How to design the partition in the lubricating oil tank
Thread Content
For example, what size of holes should be made in the partitions of the lubrication system, and how much chamfering is required. What is the relationship with the return oil flow rate?
I remember that the purpose of this partition in the fuel tank is to prevent the returning fuel from stirring up the impurities at the bottom of the tank, thereby reducing such effects. Therefore, there is no specific height requirement; generally, after oil is discharged, this partition should be about 100 to 200 millimeters below the oil level.

Under normal circumstances, the level of the working oil is above the partition. In some cases, the partition is not fully welded to the bottom of the oil tank; there are many holes in it to prevent the oil pump from suddenly drawing in air； The partitions serve to buffer the oil, and some of them also help to settle impurities in the oil.
The partition complicates the path from the oil return port to the oil suction port, allowing impurities in the oil to settle as much as possible and gases to be released.
