清洁度检测

Cleanliness testing

清洁度是指物体(零件或产品)在规定的范围内残留的污染物的量。

Cleanliness refers to the amount of contaminants that are left in the specified range of objects (parts or products).

污染物的量包括种类、形状、尺寸、数量、重量等衡量指标;具体用何种指标取决于不同污染物对产品质量的影响程度和清洁度控制精度的要求。

The influence factor of pollutants including type, shape, size, quantity, weight and others,

The specific choice of factor depends on the impact of different pollutants on the quality of the product and the cleanliness of the control accuracy of the requirements.


零部件表面污染物多为切屑、毛刺、铸沙、焊渣、磨料等固体颗粒。这些污染物会加速零件的磨损,擦伤配合表面,破坏润滑油膜,使得零件温度升高,润滑油变质;会堵塞元件的节流孔使元件失去调节功能,或者进入滑阀间隙使阀芯卡死,或者拉伤油缸内表面使泄漏增加或使输出力减小,或者损坏泵的配油盘使泵烧伤或研死。这些情况的出现最终将系统功能丧失或彻底瘫痪。

The surface contamination on parts and components are debris, burr, casting sand, welding slag, abrasive and other solid particles. These pollutants will accelerate parts wear, scrapes with the surface, damage of the lubricating oil film, so that the parts temperature rise, lubrication oil deterioration; components of the orifice plug the components failed to regulate the function, or slide valve clearance into the spool stuck, or pull a cylinder inner surface enable leakage increase or reduce the output force, or damage the pump with oil pan. The pump burn or research death. The appearance of these cases will eventually be lost or completely paralyzed system function.

因此,必须从每个环节的每一个细节入手来防止和减小污染物的产生,才可能保证安装后的系统能够安全可靠的运行。

Therefore, it is necessary to prevent and reduce the generation of pollutants from every detail in all links, and to ensure that the system can run safely and reliably after the installation.
