            Whats the matter with the vacuum furnace not pumping clean air

            What's the matter with the vacuum furnace not pumping clean air?
            In normal tests, if there is liquid, it needs a process of liquid evaporation (it can be vaporized without heating under high vacuum). This part of liquid can be vaporized by pulling vacuum for a long time to achieve high vacuum (etc. stability)
            If the target air pressure cannot be reached for a long time, the system and roots pump should be considered. You can directly measure the limit vacuum of roots pump (without connecting other systems). If it is intact, it is the sealing performance of the system
