature steam inside the tank to let the gasoline in the tank completely evaporate before welding and other operations to prevent the occurrence of accidents such as explosions;

Three, the common fault classification of oil tanker

The fault of the ignition system can be divided into two cases according to its position in the ignition system: the low-voltage circuit fault of the tank car and the high-voltage circuit fault.

(1) Common faults of low voltage circuit of tank car:

Insufficient storage of battery; Poor or disordered wire connections; The battery is not built properly; Distributor or hall sensor damage; The ignition switch is damaged or poorly connected; Transistor ignition control unit damaged or poorly wired. The diagnosis methods of low voltage circuit fault of tank car mostly use ammeter or voltmeter line-by-line inspection to eliminate the fault point.

(2) Common faults of high-voltage circuit of tank truck:

The high voltage line of the tank car falls off or leaks electricity; Breakdown of distributor cover; Distributor head ablation rupture breakdown; The spark plug electrode gap is too large or too small; Excessive carbon accumulation in spark plug; Spark plug insulator damaged; The ignition coil is damaged or the cable is disconnected. The fault of the high-voltage circuit mostly adopts the high-voltage fire test method, that is, the distributor center high-voltage wire or a cylinder high-voltage wire is removed, the wire end is placed 3-6mm away from the cylinder block, start the engine fire test, there is a spark and the spark is strong, indicating that the ignition system is working normally.

2. Tank car ignition system does not work

(1) Fault phenomenon: open the ignition switch, start the engine, the engine does not respond; High voltage fire test, high voltage wire no spark.

(2) Fault analysis and diagnosis

3. The ignition time of the tank car is too early

(1) Fault phenomenon: idling operation is not smooth, easy to stall; When accelerating, the engine made a serious deflagging sound.

(2) Fault analysis: The fault is mainly caused by misalignment of ignition timing adjustment or misalignment of ignition Angle assembly.

(3) Elimination method: Connect the ignition tester and adjust the ignition advance Angle to the specified value.

4. The tank car fires too late

(1) Fault phenomenon: muffler sound heavy, rapid acceleration carburetor tempering, engine coolant temperature is high, the car is weak.

(2) Fault analysis and diagnosis: the ignition Angle is incorrect.

(3) Exclusion method: Adjust the ignition Angle to the specified value.

5. The spark plug of the oil tanker is faulty

The main manifestations of the fault are: spark plug carbon accumulation, oil pollution and overheating

Spark plug overheating: the central electrode is melted, the top of the insulator is loose and soft, and the end of the insulator is mostly gray and white.

Spark plug carbon deposit: The end of the insulator, the electrode and the spark plug shell are often covered with a rather thick layer of black gray powdery soft dirt.

Spark plug oil: Fault phenomenon: insulator end, electrode and spark plug shell covered with a layer of oil.

6. Tank truck engine knocking and overheating

The tank car engine is prone to knock at high load and medium speed. In the case of using the correct fuel grade, the knock phenomenon is mostly caused by excessive ignition advance Angle. In the case of detonation, the engine heats up rapidly. On the other hand, the ignition advance Angle is too backward, the ignition is too late, and the engine temperature of the tank car will be high. In the absence of detonation, most of the high water temperature is not caused by the ignition system, but if the engine is weak and the acceleration is not sensitive, the ignition advance Angle should be checked whether it is too small.

Four, the rescue method after the fire of the oil tanker

Tank car fires include rail tank cars and automobile tank cars. The fire at the opening of the tank car is usually caused by the ignition source of oil and gas, such as iron collision, static electricity and lightning. The fire at the orifice of the tank truck generally forms a stable combustion, the flame is torch-like, and the flame temperature is high, which poses a great threat to the loading and unloading of the oil crane pipe, the trestle and the tank car itself.

1. Isolation fire extinguishing method. Isolation fire can be extinguished by water flow closure, water spray, covering and other methods, in which asbestos is used to cover the mouth of the tank, or the manhole cover of the tank truck is closed, so that the oil and gas and air are isolated and the flame is more convenient and effective.

2. Use fire extinguishers to put out fires. Most of the oil handling sites are prepared with dry powder fire extinguishers, which can be used to spray into the manhole to extinguish the flame. In the early stage of fire, this method has the best effect.

3. Dc water gun extinguishing. When the fire time is longer, the flame is larger, and the fire extinguishing personnel can not get close to it, it is advisable to use several DC water guns to form a water curtain and isolate the air to extinguish the fire. The foam hook pipe can also be hung in the manhole of the oil tank to spray foam into the tank to extinguish the fire.

4. Matters needing attention

In case of a fire, the emergency valve should usually be closed, the oil loading and unloading operation should be stopped, the oil source should be cut off, and the oil loading and unloading pipe should be taken out from the tank car. Generally, the unburned oil tanker should be evacuated to a safe area, and the fuel around it should be evacuated timely according to the specific situation. When conditions permit, the burning oil tank can also be evacuated to a safe area to extinguish the fire. After the oil tanker fire, cooling measures should be taken as soon as possible to protect the oil tanker, crane pipe, trestle and surrounding buildings to prevent the expansion of the fire.
