Problems solved by technology

[0003] At present, the main form of the oil throwing plate is the oil throwing hole. Due to the small fuel atomization cone angle, the fuel output of the fuel injection hole is not uniform enough, resulting in uneven fuel atomization effect and uneven temperature distribution at the outlet of the oil throwing plate.

Embodiment Construction

[0018] The present invention will be further described now in conjunction with accompanying drawing:

[0019] to combine figure 1 , figure 2 , the invention is an oil flinger with a droplet type spoiler.

[0020] When the oil slinger is working normally, the fuel enters the cavity of the oil slinger through the oil inlet 2, and then enters the flow equalizer 3, and the evenly arranged flow equalizer outlet 4 makes the fuel evenly distributed and enters the main cavity, facing the flow equalizer The sharp part of the head of the droplet spoiler 5 of the outlet 4. At this time, due to the high rotational speed of the oil flinger, the fuel directly collides with the sharp part of the droplet spoiler 5 at a very high speed, and the fuel block is quickly torn into pieces. In addition, the drop-shaped spoiler 5 will cause the broken fuel to collide with the ball-shaped spoiler 6 at a high speed with relatively low kinetic energy loss. The small, dense and staggered spherical sp...

Abstract

The invention provides an oil flinger with water drop type turbulent flow columns. The oil flinger is an oil supply device for a small engine, and a gas turbine with the oil flinger is high in combustion efficiency. The oil flinger is composed of a main disc body, a flow divider, water-drop-shaped turbulent flow columns, spherical turbulent flow columns and convergent spray holes. By arranging the flow equalizer, fuel oil can reach the combustion chamber more uniformly. By arranging the water-drop-shaped turbulent flow columns and the spherical turbulent flow columns, under the action of centrifugal force, fuel oil with high kinetic energy is fully collided after being torn in the disc body, and the good atomization effect can be achieved. The convergent nozzle enables fuel oil to enter the combustion chamber at a higher speed, and the fuel oil and air in the combustion chamber violently act, so that the mixing and atomizing effects are improved, and the combustion efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of combustion chambers of gas turbines, and in particular relates to an oil throwing pan with a droplet-shaped spoiler column. Background technique [0002] The oil flinger is a special form of fuel nozzle, mainly used in high-speed, low-flow baffle annular combustion chambers, as a fuel supply device for small engines, with good atomization effect and simple structure. Compared with conventional nozzles, it has the advantages of low oil supply pressure (the high-pressure oil supply device is omitted), simple structure, light weight, low processing accuracy requirements, and good atomization performance; and compared with the evaporation tube, it has the advantages of simple and rapid startup Etc. The hole type oil throwing plate is a common oil throwing plate, and the oil throwing plate is installed on the main shaft of the engine and rotates synchronously with the main shaft. The fuel is sent to the ring...
