Tanker composition and introduction, related understanding
â— Â Tanker
Tanker trucks are also known as mobile refueling vehicles, computer tax-controlled refuelling vehicles, oil tankers, loading vehicles, oil tankers, oil tankers, oil tankers, edible oil transporters, and are mainly used as derivatives of petroleum (gasoline, diesel). (oil, crude oil, lubricating oil, coal tar, etc.) Transportation and storage. According to different use and use environment, there are many kinds of refueling or transporting oil functions, which have the functions of oil absorption, pump oil, multiple oil loading and distribution.
Tanker special function description
Tank material: carbon steel, stainless steel, aluminum alloy, pure aluminum can, rubber lined, rotomolded, plastic tank, fiberglass tank can also be used as required.
Can type: round, oval, round
Oil pumps: self-priming pumps, gear pumps, chemical pumps, stainless steel pumps, centrifugal pumps, heavy oil pumps. Oil gauges: single-count, double-count, tax-controlled fuel dispensers.
Tanker breathing valve:
In order to ensure that the tanker is in operation, the pressure in the tank is basically the same as the atmospheric pressure. A breathing valve is installed on the tank and the oil level in the tank rises when the oil in the tank is heated to expand or when the oil is pumped into the tank. The pressure increases, when the tank pressure is higher than the external pressure 8KPA, the valve on the breathing valve opens; When the oil pump to the outside or the oil cold shrinks when the oil surface drops, the pressure decreases, when the tank pressure is lower than the outside pressure At 3 KPA, the valve below the breathing valve opens.
Function: Can separate positions, can be divided into different oil products, chemicals, food. Designed to achieve pumping, pumping out of the table, the pump into the pump but the table, self-flow over the table, but the table and other functions.
 Tanker tank structure
The tanker truck is composed of a special vehicle chassis and a top-loading part. The top-loading part is composed of a tank body, a power take-off device, a transmission shaft, a gear oil pump, a pipe network system and other components. The pipe network system consists of oil pumps, three-way four-position ball valves, two-way ball valves, strainers and pipes.
The tank structure is an elliptical cylindrical or trapezoidal surface cylindrical body, made of high-quality steel plate, the entire tank is divided into single or multiple positions, the chamber can be divided into chambers, the bottom of the intermediate baffle has through holes, and the intermediate positions of each warehouse are welded or Multiple warehouses, warehouses can be divided into rooms, through the middle of the bottom of the baffle through holes, each warehouse is welded with a warehouse to strengthen the wave baffle, in order to reduce the impact of the oil in the tank body and improve the rigidity of the tank body.
Car fire shield
Automotive fire protection cover (also known as motor vehicle exhaust spark extinguisher, automobile exhaust pipe fire protection cover, spark extinguisher, Mars extinguisher, fire protection cover, fire protection cap, automobile fire protection cover, automobile flame arrester, automobile fire protection cap, fire protection cap) It is a kind of safety fire prevention and fire prevention device that is installed in the exhaust pipe of the motor vehicle and allows the exhaust gas to pass through, and prevents the flame and the spark from blowing in the exhaust gas flow. It is an important safety and fire protection product that must be equipped with certain national fire protection units and all transportation vehicles in certain areas. It is applicable to key fire prevention units and warehouses, warehouses, oil fields, forest areas, coal mines, petrochemical liquefied gas plants, paper mills, and airports. The installation of the product is very convenient and quick. Only one end of the opening with clamping collar of the caliber matching specification product is placed on the exhaust pipe of the corresponding motor vehicle, and then the nuts on both sides of the clamping collar can be tightened.
â— Tanker user operation guide
1. To ensure the tank truck is clean, the tank and oil system should be cleaned periodically. The inner and outer joints at both ends of the oil hose should be coated with lubricating oil. The tank truck can be easily disassembled and installed. After each time the tubing is completed, clean it in time to ensure that it is clean inside!
2. The use and maintenance of the tanker oil pump is strictly performed according to its use and maintenance instructions! 3, before refueling operations, must use the plug to insert moisture into the wet land, the tanker grounding tape should be grounded, the operation process should always maintain good static conduction! 4. Tanker safety valves and filter nets should always be checked and cleaned! 5, tanks and piping systems should be cleaned regularly. The tanker regularly checks whether the joints of the pipeline system are well connected and the seal is reliable! 6: The tanker should be installed according to the specification electrostatic belt, when the static electricity encounters the flammable gas with extremely high concentration remaining in the car, the harm occurs. The static electricity belt has frequent friction for the car body and the like, and the space where static electricity is easily generated can effectively go out Electrostatic hazards to ensure that the body is not compromised.installation method:
Installed in the chassis metal parts! After a period of wear, the rubber band on the top can be put down!
Conditional users can install electrostatic tanker grounding alarm
7. Tanker trucks should be equipped with special fire extinguishers and should be equipped with tow subway chains and electric poles. When driving, the tow subway chain should be in contact with the ground; when refueling or draining, it must be inserted into the damp ground.
8. The oil tank filling hole should be tightly sealed, the oil discharge valve and the oil discharge pipe should be free of leakage, the tank vent hole should be unimpeded, the oil pump oil inlet filter should be cleaned frequently, and the two ends of the joint cover should be installed immediately after the delivery oil hose is used up. No dirt can enter.
9. Gasifiers and exhaust pipes of internal combustion engines must not be tempered. The exhaust pipe should be installed in front of the vehicle.
10. Tanker workers must not wear nailed shoes. It is forbidden to smoke near the oil tank and fire is strictly prohibited.
11. When parking, you should stay away from the fire source. During the hot season, you should choose a cool place to park. During a thunderstorm, it must not be parked under trees or under high-voltage lines. When parking in the middle of driving, there should be special care.
12. During the inspection and repair process, if the operator needs to enter the oil tank, it is strictly prohibited to carry the fire, and must have reliable safety protection measures. The outside of the tank must have special personnel to monitor.
13. All electrical devices in the vehicle must be well insulated and no sparks are allowed. Vehicle work lighting should be a safety light of 36V or less.
14. When the tank sedimentation tank is frozen, it is forbidden to use fire to bake, and it may be used to melt hot water, steam, or thaw the car into the greenhouse.
15. When carrying out maintenance and inspections under the vehicle, the internal combustion Engine should be turned off, the hand brake should be tightened, and the wheels should be secured.
16. When a vehicle needs repair after repair, it should be driven by a qualified person. The vehicle must not be loaded with people and carry loads. When a vehicle needs to be tested on the road, a test license issued by the traffic management department should be affixed.
17. When parking on a ramp, a reverse gear should be hung on a downhill parking, a gear should be hung on an uphill parking, and a triangle wooden wedge should be used to fasten the tire.
â— Fire tank precautions
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. When maintaining the fuel filter, it is not advisable to use gasoline to filter the filter element. 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 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, are not allowed to use the method of hanging fire. 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. Do not allow leaks 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.
