There are two sources of solid particles in lubricating oil:
- Raw materials such as base oil and additives are brought in by themselves.
- It is introduced through filling machine, pipeline and other system facilities.
The solid particles brought in by raw materials are generally small, while the particles introduced by filling machine, pipeline and other system facilities are generally large.
Of course, other factors at the customer’s site, such as packaging (iron and plastic barrels), the working environment at the filling site, the filling equipment and pipelines, also have a certain impact on the cleanliness of the final lubricating oil.
Effect of packaging on cleanliness:
The package of lubricating oil is generally divided into two kinds: iron bucket and plastic bucket. The iron barrel is produced by the roll sealing process, while the plastic barrel is produced by the blow molding process. Due to the limitation of their production processes, both of them will inevitably expose the package to the air, which will make the fine dust in the air enter the barrel. These impurities accumulated in the package will pollute the lubricating oil and affect the cleanliness of the lubricating oil.
Impact of working environment on cleanliness:
At present, the filling operation is carried out in a completely open space. During the filling process, a large amount of dust floating in the air of the working space will inevitably enter the package, thus affecting the cleanliness of the lubricating oil.
Impact of filling equipment on cleanliness:
Because the filling equipment (including pipeline, filling machine, etc.) is in direct contact with the lubricating oil, if its cleanliness is not high, it will pollute the cleanliness of the filtered lubricating oil.
