The difference in lubrication effects of synthetic oil and mineral oil on ZQ400-25 reducer under high humidity environment

Synthetic oil: Synthetic oil has been chemically synthesized, with a more neat molecular structure and excellent antioxidant properties. In high humidity environment, its oxidation resistance is strong, it can effectively resist the oxidation effect of moisture and oxygen on oil products, reduce the formation of harmful substances such as sludge and carbon deposits, extend the service life of lubricating oil, and maintain a good lubricating effect.

Mineral oil: Mineral oil is a natural oil extracted from petroleum and has relatively low oxidative stability. In an environment with high humidity and oxygen, oxidation reactions are prone to occur, resulting in acidic substances and colloids, which accelerate the aging and deterioration of the oil, affect the lubricating performance, and may also cause corrosion to the internal components of the reducer.

Synthetic oil: Synthetic oils usually have good anti-emulsification properties, which can quickly separate the moisture mixed into the oil, making it difficult to form a stable emulsion. This helps to maintain the purity and lubricating performance of the lubricating oil, and avoids problems such as reduced oil film strength and poor lubricating effect due to emulsification.

Mineral oil: Mineral oil has relatively weak anti-emulsification properties in high humidity environments. When moisture enters, it is easier to form an emulsifier. Emulsified mineral oil will damage the continuity and strength of the oil film, reduce the lubrication effect, and increase the wear risk of components such as gears and bearings.

Synthetic oil: Some synthetic oils will add efficient anti-rust additives, which can form a firm protective film on the surface of metal parts of the reducer in high humidity environments, effectively preventing moisture and oxygen from contacting metal, preventing rust and corrosion, and protecting metal parts inside the equipment.

Mineral oil: Although mineral oil can also add anti-rust additives, the overall anti-rust performance is often not as good as synthetic oils. In high humidity environments, the protective film formed by mineral oil is relatively weak, and moisture is prone to permeation, which increases the possibility of metal parts rust.

Synthetic oil: Synthetic oil has good low-temperature fluidity. When accompanied by low temperature in high humidity environments, it can still maintain good fluidity, quickly reach all lubricating parts of the reducer, form an effective oil film in a timely manner, reduce start-up wear, and ensure the normal operation of the equipment at low temperatures.

Mineral oil: The fluidity of mineral oil at low temperatures is relatively poor. Under low temperature conditions in high humidity environments, viscosity may increase or even solidify, affecting the transportation and distribution of lubricating oil, resulting in untimely lubrication, increasing the difficulty of starting equipment and wear.
