Abstract

Translated fromChinese

本发明涉及发动机甩油盘领域，包括甩油盘主体、进油孔、异形扰流柱、外侧扰流柱、喷油孔组成。甩油盘主体呈中部贯通的圆盘状，盘体内部为空腔。空腔内部包含与上下盘面结合的异形扰流柱和常规扰流柱。燃油经狭长的进油孔高速撞向异形扰流柱，异形扰流柱锯齿状的突起使燃油迅速被撕裂而破碎。燃油再经与常规扰流柱以及燃油之间的多次碰撞，达到良好的雾化效果。即使在低流量工况下，狭长的进油口也能使燃油高速喷出，经碰撞后达到很好的燃油雾化效果，从而提高了燃烧效率，提升发动机整体性能。

The invention relates to the field of an engine oil slinger, comprising a main body of an oil slinger, an oil inlet hole, a special-shaped spoiler column, an outer spoiler column and an oil injection hole. The main body of the oil throwing pan is in the shape of a disc with the middle part running through, and the inside of the pan is a cavity. The inside of the cavity contains a special-shaped spoiler column and a conventional spoiler column combined with the upper and lower disk surfaces. The fuel collides with the special-shaped spoiler column at high speed through the narrow and long oil inlet hole, and the jagged protrusions of the special-shaped spoiler column cause the fuel to be quickly torn and broken. The fuel is then repeatedly collided with the conventional spoiler column and the fuel to achieve a good atomization effect. Even under low flow conditions, the narrow and long fuel inlet can enable the fuel to be ejected at a high speed, and achieve a good fuel atomization effect after collision, thereby improving the combustion efficiency and improving the overall performance of the engine.

一种带有异形扰流柱的甩油盘An oil slinger with a special-shaped spoiler column

技术领域technical field

本发明属于燃气轮机燃烧室领域，具体涉及一种带有异形扰流柱的甩油盘。The invention belongs to the field of gas turbine combustion chambers, and in particular relates to an oil slinger with a special-shaped spoiler column.

背景技术Background technique

燃气轮机作为一种常见的动力装置，其性能的改善对诸多行业以及环境都会有巨大的益处。为了提高燃气轮机的燃烧效率、减少污染排放，对燃料的雾化效果研究是其中的重要环节。燃油的雾化效果关系到燃油能否完全燃烧，能否与空气达到良好的掺混效果，从而实现燃油的高效燃烧，提高燃烧效率并降低污染物的排放。因此，甩油盘对燃油的雾化实现效果，显得尤为重要。As a common power plant, the improvement of gas turbine performance will have huge benefits for many industries and the environment. In order to improve the combustion efficiency of gas turbines and reduce pollution emissions, the research on the atomization effect of fuel is an important link. The atomization effect of the fuel is related to whether the fuel can be completely burned and whether it can achieve a good mixing effect with the air, so as to realize the efficient combustion of the fuel, improve the combustion efficiency and reduce the emission of pollutants. Therefore, it is particularly important to realize the atomization effect of the oil thrower on the fuel.

甩油盘是用于小型发动机的供油装置。它通过甩油盘的旋转对燃油做功，使燃油从喷油孔高速喷出，实现燃油的雾化。而甩油盘的转速一般与发动机转轴的转速一致，随其变化。燃油的雾化质量与转轴的转速直接相关，高转速时雾化效果较好，而低转速时质量则较差。较差的燃油雾化效果会带来较低的燃烧效率以及较高的污染排放。因此，提高甩油盘低转速时的雾化效果能有效解决上述问题。A slinger is an oil supply device for small engines. It works on the fuel through the rotation of the oil thrower, so that the fuel is sprayed out from the fuel injection hole at a high speed to realize the atomization of the fuel. The speed of the oil slinger is generally consistent with the speed of the engine shaft, and changes with it. The atomization quality of the fuel is directly related to the speed of the rotating shaft. The atomization effect is better at high speed, and the quality is poor at low speed. Poor fuel atomization results in lower combustion efficiency and higher pollution emissions. Therefore, improving the atomization effect of the oil slinger at low rotation speed can effectively solve the above problems.

发明内容SUMMARY OF THE INVENTION

本发明要解决的技术问题是提出一种带有异形扰流柱的甩油盘，通过设置狭长的进油孔，提高燃油进入甩油盘盘腔的速度。通过设置两种扰流柱，提高燃油经过甩油盘的雾化效果，并强化燃油与燃烧室内空气的掺混效果。最终达到提高燃油雾化效果，提高燃烧室内的燃烧效率，减少污染排放的目的。The technical problem to be solved by the present invention is to provide an oil slinger with a special-shaped spoiler column. By setting narrow and long oil inlet holes, the speed of fuel entering into the cavity of the oil slinger is increased. By setting up two kinds of spoiler columns, the atomization effect of fuel passing through the oil slinger is improved, and the mixing effect of fuel and the air in the combustion chamber is enhanced. Finally, the purpose of improving the fuel atomization effect, improving the combustion efficiency in the combustion chamber and reducing pollution emissions is achieved.

结合图1，2，本发明提供了一种带有异形扰流柱的甩油盘。With reference to Figures 1 and 2, the present invention provides an oil slinger with a special-shaped spoiler column.

具体过程：燃油经进油孔2进入甩油盘腔体，细长的进油孔2使得燃油进入盘腔时具有更高的速度。高速的燃油射流经异形扰流柱3，被迅速撕裂破碎成大量小液滴。然后燃油小液滴进入外侧扰流柱5区域，在此区域内，大量的小液滴及液雾与外侧扰流柱5进行强烈密集的碰撞，并附带有液滴自身之间的相互碰撞，使得燃油液滴尺寸更小。然后，燃油经喷油孔6被甩入燃烧室内，实现更高质量的雾化效果，使得燃烧更充分，提高了燃烧效率。The specific process: the fuel enters the oil throwing pan cavity through theoil inlet hole 2, and the slenderoil inlet hole 2 makes the fuel have a higher speed when entering the pan cavity. The high-speed fuel jet passes through the special-shaped spoiler column 3 and is quickly torn and broken into a large number of small droplets. Then the small droplets of fuel enter the area of theouter spoiler column 5. In this area, a large number of small droplets and liquid mist collide strongly and intensively with theouter spoiler column 5, and there are also collisions between the droplets themselves. Makes the fuel droplet size smaller. Then, the fuel is thrown into the combustion chamber through the fuel injection hole 6 to achieve a higher quality atomization effect, making the combustion more sufficient and improving the combustion efficiency.
