Abstract

Invenţia se referă la construcţia de pompe, în particular la evacuatoarele pompelor dinamice.Evacuatorul conţine o cameră în formă de spirală, un canal difuzor, suprafeţele interioare ale cărora formează o limbă, precum şi un niplu conic de presiune. Noutatea invenţiei constă în aceea că suprafeţele interioare ale camerei în formă de spirală şi ale canalului difuzor care formează limba se întretaie în secţiune longitudinală într-un punct situat pe circumferinţa iniţială a spiralei camerei, totodată suprafaţa limbii din partea canalului difuzor este executată tangenţial la circumferinţa iniţială.Rezultatul invenţiei constă în reducerea pierderilor hidraulice în evacuator şi în majorarea randamentului pompei.
