Download E-books Die Kreiselpumpen für Flüssigkeiten und Gase: Wasserpumpen, Ventilatoren, Turbogebläse Turbokompressoren (German Edition) PDF

By Carl Pfleiderer

Pumpen sind Vorrichtungen zum Fordern von Flussigkeiten und Gasen. Ihre haufige Anwendung beruht darauf, daB Flussigkeiten sich in Rohrleitungen am wirtschaftlichsten fortbewegen lassen. In die be treffende Rohrleitung, die den Ausgangspunkt mit dem Bestimmungsort verbindet, wird die ortsfeste Pumpe eingeschaltet, damit sie auf die Flussigkeit die zu ihrer ]'ortbewegung notigen Krafte ausubt, namlich auf der einen Seite saugend, auf der anderen druckend wirkt. Sie ver ursacht dadurch eine Drucksteigerung in der Rohrleitung auf der Aus tritt. sseite der Pumpe (Druckstutzen) und eine Drucksenkung auf der Eintrittsseite in die Pumpe (Saugstutzen). Demnach muB als Zweck der Purnpe im weitesten Sinn, wenn guy ihre Wirkung getrennt von der Rohrleitung betrachtet, bezeichnet werden, flUssige oder gasforrnige Kor-per aus einern Raurn rnit niederer Spannung in einen Raurn rnit hOherer Spanmmg zu befordern. Hier liegt offen bar der umgekehrte Vorgang vor wie bei den Kraft maschinen, mit denen die Pump en auch hinsichtlich ihres Aufbaus weit gehende Ahnlichkeit besitzen. Wie dort unterscheidet guy auch hier zwei groBe Hauptgruppen, namlich: 1. Die Kolbenpurnpen als Umkehrung der (allerdings nicht mehr in Gebrauch befindlichen) Wassersaulenmaschinen bzw. der Kolben dampfmaschinen. Das Kennzeichen ist hier der im geschlossenen zylin drischen GefaB hin und her gehende Kolben, der die Pressungsenergie des Fordermittels durch statische Kriiftewirkung erzeugt. 2. Die Kreiselpurnpen als Umkehrung der Turbinen. Zu diesen beiden wichtigsten Ausfiihrungsformen gesellen sich einige weitere von untergeordneter Bedeutung, bei welchen Antriebsmaschine und Pumpe gewissermaBen vereinigt sind und welche deshalb bei den Kraftmaschinen keinen entsprechenden Vertreter haben, wie Strahl pumpen, Widder, Mammutpumpen usw.

Download E-books Stimulus-Response Compatibility Principles: Data, Theory, and Application PDF

By Robert W. Proctor

Knowing of the standards that impression stimulus-response (S-R) compatibility and make sure whilst and the way compatibility results will come up is an important beginning for properly using compatibility rules in layout and for comparing the relative compatibility of different designs. Summarizing the country of latest wisdom concerning determinants of compatibility, Stimulus-Response Compatibility rules: facts, thought, and alertness presents thorough, up to date insurance of uncomplicated and utilized learn coupled with an emphasis on pertaining to this data to precise layout guidelines.

Examining a wide diversity of theoretical and utilized matters from the compatibility standpoint, the authors assessment simple examine dedicated to theoretical concerns relating S-R compatibility particularly and the relation among notion and motion extra regularly. They hide results of alternative S-R mappings in easy and intricate projects, components that impact response-selection potency, correspondence results of beside the point stimulus info, compatibility results for a number of and orthogonal dimensions, outcomes of combining mappings and initiatives, perform and move results, compatibility results in multiple-task functionality, and path of movement stereotypes. The authors offer an intensive therapy of other perspectives, contrasting and evaluating their strengths and weaknesses. they supply directions that comprise present wisdom approximately compatibility effects.

Previous books on S-R compatibility were edited works that contained distinct descriptions of the findings of varied study courses internationally. hence, these books don't offer a cohesive evaluate of the diversity of analysis on compatibility results, and the remedies they supply aren't effortless to realize through people who lack a historical past within the region. Making details available to a large variety of researchers and practitioners, this article organizes, summarizes, and integrates the giant quantity of information relating S-R compatibility.
