Our Senegal customers mainly transport liquid and oil.And he busniess a small oil company.He found us though alibaba that tell us he want to 3 axle gas tanker trailer with 5000L.
Here are some pictures of finished fuel tanker trailer.And we told his some knowledge of oil tanker trailer.It is can help his more easier to operate and grasp it.

The oil tanker has too little oil in the tank, and there is a lot of shaking space during transportation, which is easy to generate static electricity; if it is too much, it will easily cause overflow to the tanker with a poorly sealed tank. Therefore, the filling volume is about 85%. For appropriate. In addition, medium-speed driving should be maintained during transportation to ensure that the fuel in the tank of the tanker is relatively stable, and emergency braking should be minimized.
The so-called change of oil filling refers to, for example, the oil tank that was previously filled with gasoline, and now it is filled with kerosene or diesel or the opposite. Changing the filling of oil can easily form explosive mixtures in the tank, especially when the original gasoline in the tank of the tanker truck is now filled with kerosene or diesel.
The reason is that because both kerosene and diesel have the property of absorbing gasoline vapor, it will dilute the oil tank that has been filled with gasoline vapor and reach a rich state to the extent that it can explode, especially in winter. If static electricity occurs Flashover means that serious accidents such as fire and explosion may occur.

Therefore, when the fuel tank trailer changes the fuel, it is necessary to exhaust the deposited oil in the oil tank as much as possible, open the tank mouth of the oil tank, and let the oil remaining in the tank volatilize as much as possible. In addition, when filling the oil, the oil distributor should also be informed of the original oil in the tank so that the oil distributor can operate according to regulations, such as limiting the flow rate of the oil.
No water, impurities, etc. can be stored in the tank of the tanker truck, because the water in the fuel will significantly change the charging trend of the fuel, causing the voltage in the tank to increase dozens of times, or even hundreds of times, and it may also be in the form of sparks Discharge.
Impurities in the oil also have a greater impact on the generation of static electricity, especially some floating substances, such as wood chips, rubber, and isolated metal balls (the floating balls on the oil tank content scale of some tanker trucks fall off) are very dangerous.

The main reason is that this kind of conductivity has a capacitive effect and can collect and store more electrostatic charges. There is no fixed moving track in the tank of the tanker, and it is easy to approach the tank wall or other accessories in the tank of the tanker to form a proper discharge. gap. According to tests, once this phenomenon is formed, as long as the potential difference with the liquid level is 1-2KV, spark discharge may occur (normal liquid level is 28-30KV), and the discharge energy is strong, which can release all the stored energy at one time.
The valves on the fuel tank, the exhalation valve, the sealing ring of the fuel tank cover of the tanker, etc. should always be in good condition to prevent fuel leakage or overflow, and a fire can occur due to static electricity.
Before loading and unloading oil, the oil tanker and the oil loading and unloading equipment should be connected with electrostatic wires (the oil depot is equipped with electrostatic wires that are connected to the oil tanker).
1.It has the effect of accelerating the leakage of electric charge in the oil. Drain the static electricity induced by the oil tank to avoid flashover with external substances;
2.When connecting electrostatic wires, be sure to choose non-corroded and exposed metal parts on the tanker, and do not connect them to heavily rusted or painted places.
3.Keep the fuel tank trailer and the entire oil loading and unloading equipment at the same potential to prevent potential differences;
Data show that only when the resistance of the entire electrostatic grounding system is less than 10 ohms, can it achieve good electrostatic conductivity. The ideal way is to install a special copper connection board on a certain part of the tanker truck for connecting electrostatic wires.

In addition, the electrostatic grounding wire on the gas tanker trailer cannot be used as the electrostatic wire for loading and unloading oil. The reason is that the tank truck is generally parked on concrete or hard ground during loading and unloading. The resistance of the electrostatic grounding wire is not It may be less than 10 ohms. Therefore, it is difficult to ensure that the oil loading and unloading equipment maintains equipotentiality.
The anti-static facilities on the tank truck are mainly the static grounding wire and the oil separator in the tank. There are two types of electrostatic grounding wires: chain type and conductive rubber belt. The former is prone to sparks due to ground impact, time lapse when grounding, and easy to rust will increase the leakage resistance and other shortcomings. Now new 3 Axle fuel tanker use rubber grounding straps.
Therefore, the static grounding wire should be adjusted frequently to ensure that it has good contact with the ground and a multimeter should be used to check whether it is unblocked and broken, and replace it in time if there is a problem. The function of the oil separator is to reduce the shaking and splashing of the oil in the tank during the transportation of the tanker, so as to reduce the generation of static electricity. If the grease trap is removed from the maintenance oil tank, it must be installed in time. It must not be regarded as an optional device.
(1) Pay attention to the accumulation of static electricity
The amount of oil in the oil tank should be appropriate: too little oil in the oil tank, large shaking space during transportation, easy to generate static electricity; too much, it is easy to cause overflow to the car with a poorly sealed oil tank mouth, so the filling volume is 85 About% is suitable. In addition, the medium speed should be maintained during transportation to ensure that the fuel in the tank is relatively stable, and emergency braking should be minimized. It is necessary to connect the static wire to ensure that the static wire is in contact with the ground.

(2) It is strictly forbidden to drive the tanker truck when fatigued
When driving a vehicle in a warm cabin, the air circulation is poor, the driver is prone to fatigue; often feel mentally tired, vision gradually becomes blurred, thinking becomes dull, especially in the afternoon or midnight driving is easy to fall asleep, reluctant driving will cause traffic accidents occur. Avoid fatigue driving and ensure driving safety.
(3) Stay away from fire
When driving a fuel tanker, smoking, answering and calling mobile phones are not allowed, and you must stay away from the tinder when parking, and not park on the edge of the tinder, causing an explosion.
