机油滤清器检测
摘要：发动机的润滑机油在工作一段时间后，其中混有发动机零部件摩擦产生的金属屑和其他杂质产生；另外还有外来杂质，如空气中的尘土通过呼吸管、加油口等处进入曲轴箱；以及机油本身产生的胶质机油本身氧化过程中的产物，如各种有机酸，焦质沥青以及碳化物会随同机油进入润滑油道，从而加速发动机的磨损，造成油路堵塞；还有漏入浊底壳的水等。这些杂质会促进零部件的磨损，产生腐蚀或咬死运动件。因此在发动机的润滑系统中必须增设机油滤清器，以滤除上述存在于机油中的有害杂质，保护主机零部件，延长其使用寿命。一般的，机滤上游是机油泵，下游是主油道。

Abstract: The lubricating oil in the engine after a period of work, including engine parts, mixed with metal particles generated by friction and other impurities; in addition to foreign impurities such as dust in the air through the breathing tube into the crankcase oil filler, etc. ; and the oil itself glial oil itself is the product of the oxidation process, such as various organic acids, and carbon coke asphalt oil into lubricants Road will be accompanied to accelerate engine wear and tear, resulting in oil block; still missing Bottom of water into the cloud. These impurities will promote the parts wear, corrosion, or killed by moving parts. Therefore, in the engine lubrication system, oil filter must be added to filter out the presence of harmful impurities in the oil and protect the host component, extending its life. General, filter upstream of the oil pump, oil is the main channel downstream.
Key Words: engine; impurities; oil filter; parts.
