For aero-engine in plant experiment or airflight, can fast and effectively start be that critically important one refers to
Mark.Existing double oil circuit swirl atomizers are in engine test or the course of work by occurring that spray nozzle clogging is pneumatically unsuccessful
Failure.Pneumatic oil piping system-auxiliary oil circuit of engine nozzle is designed for this, while to consider the low stain control of engine
System.Low pollution technique is tended to lean premixed direction and is developed, and burning is preceding that gas mixture is more uniform, and oil-gas ratio is low to be oil-poor,
Then pollutant is fewer.In order to realize two above-mentioned targets, usually require that double oil circuit swirl atomizers are constant in auxiliary oil circuit hole flow
On the premise of, the diameter of bore of nozzle body need to be reduced.Research is needed to be studied on double oil circuit swirl atomizers for this this and thin
Long pore structure conceptual design again, current existing swirl atomizer auxiliary oil circuit hole is typically all straight and aperture is larger, double oil circuits
Swirl atomizer is not easily accomplished oil-poor quick startup, therefore most of designs all control oil-poor open using air atomizer spray nozzle
It is dynamic, to obtain larger fuel-lean blowout border.
The content of the invention

A kind of double oil circuit swirl atomizer auxiliary oil circuit structures, its preferred solution are that the mounting hole angle of inclination is
5°-10°。
A kind of double oil circuit swirl atomizer auxiliary oil circuit structures, its preferred solution is for the aperture with nozzle opening by adopting
With electric spark guide sleeve together Combined machining, ensure concentricity.First, producing oil circuit deflection when preventing from processing respectively, flow resistance loss increases
The problem of big, second, preventing the solder flowing easy spray blocked on gas header pipe ring when gas header pipe ring is welded with nozzle body
The problem of oilhole.
Beneficial effects of the present invention：A kind of auxiliary oil circuit machine of new double oil circuit swirl atomizers of technical scheme design
The auxiliary oil circuit of swirl atomizer, is designed with the sleeve structure of certain angle by structure scheme, it may be difficult to which the pore of realization is decomposed into
Two parts are realized in twice manufacturing procedure.Design in this way, first, oil-poor startup can be solved, second, flow and public affairs
Have pressure difference it is constant on the premise of, increase auxiliary oil circuit pressure difference, realize it is quick start to reduce start the time, third, reducing fuel nozzle product
Dirt.The technical solution of this patent design is simple, conveniently, realizability it is strong, it is quick to solve under double oil circuit swirl atomizer auxiliary oil circuits
The design and processing problems of control.By using the fuel injection system of the structure, engine maintenance cost about 15% can be saved,
With huge economic benefit and social benefit.
