What is the reason for the emulsification phenomenon of lubricating oil in WPA100-1:30 worm gear reducer

The emulsification of lubricating oil in WPA100-1:30 worm gear reducer is mainly due to the combined effects of water content, emulsifier, and external conditions. The following are specific reasons and corresponding judgment methods:

1、 Water intrusion

External moisture ingress: In humid environments or rainy or snowy weather, water vapor enters the fuel tank through breathing caps and seals.

Internal moisture accumulation: Cooling system leakage (such as hydraulic system cooler damage) causes cooling water to mix with lubricating oil.

Process introduction: In metal processing, cleaning and other processes, water-based cutting fluid and cleaning fluid may mix into lubricating oil through surface residues or equipment gaps.

2、 Emulsifier exists

The composition of the oil itself: Emulsifying additives added to lubricating oil can enhance the emulsification tendency of the oil if the formula ratio is imbalanced or mixed with other oils.

External pollutants: Metal debris and dust generated during metal processing, as well as metal powder generated by equipment wear, will act as solid emulsifiers; Surfactants in cutting fluids and acidic substances produced by oil oxidation can also promote emulsification reactions.

3、 External conditions

Mechanical stirring: When the equipment is running, the high-speed rotation of components such as gears and bearings will strongly stir the oil, dispersing water into small droplets that are evenly suspended in the oil, forming a stable emulsion.

Temperature changes: Frequent temperature fluctuations can disrupt the viscosity balance of the oil. At low temperatures, the viscosity of the oil increases, making it difficult for moisture to settle; High temperature accelerates oil oxidation, producing more polar substances and enhancing emulsification ability.

4、 Other reasons

Poor oil quality: Using poor quality lubricating oil or using lubricating oil for too long, resulting in changes in oil performance indicators.

Equipment malfunction: The clearance between the piston rings of the air compressor is too large, the cooler collects too much water (water enters the cylinder and flows into the body with compressed air, causing oil emulsification), and the air filter is blocked (obstructing the normal circulation of oil, causing internal pressure and temperature to rise, thereby damaging oil function).

5、 Judgment method

Observation method: The significant phenomena after lubricating oil emulsification include: at the observation window of the compressor lubricating oil level, the lubricating oil appears milky white or yellow white, and there are impurities in the oil
