Enqubweni yokumba, udaka lokumba noma amanzi emishinini yokudlulisela efana noketshezi (bheka isithombe).Iphampu ye-slurry slurry iyingxenye ebalulekile yemishini yokumba.Emjikelezweni wokumba kusetshenziswa amanzi aphakathi nendawo, amanzi aphakathi nendawo, udaka lwe-polymer noma uketshezi olungaphansi kwengcindezi, ngokusebenzisa ipayipi le-pressure, umpompi kanye nembobo yokubhoboza imbobo ephakathi nendawo ethunyelwe ngezansi, ukupholisa i-drill bit, imfucumfucu enqunyiwe isuswe futhi ithuthwe. ebusweni benhloso.Okuvamileiphampu ye-slurry slurry iwuhlobo lwe-piston noma i-plunger, eshayelwa umshini wamandla we-crankshaft rotary slurry futha, i-crankshaft bese ishayelwa nge-crosshead piston yenza ukunyakaza okuhambisanayo kusilinda sepompo elinodaka.Ku-valve yokudonsa nokukhipha okuhlukile ngaphansi kwesenzo, ukulethwa kwengcindezi nokufeza inhloso yoketshezi olujikelezayo.
Udaka endimeni yendima eyodwa nekabili yezinhlobo ezimbili, ukulingisa okukodwa kuqedele idrainamu edonsayo ihamba kuphela ngokunyakaza okuphindaphindayo kwepiston ekujikelezeni.Isenzo esiphindwe kabili esibuyisela kanye njalo isenzo sokudonsa amanzi okudonsa kabili.Uma inani lamasilinda okuhlukaniswa kwephampu ye-slurry, isilinda esisodwa, isilinda esiphindwe kabili kanye nezinhlobo ezintathu ze-cylinder 3.
Imingcele yokusebenza emibili eyinhloko yodaka yokugeleza nokucindezela.Ukukhishwa kwenani lamalitha ngomzuzu wokubala, nobubanzi kanye nezidingo zoketshezi lokumba kusuka embotsheni engemuva ekugcineni kwejubane, indawo yokuvula ibe nkulu, umthamo odingekayo ube mkhulu.Izidingo zoketshezi zibuyela ekusikeni kwe-bit rate, i-rock cuttings ephuma embotsheni impushana ebomvu ngesikhathi esifanele, futhi ilethe phezulu ngokuthembekile.I-Geological core drilling, izinga elijwayelekile lokubuya lika-0.4 kuya ku-1 amamitha ngomzuzu noma ngaphezulu.Ukucindezela kwephampu ye-slurry kuncike ekujuleni kokubhola, isiteshi samanzi lapho ukudluliswa kokumelana kanye nemvelo yoketshezi.Ukubhoboza kujule, ukumelana nepayipi kukhulu, isidingo somfutho ophakeme.Kanye nezinguquko ze-diameter yembobo, ukujula kokukhishwa kwepompo ye-slurry, isidingo singalungiswa nganoma yisiphi isikhathi.Izikhungo ezikupompo ye-slurry noma i-hydraulic motor eno-gearbox ukulungisa isivinini sayo, ukuze uguqule okukhiphayo kube.Ukuze ubambe ngokunembile ukucindezela kwepompo ye-slurry kanye noshintsho lwevolumu, imitha yokugeleza kodaka kanye negeji yokucindezela okufanele ifakwe noma nini, ukuze abasebenzi bokubhoboza baqonde ukusebenza kwamaphampu anodaka, kuyilapho ingcindezi ishintsha ngembobo inquma ukuthi isimo esijwayelekile vimbela ukwenzeka kwengozi yembobo.
