The Basics and Importance of Industrial lubricants
Many people strongly believe that a lubricant is basically used to make things “slippery” and “smooth”. Lubrication reduces friction between moving parts by substituting fluid friction for solid friction. Without lubrication, it is difficult to move a hundred-pound weight across a rough surface; with lubrication and with proper attention to the design of bearing surfaces, it is possible to move a million-pound load with a motor that is small enough to be held in the hand.
By reducing friction, thereby reducing the amount that is dissipated as heat, lubrication reduces the amount of energy required to perform mechanical actions and also reduces the amount of energy that is dissipated as heat.
In addition to friction reduction, it also lessens the amount of wear that occurs during operation, lessens operating temperatures, reduces corrosion of metal surfaces and assists in keeping contaminants out of the system
Lubrication is a matter of vital importance throughout the industry. Industrial Lubricants are no less than any other important material or task held in the industries. Industrial Lubricants must be maintained at specific standards of purity and designed pressures and temperatures must be maintained in the lubrication systems. Without adequate lubrication, machinery will not function properly and that could lead to complete machine failure or break down.
All industrial lubricants include base oil. There are three types: Mineral, synthetic and vegetable. In lube oil industry we usually deal with mineral and synthetic. So we will focus more on these two types. Mineral oil comes from crude oil and the quality depends on their refining process.
Mineral oil has mainly two types: Paraffinic, Naphthenic. The paraffinic base oils are prepared by solvent separation techniques from paraffinic crude oil, which give good yield of high viscosity index stocks containing a lot of wax. Paraffinic have good thermal and oxidative stability and high-temperature viscosity characteristics. The naphthenic base oils derived from naphthenic crude are very available and very inexpensive. They yield medium viscosity index and low viscosity index base oils with very little wax and naturally low pour points.
Synthetic oils are man-made fluids that have similar straight chained structures much like the branched paraffinic oils. One of the advantages of a synthetic is that the molecular size and weight remains constant while mineral oils vary greatly. Therefore, the characteristics are very predictable.
Industrial lubricants are basically defined as compounds like fluids, greases and oils. They are used in order to lessen wear and tear of materials while reducing binding and friction. Industrial lubricants are reliable because they have the capacity to provide heat stability and they do not breakdown even at the highest temperature ranges. From gear oils to greases, the standard and high performance lubricants can help the necessary equipment to run smoothly, even in the most difficult environments, and for long periods of time insuring the quality, sustainability and giving you improved reliability.
A hydraulic fluid or hydraulic liquid is the medium by which power is transferred in hydraulic machinery. Common hydraulic fluids are based on mineral oil or water. The equipment that might use hydraulic fluids are excavators and backhoes, hydraulic brakes, power steering systems, transmissions, garbage trucks, aircraft flight control systems, lifts, and industrial machinery.
Hydraulic systems like the ones mentioned above will work most efficiently if the hydraulic fluid used has zero compressibility.
Brake fluid is a type of hydraulic fluid used in hydraulic brake and hydraulic clutch applications in automobiles, motorcycles, light trucks, and some bicycles. It is used to transfer force into pressure, and to amplify braking force. It works because liquids are not appreciably compressible.
Most brake fluids used today are glycol-ether based, but mineral oil (Citroën/Rolls-Royce liquid hydraulique mineral (LHM)) and silicone-based (DOT 5) fluids are also available.
Motor oil, engine oil, or engine lubricant is used for lubrication of internal combustion engines. The main function of motor oil is to reduce friction and wear on moving parts and to clean the engine from sludge (one of the functions of dispersants) and varnish (detergents).
It also neutralizes acids that originate from fuel and from oxidation of the lubricant (detergents), improves sealing of piston rings, and cools the engine by carrying heat away from moving parts.
