Base oils are obtained by refining mineral base oil or by chemical (synthetic base oil). These oils have boiling points in the range of 550 to 1050 degrees Fahrenheit and contain hydrocarbons with 18-40 carbon atoms, these hydrocarbons can be paraffinic or naphthenic, which depends on the chemical structure of the crude oil.
Base oils are graded under different names:
- Neutral Solvent (SN)
- Bright Stock (BS)
- Neutral (N)
Given that various refining processes that are common today for the production of base oils can lead to the production of base oils with different properties, the American Petroleum Association (API) classifies base oils according to their physical properties. Chemical and their characteristics. Based on API grouping, base oils are divided into 5 general groups: API I, API II, API III, API IV, API V, each of which has sub-branches.
This group of base oils has the lowest degree of purification among other groups. In this group, the purification is usually done by solvent and the mixture after purification is formed of non-uniform hydrocarbon chains. This group is introduced as a base oil with a viscosity index between 120-180 and a sulfur level of more than 0.03%.
The products of this group are named as follows:
SN 80, SN 100, SN 150, SN 250, SN 300, SN 350, SN 400, SN 500, SN 600, SN 650, SN 700, SN 900, SN 1200, BS (Bright Stock)
This type of oil has an average property among group I oils and is mainly used in the production of lubricants and lubricant additives.
- Casting oil
- Gear oil
- Metalworking fluid
- Hydraulic oil
- Transformer oil
Transformer oil :
Electricity is one of the most central industries in the economic growth of a country and any country that seeks economic growth has a vital need for the development of the electricity industry. Distribution of electricity from one power plant to different areas requires the use of power transmission and distribution networks, which is done by power, distribution and power transformers.
There are two types of transformer insulation oil bases:
- Mineral oil from crude oil with hydrocarbon oil base (naphthenic, paraffinic)
- Synthetic oils made in the laboratory such as Ascarl, silicone, ester and …
Transformer oil has completely specific uses and a significant amount of it in the facilities of the country’s electricity industry, including oil-filled transformers, high voltage capacitors (ballast), fluorescent lamps, some high voltage switches (high voltage switches) and circuit breakers (circuit breakers) are used.
The main function of oil in equipment is as an electrical insulator and a cooling fluid.
Turbine oil :
Turbine oil is used in a rotating mechanical device, which converts heat energy into mechanical energy to generate power. In the course of the production of this force, any unforeseen disruption and stoppage will cause a lot of financial damage. Among the companies producing turbine oil, we can name Shell, Mobil, Aso, Behran, Pars, Iranol, Total, etc., which are approved by General Electric, Alstom, Siemens, ABB (which are major manufacturers of turbines). They have, he noted.
- Prevents rust and abrasion
- Proper hydraulic performance
- Lubrication of equipment, gears, bearings and couplings
- Heat transfer and cooling in bearings
The structure of turbine oil is about 97% of mineral base oil and the rest contains booster additives, so providing most of the properties of this oil is the responsibility of the base oil and should be very careful to choose the base oil used in turbine oil. .
Silicone oil :
Silicone oil is a type of liquid silicone impregnated with organic side chains. This oil is tasteless, odorless, non-toxic and non-flammable and has been welcomed in the trade due to its lubricating properties and relatively high thermal stability. The main constituents of these polymers are the variable atoms of silicon and oxygen.
- Chemical stability
- Heat resistant
- Anti-foam property
- Non-adhesive to rubber, plastic, metal and other materials
- Anti-corrosion property
- Lubricating properties
- Very low surface tension
- Good dielectric factor
- Low steam pressure
- Water repellent
Compressor oil :
The formulation of compressor oil production depends on the type of compressor and the type of compressed gas and pressure. It is very important to use suitable and specialized compressor oil in compressors. The structure of compressor oil, like other oils, consists of two main parts: base oil and additive. The main functions of compressor oil are lubrication of internal parts, cooling, sealing and prevention of corrosion and wear. Mineral-based compressor oil is suitable for normal working conditions with non-reactive gases, and synthetic-based oil is used for harsh working conditions with high temperature and pressure with gases that are reactive with mineral-based oils.
