Description

Technical Field

[0001] The utility model relates to the technical field of lubricating oil filtering, in particular to a lubricating oil filtering device. Background Art

[0002] The existing lubricating oil filtering device generally includes a filter element. After the lubricating oil enters the filter chamber, it leaves the filter element through the filter holes. The impurities in the lubricating oil are blocked by the filter holes because they are larger than the filter holes and remain in the filter chamber. In this way, the lubricating oil can be filtered. However, the impurities remaining in the filter element are easy to clog the filter holes and affect the filtering efficiency. The existing device needs to be cleaned frequently and is not practical. For this reason, we propose a lubricating oil filtering device. Utility Model Content
