Safe configuration of fuel tanker trailers

Have you ever wondered why tanker trailers are so common on the road but rarely cause accidents? That's because of a series of technologies and configurations that can prevent leaks and potentially even bigger disasters.

What makes a tank trailer safer?Or what configuration should I pay attention to when buying a fuel tank trailer?

fuel tanker accessories

baffle

The tank trailer is separated by baffles, which help to evenly distribute the force of the fluid under acceleration and braking. Since a truck's momentum varies with the fuel it contains, it can easily tip over without a baffle. The design method of baffle makes the tanker trailer running more safely.

top loading and bottom loading

The relief valve

The tanker trailer is fitted with multiple safety valves at the bottom to safely discharge the tanker. This often happens if a vehicle rolls under the trailer. It seems like a small security arrangement.However, it helps to avoid many accidents.

Fuel tanker trailer breathing valve is installed on the large cover of the tank,for sure that the pressure in the tank is basically consistent with the atmospheric pressure when the fuel tank is working.

When the oil in the tank is heated to expand or when an oil pump is used to fuel the tank, the oil level in the tank rises and the pressure increases. When the pressure in the tank is higher than the external pressure of 8KPA, the valve disc on the breathing valve is opened.

When the oil is discharged outwardly by the oil pump or when the oil is cooled and contracted, the oil level drops and the pressure decreases. When the pressure in the tank is lower than the external pressure of 3KPA, the lower valve plate of the respiration valve is opened.

Brake assist and low center of gravity

Today's fuel container trailers are sold with a brake assist system that ensures that under heavy braking, even in windy and slippery conditions, the tanker does not roll over and the driver does not lose steering control conditions. In addition, the lower center of gravity prevents the tank trailer from tipping over.

Special manholes

The manhole cover allows the tank to breathe in the event of overturning and fire. The manhole allows pressure or steam that builds up in the tank to escape without significant loss of the fuel contained. Manholes are the reason why tankers burn evenly when they catch fire, rather than exploding first, giving the fire brigade time to control the blaze.

manhole cover

Bottom valve

Seabed valve series, also known as emergency cut-off valve, installed at the bottom of the tank, can replace the traditional top type refueling for bottom refueling, convenient operation, time saving, safety and environmental protection. The valve body is designed to cut off a groove, in the event of an accident, the cutting groove is disconnected, under the premise of not affecting the sealing of the tank will be cut off the bottom of the pipeline and the tank, effectively prevent the oil leakage in the tank, so as to ensure the tank safety.

The breather valve

When the breathing valve is dumped 70o, the sealing ball inside the valve is dumped to form an effective seal to prevent oil leakage.

Application:

It is installed at the ready opening on the manhole cover and can be equipped with a dipstick or liquid level gauge.

The relief valve

Specially designed for oil tank, chemical tank and other tank products, according to user needs to set different opening pressure, to meet different needs. The main body is made of stainless steel, corrosion resistant, high sealing, suitable for all kinds of environment.

Anti-overflow sensor

Application: electronic anti-overflow sensor is widely used in all kinds of containers in the closed filling liquid, in order to prevent the liquid full leakage and advance alarm of a safety device, it is installed on the top of the container tank manhole cover, when the oil level reaches the warning limit, the sensor will automatically alarm off the brake.

What is fuel tank trailer DPF?

DPF is a new word for most fuel tanker trailer truck drivers, but as an important part of the engine of a fuel tanker semi-trailer, it is related to the wallet of the tanker drivers. Now let's take a look at this new gadget.

The high emission standards of tank semitrailers have led to the widespread use of DPF.

Diesel engines focus on controlling two types of emissions: nitrogen oxides (NOx) and particulate matter (PM). Among them, NOx is the product of complete combustion, while particulate matter is the product of incomplete combustion (black smoke).

Solutions to reduce pollutants:

The engine system mainly adopts two technical routes to achieve the exhaust standards:

① Selective catalytic reduction (SCR) system reduces NOx.

② Particulate matter trap (DPF) reduces particulate matter.

What is the DPF?

DPF, the Particle Catcher, is actually a large particulate filter that collects all the black smoke and other impurities produced by the engine, thus reducing particulate emissions.

DPF working process

These harmful substances will only cause problems, so DPF will find its own way to get rid of them.The collected smoke is burned through the exhaust heating, a process called DPF regeneration. The regenerated filter element can also be kept unobstructed, so that it does not affect engine performance due to congestion.

