Description

Technical Field

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

[0002] Grease is a semi-solid lubricant composed of a base oil, a thickener, and additives. Its primary function is to form a lubricating film between mechanical components, reducing friction and wear and, to a certain extent, protecting metal surfaces from corrosion. Grease's characteristics include adhesion, sealing, pressure resistance, long-lasting performance, protective properties, and thermal stability. Grease is widely used in various mechanical equipment, such as bearings, gears, chains, and slide rails, particularly in locations where frequent refueling is difficult or sealing conditions are poor. Choosing the right grease requires consideration of multiple factors, including operating temperature, load conditions, speed, and environmental factors.

[0003] Grease contains a lot of impurities. If it is not filtered, the impurities will act as abrasives between mechanical parts, increasing wear and causing premature failure of the equipment. At the same time, impurities may destroy the structure of the grease and affect its ability to form an effective lubricating film on the contact surface, thereby reducing the lubrication effect. At present, grease will leak during the transportation process, causing pollution to the environment, making the ground greasy, and increasing the risk of people slipping. At the same time, if the grease comes into contact with high-temperature parts or electric sparks, when the grease leakage accumulates too much, it may cause a fire and cause economic losses.
