Industrial Lubrication Machinery - A Practical Guide
Professionals often get very familiar with the viscosity of lubricants they use. Viscosity is the most important characteristic of a base oil. The understanding the function of additives within the lubricant is important. All lubricants start with base oils. There are three types of base oils: mineral, synthetic, and vegetable. In industrial applications, the most common ones are mineral and synthetic.
Anti-wear and extreme-pressure additives
Wear and friction control additives are the most common used packages and generally come in the form of either anti-wear (AW) or extreme-pressure (EP) additives.
Anti-wear additives are used to protect against wear and the loss of metal surfaces during lubrication. This package is triggered by temperature or elevated loads at the contact surfaces. The additives are used to protect surfaces or to eliminate them from wear.
Extreme-pressure additives are often stronger additives. This additive package is triggered through high loads although they can also be temperature and non-temperature dependant.
Engine lubrication: commonly anti-wear, anti-foam, detergents, antioxidants and and corossion inhibitors are used.
Steam turbines lubrication: commonly anti-foam, detergents, demulsifiers antioxidants and corossion inhibitors are used.
Gears lubrication: commonly anti-wear, extreme-pressure, anti-foam, antioxidants and corossion inhibitors are used.
Hydraulic systems lubrication: commonly anti-wear, extreme-pressure, pour-point depressants, anti-foam, viscosity index improvers, antioxidants and corossion inhibitors are used.
Uses of professional lubricants
Oils: Hinges, bearings, tool maintenance, sharpening blades.
Greases: Gears, bearings, chains, linkages.
Penetrating lubricants: Penetrating lubricants are thego-toes of many stuck-bolt combatants, loosening years of rust and debris in minutes.
Dry lubricants: 3D printer rails, threaded rods, locks, hinges.
Coolants: This kind of lubrication can be devided into three groups, soluble oils, synthetic fluids and semisynthetic fluids. All coolants contain additives that enhance lubricity, inhibit rust and bacteria growth, or reduce foaming; additives react favorably during machining to provide additional lubricity in the cut.
Food Safe lubrication: Food Safe lubricants are often NSF H1, H2 or H3 registered. H1 lubricants are food-grade lubricants used in food-processing environments where there is the possibility of incidental food contact. The role of these kind of lubricants are to provide protection against wear, friction, corrosion and oxidation.
