Abstract

Menetelmä pyörimisnopeussäädetyn keskipakopuhaltimen automaattisen sakkaukseneston ohjaamiseksi. Olennaista keksinnössä on, että prosessin automaatiojärjestelmän avulla ohjataan säätöautomatiikkaa, jossa sakkaus tunnistetaan keskipakopuhaltimen moottorille menevän sähkövirran, jännitteen ja taajuuden funktiosta.
