Abstract

Una bomba comprende un alojamiento (141) que tiene una cavidad (142) con una válvula de entrada (143), un aparato (144) que eleva la presión de fluido en la cavidad (142) y una válvula de descarga (145), la válvula de descarga (145) comprende una cabeza de válvula (160) que puede moverse entre una posición abierta y una posición cerrada y un asiento de válvula (167), en donde la bomba comprende además un pistón de aumento de presión (182) colocado en un cilindro de aumento de presión (183), el pistón de aumento de presión (182) tiene una primera cara (191) expuesta a una zona de baja presión (189) y una segunda cara (194) expuesta a la presión de fluido en la cavidad (142), y al menos uno del pistón de aumento de presión (182) y el cilindro de aumento de presión (183) pueden moverse entre sí para agregar una fuerza de abertura a la válvula de descarga. De preferencia, la bomba es una bomba para fangos para la circulación del lodo de perforación a través de una columna de sondeo en un pozo o una bomba de cemento que podría ser del tipo para el bombeo de cemento dentro de un pozo. También se describe un método que facilita la abertura de una válvula que comprende una cabeza de válvula (160) y un asiento de válvula (167), la cabeza de válvula (160) puede moverse una distancia predeterminada de una posición cerrada en el asiento de válvula (167) a una posición totalmente abierta distante del asiento de válvula, y el método comprende la etapa de adición de una fuerza a la cabeza de válvula (160) a lo largo de una porción pequeña de la distancia predeterminada.
