Causes of Lubricant Degradation and Daily Oil Replacement Maintenance

Causes of Lubricant Degradation and Daily Oil Replacement Maintenance

Lubricants gradually deteriorate during use due to high temperatures, water vapor, dust, and metal impurities. Common problems include emulsification of the oil, oxidation and blackening, and excessive impurities. Water-induced emulsification is often caused by damaged equipment seals; high temperatures accelerate oil oxidation and coking, and fine grinding debris continuously catalyze the deterioration of the oil.

Daily management involves taking samples for regular viscosity, moisture, and acid value tests. If the indicators exceed the standard, replace the oil promptly; ensure that the added oil is filtered to prevent mixing of different brands. When equipment is shut down for long-term storage, fill it with lubricating oil to isolate from air and prevent rust. Properly control the oil replacement cycle and abandon fixed-time oil replacement; based on the oil test data, it can save oil costs and reduce equipment failure downtime.