Compressor oil is selected based on the type of compressor, the type of compressor operation, the type of compressed gas and the manufacturer’s recommendation.
Compressor oils are selected based on the type of compressor, operating conditions in terms of temperature, pressure and type of gas with the following characteristics:
- Oxidation resistance
- Thermal stability
- Low carbon residue at high temperatures (high pressure reciprocating compressors)
- Compatibility with compressed gas
- Maintain viscosity (resistance to dilution with compressed gas)
- Anti-wear properties (vane rotary compressor)
- Prevent gas leakage
- General lubrication
- Heat dissipation
- Prevent corrosion
- Compatible with compressor parts
- Good demolition
- Clean and free of particles
- Low tendency to foam
- Low flammability
Car oil :
Engine oil is one of the most widely used lubricants in the market. Based on this, various standards and classifications for engine oil have been presented, which are three important references for standardization in the automotive industry and related industries:
- US API
- ACE Europe
- ILSAC Asia
Engine oils are divided into three general types:
- Mineral (organic)
- (Premium) Semi-synthetic
Hydraulic oil :
Hydraulic oil is one of the most important groups of lubricants, accounting for almost one-fifth of the lubricant market. This oil contains base oil and additives, the quality and efficiency of hydraulic oil depends on the quality of the base oil and the composition of the additives used.
Mineral base oils (paraffinic oils, naphthenic oils) are used as hydraulic oils or hydraulic base oils. Hydraulic oils based on synthetic oils (poly-alpha-olefins, ester oils and polyglycols) prepared by hydro-fracture method are mainly used as fire-retardant oils as well as biodegradable oils. In addition, vegetable oils are used as biodegradable oils.
Hydraulic oils used in the food industry are also mainly based on white oil, poly-alpha olefins and polyglycols.
Hydraulic oil is more diverse than other types of lubricants not only due to lubrication but also in the ways through which power is transmitted in the hydraulic system and in order to play the best role in this field, it needs a coefficient of accumulation, viscosity , High viscosity index and suitable additives.
Pressure and operating temperature directly affect the viscosity of the oil, so the initial choice of oil should be based on its viscosity.
The addition of these materials improves the properties of hydraulic oil such as protection against corrosion and abrasion, compressibility, viscosity behavior with temperature changes, foaming, water separation ability, coefficient of friction, cleaning and long-term stability.
The most important additives used in hydraulic oils are:
- Surfactants such as rust inhibitors, metal deactivators, anti-wear additives, friction improvers, cleaners and dispersants
- Basic oil preservatives such as oxidation inhibitors, anti-foaming additives, viscosity index improvers and drop point improvers
Grease is a gelatinous solid or semi-solid substance that consists of a base oil (mineral or synthetic oils) as a lubricant, a hardener (metal soaps, polymers and minerals) as a carrier of base oils and additives. Is.
After oils, lubricant has the highest consumption of lubricants and due to the presence of filler in it, it adheres to moving parts and does not separate from the part under gravity, centrifugal force and pressure. Therefore, they are used in places where the oils are no longer responsive, such as when the lubricant should act as a barrier to the entry of dust or exit of some materials from the machines, or the position of movement between the two surfaces is such that the lubricant is needed. Requires semi-solid such as industrial gears, large bearings, pulleys and the like. Lubricants such as oil are used to reduce friction and erosion between two moving parts to the lowest possible extent.
- Longer shelf life of lubrication (some greases are made to remain in the part as a seal and its life is the same as the part).
- Ease of use and reduction in the number of lubrications, which reduces costs and repairs.
- More complete sealing of systems, reduction of leaks and no dripping during operation
- Better adhesion
- To prevent rusting of the part, especially when a part is not used and the lubricant is removed.
- No problem of lubrication in the presence of water
- Reduce noise and vibration and smooth operation on some devices such as large gears
- Simplicity of lubrication system design
