← TechnologyWhich failure occurs in cryogenic pumps because dissolved atmospheric gases precipitate?
A)Vapor lock induced cavitation✓
B)Mechanical seal face fracturing
C)Excessive oil cooler fouling
D)Progressive impeller blade erosion
💡 Explanation
Vapor lock induced cavitation occurs; dissolved gases exiting solution form bubbles that then collapse with great force on the metal. This occurs because lowered vapor pressure decreases gas solubility therefore cavitation, rather than the other mechanical failures, is most immediate.
