INTRODUCTION
What is basically Lubrication?
Lubrication is the process of reducing friction. Friction is the key work in understanding lubrication. Friction has been defined as the force interposed between contacting surfaces of two bodies and resists motion of one body relative to the other. Another words friction is the resistance felt when rubbing one body against another.
How is friction actually caused ? If any metal surface no matter how smooth is observed through a microscope the surface will be seen to be jagged. This the basic cause of friction. Since when two metal surfaces which slide against retarding smooth sliding action. Weak is caused when the jagged edges break off and if the edges continue to wear, deterioration of the metal surface takes place.
Lubrication is simply defined as the science of reducing friction by the instruction for suitable friction reducing substances between the rubbing surfaces of bodies having relative motion.
Lubricants dot the lubrication. These many grease oil or lubricants which provides the temporary lubrication for the maintenance industry. But it does not lubricate the machine poot. From the damage of friction and wear for a long period. This is called the ordinary oil or grease or lubricants. Ordinary lubricants have the napthanic base which cause to acid wear, frictional wear.
Supreme Tenacity
This specialized has a marked ability to follow a gear train and stay in position. This well known lubricant trait has been subject to many – mainly unuseful attempts to copy or assimilate these actions. However there is always a difference between the ‘copy’ and the genuine quality of special oil. This special lubricant retains a fine film on the metal surface regardless of how thoroughly it is wiped away. This one aspect ensures that the specialized lubricant oil is performing its special function. Ordinary gear oils migrate away from the metal surface. They leave the friction surface exposed to direct and unprotected contact. This lends itself to oxidation and oxidation causes corrosion. Corrosion is the ‘metal cancer’ of industry.
Compensatory Thermostat Action
This specialized lubricant oil contains billions of extremely sensitive, microthermostat action nitrodecafluron polymers that compensate for the natural tendencies of an oil to thin out or thicken when subjected to high and low temperature fluctuations. These polymers become expanded when the oil temperature is high and the oil is therefore thinned. They contract when the oil temperature is low, and the oil is therefore thicker. This expansion and contraction action is accomensatory action essential to the quality of the lubricant and the protection of the equipment.
Industrial and Military Characteristic
For many years, the military establishment of the world have tried and tested hundreds and thousands of different gear oils for the purpose of finding one that can meet the International Climatic Stability Requirements (ICSR). These specialized lubricant oil not only meets these requirements, but also exceeds then with a basic operating temperature range of – 3 degree Celsius to 210 degree Celsius.specialized oil tolerates both sub – arctic and Namibian Desert Climates.
Extreme Pressure
Specialized multi purpose lubricant oil is heavily fortfied with carefully calibrated, extreme pressure resistant supplements. Its additional supplements for corrosion resistance, oxidation resistance, water wash qualities and many other far outnumber those of most of ordinary gear oils. The special extreme pressure are designed to withstand such adverse performance condition as
