Title
(EN) FRACTURING PUMP SYSTEMS HAVING A HYDRAULICALLY-DRIVEN ASSEMBLY APPLYING VARIABLE AMOUNTS OF PRESSURE ON PACKING
(FR) SYSTÈMES DE POMPE DE FRACTURATION AYANT UN ENSEMBLE À ENTRAÎNEMENT HYDRAULIQUE APPLIQUANT DES DEGRÉS VARIABLES DE PRESSION SUR UN EMBALLAGE
Abstract
(EN)
A fracturing pump system includes a fluid end having a cylinder and a piston movable to pressurize fluid in the cylinder. The cylinder has at least one cylinder sidewall, packing located to prevent fluid from leaking between the piston and the cylinder sidewall, and a hydraulically-driven assembly configured to apply variable amounts of pressure on the packing.
(FR)
L'invention concerne un système de pompe de fracturation comprenant une extrémité de fluide ayant un cylindre et un piston mobile pour mettre sous pression un fluide dans le cylindre. Le cylindre a au moins une paroi latérale de cylindre, un emballage situé pour empêcher un fluide de fuir entre le piston et la paroi latérale de cylindre, et un ensemble à entraînement hydraulique configuré pour appliquer des degrés variables de pression sur l'emballage.
