← TechnologyIn a hydraulic elevator lacking precise leveling, which consequence occurs during frequent short trips?
A)Accumulator pressure stratification increases rapidly✓
B)Check valve chatter causes energy loss
C)Hydraulic fluid viscosity increases sharply
D)Cylinder seal wear becomes exponentially higher
💡 Explanation
Frequent short elevator trips without proper leveling result in accumulator pressure stratification because the mixing provided by full-stroke cycles is absent; therefore temperature imbalances within the accumulator worsen which exacerbates the stratification rather than stabilizing.
