Reverse circulation drilling rigiyinsimbi yokumba eyi-rotary. Ilungele ukwakhiwa kokwakheka okuhlukahlukene okuyinkimbinkimbi njenge-quicksand, i-silt, ubumba, itshana, ungqimba lwamatshe, idwala elinesimo sezulu esishisayo, njll., futhi isetshenziswa kabanzi ekwakhiweni kwezakhiwo, amabhuloho, ukongiwa kwamanzi, imithombo, amandla, ezokuxhumana, imvula yobunjiniyela namanye amaphrojekthi.
Umgomo wokusebenza wereverse circulation drilling rig:
Lokho okubizwa ngokuthi i-reverse circulation drilling rig kusho ukuthi uma isebenza, i-rotary disc izoshayela i-drill bit ukuze isike futhi iphule idwala nenhlabathi embobeni, uketshezi olushaywayo luzogelezela ngaphansi kwembobo lusuka egebeni le-annular phakathi kwepayipi lokubhoboza. kanye nodonga lwembobo, lupholise i-drill bit, luthwale idwala kanye ne-slag lokumba umhlabathi elisikiwe, bese libuyela emhlabathini lisuka emgodini wepayipi lokubhoboza. Ngesikhathi esifanayo, uketshezi olushaywayo luzobuyela emgodini ukwenza umjikelezo. Njengoba ububanzi bomgodi ongaphakathi wepayipi lokubhoboza buncane kakhulu kunomgodi womthombo, amanzi odaka epayipini lokubhoboza akhuphuka ngokushesha kakhulu kunomjikelezo ovamile. Akuwona kuphela amanzi ahlanzekile, kodwa futhi angakwazi ukuletha i-slag yokumba phezulu kwepayipi lokubhoboza futhi ligeleze ethangini le-sedimentation yodaka, lapho udaka lungase lugaywe kabusha ngemva kokuhlanzwa.
Umgomo ukubeka ipayipi lokubhoboza emgodini ogcwele uketshezi olushaywayo, futhi ngokuzungezisa kwetafula elijikelezayo, shayela induku yokudlulisa isikwele esiqinile emoyeni kanye ne-drill bit ukuze ujikeleze futhi usike idwala nomhlabathi. Umoya ocindezelwe ufuthwa embhobhweni osekupheleni kwepayipi lokubhoboza, wenze ingxube yodaka, isihlabathi, amanzi negesi elula kunamanzi epayipi lokubhoboza inhlabathi nesihlabathi esisikwa. Ngenxa yomphumela ohlangene womehluko wengcindezi phakathi kwangaphakathi nangaphandle kwepayipi lokubhola kanye nomfutho womfutho womoya, ingxube yegesi yamanzi esihlabathi sodaka izokhuphuka kanye noketshezi olushaywayo, futhi izokhishelwa echibini lodaka lomhlabathi noma endaweni yokugcina amanzi. ithangi ngokusebenzisa hose yokucindezela. Umhlabathi, isihlabathi, amatshe kanye nemfucumfucu yamatshe kuzozinza echibini lodaka, futhi uketshezi olugelezayo luzogelezela emgodini womgodi futhi.
Izici zereverse circulation drilling rig:
1. I-reverse circulation drill ifakwe ingalo engumshini enepayipi yokubhoboza, engasetshenziswa emgodini oqondile kanye nezimo ezincane ze-vertex angle. Ngesikhathi esifanayo, i-drilling rig ifakwe ne-winch ye-hydraulic ewusizo, enciphisa kakhulu amandla okusebenza kwabasebenzi bemishini, futhi ivumela ukwakhiwa komshini okuphephile nokuphucukile.
2. I-drilling rig isebenzisa i-crawler yobunjiniyela kanye ne-hydraulic walking chassis, elula ukunyakaza futhi efaneleka kakhudlwana amathafa, amathafa, amagquma nezinye izinhlobo zomhlaba. I-chassis ifakwe ama-outriggers angu-4, ngakho-ke i-drilling rig inokudlidliza okuphansi kanye nokuzinza okuhle ngesikhathi sokwakhiwa kokumba.
3. I-reverse circulation drilling rig iqhutshwa amandla kagesi, ngomsindo ophansi nokungcola, ukusebenza kahle okuphezulu kanye ne-coefficient enkulu yokugcina amandla.
4. I-reverse circulation drilling rig inemisebenzi eminingi, futhi zonke izingxenye ezibalulekile ziyimikhiqizo eyongayo. Uhlelo lufakwe ukuvikela ukucindezela kanye namadivayisi we-alamu.
5. Izibambo nezinsimbi zawo wonke ama-actuator we-reverse circulation drilling rig zitholakala endaweni yokusebenza, elula futhi enokwethenjelwa ekusebenzeni nasekulawuleni.
6. I-reverse circulation drilling rig ithatha ifreyimu yokumba eyingqayizivele. Inqubo yokubhoboza inkulu, ukumelana ne-torsion kukhulu, isakhiwo silula, ukugcinwa kulula, ukuthutha kulula, ukusebenza kwe-orifice kulula, futhi ukumba i-engeli enkulu ye-vertex kungakhiwa.
7. I-reverse circulation drilling rig ithatha ikhanda elikhulu lamandla elinomsebenzi wokumelana nomthelela omkhulu. Ijubane lokuzungezisa lifanele izidingo zokujikeleza komoya. Amandla okuphakamisa, i-torque namanye amapharamitha angahlangabezana nezidingo ze-100M engashoni yokuzulazula kwe-air reverse circulation DTH kanye nezinye izidingo zenqubo.
