FAQ：

Q: Mistakenly believe that the greater the viscosity of lubricating oil, the better the lubrication effect

Viscosity is the main indicator of lubricating oil, and its standard is usually determined at a temperature of 100°C to determine the grade of lubricating oil. The higher the grade, the thicker the lubricating oil film formed. Although the friction on the friction surface is reduced, the resistance is increased, the power loss is increased, and the waste of energy is increased.

When the machine is just started, the temperature is low. After working for a period of time, part of the lubricating oil on the friction surface is lost due to the increase in temperature. The lubrication cannot form an effective lubricating oil film, and the oil cannot be quickly replenished to the friction surface of the machine. Due to the high viscosity of the oil, the flow is slow, resulting in greater wear of the machine parts.

Some data show that if the viscosity of lubricating oil is reduced by 1mm2/s, 15% of fuel can be saved. The choice of viscosity should consider factors such as working speed and working temperature. Lowering the viscosity of lubricating oil is one of the current fuel-saving measures.
Q: What is the phenomenon of industrial gear oil deterioration?

① Appearance changes. The color becomes darker and mixed, and emulsification occurs with obvious abrasive particles, mechanical impurities and sludge;

②Viscosity changes. The viscosity of oil containing viscosity index improver decreases due to mechanical shear, while the viscosity increases due to oil oxidation and emulsified sludge;

③Changes in acid value. In oils containing high acid value additives, the decrease in acid value in the early stages of use indicates the consumption of the additives and the increase in acid value in the later period is the result of oxidation to produce acidic products;

④ As the water content increases, the anti-emulsification performance becomes worse, and the hydrolysis of the extreme pressure agent affects lubrication and tooth surface pitting and gluing may occur;

⑤ The insoluble matter of phenylpentane (petroleum ether) increases, which is the result of contamination caused by oxidation products and metal shavings and dust at high temperatures during long-term use of the oil.
