The car is running out of gas. The first time you think of it is to refuel at a nearby gas station. For a slow-moving construction machinery vehicle, refueling at a gas station delays time and affects work efficiency. , Mobile refueling vehicles can also refuel small cars that do not want to move, which is convenient and fast. Today we are going to introduce aircraft refueling vehicles. As the name implies, they are specific models for refueling aircraft. Its configuration and operating system can be said to be safe, high-end, advanced, and more Kind of security.
So what is the difference between an aircraft fuel truck and an ordinary fuel truck?
One. Different structure
Aircraft fuel trucks: due to the complexity of the operating system, the space required is relatively large. At the same time, the refueling status and pressure changes need to be observed at any time during the fueling process. The operating system, including the pump inlet and pump outlet, is often separately installed in front of the tank, and some are also installed in the tank. The rear of the body, this advantage is that standing is convenient for operation;
Ordinary fuel truck: The operating system of the ordinary fuel truck is installed in the tool box on both sides of the tank. The special configuration is relatively small, and the operation is simple. There is enough space for installation on both sides of the tank. The layout is more compact and the length of the entire vehicle is unchanged. In the case of making full use of the space above the chassis as a tank, the volume of the tank is larger, and more oil can be pulled in one trip.
two. Different loading media
Aircraft refueling vehicle: Aircraft refueling vehicle only refuels the aircraft, the medium loaded is aviation kerosene, which is a petroleum product;
Ordinary refueling vehicle: The ordinary refueling vehicle refuels different types of vehicles, and the medium loaded is mostly diesel, gasoline, etc.
three. Different materials
Aircraft fuel trucks: As aircraft fuel trucks are loaded with aviation kerosene, kerosene will corrode conventional metals. The tank body we use is magnesium aluminum alloy, also known as anti-rust aluminum alloy, which can play a role in anti-corrosion and anti-rust. Valves and pumps are made of stainless steel, and polished and waxed to ensure the safety of kerosene;
Ordinary refueling vehicle: the barrel is usually made of carbon steel or 5083 aluminum alloy, the pipes and valves are made of aluminum alloy, the protective bars on both sides of the tank, the tool box, the rear bumper, and the upper and lower tank ladders are made of aluminum alloy to reduce The weight of the whole vehicle can pull more oil when the total mass is unchanged.
four. Special configuration
Aircraft fuel truck:
1. Aircraft fuel trucks should be installed with a pressure regulator to adjust the pressure, regulator and fuel pressure gauge. Observe the pressure of the fuel and the pump when it enters and exits at any time and make corresponding safety adjustments. It is often installed at the top of the tank. The location is clearly visible;
2. Aviation oil has very high requirements on the purity of the oil. High-performance filters will be installed on the pipeline. The aviation kerosene will be highly filtered before entering the aircraft fuel tank. Sampling will be conducted before and after the filtration to check its purity. Ensure that every drop of oil entering the aircraft is safe and secure;
3. The FQJ type float level gauge is installed on the tank of the aircraft fuel tank, which can keep abreast of the oil level in the tank at any time, and make preparations for completing fueling in advance according to the amount of remaining oil;
4. Super-large flow meter, equipped with a super-large flow meter at the stainless steel pump, which accurately counts the amount of fuel added to the aircraft, and the measurement is accurate and safe. According to the installation position, pump out metering, pump in metering or pump in and pump out metering methods are available. ;
5. Engine tachometer, under the condition of the power take-off, the engine speed should not exceed 1000r/min. The engine tachometer can observe the speed at any time. If it exceeds the specified speed, it can be extinguished. The pump oil system is marked on the side next to the tachometer. Flow chart and valve switch indicator table can help the operator to understand the progress of fueling and valve opening more accurately;
Ordinary fuel truck:
The configuration of the ordinary fuel truck is basically the standard configuration of the tank truck, the European standard tank port, the bottom oil system, the oil and gas recovery system, the anti-overflow probe, the pump in and pump out, etc. These are necessary for the gas station to pull oil Configuration, measurement method can choose flow meter or fuel dispenser, on the premise of ensuring the account, users can customize special configuration according to needs.
In addition to the above differences, the refueling site of the aircraft refueling vehicle has undergone multiple layers of protection measures, including the isolation of engine heat dissipation and oil pipelines, interlocking control switches, anti-static devices, and the engine can be shut down through the emergency stop button in case of emergency. 100% Ensure the safety of aircraft refueling.
