Abstract

Hunngjengeenderoterende pumpestangskjærkoblinger (300) innbefattende et hovedsakelig sylindrisk hus (302) som har en indre overflate (306) som definerer en passasje (310) fra den øvre ende (312) til en nedre ende (314) langs en langsgående akse og en utvendig overflate (304). Skjærkoblingen (300) innbefatter også et sett av gjenger (320) rundt en indre omkrets. (322) av den øvre enden (312) for mottak av en roterende pumpestang koblet direkte inn i den øvre enden av passasjen. (310) uten et mellomliggende adapter; et sett av gjenger (320) rundt en indre omkrets (322) til den nedre enden (314) for mottak av en pumpetapp (242) koblet direkte inn i den nedre enden (314) til passasjen (310) uten et mellomliggende adapter; og en eller flere omkretsfordypninger maskinert inn i det sylindriske huset (302) mellom gjengene for å forårsake pumpestangskjærsvikt ved en forutbestemt aksiell belastning.I noen utførelsesformer er skjærkoblingene konvensjonelle hunngjengeendepumpestangskoblinger. Det er også beskrevet roterende pumpestangssammenstillinger innbefattende slike pumpestangskj ærkoblinger.Female thread end rotating pump rod shear couplings (300) including a generally cylindrical housing (302) having an inner surface (306) defining a passage (310) from the upper end (312) to a lower end (314) along a longitudinal axis and an outer surface (304). The shear coupling (300) also includes a set of threads (320) around an inner circumference. (322) of the upper end (312) for receiving a rotating pump rod connected directly into the upper end of the passage. (310) without an intermediate adapter; a set of threads (320) around an inner circumference (322) of the lower end (314) for receiving a pump pin (242) connected directly into the lower end (314) of the passage (310) without an intermediate adapter; and one or more circumferential recesses machined into the cylindrical housing (302) between the threads to cause pump rod shear failure at a predetermined axial load. In some embodiments, the shear couplings are conventional female threaded end pump rod couplings. Rotary pump rod assemblies are also described, including such pump rod shear couplings.
