Title (EN) ARRANGEMENT FOR CONTROLLING PRESSURE-FLUID-OPERATED DRILLING EQUIPMENT
(FR) AGENCEMENT DESTINÉ À COMMANDER UN ÉQUIPEMENT DE FORAGE ACTIONNÉ PAR LIQUIDE DE PRESSION
Abstract: front page image
(EN)An arrangement for controlling pressure-fluid-operated drilling equipment. In the arrangement, pressure of a feed channel (14a) of a feed motor (3) is controlled by a pressure limit (26), a pressure difference acting over the pressure limit (26) being proportional to a volume of flow of pressure fluid.
(FR)La présente invention concerne un agencement destiné à commander un équipement de forage actionné par liquide de pression. Dans l’agencement, la pression d’un canal d’alimentation (14a) d’un moteur d’alimentation (3) est commandée par une limite de pression (26), une différence de pression qui agit au-dessus de la limite de pression (26) étant proportionnelle à un volume d’écoulement de liquide de pression.
