Description

Technical Field

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

[0002] Lubricant base oil is the basic raw material for manufacturing various lubricant products. Therefore, its quality is directly related to the performance and reliability of the final lubricant product. The filter device can effectively remove impurities and pollutants in the base oil, improve the quality and purity of the base oil, and thus ensure the quality of the final lubricant product. During the production and storage process, some solid particles, such as metal particles, sand, dust, etc., will be entrained in the base oil. These solid particles will cause wear and abrasion to mechanical equipment, reduce the service life of the equipment, and cause failures and accidents. Removing these solid particles through the filtering device can reduce the wear of the equipment, extend the service life of the equipment, and improve the reliability and stability of the equipment; moisture and dissolved gas are common pollutants in the base oil. They will cause the foaming, oxidation and acidification of the lubricating oil, and reduce the performance and stability of the lubricating oil. The filtering device adopts special filtering materials and structures to effectively remove moisture and dissolved gases, reduce the oxidation and acidification reactions of the lubricating oil, and keep the lubricating oil clean and stable; there will be some colloids and precipitates in the base oil. These substances will cause the lubricating oil to have problems such as increased viscosity, precipitation and agglomeration, and reduce the fluidity and lubricating performance of the lubricating oil. The filtering device can effectively remove colloids and precipitates through reasonably designed filtering structures and filtering materials, maintain the cleanliness and fluidity of the lubricating oil, and improve the lubrication effect and the service life of the lubricating oil.

[0003] At present, in the filtration of lubricating oil, the existing filtering device only relies on the filter screen and the gravity of the lubricating oil itself to filter out impurities, and the filtering efficiency is low. Utility Model Content
