A method of fabricating a rod guide. The first step involves providing a sucker rod having an exterior surface with a raised profile. The second step involves providing a split sleeve having at least one segment. The split sleeve has an interior surface with a recessed profile that mates with the raised profile of the sucker rod thereby securing the sleeve against axial movement relative to the sucker rod. The third step involves providing an overlying sleeve that overlies the split sleeve to maintain the split sleeve in mating engagement with the sucker rod.
Méthode de fabrication d'un guide de tige. La première étape est de fournir une tige de pompage ayant une surface extérieure à profil surélevé. La deuxième étape consiste à fournir un manchon fendu ayant au moins un segment. Ce manchon comprend une surface intérieure munie d'un profil à rainures qui épouse le profil à saillies de la tige de pompage, évitant ainsi un déplacement axial du manchon par rapport à la tige de pompage. La troisième étape est de fournir un manchon sus-jacent qui recouvre le manchon fendu de façon à maintenir ce dernier engagé avec la tige de pompage.
