[0002] The thin oil station is the heart of the thin oil circulation lubrication system. Its function is to force the lubricating oil to the friction parts of the machine. The thin oil station is mainly used in the centralized lubrication system of dynamic and static pressure or sliding shoe bearings of mechanical equipment such as metallurgy, mining, and cement. The lubricating oil will be discharged after the machine is lubricated, and finally return to the oil storage tank inside the thin oil station through the pipeline. The returned lubricating oil will contain a large amount of impurities. If these impurities flow directly into the oil storage tank without treatment, they will pollute the quality of the lubricating oil in the entire tank. Once the lubricating oil containing impurities re-enters the equipment, it will cause damage to the internal components of the equipment. Therefore, how to improve the filtration effect of the return lubricating oil is the top priority to ensure the normal operation of the equipment. Utility Model Content
