Izixhumi ze-Ratchet (ze-Air Injection)

Izithako ze-ratchet zokufaka umoya zincazelo zezimoto ezikhethekile ezisiza izinhlelo zokufaka umoya emisebenzini yokuphosa, zivumela abaqhubi ukuba baphucule ukumbiwa nokufakwa kwemigodi ezindaweni ezihlukahlukene zomhlabathi. Lezi zithako zisebenzisa izakhiwo ze-ratchet ukuze ziqondise futhi zilawule ukuhamba komoya ophukile nge-drill string, kuvumela abaqhubi ukuba balawule ingcindezi nezinga lokulethwa ukuze kutholakale ukwelashwa komhlaba okuphelele nokuhlelwa komhlabathi. Ukuhlanganiswa kwezinhlelo zokulawula ezisekelwe ku-ratchet nobuchwepheshe bokufaka umoya kuhlinzeka ngendlela yokuphatha amandla ezenzakalayo phakathi kwemisebenzi yokuphosa ephelele noma engaphelele, lapho ukwabiwa komoya okulawulwayo kuthinta ngqo ukusebenza kokwandiswa komhlaba, ukuvalelwa kwezikhala, nokumelana nokungena kwepali. Ezinhlelweni zokwakha ezinzulu, izithako ze-ratchet zisebenza njengezinto ezibalulekile ngaphakathi kokuhlanganiswa kwe-drill string, zivumela abaqhubi ukuba basebenzise izindlela zokufaka umoya ukuze baphathe izimo ezinzima ezingaphansi komhlaba ezifaka phakathi ukudla kohlanga olunokhuselo, umhlaba ophephukayo, nezeluleko ezimanzi lapho ukusongela okujwayelekile kubeingicelekile. Uhlelo lwe-ratchet luvumela ukuhamba komoya okuhlosiwe futhi kuxhunywe, kusekela izindlela ezifana nokuphosa komoya, ukubiwa kwe-air-lift, nokwanda kwengcindezi yomhlabathi. Lezi zithako zibaluleke kakhulu lapho kubiwa emigudwini emixube efuna ukuphakanyiswa kwezikali ezihlukahlukene, njengoba indlela ye-ratchet yokulawula ihlinzeka ngokuqhubeka okuthembekile ezindaweni ezinengcindezi ephezulu, ezishisayo lapho izinhlelo ze-elekthronik zingase zibheke izinkinga zomjikijelo. Abakhi bezisekelo basebenzisa le teknoloji ukufinyelela ukuthuthuka okuphezulu kokunyakaza kwe-skini, ukusiza ukunciphisa ukwehla, nokwandisa amandla okuphatha okupali ngokufaka umoya okulawulwayo ngesikhathi sokufakwa. Imiphakathi yokuphosa esetshenziswa izithako ze-ratchet zokufaka umoya izuza ekulawuleni ukusebenza ngcono nokunciphisa ukusetshenziswa kwezinto uma kuqhathaniswa nezingqalasizinda ezijwayelekile. Ukuhlanganiswa kwezinto ze-ratchet nezinhlelo zokufaka umoya kuvumela ukuthuthukiswa komhlaba okungabizi ezindaweni zamadolobha lapho ukulawula ukuxhawula kubalulekile futhi imikhawulo yokukhuluma ilawulwa kakhulu. Izicelo ezijwayelekile zifaka phakathi ukwakhiwa kwelebhu ephakeme, imisebenzi yokuphakanyiswa, namaphrojekthi okuthuthukisa izisekelo lapho ukwelashwa komhlaba okunembile kuvimbela ukwehla kohlanga oluthukile. Ukucaciswa kwemishini yalezi zithako kufanele kuhlangabezane nezinga lokucindezelwa komoya ophukile ukusuka ezingeni eliphakathi kuya ezingeni eliphakeme, kanti uhla lwe-ratchet lwesithako luxhasa ukuphindaphinda ngaphandle kokukhalipha kwemishini. I-configuration ye-drill string ehlanganisa izithako ze-ratchet idinga ukuhlelwa kahle ne-hydraulic ne-pneumatic capacity yesikhwebu sokuphosa, iqinisekisa ukuhlanganiswa okuhlangene nemishini yokujikijela, imishini yokuphosa, nezinhlelo ze-casing ezisebenzelana nemigudu yokuphosa ephelele nangephezu.
