Beschichtete Pumpen-Baugruppe |
摘要 |
A roots blower pump ( 10 ) has its internal gaps between relatively moving parts reduced by adding a liquid coating to the intake of the pump while operating the pump. The liquid coating cures to a solid surface on the moving parts, presenting opposing relatively moving surfaces that mate with one another to reduce leakage losses. |
