Abstract
The invention belongs to the technical field of fuel pumps, in particular to a multifunctional fuel pump. According to the multifunctional fuel pump, the split type single pump case and double pump core structure and design are adopted; pump cores are independently controlled, one pump core works in the normal fuel conveying process, and the other pump core is subjected to cold standby; when fuel needs to be conveyed simultaneously or drained emergently, the double pump cores work, the requirements of pressure and flow of the fuel conveying state and the emergent fuel draining state can be met, and the fuel conveying reliability is improved; by adopting the single pump case design, the occupied space can be reduced, and the weight can be reduced; the split type self-sealing valve design is adopted, when the pump cores are disassembled, the fuel in a fuel tank does not need to be drained, cables are prevented from entering the fuel tank, and the safety and the maintenance performance of a fuel system are improved.
Description
Technical field
The invention belongs to fuel pump technical field, particularly a kind of multifunction burning oil pump.
Background technique
For installing space and weight demands higher aircraft fuel system design, raising system plyability function becomes a main trend, traditional aircraft fuel system design, oil transfer pump and fuel jettison pump independent design, installing space occupy-place is more, and the weight cost paid is comparatively large, and pump case pump core does not adopt split type self-styled valve design, maintainability is poor, cannot meet design requirement.
Summary of the invention
The object of the invention is, propose a kind of multifunction burning oil pump can saved space, be convenient to maintenance.
Technological scheme of the present invention is: described fuel pump comprises fuel oil suction port 1, self-styled valve 2, pump case 3, check valve 4, pump core 5, control switch 6, it is characterized by: in pump case 3, have two cover pump cores 5, fuel oil suction port 1 and self-styled valve 2, two cover fuel pumps share an oil outlet, are provided with two independently check valves 4 at oil outlet place;
Two cover fuel pumps control by control switch 6 is independent;
When extraction pump core 5, self-styled valve 2 realizes pump case 3 isolates with fuel oil.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
In figure: fuel oil suction port 1; Self-styled valve 2; Pump case 3; Check valve 4; Pump core 5; Pump core control switch 6; Wingbar 7.
Embodiment
A kind of multifunction burning oil pump, adopts single pump case double pump core structure designs, is made up of fuel oil suction port 1, self-styled valve 2, pump case 3, check valve 4, pump core 5, control switch 6.This invention is installed on fuel tank inboard wing beam 7, fuel oil by two independently fuel oil suction port 1 enter fuel pump through self-styled valve 2, through pump core 5 supercharging by collecting outflow after two independently check valve 4.Two fuel pump cores 5 control by control switch 6 is independent, during normal oil transportation, single pump core work, another pump core cold standby can improve oil transportation reliability, oil outlet set up two independently check valve 4 can prevent fuel oil from flowing backwards, interference; When needing fuel dump, double pump core works simultaneously, meets pressure and the traffic requirement of fuel dump.
This invention can meet pressure under oil transportation and fuel dump two kinds of working staties and traffic requirement, and reduce installing space, weight loss effect is obvious.Pump case 3 and pump core 5 adopt split type independent design, and cable is oil-feed tank not, and when pump core 5 needs to safeguard, fuel oil can be isolated by self-styled valve 2 automatically, without the need to releasing fuel oil in fuel tank, improves oil-fired system Security and maintainability.
