Ibhit Yezinsimbi Ezishintshwayo RC

Ibitshu equkethe i-RC ezifanele ukufaka esikhathini ezibalulekile emithini yokubola ezisebenzisa izinhlelo zokusebenza ze-reverse circulation drilling ezisetshenziselwa ukusebenza okuphezulu kokwakha izisekelo ezinzulu nezokuhlola kwezomhlaba. Lezi zinsiza zokubola ezikhethekile zihlelwe ukuze zisebenze ngaphakathi kwamadivaysi amakhanda ahlanganisiwe asebenzisa umoya ophakamisiwe, imithombo yokushaya phansi kweholo. Ukusebenza kwamafutha okuhamba okukhululiwe kwalezi zinsiza kuzenza zibe nezidingo ezibalulekile zokusebenza kokubola okuhloswe kahle, njengoba zingashintshwa ngokushesha uma sezifile noma zonakele ngaphandle kokudingeka ukususa yonke imishini yokushaya. Emisebenzini yokubola ye-reverse circulation, umoya ophakathi uphonsa ngokuhlanganyela umshini oshayayo ngenkathi ujikeleza imithi yokubola phezulu phakathi komugqa wokubola nomzila wombhobho, kuqinisekisa ukutholwa kwezigqoko ezinhle nokuvumela ukuhlolwa kwejoloji ngesikhathi sokusebenza kokubola. Ibitshu ze-RC ezivuselekile zakhiwe ukuze zingeniswe ezinhlobonhlobo zomhlabathi nezindunduma ezivame ukubonakala emaphakathini wezinhlelo zokwakha izisekelo, kuhlanganise negravel eqinile, idwala elithambile, idwala elikahle, nezinhla ezixubile zomhlabathi - amathrekhi ezindunduma. Ukukhethwa kokuma kwe-bit okufanele, ukuhlela kwe-tungsten carbide, kanye nokwakhiwa komzimba wenhlangano ye-alloy steel kuncike ezimweni zomhlaba ezithile, isivinini sokubola esifunwa, kanye nezinhloso zokukhiqiza. Izinhlelo zama-cluster hammer ezisebenzisa lezi zinsiza ezivuselekayo zisebenza kahle ikakhulukazi ezindaweni ezintsha lapho izindlela zokubola ezijwayelekile zikhombisa ukuntula ukusebenza, njengemhlabathi edumile kakhulu, amafomu e-laterite, kanye nezendlalelo zedwala ezithambile. Ikhono lokushintsha ama-bit ngokushesha nangokwezimali kuvumela abadlali ukuphatha umkhiqizo wokubola kwezinye izindawo zomhlaba nokunciphisa izindleko zomsebenzi jikelele uma kuqhathaniswa nezindlela ezidinga ukuhamba kaningi ukuze kugcinwe noma kushintshwe imishini. Imisebenzi yokwakha izisekelo ezinzulu efaka ukufakwa kwepuli ye-bore, ukwakhiwa kodonga lwe-diaphragm, nezinhlelo zokuhlola zomhlaba kuncike kakhulu ezinhlelweni zokubola ze-RC cluster hammer ezinezimiso ezithembekile eziqediwe. Lezi zinsiza zokubola zisekela izimbobo ezinkulu ezidingekayo zokwakha izisekelo ezinkulu ngenkathi kugcinwa amandla wokufaka impendulo awusizo ekwakhiweni kwezomhlaba. Ezindaweni zezulu ezishisayo nezizungezile lapho idwala elibhamukayo kanye nezendlalelo zomhlabathi eziyinkimbinkimbi zivame khona, ama-bit ze-RC athuthukisa izinga lokungena nezinga lokubola. Ikhono lokushintsha ama-bit ngokushesha kuqinisekisa isikhathi sokusebenza esincane ezindaweni zokubola ezisebenzayo, kuhlanganisa impempe kumalungelo wokwakha nezindleko zomsebenzi. Abasebenzi bokuqhuba imishini bathola umthwalo onembile wokuhamba kwama-bit avuselekayo endaweni, uma kuqhathaniswa nezinselelo ezinzima zokuphuka kwemishini. Kwababonakalisayo bokubola nabachwepheshe bezomhlaba abasebenzela emaphakathini wezokwakha oxhamazela ulwazi olucacile lokwakha izisekelo, ama-bit ze-RC avuselekayo ngaphakathi kwamadivaysi amahhashi anokuqonda okuhle kokuqina kokubola, ukuqina kwezindleko, kanye nokuguquguquka kokusebenza okudingeka emsebenzini wokwakha izisekelo ezinzulu zanamuhla.
