Lubrication is a very important aspect of machinery and manufacturing, and whole study disciple by the name Tribology is dedicated to it. Lubrication involves the technique and process of using a lubricant for reducing wear and friction that may occur due to contact between two different surfaces. Lubrication offers a number of benefits including lesser wear rate, increased uptime due to continuous operations, and prevention of damage to the bearings and components that may occur because of stress and seizures. It also provides for avoidance of accidents that may occur due to the heat or damages that may occur to the components on machines due to the absence of a lubricant.
Lubrication, therefore, holds immense importance and the benefits of lubrication span across various aspects of an operation of a processing system. The main purpose of lubrication is to reduce the friction and provide for smooth sliding of surfaces. Beyond a critical and given temperature, the absence of lubrication may cause the generation of immense heat that can fuse the individual components and burn them, while also causing a seizure.
Because of the immense variations in the structure, form, and functionality of the machinery around us, lubricants are also produced and used in different forms. A lubricant may be in the form of a gas (hydrogen, helium), liquid (water, oil), liquid/solid dispersion ( grease), or solid (molybdenum disulphide). Modern lubricants not only reduce friction, but they are also created to possess characteristics like corrosion and oxidation resistance, demulsibility, high viscosity, thermal and hydraulic stability, and also made to possess a low freezing temperature and high boiling temperature (so that they remain liquid across of wide range of temperature). Some of the benefits of lubrication and lubricants include:
The thickness and viscosity of a lubricant, for instance, a grease lubricant lying in-between two surfaces makes an impact on the fatigue life of the components like bearing. A thicker lubricant film will prolong the fatigue life so that the operation times increase, and vice versa.
The new industrial lubricants provide for better thermal stability and can be used in the most hazardous and dangerous of situations and processes. They preserve their structural integrity and advantageous characteristics across a wide range of temperatures. These lubricants can be used to protect machinery in the extreme heat and extreme cold environment as well.
Capture and Dissipation of Frictional Heat
Many of the machinery and processes use the circulating lubricants that capture the heat produced because of friction and transfer it subsequently to the surroundings. The feature increases the life of the bearings, provides for prevention of overheating, and makes a process more reliable.
Advanced lubricants contain the characteristics that allow them to prevent corrosion. The film that they form around the bearings or other machinery components does not allow material rusting.
Lubricants and lubrication, therefore, contribute positively towards the smooth operation and functioning of the individual machine parts and make a process successful, optimized, and more reliable. The new high-performance lubricants include within themselves many new characteristics that help industries derive the newest advantages out of these effective products and substances.
