What Is a Tanker Truck Driver?

A mobile fuel truck, a type of tanker truck. It is based on a fuel tanker and is equipped with major components such as a refueling machine, automatic reel, refueling gun, and pump. It is mainly used as a derivative of petroleum (gasoline, diesel, crude oil, lubrication Oil and coal tar). According to different purposes and use environment, there are a variety of oil filling or oil transport functions, with oil absorption, pump oil, a variety of oil distribution, distribution and other functions.

Design the function of the fuel tanker according to the main purpose of the mobile fuel tanker. Fuel tank trucks equipped with standard fuel tank manufacturers can achieve independent sub-storage, which can be used for different oil and chemical products. The pump can be designed to pump in and out of the meter. The tank body is made of carbon steel, stainless steel, lining rotomolded, and glass steel. Pot shapes are square, oval, and round. The oil pump uses a self-priming pump and a gear pump. The oil meter uses single-count, double-count, tax-controlled refueling machines. Optional water tanks, European standard cans, subsea valves, etc.

Advantages of mobile fuel truck

1. For large vehicles, the choice of fueling by mobile refueling vehicles can reduce fuel consumption costs and save man-hours. Most heavy machinery is used in mountainous areas or in the wilderness. There are few gas stations around and the roads are rugged. When the car s fuel is burned out, driving to a gas station to fill up gas is time consuming and fuel consuming. These problems can be avoided if the mobile fuel truck is used to deliver fuel. An experienced driver will call the fuel supplier when the fuel is used up, and the fuel supplier will send a mobile fuel truck to refuel. Although the gas price of these mobile fuel trucks will be higher than the gas price of gas stations, considering the fuel consumption of driving by themselves and the delay of engineering hours, it is still very cost-effective to use mobile fuel trucks to supply fuel.

2. Mobile fuel trucks have less investment and get rich faster. The price of an ordinary 3-5 ton mobile fuel truck is 70,000 yuan, including 100,000 yuan for all the expenses such as listing and insurance, which can be afforded by most families. Nowadays, whether it is a commercial vehicle or a family car, the demand for oil is greater than the supply, so there is no case that oil cannot be sold. Investors only need to find stable and cheap oil suppliers, and contact stable oil demand projects or objects, and they can make money every day. Take a 5-ton oil truck as an example. The fuel capacity of a full tank reaches 6,000 liters. The net profit of each liter of oil makes a difference of 0.2-0.3 yuan, and that one car of oil can earn 1200-1800 yuan. For engineering, the daily oil demand exceeds 6,000 liters.

3. One of the reasons why mobile fuel trucks make money is because of inadequate state management. The full name of the tanker mounted on the mobile fuel truck is called a computer tax-controlled tanker. The country's original idea was to use it to collect certain taxes and fees. However, because the management system could not keep up, the tax department did not charge them any taxes. This has resulted in a high rate of return on such vehicles.

Precautions for use of the tanker:

1. When supplying power to the tanker, ensure that the voltage is in the range of DC10V ~ DC30V, so as not to damage the computer components during the peak voltage.

2. Since the pump supplying oil to the tanker is self-supplied by the car, in order to ensure the pressure stability, the pipeline of the car should be equipped with a relief valve. If not, it should be specified at the time of ordering. Tanker.

3. When using an oil gun (automatic return reel of the dispenser), avoid using the oil injection pipe of the oil gun to strike the receiving container, press the switch and other incorrect operations. This operation may damage the root of the oil injection pipe and cause oil leakage. To check regularly, tighten the stop screw on the oil injection pipe to prevent the root of the oil injection pipe from loosening and damaging.

4. The oil tank should be cleaned regularly to keep the oil clean.

5. A filter is installed in front of the oil inlet of the dispenser. Due to the different oil conditions in different places, the replacement cycle of the filter cannot be clearly specified. When the flow of the dispenser is suddenly reduced, please replace the filter. The flow is still abnormal. Please check whether other components affect the flow. If it affects the flow, replace it in time.

Analysis of fault resolution of ignition system ^[1]

1.Do not check the plunger stroke margin

In the irony of the plunger fuel injection pump, many maintenance personnel did not pay attention to check the plunger stroke margin. The stroke allowance of the plunger refers to the amount of movement that the plunger can continue to move upward after being pushed by the cam on the camshaft to the top dead center. After adjusting the oil supply start time, the reason for checking the stroke margin is because the stroke margin of the plunger is related to the wear of the plunger and the sleeve. After the plunger and the sleeve are worn, the plunger needs to move up a little more to start the oil supply, which delays the start of the oil supply. When the adjustment bolt is unscrewed or a thicker adjustment block or washer is used, the lowest position of the plunger is moved up, so that the stroke allowance of the plunger is reduced. Therefore, when repairing and debugging the fuel injection pump, the stroke margin should be checked first to determine whether the fuel injection pump can still be adjusted. During the inspection, the following different methods should be adopted according to the different structures of the fuel injection pump: a) After turning the camshaft, pushing the plunger to the top dead center, remove the oil outlet valve and valve seat, and measure with a depth vernier. b) After the plunger is pushed to the top dead center, use a screwdriver to pry up the spring seat of the plunger spring to raise the plunger to the highest point. Then use a thick gauge to measure between the lower plane of the plunger and the tappet adjustment bolt. The standard stroke allowance of the plunger is about 1.5mm, and the limit stroke allowance after wear should not be less than 0.5mm.

2. Avoid installing new cylinder liners and pistons without optional equipment.

When replacing cylinder liners and pistons, the new cylinder liners and pistons are considered standard parts and are interchangeable, so they can be used after being installed. In fact, the dimensions of the cylinder liner and the piston have a certain tolerance range. For example, if the largest size cylinder sleeve is fitted with the smallest size piston, the fit clearance will be too large, resulting in weak compression and difficulty in starting. Therefore, the size group code of the standard cylinder liner and piston must be checked during the replacement. The size group code of the standard piston and the piston must be the same as the size group code of the standard cylinder liner. Only in this way can the two be guaranteed. With standard fit clearance.

