Tizilombo tomwe timabowola zolemetsa kwambiri timapangidwa ndi pini ndi zida zamabokosi ndi chubu cholemetsa chokhala ndi zopindika pakati kapena zobvala.Kukonzekera uku kumathandizira kupewa kupsinjika komwe kungachitike mwanjira ina ndikulola kubowola kolowera ndi torque yoyendetsedwa ndikuchepetsa kukakamira kosiyana.
Timaperekanso DPM-HW95 ndi DPM-HW105 yamphamvu kwambiri yowotcherera HWDP yokhala ndi 95,000 PSI ndi 105,000 PSI SMYS machubu ndi 120 KSI zolumikizira zida.
Imachepetsa mtengo wobowola (onaninso mtengo wobowola phazi lililonse) pochotsa kulephera kwa Drill Pipe m'malo osinthira.
Kuchulukitsa kwambiri magwiridwe antchito ang'onoang'ono kudzera pakuwongolera kosavuta.
Imapulumutsa ndalama zambiri pobowola molunjika posintha zingwe zambiri za Drill Collars, kuchepetsa kubowola kwa dzenje Torque ndi Koka.
Amachepetsa chizolowezi kukhala Deferentially kukakamira.Izi ndichifukwa choti ma diameter akulu ndi osavuta kumamatira kuposa ma diameter ang'onoang'ono.
Muli pamalo oyenera kudziwa malangizo ambiri oti musankhe chitoliro choyenera chobowola madzi kuti mukhale ndi nthawi yochepa komanso kuti mupulumutse ndalama pogula zabwino kwambiri komanso zokhalitsa kuchokera kuzinthu zambiri zomwe zilipo.Malangizo ochepa akuphatikizapo
1-Yang'anani zinthu zina zomwe zimapangitsa kubowola kukhala koyenera, kodalirika, komanso kolimba kuti mupange ROI yochuluka kapena kubweza ndalama.
2-Yang'anani makina awiri oyendetsa matope a injini, imodzi ya makina ozungulira kapena ma hydraulic ndi ina kuti muwongolere ndikuwonetsetsa kuti chipangizochi chikugwira ntchito mwachangu komanso moyenera.
3-Sankhani kubowola kozungulira koyenera kuti muwonjezere magwiridwe antchito komanso moyo wautali wamapaipi obowola.