It is important to note here that regeneration is inevitable and will be triggered by the engine as soon as it detects a DPF block.

Methods of DPF regeneration include automatic regeneration and in situ regeneration

Automatic regeneration: when the engine of the fuel tanker trailer runs to the medium load, it will be automatically executed. For example, when the engine runs at high speed and dart, it will be automatically regenerated. When the engine is executed, it will be prompted by a high temperature light (regeneration needs to consume fuel to raise the temperature).

In-situ regeneration: for example, after a period of operation in low-speed and low-load conditions such as the city or traffic jam, the driver needs to pull the regeneration button on the vehicle to implement regeneration after stopping the vehicle. Usually in-situ regeneration can be performed when the regeneration indicator is turned on.

DPF soot cleaning

Does DPF regenerate and burn off the harmful particles and all is well?

Ash remains in DPF because it cannot be removed by heating or burning. Under normal circumstances (with CJ-4/CK-4 grade oil), ash will gradually clog the DPF after a certain mileage, so we have to carry out a series of maintenance such as regular dust removal.

The capacity of the fuel tank trailer

For 2-5 tons of oil (tank volume is about 6000 liters or less), light truck chassis can be selected, like running a small gas station or refueling for a construction site.

The oil loading capacity is 5-8 tons (the tank volume is about 6000-10000 liters). If you are fueling multiple sites or taking into account oil transportation operations, you can choose the large light truck chassis.

The oil loading capacity is 10-22 tons (the tank volume is about 120-25000 liters), such as the medium and long distance transportation of oil to the gas station, you can choose the medium and heavy truck chassis.

Large heavy-duty tanker trailer with oil loading capacity of more than 28 tons and long distance transportation generally adopts heavy truck chassis or traction head semi-hanger.

As a dangerous goods transport vehicle, what should be paid attention to?

With the rapid development of economy, the ownership rate of private cars is getting higher and higher, and the demand for oil products is also increasing, so the use of oil tanker trailer is also increasing, oil products are flammable goods, dangerous goods, then the potential safety risks will increase, so the use of oil tanker trailer will have a lot of matters needing attention.

1. There are no fireworks signs on fuel tanker trailers. A ban on fireworks is mandatory. Fuel tanker trailers on the road should avoid open fire, easy to produce static high voltage lines and other potentially dangerous road.

2. The fuel tank trailer will produce static electricity inevitably in the process of loading, unloading and driving, which is also need to pay attention.

First of all, the oil tank trailer must be installed with static electricity belt, which is the electrostatic grounding device, so that even if the static electricity, can also be transmitted to the underground by the static electricity to avoid the accumulation of sparks caused by spontaneous combustion.

Second to avoid personal charged, when loading and unloading operation, the body must contact with the oil tank truck, cause friction and generating electrostatic, electrostatic discharge meets flammable and explosive oil vapor, it is easy to happen explosion accident. Therefore in the process of operation, the operation staff must wear anti-static shoes, the purpose is to ground the human body, in addition, it is forbidden to paste insulation film on the anti-static sole , and check should be done regularly.

3. After oil loading, the grounding can only be disconnected after 5 minutes of oil stabilization. Because after the oil is loaded, the oil flows in the tank, causing the oil surface potential to remain for a few minutes.

4. Although the anti-static measures are very comprehensive, but in the operation or can not relax vigilance, in strict accordance with the operating procedures and pay attention to the hidden dangers that may appear at any time, at the same time to master correct emergency handling methods and rescue measures of all kinds of emergency.

5. Attach great importance to the "convert oil loading", the so-called transformation loading is the conversion of oil medium, such as original gas, now used for diesel, gasoline ignition point is lower than that of diesel, if the diesel injection into a containing gas steam tanks, pour diesel gasoline steam by absorption and reduce pressure, then the air is inhaled vats, and somewhere in between the liquid surface and air suction point to form a combustible mixture, electrostatic accumulation discharge can cause explosion. Therefore, in the "conversion of oil", the tank must be cleaned of gasoline, and in strict accordance with the operating procedures.

6. Use equipment that conforms to technical specifications and safety requirements. The automatic control, remote control, metering instruments, valves and other equipment of the loading oil station must be inspected regularly, and there must be a strict management system.The material of loading oil equipment can not be ignored, must use in accordance with the standard of loading oil equipment. For the common use of clamps and magnetic joint grounding, should not be randomly clamped or adsorbed in any part of the oil tank car, which is very unfavorable to anti-static, but also a big hidden trouble.
