Using 7-inch liners in the pump modules, it is expected that mud pump 50 can pump mud up to 1500 pounds per square inch in pressure.

In this configuration, mud pump 50 is positioned "lengthwise" in pump house 68. Referring to Figure 13, mud pump 50 is shown in pump house 68 rotated 90 degrees. The compactness of mud pump 50 can allow it to be installed in this manner in pump house 68 whereby access to the inlet and outlet to mud pump 50 is through doorway 70. In addition, more than one mud pump 50 can be installed in pump house 68 thereby reducing the number of pump houses required at a drilling site if the well being drilled requires a volume of pressurized drilling mud greater than what one mud pump 50 can provide.

Abstract

L'invention concerne une pompe à boue comprenant un cadre et un moteur monté sur le cadre pour faire tourner un arbre excentrique présentant des lobes excentriques sensiblement circulaires. Chaque lobe est monté de manière rotative dans une coulisse. Chaque coulisse est montée coulissante dans un cadre coulissant. Une tige de piston est couplée de manière fonctionnelle entre un ou deux côtés de chaque cadre coulissant et un module de pompe. Lorsque l'arbre excentrique tourne, chaque lobe amène la coulisse à se glisser verticalement dans le cadre coulissant, ce dernier se déplaçant horizontalement. Lorsque le cadre coulissant se déplace de manière horizontale, chaque tige de piston actionne un module de pompe. Les sorties de chaque module de pompe peuvent être couplées à un collecteur commun.
