AI Technical Summary
Technical Problem
Scroll vacuum pumps with TipSeals face issues such as limited lifespan, abrasion, sensitivity to external influences, and require precise axial gap dimensions, leading to variable vacuum performance and increased maintenance.
Method used
Implementing an adjusting means to actively or passively influence thermal expansion and heat transfer within the pump, using materials with varying thermal conductivities, heating/cooling devices, and control systems to precisely set and maintain the axial gap between spiral components.
Benefits of technology
Ensures consistent vacuum performance over time by reducing maintenance needs and minimizing the impact of external influences, while allowing for precise adjustment of the axial gap to enhance pump efficiency.
