Vacuum pump control method in which a gas ballast valve is controlled in a manner dependent on the detected formation of condensation within the container being pumped down

摘要

Method for controlling a vacuum pump (2), whereby a control arrangement (3) determines the condensation state within the pump and a gas ballast valve is controlled dependent on the determined condensation state so that condensation formation within the pump is prevented and already formed condensation is expelled from the pump. The invention also relates to a corresponding vacuum pump system.
