What is the mystery of the iron chain at the end of the tanker?
Tanker trucks are special vehicles that are mainly used to transport various oils and liquid chemicals. Most of them are flammable and explosive materials. Because the bodies are all metal, they are prone to static electricity and can have more or less impact on the various circuits of the vehicle. When the tanker is loaded with flammable and explosive materials, it is very dangerous. The oil or chemicals in the tank body will generate static electricity due to shaking and friction on the barrel wall. In serious cases, it will cause a fire and cause explosion, and bring safety to people and property. Huge harm and loss. So how should we avoid this happening? Usually, we will use a chain to install in the tail and connected to the ground, there are also using plastic strips, just like the grounding principle in the circuit. When the iron chain (rubber strip) rubs against the ground, it will also generate a charge. If the vehicle has a positive charge, the negative charge of the ground will be transmitted to the car through the iron chain (rubber strip). On the contrary, if the vehicle is negatively charged, the ground is positive. The charge is transmitted to the car through the iron chain (rubber strip) because the potential on the ground is zero. Whether the vehicle is positively or negatively charged, as long as it is connected to the ground, the electric potential of the car body is infinitely close to zero. This eliminates the static electricity and avoids the safety hazards caused by static electricity accumulation. How do we know if the chain is in contact with the ground? In addition to the usual checks, there is also a detection device that can be mounted on the vehicle to detect the resistance between the chain (rubber strip) and the ground to determine the connection. When the resistance is too large, an alarm will be issued to remind the vehicle. The personnel inspected and corrected the troubles in time: Pull out the strips of the mopping ground, or put the chain out for a few sections. If the strip or chain cannot be used any longer, replace it immediately or find another one to make sure that it can contact the ground. For the safety of people and vehicles, be sure to install electrostatic devices on the car. Do not be coveted for momentary effort and cause inestimable consequences.
