Beschreibung
Zusammenfassung:	This invention relates generally to a method and apparatus to allow high pressure pumping a fluid mixture of solid and/or abrasive particles with a liquid, and separating the fluid mixture into a solid and/or abrasive particle component and a cleaned liquid component. An embodiment includes surrounding the pump plunger/piston, and timely cycling the cleaned liquid to flush the pump check valves to displace erosive solid and/or abrasive material. Consequently, this invention allows for proper check valve sealing, extends the life of check valves, extends the life of the pump, and improves efficiency. L'invention porte de manière générale sur un procédé et sur un appareil qui permettent un pompage haute pression d'un mélange fluide de particules solides et/ou abrasives avec un liquide, et la séparation du mélange fluide en un composant de particules solides et/ou abrasives et un composant liquide nettoyé. Un mode de réalisation comprend le fait d'entourer le piston/le plongeur de la pompe et d'effectuer un cycle, de manière périodique, du liquide nettoyé pour rincer les soupapes de non-retour de la pompe afin de déplacer un matériau solide et/ou abrasif érosif. Par conséquent, l'invention permet d'étanchéifier les clapets de non-retour correctement, de prolonger la durée de vie de ceux-ci et de la pompe, et d'améliorer le rendement.
