There are many types of machinery and equipment, as well as various working environments. For the choice of grease, in addition to normal conditions, in special circumstances, the requirements of grease are higher. The so-called special environment, not only refers to the space travel and high radiation irradiation and other extremely special environment, but also in general industrial production there are many special environment lubrication problems. This mainly refers to vacuum, high speed, high pressure, high temperature, low temperature and contact with water, solvents, chemicals and so on. Under such harsh conditions, it is also necessary to have high quality special grease or special grease suitable for its performance requirements, in order to ensure long-term lubrication.
In the operation of mechanical equipment, friction and wear is inevitable, sometimes necessary friction is the prerequisite for the normal operation of equipment; Such as the clutch on the motorcycle, the automatic gearbox on the car, the hydraulic coupling on the industrial equipment, the guide rail, etc., all need to have a certain friction on the surface of the parts that move each other. There is friction between the metal surfaces of mechanical moving parts. Even if the workpiece surface is finely processed to the degree of "mirror", when the metal surfaces move together, especially under heavy load, abrasion, melting and even sintering occur, which is manifested as mechanical friction and wear on the macro level.
Lubrication of mechanical equipment:
1) Reduce friction and wear: add lubricating materials between the friction surfaces of the machine or mechanism, so that the friction surface of the relative movement does not occur or as little as possible direct contact, so as to reduce the friction coefficient and reduce wear.
2) Cooling: in the operation of the machine, all the work consumed by friction will be converted into heat, causing the temperature of friction parts to rise.
3) to prevent corrosion: the lubricating grease layer on the friction surface can make the metal surface and air completely separated, to protect the metal from corrosion.
4) washing: the flowing oil film of lubricating grease can wash away the debris and other impurities formed by friction or oxidation on the metal surface to ensure the cleanliness of the friction surface.
Metals by mechanical movement, the friction and wear and tear, can choose high temperature wear resistance grease, it USES the total synthesis of special oil and special additives, which has strong oil film, resulting in mechanical operation of lubricating oil film can be persistent effectively maintain internal friction surface mechanical separation, ensure less mechanical wear and tear, or even run without wear and tear, Thus extending service life, increasing operational reliability and increasing mechanical tolerance to extreme conditions.
