← ScienceWhich risk increases as the lubrication pump's clearance widens?
A)Increased cavitation erosion of the bearing
B)Reduced hydrodynamic wedge film formation✓
C)Elevated oil oxidation from pressure
D)Accelerated lubricant thermal decomposition rates
💡 Explanation
As the pump's clearance widens, volumetric efficiency decreases, thinning the oil film, because the viscous drag forces are weakened because lubricant cannot properly undergo viscous adhesion; therefore, reduced wedge results, rather than other modes of thermal or oxidative degradation.