3. Avoid measuring cylinder gap

When measuring the cylinder clearance, the piston skirt was not measured in a direction perpendicular to the piston pin hole, and was measured in other directions. The structural characteristics of the aluminum alloy piston are that the upper part is smaller, the lower part is larger, and it is a cone, and the partial cross section is oval, so the cylinder clearances along the circumferential direction are not equal. During the measurement, the clearance in the direction of the major axis of the ellipse shall prevail, that is, the clearance between the piston skirt and the direction of the piston pin hole shall be measured. This measurement is more convenient and accurate, and in the reciprocating motion, the direction of the piston skirt perpendicular to the piston pin hole is subject to greater wear due to the lateral pressure. Therefore, when measuring the cylinder clearance, the piston skirt should be perpendicular to the piston. Measure the direction of the pin hole.

Maintenance of fuel truck

1. The use and maintenance of automobile chassis and engine parts shall be carried out according to the instruction manual of the truck.

2. The use and maintenance of the oil pump shall be strictly performed in accordance with its operation and maintenance instructions.

3. The use and maintenance of the tanker should be performed in accordance with its instruction manual.

4. The filter screen should be removed and washed frequently.

5. The oil tank and piping system should be cleaned regularly.

6. The safety valve should be checked and cleaned frequently.

7. Regularly check whether the joints of the pipeline system are well connected and sealed.

8. After each work, the ball valve handle should be turned to the closed state.

9. The ball valve should not be in a half-open state to avoid damaging the seal seat.

10. After each work is completed, the inlet and outlet end caps (clogging caps) and the ends of the oil delivery hose (clogging caps) should be covered in time.

11. The oil loading should not exceed the rated loading mass. (Converted according to oil density).

12. Take off the power box before driving.

13. Before operation of the fuel truck, the conductive rod must be inserted into the wet ground. The grounding chain should be grounded, and the static electricity should be kept good during the operation.

14. When the fuel truck is running, it must be connected to the ground.

15. Before operation of the fuel truck, check whether the pipeline system is leaking oil, whether the ground wire is disconnected, and whether the exhaust pipe is damaged. If problems are found, the problem should be solved before operating.

16. It is not allowed to knock on the parts of the fuel truck with metal objects to avoid the occurrence of Mars. During operation, care should be taken not to cause Mars, and the fuel measurement should be performed in accordance with relevant regulations.

17. This vehicle is equipped with two fire extinguishers. Fuel tank users should be familiar with the use of fire extinguishers and inspect and maintain them according to their instructions.

18. When it is necessary to work in the oil tank, it should be well ventilated and there must be someone outside the tank to protect it.

In October 2019, reporters conducted unannounced investigations in Jiangsu and other places and found that highways, logistics parks, hospitals, and residential areas were flooded with illegal refueling points or mobile refueling vehicles for illegal operations. Many civilian police report that illegal refueling operations have shown new trends such as tricky refurbishment, rampant rebound, and stealth mutation, posing a threat to comprehensive security such as taxation and the environment. ^[2]

According to public security organs and other departments, in recent years, self-flowing black refined oil sales sites such as self-contained tanks, mobile fuel trucks, and black refueling stations have been repeatedly hit, and some illegal elements such as Four Entering the Palace have continued to teach. Grass-roots cadres believe that due to the high profits of illegal retail, insufficient legal penalties, lack of cooperation between competent authorities and insufficient market supply, underground diesel and gasoline transactions have continued, and it is suggested that blocking and dredging should be combined to crack down on the predicament. ^[2]

A section of National Highway 310 in northern Jiangsu is a logistics distribution center, and many trucks are parked and replenished. The "Economic Reference" reporter saw that there were two mobile gas trucks parked across the road from regular gas stations. Under the banner of selling diesel, they privately sold car owners in bulk gasoline. According to many refueling drivers, in this area, there are more illegal refueling points than regular stations. ^[2]

Driven by huge profits, the illegal operation of refined oil products has been repeatedly banned. The reporter found out that similar cases have occurred in Jiangsu, Shandong, Zhejiang, Anhui, Hubei and other parts of the country, and tragedies occurred in many places. The operation of illegal diesel fuel has become a huge black industry chain. ^[2]

An "Economic Reference" reporter visited the Shahe section of the 310 National Highway in Ganyu District, Lianyungang, and found that many staff members of private gas stations stated that they could only issue receipts. A worker confessed that there was a spread because "no invoice was issued." Staff at Sinopec Lianyungang Branch said that some private retail oil prices are 1 to 2 yuan lower per liter than regular prices. If this price is used, regular gas stations will lose about 5 million yuan per year. ^[2]

A manager of Sinopec's Jiangsu Lianyungang Branch revealed that many illegal operating units took oil from local refineries and evaded the ticketing of non-taxable products such as "asphalt" and "light hydrocarbons." According to the police handling the case, in the past three years, Shandong s underground diesel gasoline that flowed into Xuzhou averaged about 250,000 to 300,000 tons, and the state tax alone in Xuzhou alone has reduced more than 760 million yuan each year. Wang Bo, director of the Financial Assets Division of Sinopec's Jiangsu Petroleum Branch, said that escape tickets are rampant, and the country loses huge consumption taxes every year. ^[2]

From May 2017 to February 2019, the police station of the fourth team town of Guanyun County Public Security Bureau in Lianyungang repeatedly found that the oil seller Chen Moumou illegally stored and sold gasoline. ^[2]
