Which outcome occurs when a scroll pump's orbiting scroll wears unevenly with pressure?

💡 Explanation

The scrolls separate, and the volumetric efficiency declines because gas leaks backward across the scroll gaps via backflow, rather than reaching the output port. Therefore, pumping efficiency diminishes; rather than increased heat or specific bearing fatigue.
