Misunderstandings in the maintenance of tank trucks

On November 6, 2021, a serious explosion occurred at a gas station in Freetown, the capital of Germany, killing at least 92 people. The flame spread immediately, engulfing passengers in the car and nearby pedestrians.

In 2016, a tanker explosion occurred in Kenya, causing dozens of casualties. Many of them were hit by the second explosion because they flocked to the scene to collect fuel from a damaged tanker.

In 2019, a tanker explosion occurred in Tanzania, resulting in 85 deaths. A similar story happened in Congo in 2018, killing about 50 people.

Oil tanker explosion accidents are not uncommon. It can be seen that tanker maintenance is essential to reduce the danger caused by the tanker's own problems. What do you know about the misunderstandings of tank truck maintenance?

As one of the dangerous goods transport vehicles, how much do you know about the maintenance of a tanker truck? We all know that no matter what kind of vehicle needs to be maintained, there will be misunderstandings in the maintenance. You know about the misunderstanding of the maintenance of a tanker truck. ?

 Misunderstanding 1: Always charge the tire pressure very high. Many drivers like to adjust the tire pressure to a high level. They think it can save fuel and overload. In fact, if the tire pressure is too high, the tire’s ground contact area will be reduced. Braking effect, there is no doubt that this will affect driving safety; but too low tire pressure is not good, too low tire pressure will accelerate the wear of the tire shoulders, it will increase the fuel consumption of the vehicle, and it will also affect the driving safety and the vehicle's safety. Braking effect.

Misunderstanding 2: Always fill the engine oil very full. Many drivers always worry that the engine oil is not enough and always fill it up. But many people don’t know that too much oil will increase the crank connecting rod. The rotation resistance of the mechanism will also increase the amount of oil splashing on the cylinder wall. Excessive oil will also increase the carbon deposit in the combustion chamber and reduce the engine power, thereby affecting emissions. In fact, the amount of oil cannot be too large, but not too small. Generally, it should be added according to the scale on the oil scale. The oil level should not exceed the upper limit of the scale at most, and the lowest should not be lower than the lower limit of the scale. The oil level is above the middle of the scale.

Misunderstanding 3: Fix each bolt of the vehicle too tightly. Under normal circumstances, the bolts of various parts of the tank truck, according to their diameter, pitch and purpose, have corresponding tightening torques, and they cannot reach the specified torque bolts. Will loosen, and the bolts that exceed the tightened torque will be elongated. When we tighten the bolts, we must know the tightening torque of the bolts.

Misunderstanding 4: I always feel that the belts of the accessories are better than loose. Many owners of tank trucks think that increasing the tightening of the belts of the accessories can improve the cooling effect of the compressor and the power generation of the generator. In fact, this approach is wrong. of. The accessory belt should maintain proper tension, because too tight the belt will cause excessive load on the bearing, shorten the service life of the components, and cause the belt to break, which will eventually affect the normal use of the vehicle.
