Lubricants reduce the friction between two surfaces by keeping moving pieces apart by forming a physical barrier. This separation decreases friction, reduces wear and tear, vibrations, and noises. The use of lubricants can also help prevent corrosion, remove contaminants, seal gasses, reduce heat in a system.
The friction between a lubricant and a surface is typically much less than that between two surfaces. Overall friction is reduced when lubrication is used, such as industrial lubricant Richmond VA and others which can also result in improved efficiency.
Lubricants reduce wear by keeping the moving pieces apart. They can also have extreme pressure or anti-wear additives to help improve protection against fatigue and wear.
Other lubricant additives are used to form a moisture barrier or chemical bonds with surfaces to prevent rust and corrosion. This helps prevent corrosion between two metallic surfaces and keeps them from touching, which helps circumvent immersed corrosion.
Filters are a common component of a system with lubricants. Because of the way lubricants circulate through the system, contaminants and other debris can be carried away to a filter for removal.
Gasses can be sealed off with the use of lubricants. This is because the lubricant, through capillary force, occupies the space between moving parts witches seals for gasses.
Heat transfer can be accomplished with both liquid and gas lubricants, but liquids have a high specific heat capacity which is more effective. Because the liquid form is continually circulating through cooler parts of the system, it is more efficient at transferring excess heat.
Lubricants perform many functions in addition to reducing friction between moving parts. The additional benefits help keep the system running smoothly, without excess heat, contaminants, gasses, and while protecting against corrosion and excess wear or material fatigue.
