Kufanele Kugcinwe Kanjani Ukulungiswa Kwansuku Zonke Kwe-Down-the-Hole Drilling Rig?

1. Hlola njalo uwoyela we-hydraulic.

I-rig yokubhoboza i-DTH enomgodi ovulekile iyimoto engama-hydraulic, okungukuthi, ngaphandle komoya ocindezelwe, eminye imisebenzi yenziwa ngohlelo lwe-hydraulic, futhi ikhwalithi kawoyela we-hydraulic ibalulekile ekusebenzeni okuvamile kohlelo lwe-hydraulic.

① Vula ithangi likawoyela we-hydraulic bese ubheka ukuthi umbala kawoyela we-hydraulic ucacile futhi ucacile yini. Uma usuxubile noma ubolile, kumele ushintshwe ngokushesha. Uma imvamisa yokubhoboza iphezulu, uwoyela we-hydraulic ngokuvamile ushintshwa njalo ezinyangeni eziyisithupha. Ungaxubi uketshezi olubili lwe-hydraulic!

② Uwoyela we-hydraulic ofakwe umshini wokubhoboza uwoyela we-hydraulic ongagugi, oqukethe ama-antioxidants, ama-anti-grest, ama-anti-foaming agents, njll., angavimbela ngempumelelo ukugugika kwasekuqaleni kwezingxenye ze-hydraulic ezifana namaphampu kawoyela nama-hydraulic motors. Uwoyela we-hydraulic ongagugi osetshenziswa kakhulu yilawa: YB-N32.YB-N46.YB-N68, njll. Uma inombolo yokugcina inkulu, kulapho i-kinematic viscosity yamafutha we-hydraulic iphakama khona. Ngokusho kwamazinga okushisa ahlukene, uwoyela we-hydraulic we-YB-N46 noma we-YB-N68 one-viscosity ephezulu uvame ukusetshenziswa ehlobo, kanti uwoyela we-hydraulic we-YB-N32.YB-N46 one-viscosity ephansi usetshenziswa ebusika. Ngenxa yokuthi kusenezinye izinhlobo ezindala zamafutha we-hydraulic angagugi, njenge-YB-N68, YB-N46, YB-N32 njalo njalo.

2. Hlanza njalo ithangi likawoyela kanye nesihlungi sikawoyela.

Ukungcola ku-oyela we-hydraulic ngeke kubangele kuphela ukwehluleka kwama-valve e-hydraulic, kodwa futhi kuzokhulisa ukuguguleka kwezingxenye ze-hydraulic ezifana namaphampu kawoyela kanye nama-motor e-hydraulic. Ngakho-ke, simise isihlungi sokufutha uwoyela kanye nesihlungi sokubuyisela uwoyela esakhiweni ukuqinisekisa ukuhlanzeka kwamafutha ajikelezayo ohlelweni. Kodwa-ke, ngenxa yokuguguleka kwezingxenye ze-hydraulic ngesikhathi somsebenzi, ukwengeza uwoyela we-hydraulic kuzongena ngokungaqondile ekungcoleni, ngakho-ke ukuhlanza njalo ithangi likawoyela kanye nesihlungi sawoyela kuyisihluthulelo sokuqinisekisa ukuhlanzwa kwawoyela. Vimbela ukwehluleka kohlelo lwe-hydraulic futhi wandise impilo yenkonzo yezingxenye ze-hydraulic.

① Isihlungi sokumunca uwoyela esithuthukisiwe sifakwe ngaphansi kwethangi likawoyela futhi sixhunywe nembobo yokumunca uwoyela yephampu kawoyela. Ngenxa yomsebenzi waso wokuzikhiya, okungukuthi, ngemva kokususwa kwento yesihlungi, isihlungi sikawoyela singasivala ngokuzenzakalelayo imbobo kawoyela ngaphandle kokuvuza. Uma uhlanza, vele ukhulule into yesihlungi bese uyihlanza ngowoyela wedizili ohlanzekile. Isihlungi sokumunca uwoyela kufanele sihlanzwe kanye ngenyanga. Uma into yesihlungi itholakala yonakele, kufanele ishintshwe ngokushesha!

