Sucker rod guider

Disclosed herein is a sucker rod guide with low friction and high wear resistance. A sucker rod guide longitudinal body, the longitudinal body being uniformly made of a copper-nickel-tin alloy and having a first end, a second end, a body outer diameter, and a smooth inner bore, the copper-nickel-tin alloy extending from the first end to the second end and adapted to engage the smooth inner bore of a sucker rod, the copper-nickel-tin alloy comprising: 5 wt% to 20 wt% nickel; from 5 wt% to 10 wt% of tin; and from 70 wt% to 90 wt% of copper. The outer surface of the guide may include a groove extending between the two ends. In a particular embodiment, the guide is made by joining together two identical guide segments. In other embodiments, the guide is a single unitary piece molded around the sucker rod. 本文公开了具有低摩擦和高耐磨性的抽油杆导向器。抽油杆导向器纵向主体，所述纵向主体均一地由铜-镍-锡合金制成，并且具有第一端、第二端、主体外径，以及光滑内孔，所述从所述第一端延伸到所述第二端，并且适于接合抽油杆的光滑内孔，所述铜-镍-锡合金包含：5wt％至20wt％的镍；5wt％至10wt％的锡；以及70wt％至90wt％的铜。导向器的外表面可包括在两端之间延伸的凹槽。在特定实施方案中，通过将两个相同的导向器节段连结在一
