Knowledge of industrial lubricants

Industrial lubricants in different applications, the additives are not the same. Outdoor hydraulic oil suitable for local temperature changes, it can not be used indoor hydraulic environment closed environment. In addition, like heavy-duty gear oils and molding oil using conditions are different, heavy-duty gear oils contain extreme pressure additives to ensure that you can use in harsh environments, forming oil, usually pure mineral oil, without additives.

Various industrial oils

Statoil lubricant

Under the Norwegian state Statoil oil, its products and technology originated in 1896. With more than 650 products, including all mineral oil lubricants and fully synthetic lubricants, Statoil lubricants are used in the automotive, industrial and marine industries and cover all lubrication applications. Statoil has facilities in three countries, Norway, Sweden and Poland, nine branch offices in the Nordic countries, 25 countries and more than 10% of the products are eco-friendly (EAL's).

Various mechanical equipment due to different design and working conditions, the grease made different requirements.

The basic requirements of the selection of lubricating grease is as follows, for user reference.

1.1 quality requirements

The purpose of lubrication is to reduce friction and reduce wear. Lubricant lubrication can also take away the heat generated by friction, thereby reducing the friction surface temperature, play a cooling effect. Therefore, the operating conditions of machinery and equipment must be based on the selection of different quality requirements of lubricating grease. For example, for different compression ratio of gasoline engine, you should choose the appropriate level of quality gasoline engine oil. It is precisely because of changes in gasoline engines, it led to the upgrading of gasoline engine oil.

When selecting a lubricant for a mechanical part, the lubrication system needs to be considered at the same time. Circulating lubrication system in particular, the choice of oxidation stability and excellent anti-emulsifying oil, to ensure its service life, and easy to separate moisture and remove mechanical impurities.

1.2 lubrication requirements

Car engine operation, due to the friction parts prone to sludge, coking and coke, you must require the addition of detergent oil dispersions and other additives, but also to clean the main dispersant.

Industrial machinery and equipment due to the requirements of circular lubrication system can quickly separate the water molecules and sedimentation impurities, it is not appropriate to add detergent in the industrial lubricants dispersant.

For the lubrication of high-load parts, the boundary friction may often occur, require the use of anti-wear additives and extreme pressure agent added lubricant.

1.3 lubricant or grease selection

Lubricating oil can generally form the fluid lubrication, so that the two friction surfaces of the friction pair are completely separated by the oil film to reduce the friction of the friction surface and reduce the wear and tear. At the same time, Suzhou industrial lubricating oil has the function of cooling and cooling. Therefore, the lubricating oil is lubricated by mechanical equipment Preferred.

Grease adheres very well to the surface of the frictional parts of machinery and equipment and is not easily lost and slipping off, especially when heat or mechanical action becomes smaller or even disappears, and the grease gradually thickens and returns to a certain consistency , So the choice of grease lubrication do not often need to add, and has a protective effect, can be applied to some conditions. Such as higher or lower temperature, heavy load and shock load, medium or low speed, often intermittent or reciprocating motion bearings, especially in the vertical position of the mechanical equipment. At the same time, as the grease film is thicker than the lubricating oil film, air, moisture, dirt and debris are prevented from entering the surface of the friction member.

1.4 viscosity of choice

The viscosity of a lubricant is a fundamental factor in forming a lubricant film. In the speed, load and temperature conditions are not too high, the choice of medium viscosity lubricants. In the heavy load, low speed and high temperature conditions, the choice of high-viscosity lubricating oil or extreme pressure anti-wear lubricant. In low load, high speed and low temperature conditions, the choice of low viscosity lubricants.

In the use of wide temperature range, light load and high speed, as well as other special requirements of the operating conditions, the choice of synthetic lubricants.

The internal combustion engine oil, for example, the choice of a suitable viscosity and high viscosity index, so that both oil has sufficient high temperature viscosity to ensure that the engine lubrication and sealing operation, but also has low enough viscosity to ensure low-temperature start-up performance .
