Technical Field
The utility model relates to a civil aviation aircraft field, especially one kind is used for when the maintenance of civil aviation for the device of oil mixing between aircraft.
Background
The common point of the work is that the fuel quantity in the fuel tank of the airplane needs to be adjusted, some fuel tanks need to have a certain fuel quantity, and some fuel tanks need to be directly emptied. In the existing maintenance work, a refueling truck is arranged to operate by contacting with an aviation fuel company, fuel is filled into an aircraft fuel tank or the fuel in the fuel tank is pumped into the refueling truck, and then the aviation company continues to perform the maintenance work, so that the defects are as follows:
firstly, whether a refueling truck of an aviation fuel company fills fuel into a fuel tank of the airplane or pumps the fuel in the fuel tank of the airplane into the refueling truck, the aviation fuel company needs to pay, and even if the fuel is pumped out, the aviation fuel company only serves as a gift for pumping out service cost. Taking an empty fuel tank as an example, if an aircraft finishes a day's mission, 4 tons of fuel remain in the fuel tank, and the 4 tons of fuel are originally purchased from an oil company at a normal price. The fueling company also needs to be paid for pumping services if it is notified that the fueling vehicle is scheduled to draw fuel away. Before the airplane takes off the next day after the maintenance work is finished, the airline company needs to purchase 4 tons of fuel oil for the airplane to the oil pumping company, and besides the payment of oil pumping service cost, the total cost of 8 tons of fuel oil is wasted.
Secondly, maintenance work is mostly carried out at night, even the latter half night, and the oil filling company needs the dispatch tank service truck, and the tank service truck reaches maintenance work place and carries out work according to the navigation department's requirement, just so need wait for very long time can expand work.
Therefore, the current mode causes a great amount of economic loss for an airline company, and wastes the work and rest time of maintenance personnel. Therefore, a scheme for facilitating oil mixing between airplanes during airplane maintenance is needed, and the efficiency and the burden of an airline company are reduced.
