Monga tonse tikudziwa, kusankha zigawo zofunika kwambiri za makina obowola ozungulira kumatsimikizira nthawi yomwe amagwira ntchito. Pachifukwa ichi, Sinovo, wopanga makina obowola ozungulira, adzapereka njira yosankhira mabaketi obowola.
1. Sankhani mabaketi obowolera malinga ndi momwe zinthu zilili
Ntchito yaikulu yachobowolera chozunguliraNdi kupanga dzenje pamwamba, ndipo chinthu chogwirira ntchito ndi mwala. Chifukwa cha kuya kochepa kwa dzenje lopangidwa, mwalawo wasintha kwambiri kapangidwe kake, kukula kwa tinthu tating'onoting'ono, kupendekera, kukhazikika, kuchitika ndi mphamvu yopondereza kudzera mu kayendedwe ka tectonic ndi zochita zachilengedwe zamakaniko ndi mankhwala, kotero chinthu chogwirira ntchito cha rotary drilling rig ndi chovuta kwambiri.
Mwachidule, pali magulu otsatirawa.
Malinga ndi lithology, imagawidwa m'magulu awiri: shale, sandstone, limestone, granite, ndi zina zotero.
Malinga ndi chiyambi, ikhoza kugawidwa m'miyala ya magmatic, miyala ya sedimentary ndi miyala ya metamorphic;
Malinga ndi makhalidwe a makina, imagawidwa m'magulu olimba, apulasitiki ndi omasuka. Ndiye mungasankhe bwanji kubowola bit malinga ndi momwe imakhalira? Chiyambi chotsatira ndi ichi:
(1) Dongo: chidebe chozungulira chobowolera chokhala ndi gawo limodzi pansi chimasankhidwa. Ngati kukula kwake ndi kochepa, chidebe ziwiri kapena chidebe chobowolera chokhala ndi mbale yotulutsira katundu chingagwiritsidwe ntchito.
(2) Matope, nthaka yofooka yogwirizana, dothi lamchenga ndi miyala yamtengo wapatali yokhala ndi simenti yofooka komanso tinthu tating'onoting'ono tingapangidwe ndi chidebe chobowolera pansi kawiri.
(3) Mastic yolimba: Chidebe chobowolera chozungulira chokhala ndi malo olowera dothi limodzi (pansi limodzi ndi awiri) kapena screw yowongoka yokhala ndi mano a chidebe chiyenera kusankhidwa.
(4) Chidebe chozizira kwambiri: chidebe chowongoka cha auger ndi chidebe chozungulira chobowolera zingagwiritsidwe ntchito kwa anthu omwe ali ndi ayezi wochepa, ndipo chidutswa cha auger chozungulira chingagwiritsidwe ntchito kwa anthu omwe ali ndi ayezi wochuluka. Dziwani kuti chidutswa cha auger chimagwira ntchito bwino pa dothi (kupatula matope), koma chiyenera kugwiritsidwa ntchito ngati palibe madzi apansi panthaka kuti apewe kutsekeka chifukwa cha kuyamwa.
(5) Miyala ndi miyala yolimba ndi miyala yolimba: chozungulira chozungulira ndi chidebe chozungulira cha pansi pawiri chiyenera kukhala ndi zida (doko limodzi la tinthu tating'onoting'ono tating'ono ndi cholumikizira cha tinthu tating'ono tating'ono)
(6) Mwala wozungulira: wokhala ndi pick barrel coring bit - conical spiral bit - rotary drilling bag yokhala ndi pansi pawiri, kapena pick straight spiral bit - rotary drilling bag yokhala ndi pansi pawiri.
(7) Dothi lopindika pang'ono: lokhala ndi coring bit ya mgolo wa koni - conical spiral bit - chidebe chobowola chozungulira cha pansi kawiri. Ngati kukula kwake kuli kwakukulu kwambiri, njira yobowola yoyesedwa iyenera kutsatiridwa.
