Problems solved by technology
The commonly used aircraft fuel delivery sequence control system relies on the joint work of the float valve and the fuel electromagnetic switch. Since this method needs to set the float valve and the fuel electromagnetic switch for each fuel delivery tank separately, there are many accessories, which will increase the weight of the aircraft fuel system. and reduces the reliability of the aircraft fuel system

An aircraft fuel oil conveying sequence control system comprises an oil use-up annunciator, an oil conveying tank, a reversing solenoid valve, a mechanical and electric management computer, an oil conveying pump and a jet pump. The oil use-up annunciator is mounted at the bottom of the oil conveying tank, and the oil use-up annunciator and the reversing solenoid valve are connected with the mechanical and electric management computer. The reversing solenoid valve is mounted at an outlet of the oil conveying pump, meanwhile, a channel A of the reversing solenoid valve is connected with the outlet of the oil conveying pump, and an output channel of the reversing solenoid valve is connected with the jet pump. According to the aircraft fuel oil conveying sequence control system, the oil use-up annunciator which is arranged in the aircraft oil conveying tank is used, and the reversing solenoid valve is arranged so that the oil use-up annunciator and the reversing solenoid valve are made to work in a combined mode to achieve the control over oil conveying sequences. The aircraft fuel oil conveying sequence control system is small in number of accessories, simple in control logic, and capable of effectively lowering the weight of an aircraft fuel oil system; meanwhile, the reversing solenoid valve is electrically controlled through the electric reversing solenoid valve, and the reliability of the aircraft fuel oil system is effectively enhanced.
Description
technical field [0001] The invention relates to the technical field of aviation machinery control, in particular to an aircraft fuel delivery sequence control system. Background technique [0002] During the working process of the aircraft fuel system, the fuel in the fuel transfer tank needs to be transferred to the fuel supply tank. Since the fuel transfer tanks are distributed in different parts of the aircraft, it is necessary to design an automatic fuel transfer system to ensure that the fuel is transferred normally according to the set order. The commonly used aircraft fuel delivery sequence control system relies on the joint work of the float valve and the fuel electromagnetic switch. Since this method needs to set the float valve and the fuel electromagnetic switch for each fuel delivery tank separately, there are many accessories, which will increase the weight of the aircraft fuel system. And reduce the reliability of aircraft fuel system. Contents of the inventi...