② Isihlungi sokubuyisa uwoyela sifakwe ngaphezu kwethangi likawoyela futhi sixhunywe nepayipi lokubuyisa uwoyela. Uma uhlanza, vele ukhulule isici sesihlungi bese usihlanza ngedizili ehlanzekile. Isihlungi sokubuyisa uwoyela kufanele sihlanzwe kanye ngenyanga. Uma isici sesihlungi sonakele, kufanele sishintshwe ngokushesha!

③ Ithangi likawoyela liyindawo lapho ukumuncwa kukawoyela nokubuyiselwa kukawoyela, futhi liyindawo lapho ukungcola kungenzeka khona ukuthi kuhlale futhi kugxile khona, ngakho-ke kufanele kuhlanzwe njalo. Vula ipulaki likawoyela njalo ngenyanga, khipha ingxenye kawoyela ekungcoleni okuphansi, uyihlanze kahle njalo ezinyangeni eziyisithupha, ukhulule wonke uwoyela (kunconywa ukuthi ungayisebenzisi noma ungayihlungi izikhathi eziningi), bese ufaka uwoyela omusha we-hydraulic ngemva kokuhlanza ithangi likawoyela.

3. Hlanza i-lubricator ngesikhathi bese ufaka uwoyela wokugcoba.

I-rig yokubhoboza engaphansi kwembobo ikwazi ukubhoboza idwala elishaywayo nge-impactor. Ukugcotshwa okuhle kuyisimo esidingekayo ukuqinisekisa ukusebenza okuvamile kwe-impactor. Ngenxa yokuthi kuvame ukuba namanzi emoyeni ocindezelwe futhi ipayipi alihlanzekile, ngemva kwesikhathi sokusetshenziswa, inani elithile lamanzi kanye nokungcola kuvame ukuhlala phansi kwe-lubricator, okuzothinta ukugcotshwa kanye nokuphila kwenkonzo ye-impactor. Ngakho-ke, uma kutholakala ukuthi akukho mafutha ku-lubricator noma kukhona umswakama kanye nokungcola ku-lubricator, kufanele isuswe ngesikhathi. Uma ufaka uwoyela wokugcoba, i-valve eyinhloko yokungenisa kumele ivalwe kuqala, bese i-valve yokushaqeka kufanele ivulwe ukuze kususwe umoya osele epayipini ukuze kugwenywe umonakalo. Ukusebenza ngaphandle kowoyela wokugcoba akuvunyelwe ngokuphelele!

4. Yenza umsebenzi omuhle ekusetshenzisweni kwenjini kadizili kanye nokushintsha uwoyela.

Injini kadizili ingumthombo wamandla ohlelo lonke lwe-hydraulic, oluthinta ngqo ikhono lokukhuphuka kwe-rig yokubhoboza. Amandla okuqhubekisa (okuthuthukisa), i-torque ejikelezayo, ukusebenza kahle kokubhoboza amatshe, kanye nokugcinwa ngesikhathi esifanele yizinto ezidingekayo ukuze i-rig yokubhoboza isebenze kahle.

① Izinjini zikadizili ezintsha noma ezilungisiwe kumele zisetshenziswe ngaphambi kokusetshenziswa ukuze kuthuthukiswe ukuthembeka kanye nokuphila kahle kwenjini kadizili. Zisebenze amahora angama-50 ngaphansi kwama-70% wejubane elilinganisiwe kanye nama-50% womthwalo olinganisiwe.

② Ngemva kokusebenzisa, khipha uwoyela epanini likawoyela ngesikhathi kushisa, hlanza ipani likawoyela nesihlungi sikawoyela ngodizili, bese ubuyisela uwoyela nesihlungi.

③ Ngemva kokuphela kwesikhathi sokuphumula, shintsha uwoyela bese uwuhlunga njalo emahoreni angu-250.

④ Funda ngokucophelela incwadi yemiyalelo yenjini kadizili bese wenza eminye imisebenzi yokulungisa kahle.
