Aircraft refueling truck mainly drives fuel into aircraft tanks by pressure, and is divided into two types: tank type and pipeline type. The core equipment includes oil pump, pressure controller and special oil pipeline.
Main working process
Pressure drive: Use the oil pump to generate pressure (usually not more than 55 psi/379 kPa), and quickly inject fuel into the aircraft tank through the special refueling port under the wing. It is more efficient and safer than gravity refueling.
Equipment composition: Tank refueling truck: Contains oil tank, oil pump, pressure controller and flow meter, can complete refueling independently, with strong flexibility, suitable for scenes without underground pipeline network. Pipeline refueling truck: Relying on the underground fuel pipeline network of the airport apron for fuel supply, no need to bring your own oil tank, and other equipment is similar to the tank type. Safety and operation points
Static conduction device: Connect the vehicle and the aircraft to eliminate the risk of static electricity. Wheel block fixing: Prevent equipment damage caused by vehicle movement. Standardized docking: Use a lifting platform to accurately dock the refueling connector to the aircraft fuel tank port, and set up warning signs and emergency pull ropes to ensure that the oil source can be quickly cut off in case of an accident.
Applicable scenarios and advantages
Civil aircraft mainly use pressure refueling because it is efficient, safe and has strong anti-pollution capabilities; small aircraft may still use gravity refueling similar to cars due to design limitations.
