← TechnologyWhich outcome occurs within a liquid-ring vacuum pump when excessive gas dissolved within it cavitates?
A)Increased impeller erosion✓
B)Decreased sealing efficiency
C)Elevated discharge temperature
D)Reduced pump vibration
💡 Explanation
Increased impeller erosion occurs because cavitation induces bubble implosions near the metal surfaces, resulting in material fatigue therefore erosion, rather than temperature increases, since heat capacity limits heating significantly under these failure rate conditions.
