发动机用的润滑油、燃油、空气、冷却水,都要采用滤清器进行过滤。本文介绍几种常用的滤清器。(1)全流旋装式润滑油滤清器。这种滤清器的作用是过滤润滑油中的机械杂质和水分。传统全流式滤清器串联在主油道中,发动机全部的循环润滑油均通过它过滤。这种润滑油滤清器的流动阻力一般较小,过滤精度不高。目前,发动机的零部件之间的配合越来越精密,在要求润滑油 Engine lubricants, fuel, air, cooling water, should be filtered with a filter. This article describes several commonly used filters. (1) full-flow spin-on oil filter. The role of this filter is to filter oil in the mechanical impurities and moisture. Traditional all-flow filter in series in the main oil passage, the engine through the circulation of all the oil filter. The flow resistance of this oil filter is generally small, the filtering accuracy is not high. At present, the cooperation between the engine parts is getting more and more precise, requiring lubricating oil
