Iyini isakhiwo kanye nesimiso sokusebenza se-sucker rod?

I-sucker rod iyingxenye ebalulekile yedivayisi yokukhiqiza uwoyela wepompo. Indima ye-sucker rod ukuxhuma ingxenye engaphezulu yeyunithi yokupompa uwoyela kanye nengxenye engezansi yepompo yokumpompa uwoyela ukuze kudluliselwe amandla, njengoba kuboniswe kuMfanekiso. Intambo ye-sucker rod yakhiwe ngama-sucker rods amaningana axhunywe ama-couplings.

I-sucker rod ngokwayo iyinduku eqinile eyenziwe ngensimbi eyindilinga, enamakhanda aqinile akhiwe emikhawulweni yomibili, enezintambo ezixhumayo kanye nesigaba esiyisikwele se-wrench. Imicu yangaphandle yama-sucker rods amabili ixhunywe ngokuhlanganisa. Ukuhlanganisa okuvamile kusetshenziselwa ukuxhuma izinduku zokuncela ezinobubanzi obulinganayo, futhi ukwehlisa ukuhlanganisa kusetshenziselwa ukuxhuma izinduku zokuncelisa ezinobubanzi obuguquguqukayo.

Njengamanje, ama-sucker rods ahlukaniswe abe izinhlobo ezimbili ezivela kubakhiqizi bezinto zokwakha, enye i-carbon steel sucker rod, kanti enye i-alloy steel sucker rod. Izinti ze-Carbon steel sucker ngokuvamile zenziwe nge-No. 40 noma 45 yekhwalithi ephezulu ye-carbon steel; i-alloy steel sucker rods zenziwe ngensimbi engu-20CrMo kanye ne-20NiMo. Ama-Sucker rods ajwayele ukuphuka eduze kwe-wellhead kanye nezintambo.

Intambo ye-sucker rod iqukethe induku epholishiwe kanye nenduku yokuncela ye-downhole. Induku yokuncela ephezulu yentambo yokuncela ibizwa ngokuthi induku epholile. Induku epholishiwe isebenzisana nebhokisi lokuvala le-wellhead ukuze kuvalwe i-wellhead.

Ama-sucker rods avamile anobuchwepheshe obulula bokukhiqiza, izindleko eziphansi, ububanzi obuncane, kanye nobubanzi bokusebenza. Izinga labo lokusebenzisa lingaphezu kuka-90% wemithombo yepompo yenduku. Ngokuvamile, izinduku zokuncela zensimbi ezivamile zihlukaniswa ngamabanga amane: Ibanga C, ibanga lika-D, ibanga lika-K kanye nebanga lika-H.

Induku yokuncela yekilasi C: isetshenziswa emithonjeni engashoni nasezimeni zomthwalo omncane.

Ama-sucker rods ekilasi D: Ama-sucker rods ensimbi asetshenziswa emithonjeni kawoyela ephakathi nendawo nesindayo.

Induku yokuncela ye-Class K: Induku yokuncela yensimbi esetshenziswa ekukhanyeni okugqwalayo kanye nemithombo kawoyela enomthwalo omaphakathi.

I-Class K kanye ne-D sucker rods: Ama-sucker rods ensimbi anokumelana nokugqwala kwe-K-class sucker rods kanye nezakhiwo zemishini ze-D-class sucker rods.

Induku yokuncela yekilasi H: Induku yokuncela yensimbi esetshenziswa emithonjeni kawoyela enomthwalo osindayo nosindayo kakhulu.

Amabanga A no-B ayipulasitiki eqiniswe ngefayibha (ipulasitiki yengilazi eqiniswe ngefayibha) ama-sucker rods: into esemqoka yomzimba we-sucker rod ipulasitiki eqinisiwe ye-fiberglass, futhi ilunga lensimbi lifakwa kuzo zombili iziphetho zomzimba we-sucker rod. Isakhiwo se-fiberglass sucker rod sakhiwe ngomzimba wenduku ye-fiberglass kanye namalunga ensimbi anemicu evamile yangaphandle ye-sucker rod kuzo zombili iziphetho. Isisindo esincane, imelana nokugqwala, ingakwazi ukuzuza ukuhamba kakhulu, futhi ingasetshenziswa kumayunithi okumpompa uwoyela anosayizi omaphakathi ukuze kuzuzwe ukumpompa okujulile.
