Do you know that lubricating oil can save energy

Engine oil, engine blood. It shows its importance. However, some of the performance of engine oil will still be ignored. For example, many people don't know if engine oil can save energy? The answer is yes.

　　 The parts of the entire engine are rubbing against each other during operation. The function of engine oil is to avoid direct dry friction between components. Friction not only causes engine wear, but friction creates resistance. If there is no lubrication, the engine will not only wear, but also the resistance generated by friction will consume more operating energy.

　　 We often neglect the lubrication of the engine, and do not even know how to use the engine oil correctly, or the relationship between it and energy saving.

　　The embodiment of lubricating oil in energy saving

　　 Next, we use simple physics principles to understand the role of lubricants in energy saving. When we consume fuel and electricity to drive vehicles or other industrial equipment, we convert the fuel and electricity into the kinetic energy of the equipment. If 100% of the fuel and electricity are converted into kinetic energy, that is the ideal state of z*, but it is impossible in reality. Due to friction, part of the energy is lost through friction. When working, the energy E consumed by the equipment is divided into two parts:

E=W(k)+W(f), where W(k) is the kinetic energy of equipment operation, W (f) is the energy consumed by overcoming friction during operation to overcome friction during operation W(f)=f *S, where S is the change in displacement, the friction force in the movement of the object f=μFN where is the positive pressure, μ is the friction coefficient of the contact surface, obviously, the greater the friction coefficient, the greater the friction, and more is needed Energy overcomes the frictional force, and the friction coefficient is related to the surface roughness. Through lubrication, the friction coefficient of the contact surface is reduced, so it plays a role in reducing wear and saving energy.

　　 In the 1960s, the British JostReport made calculations. For many countries, about 10% of the gross national product (GNP) is consumed on how to overcome friction. A large number of equipment malfunctions or even scraps due to wear. JostReport also made an estimate at the same time, through the scientific application of tribology, 1.3% to 1.6% of GNP can be saved, and the scientific application of tribology includes the use of suitable lubricating oil (motor oil) in practice.

　　 The relationship between the choice of lubricating oil (oil) and energy saving

　　 Obviously, lubricating oil can reduce the roughness of the friction surface, but lubricating oil is a chemical product with complex composition. Let’s take a look at what the composition of lubricating oil is:

　　Lubricant: base oil + additives;

　　 Grease: base oil + thickener + additive

　　 Among them, base oil can be divided into mineral oil and synthetic oil.

　　Mineral oil is divided into Type I oil and Type II oil.

　　 There are many kinds of synthetic oils, the common ones are: Class III oil, PAO/SHC, GTL, PIB, PAG, ester oil (diester, polyester oil POE,), silicone oil, PFPE.

There are more types of additives. Take engine oil as an example, including detergents, dispersants, anti-wear agents, antioxidants, rust inhibitors, viscosity index improvers, anti-foaming agents, etc., and different manufacturers also have different types of additives. There are many different types, such as viscosity index improvers. It can be seen that lubricating oil is not as simple as we thought. Due to the complex chemical composition, the gap in composition and formulation technology will lead to differences in the performance of lubricating oil. Therefore, the quality of lubricating oil is different. It is not just a matter of using it casually. We need to choose with a critical eye. High-quality lubricants can not only resist wear and prevent equipment wear, but also help energy-saving to a certain extent.

　　Lubricating oil only accounts for 1%~3% of the total equipment maintenance expenditure

The investment in lubricating oil is only about 1% to 3% of the total investment in maintenance costs. The impact of 1% to 3% is related to many aspects: the long-term service life of the equipment, the failure rate, and the failure rate affect the shutdown and productivity, and the corresponding Maintenance expenditure, energy consumption and other issues. Lubrication problems not only cause damage to components, but also increase maintenance expenses. In addition, downtime or equipment failures caused by failures, or unstable operation, will cause loss of materials and products. Therefore, a good investment of 1% can help car owners or companies save production-related Other equipment, employees, energy consumption, maintenance costs and material expenditures.
