Engineering (industrial) lubricants are a wide range of lubricating oils that are used for various applications and purposes in industry and are usually produced for each specific feature of a specific lubricant, such as for long life or high temperature or temperature. Low or compatible with food and in working conditions inside or outside the machine, we must use a specific lubricant in each.
Therefore, for these purposes, it divides industrial oils into the following branches.
Gear oils, gearbox oils, compressor oils, turbine oils, diesel generator oils, transformer oils, circulating and hydraulic oils, agricultural machinery oils, shielding oils, and industrial heat transfer oils are classified.
Industrial gear oil:
Industrial gearboxes must operate in conditions of high heat and heavy loads, and in dusty environments, residues from work and water. Without proper care, the gears wear out prematurely. You will have to replace the parts quickly, change the gear oil more often, and worst of all, watch the equipment break down.
Industrial gearbox oil:
Gearbox oil is a lubricating fluid that lubricates the moving parts inside the gearbox. In automatic transmissions, this oil is also responsible for cooling the gearbox and transferring power from the engine to the gearbox.
Different gearboxes use different oils for lubrication. Automatic gearboxes use oils called ATF, which stands for automatic gearbox oil. For manual transmissions, however, there are different oils. From oils with similar specifications to engine oils to heavier oils for hypoid gears and in some rare cases oils similar to automatic transmissions. To find out what kind of oil your car’s manual transmission needs, you should refer to the car’s owner’s manual.
Industrial compressor oil:
VDL air compressor oil is produced for use in reciprocating (piston), helical (screw) and blade (van) compressors. Features of this oil include rapid release of air without creating foam in the system. These types of oils can be produced and supplied in 32, 46, 68, 100, 150 grades.
Industrial turbine oils:
It is a type of industrial oil that has ideal lubricating properties in gas, water and steam turbines with excellent separation of air from oil and water from oil.
Industrial diesel generator oil:
Choosing the right oil for the electric generator due to the essential role of oil in improving the life and efficiency of the electric generator on the one hand and also reducing its depreciation on the other hand are important questions for buyers and users of diesel generators. Therefore, Kashani Industrial Complex It always emphasizes to the users of power generator devices that while studying the manuals of the device, which usually offers the appropriate oil for the same model of diesel device purchased, it is necessary to use the oils produced by reputable factories according to the practical classification tables of engine oils. Use the basis of standards (API).
Industrial Transformer Oil:
It has a mineral base with electrical insulation properties and in high-power transformers, it facilitates lubrication, anti-oxidation and corrosive sulfur-free operations, cooling, and absorption of gases formed by electrical discharge.
Circulating and hydraulic oils:
These oils with excellent thermal stability for industrial machines with rotating and hydraulic systems, bearings, sprockets, closed gear systems, electric pump motors, textile machines and any tools that are anti-corrosion and anti-oxidation circulating oils. Need.
Hydraulic oil category:
Hydraulic oil, like other oils, is a mixture of “base oil” and additives. Depending on the type of base oil and additives, it can have different applications in different systems.
Hydraulic oil can be called the most widely used industrial oil, and therefore, due to its high consumption and various applications and various working conditions, this oil also has a high diversity. In fact, hydraulic oil plays the role of an energy transmitter in a system, and if this oil has a problem, this task is not performed well and the system encounters a malfunction or stop in operation.
In general, hydraulic oils are divided into the following quality levels according to ISO 6743:
1- HH: Mineral base oil without additives: This was the first generation of hydraulic oils
2- HL: By adding anti-corrosion and anti-oxidation additives, a new generation of these oils was created, which is also called rotary oils.
3- HM: By adding anti-wear additives to HL oils, new hydraulic oils were produced, which are currently the most widely used hydraulic oils.
4- HV: By increasing the viscosity index of HM hydraulic oils, this level of quality was obtained, which is suitable for operation in a wide temperature range.
5- HG: These oils, which are known as machine tool hydraulic oils, due to their adhesive properties, are not thrown out of the system in reciprocating sliding systems.
This classification of quality levels is one of the most famous classifications of hydraulic oils. But other standards are also defined in hydraulic oils, which can be called the following standards
DIN 51524, Cetop RP 91 H, Afnor NFE, Cincinati Milacron,…
In general, the tasks expected of a hydraulic oil are lubrication, transmission, reduction of friction and wear, protection against rust of system components and compatibility with all system components.
Another category is hydraulic oils, known as fire-retardant hydraulic fluid oils. Of course, this does not mean that these fluids do not ignite in the presence of fire, but they ignite later in the presence of fire and resist the emission of flame. These oils are commonly used in places where there is a high risk of fire (such as metal smelting furnace doors).
These oils are also divided into four main categories
1- HFA: Oil emulsions in water
2- HFB: water emulsion in oil
3- HFC: Glycol water fluids
4- HFD: Kinetic fluids
Required and sensitive information about hydraulic oils:
One thing to keep in mind when working with hydraulic oils is that hydraulic oils, such as turbine oils, are highly sensitive to the contaminants that enter them, and their physical and chemical properties are affected by contamination and hardening conditions. He will have trouble with oil. Also, when choosing an oil for the hydraulic system, using the advice of lubrication experts, choose the right oil and increase its life by observing the practical points for consumption, change, overflow and most importantly, condition monitoring (CM) of the oil. Help the health of the equipment and finally we can achieve the desired result of reducing lubrication costs.
Industrial Agricultural Machinery Oil:
One of the major events that occur when using lubricants and drastically reducing their life and performance is the accidental mixing of different types of lubricants. One of the most common occurrences is the mixing of hydraulic oil and engine oil in heavy road construction and agricultural vehicles. The solution chosen to solve this problem in heavy road construction machinery was to produce hydraulic oil from engine oil. Equipment should be provided that can perform gear oil, motor and hydraulic work for the vehicle at the same time.
Industrial protective oils:
To protect the surfaces of steel sheets, it is resistant to rust, which is produced by using mineral base oils and suitable additives. This oil is recommended to cover the surface of hot rolled steel sheets that are acid-washable, as well as cold steel sheets (Cold Rolled) after wet or dry pass scans.
Industrial heat transfer oils:
It has been produced by using high quality paraffinic base oil obtained from shear refining of crude oil and refining process with hydrogen (Full Hydrofinishing). The base oil of this product has been separated and selected in such a way that the required specifications, especially in terms of non-creation. It does not supply oil vapor to the system.
