Mechanical impurities refer to solid particles in oil that are insoluble in solvents, and their presence directly affects lubrication effectiveness and equipment lifespan.
The main sources of mechanical impurities are:
External pollution:
Dust, sand particles, metal shavings, etc. enter the lubrication system through poorly sealed areas.
Contaminants introduced during maintenance or refueling processes.
Internally generated:
Metal particles generated by equipment wear (such as bearing and gear wear).
Sediments such as gum and carbon deposits generated by oil oxidation.
Residual oil itself.
Impurities that are not completely filtered during the production or storage of lubricating oil.
The harmfulness of mechanical impurities:
Intensifying wear: Hard particles (such as metal shavings) can scratch the friction surface, forming a vicious cycle.
Blocked oil circuit: Accumulation of impurities may cause filter blockage, decrease in oil pressure, and insufficient oil supply.
Accelerating oil degradation: catalytic oxidation reaction of particulate matter, shortening the service life of lubricating oil.
Impact on heat dissipation: Impurity deposition affects the thermal conductivity of oil products.
