The role of lubricants

Lubricants are liquid lubricants used in various types of machinery to reduce friction and protect machinery and workpieces. They mainly act as lubricants, cooling, rust prevention, cleaning, sealing and buffering. Lubricants account for 85% of all lubricating materials. There are various types of lubricants, and the world's annual consumption is about 38 million tons. The general requirements for lubricants are:

(1) Reduce friction and wear, reduce frictional resistance to save energy, reduce wear to prolong mechanical life, and increase economic efficiency;

(2) Cooling requires that friction heat be removed from the machine at any time;

(3) Sealing, requiring anti-leakage, dust-proof, anti-condensation;

(4) Anti-corrosion and anti-rust, requiring protection of the friction surface from oil deterioration or external erosion;

(5) Purging and flushing require that the frictional area be cleaned and eliminated;

(6) Stress dispersion buffering, dispersing load and mitigation of impact and shock absorption;

(7) Kinetic energy transmission, hydraulic system, remote control motor and frictionless variable speed transmission.
