Metro package inspection X-ray machine
We can see the X-ray machine everywhere on the subway. Many passengers have such doubts. Why does the subway need security? It takes time to pass security checks every day. Especially during large-scale exhibitions and holidays, the flow of people is large and there are long queues. It is a waste of time to pass through the slow machine. For a long time, my heart is more or less in conflict. Why does the subway need to carry out security inspections? The main purpose is to prevent the occurrence of various security incidents and prevent the use of dangerous goods and contraband products on the train to protect the public's safety. What is the use of X-ray machines? It is used to detect whether the package carried by the body carries banned items such as gasoline, diesel, kerosene, spray, alcohol, rosin, paint, hydrogen peroxide, liquefied gas, solvent oil, detonators, explosives, fireworks, and other inflammable and explosive materials. . In the daily life of citizens, there are gasoline, diesel, kerosene, liquefied gas, calcium carbide, hair and mousse, all kinds of paints, glues, cleaning agents, toners, and brighteners that contain explosive ingredients. X-ray machine inspection principle? Mainly consists of X-ray tube and X-ray machine power supply and control circuit. The X-ray tube is composed of Cathod, Anode and vacuum glass tube. X-ray machine power can be divided into high voltage power supply and filament. Two parts of the power supply, in which the filament power is used to heat the filament, the high voltage output terminals of the high voltage power supply are respectively arranged at both ends of the cathode filament and the anode target, and a high voltage electric field is provided to accelerate the active electrons on the filament to flow toward the anode target to form a high speed electron Flow, after bombarding the anode target surface, 99 [%] converted to heat, and 1 [%] produced X-rays due to the Compton effect.
