Title
(EN) ELECTRIC POWERED DIAPHRAGM INK PUMP APPARATUS AND METHOD
(FR) APPAREIL ET MÉTHODE DE POMPE À ENCRE À DIAPHRAGME À ALIMENTATION ÉLECTRIQUE
Abstract
(EN)
An electrically powered and electronically controlled diaphragm ink pump apparatus (e.g., 100, 200 or 300) and method for synchronous pressurization of ink in a corrugated board sheet feeding system comprises a diaphragm pump assembly including a reciprocating electrically driven crank mechanism connected to and driving first and second diaphragms or diaphragm surfaces, each diaphragm or diaphragm surface housed within a pump housing (e.g., 140, 240 or 340) having an ink inlet and an ink outlet in fluid communication with a manifold configured for pumping liquid ink to printing sections of a corrugated paperboard finishing machine 10 and provide a smooth reciprocating action and more uniform ink flow with reduced pressure pulsations.
(FR)
Un appareil de pompe à encre à diaphragme commandé électriquement et controlé électroniquement (par exemple 100, 200 ou300) et un procédé de mise sous pression synchrone d'encre dans un système d'alimentation en feuilles de carton ondulé comprend un ensemble de pompe à membrane comprenant un mécanisme de manivelle alternatif entraîné électriquement en va-et-vient entraînant des premier et second diaphragmes ou des surfaces de diaphragme, chaque diaphragme ou surface de diaphragme étant logé à l'intérieur dans un boîtier de pompe (par exemple 140, 240 ou340) ayant une entrée d'encre et une sortie d'encre en contact fluidique avec un collecteur configuré pour pomper de l'encre liquide vers des sections d'impression d'une machine de finition de carton ondulé 10 et fournir un mouvement alternatif doux et un flux d'encre plus uniforme avec des pulsations de pression réduites.
