为保证内燃机工作的可靠性,发动机机油的滤清问题甚为迫切。发动机设有各种结构的过滤器以分离发动机机油中的大量杂质,其中包括离心式机油滤清器。但离心式机油滤清器如2МЦН-3П型的机油滤清度不高。被污染的机油在以较大角速度(523.6～628.3rad/s)回转的转子内流动,且大多在最小压力区,即在转子旋转轴的附近,未受到离旋转轴最远转子区内离心力的作用。该缺点可用图1所示液体滤清用的新型离心器来消除。离心器由装在空心回转轴2上的转子1、配置在转子内的圈盘3、中心区的溢流孔4和隔板5组成。当机油在回转的滤清器转子内径向运
In order to ensure the reliability of the internal combustion engine, engine oil filtration is urgent. The engine has a variety of structural filters to separate large quantities of impurities in engine oil, including centrifugal oil filters. However, centrifugal oil filters such as 2МЦН-3П-type oil filter is not high. The polluted oil flows in the rotor rotating at a relatively high angular velocity (523.6 to 628.3 rad / s) and mostly in the area of minimum pressure, ie near the axis of rotation of the rotor, which is not subjected to centrifugal forces in the farthest rotor zone of the rotating shaft effect. This disadvantage can be eliminated with the new centrifuge for liquid filtration shown in FIG. The centrifuge consists of a rotor 1 mounted on a hollow rotating shaft 2, a rim 3 arranged in the rotor, an overflow hole 4 in the central area, and a partition 5. When the oil in the rotating filter rotor within the radial transport
