【摘要】：为了研究航空发动机动压式油气分离器的分离性能,采用容积法判别分离效率,并以此为据对结构形式、筒体直径及长度、入口管倾斜角和出气管长度等因素对分离性能的影响进行了研究。结果表明:采用内置式出气管与切向出油管相结合的形式,可使分离性能达到最佳;实验工况范围内,大的筒体直径更易于油气分离;入口管倾斜角存在最佳值,其值在10°~15°;当出气管长度取0.2~0.22倍分离器长度时,分离性能最佳;分离器长度过长会降低分离性能,实验条件下选5倍筒体直径为宜。
[Abstract]:In order to study the separation performance of aero-engine dynamic pressure oil and gas separator, a volumetric method is used to determine the separation efficiency. The influence of the angle of the inlet tube and the length of the outlet tube on the separation performance was studied. The results show that the best separation performance can be achieved by the combination of the built-in outlet pipe and the tangential tubing, the larger diameter of the cylinder is easier to separate oil and gas, the optimum angle of the inlet tube is 10 掳~ 15 掳. When the length of the outlet pipe is 0.22 times of the separator length, the separation performance is the best, and the separation performance will be reduced if the separator length is too long, and 5 times the diameter of the cylinder should be selected under the experimental conditions.
