How much do you know about a "character" aircraft refueller?
When we go out and there is no oil in the vehicle, we will go to the gas station to refuel the vehicle. Sometimes we can still see the refueling vehicles that are transporting oil for the gas station. This may cause people to have a refueling vehicle that can only be used for The impression of ordinary vehicles refueling. In fact, the refueling vehicle can not only transport oil for the gas station, but also can add fuel to the aircraft. We call it an aircraft refueling vehicle for vehicles that refuel the aircraft. The aircraft refueling truck is a special vehicle designed to provide refueling and pumping for aircraft. The aircraft uses aviation kerosene. This kind of fuel is different from ordinary diesel and gasoline. It is corrosive to common metals, so The requirements for the professional performance and safety configuration of such vehicles are even higher. Although the aircraft refueling vehicle is basically the same as an ordinary refueling vehicle, there are some special requirements in terms of performance and structure. Let's take a look together. 1, the refueling pressure stability requirements are high. To this end, pressure regulators, regulators, and pressure refuelling tables are installed on the refueling line. 2, the cleanliness of oil is high. High-performance filter separators are used on the oil. Tanks and pipes must be made of aluminum alloys. 3, absolutely guarantee refueling safety. ESD devices, interlocking control systems, electrical explosion-proof devices, and fire extinguishers should be installed. 4, equipped with high precision, large flow meter. 5, the tank's total capacity is large, to the aircraft to complete the fuel. For example, the capacity of the WG series tanker trucks is 10,000, 15,000, 18,000, 20000, 22,000, and 45,000L. The capacity is tens or even hundreds of times the capacity of an ordinary truck tank. Summary: Actually, aircraft refueling vehicles are not as mysterious as we thought. In addition to the performance and configuration requirements higher than the general refueling car, the other is no different from ordinary refueling vehicles.
The similarity in external appearance of the various alloys, along with the different combinations of elements used when making each alloy, can lead to confusion when categorizing the different compositions. There are as many as 400 different copper and copper alloy compositions loosely grouped into the categories: copper, high copper alloy, brasses, bronzes, copper nickels, copper–nickel–zinc (nickel silver), leaded copper, and special alloys.
