Uses and classifications of industrial lubricants

The lubricating oil industry is an important part of the petrochemical industry, and its development is closely related to the country's macroeconomic situation and the development of transportation, machinery and equipment and other industries. The lubricating oil industry is an industry with intensive technology, complex production and many sales links. It is one of the largest industrial chains in the world.

Industrial lubricants mainly include hydraulic oil, gear oil, turbine oil, compressor oil, refrigeration oil, transformer oil, vacuum pump oil, bearing oil, metal processing oil (liquid), anti-rust grease, cylinder oil, heat treatment oil and heat transfer oil, etc. . In addition, there are also greases with lubricating oil as base oil and thickener added. Users of industrial lubricants are companies from all walks of life. Generally, there are many varieties and large quantities used, which not only depends on the price of the product, but also depends on the quality and technical characteristics of the product, and also depends on the quality of technical services.

According to the purpose, industrial equipment lubricants can be divided into ordinary industrial lubricants, special oils and special oils. Ordinary industrial lubricants are used for machinery without special requirements, low operating temperature and load, and relatively mild working conditions. Such as machine tool transmission machinery, textile.

Machinery, construction-road, mining, transportation, metallurgy, mining machinery and equipment for other industrial sectors. Ordinary industrial lubricants usually do not contain additives. There are no special requirements for ordinary industrial lubricants except for lubrication ability, which mainly depends on viscosity and anti-aging properties. The latter is related to the quality of raw materials and the manufacturing process.

With the improvement of the quality of domestic lubricants, some companies have established good brands, and the market of domestic industrial lubricants has gradually been stabilized. At present, many companies in our country have entered the high-end lubricant product market, with the two major groups The market share of lubricating oil companies headed by Lubricant has gradually increased in high-end products.

Quality Classification of Industrial Gear Oil Industrial gear oil used to lubricate positive, helical, herringbone, bevel gears and worm gears can be classified according to quality, as follows:

1. CKB anti-oxidation and anti-rust gear oil is an ordinary industrial gear oil. It is formulated from refined mineral oil with anti-oxidation and anti-rust additives. It has strict anti-oxidation, anti-rust, anti-foam and anti-emulsification performance requirements and is suitable for general use. Lubrication of lightly loaded gears. The corresponding foreign standards are AGMAR and O type;

2. CKD extreme pressure gear oil is a heavy-duty industrial gear oil. It is formulated from refined mineral oil with anti-oxidation, anti-rust and extreme pressure anti-wear agents. It has better anti-wear and thermal oxidation stability than CKC and is suitable for Lubrication of heavily loaded gears operating at high temperatures. The corresponding foreign standards are AGMA250.04EP and U.S. Steel 224;

3. CKC extreme pressure gear oil is a medium-load industrial gear oil. It is formulated from refined mineral oil with antioxidant, anti-casting, and extreme pressure anti-wear agents. It has better wear resistance than CKB and is suitable for medium-load gears. lubricating. The corresponding foreign standard is AGMA250.03EP;

4. CKE worm gear oil Turbine worm oil is prepared by adding refined mineral oil or synthetic hydrocarbons with oily agents. It has good lubrication properties and anti-oxidation and anti-rust properties, and is suitable for the lubrication of worm gears. The corresponding foreign standard is AGMA 250.03 COMP oil;

5. CKS synthetic hydrocarbon oil, synthetic hydrocarbon oil and gear oil. Synthetic oil or semi-synthetic oil is used as the base oil with various compatible additives added. It is suitable for gear transmission lubrication at low temperature, high temperature or large temperature changes, chemical resistance and other special occasions.

6. CKT synthetic hydrocarbon extreme pressure gear oil is a low temperature and medium load industrial gear oil. The base oil is made from synthetic hydrocarbons, and additives similar to CKC are added. In addition to the characteristics of CKC, it also has better low-temperature and high-temperature performance. It is suitable for the lubrication of medium-load gears in high and low temperature environments. The corresponding foreign standard is AGMA250.03 synthetic hydrocarbon oil;

7. CKH: Ordinary open gear oil is made of refined lubricating oil and antioxidant and anti-rust agent. It has good antioxidant, anti-rust properties and certain resistance. Abrasive. Suitable for lubrication of open gears and semi-enclosed gears with general loads.

8. CKM: Solvent-diluted open gear oil is prepared by adding volatile solvents to high-viscosity ordinary open gear oil or extreme pressure open gear oil. When the solvent evaporates, an oil film forms on the tooth surface, and the oil film has a certain extreme pressure performance. The Timken 0K value of the oil film strength after the solvent evaporates is not less than 200N, or the FZG gear test passes level nine or above. 9. CKJ: Extreme pressure open gear oil is made from refined lubricating oil and added with a variety of additives. It has better extreme pressure performance than CKH or FZG oil. Suitable for lubrication of open or semi-enclosed gearboxes under harsh conditions. The Timken0K value is not less than 200N, or the FZG gear test passes level nine or above.
