标准范围

ISO 28520:2009为润滑油系统的冲洗和由此产生的清洁度分级提供了指导。冲洗过程有两个方面:清除竖立和安装上的污垢，以及证明管道和整个系统足够清洁。曲轴箱和（如适用）变速箱等在冲洗前单独清洗，ISO 28520:2009也规定了与此相关的要求。类似的考虑适用于系统储罐和系统的其他部件。出于ISO 28520:2009的目的，当雷诺数等于或小于3 000时，清洗过程被认为是“冲洗”，当雷诺数等于或大于3 000时，清洗过程被认为是“冲洗”。在可能的情况下，任何原始设备制造商的冲洗要求优先于ISO 28520:2009中概述的要求。

ISO 28520:2009 provides guidance for flushing of lubricating oil systems, and grading of the resultant cleanliness. The flushing process is twofold:

• to remove dirt from the erection and installation, and
• to demonstrate that the pipes and the system as a whole is sufficiently clean.

Crankcase and, where applicable, gearbox etc. are cleaned separately before flushing, and requirements relating to this are also specified in ISO 28520:2009. Similar considerations apply to the system tank and other components of the system.For the purposes of ISO 28520:2009, the cleaning process is considered as “washing through” when the Reynolds is equal to or less than 3 000 and “flushing” when the Reynolds number is equal to or greater than 3 000.Where available, any original equipment manufacturer requirements for flushing take precedence over the requirements outlined in ISO 28520:2009.
