There is a small "tail" on the tail of a tanker driving on the road in the city. Someone asked: Why is there a small "tail" behind the tanker? What is the use of this "tail" in the end? What is the principle? Next, Xiao Bian speaks for everyone. Behind the tanker is a small "tail" is actually an electrostatic belt, the main purpose is to ease the role of static electricity, security protection. The cause of static electricity in tank trucks is complicated: there are many reasons such as internal friction between oil and cans, external air and dust and oil tank friction, and external static electricity transmission. Even if the loading vehicle is stationary, the metal shell of the oil vehicle is charged due to the flow of air and dust and the conduction of static electricity from the outside (for example, on dry days, people are charged and the oil cart is touched by hand). This "tail" can then conduct these conducts to the ground. When the oil tanker is running, friction between the oil and the tank will break the neutral state of the two electric powers, so that the charge distribution of each part is uneven and electrostatic. At this time, the flow of oil on the one hand allows the oil and the tank to be charged. On the other hand, it can also neutralize the original electrification. However, with the outside world, the oil tanker can bring some static electricity as a whole. At this time, this “tail†has Discharge effect. Behind the tanker there is a small "tail" of electrical conductivity that does not always conduct electrons to the ground. If the fuel tanker is positive, it will transmit the earth's electrons to the car. Otherwise, the electrons in the car will be transmitted to the earth. In short, due to the conductive effect of this “tailâ€, the car does not accumulate static electricity, which is essential on every tank car, making the vehicle safer during use.
