Researching On Vapor Ejecting Pump Vacuum System For Tobacco Humidity

Vacuum condi tioning plant is one of important equipments in threshing& redrying line and cutting thread 1 ine. The principa1 componentaffecting and determining capabi1ity of Vacuum conditioning p1ant isvapor ejecting pump vacuum system. Vapor ejecting pump is an optimaImethod for Vacuum conditioning plant acquiring vacuum.Thi s paper mai nl y analyzes the characteri st i c curve of vapor eject ingpump vacuum system, and sums up a11 kinds of factors affectingcharacteri stic curve. At 1ast, basing on the ana1ysis of experimentaldate and work practice, it puts forward a new type equipment of vaporejecting pump vacuum system, which is used for tobacco humidity.Second1y, this thesis a1so contrasts and conc1udes on a11 kinds ofmethods designing vaPor ejecting pump, and points out that Vege1inermethod is a simple but practica1 method on designing vapor ejecting pumpvacuum system.
