Drilling swivel: injongo, izinhlobo, izici

Ovundlile imishini ohlangothini - eyodwa yezindlela ethandwa kakhulu kwemithombo esikhiqiza, esetshenziswa ngesikhathi umsebenzi wokulungisa, ebeka yokuxhumana imigqa ngaphansi imizila yezokuthutha ekhona. Uma usebenzisa le ndlela ka imishini kwenzeka ngokubhujiswa kancane emhlabeni afanayo, okuyinto esihle kwato nomthwalo umthamo. Omunye izakhi eziyinhloko amayunithi ehilelekile ukusungulwa kokubili mpo futhi enezingqimba ohlangothini emithonjeni, imishini swivel kuyinto. Ngaphandle kwale indlela, akunakwenzeka ukuba isebenze kwi iphuzu ukuthuthukiswa inhlabathi. Ukusetshenziswa Its lesifanele ivumela ukuthola wayefisa imbobo ubukhulu abafika kwabangu-10 kwangu.

aphoyintimenti

Noma yimuphi Rig inezigaba ezintathu eziyinhloko - ngenela uhlelo, swivel kanye string sokuprakthiza. Okuhambayo uhlelo isakhiwo asekelayo engiwakhulume uma udala imithombo mpo. It ukhonza njengelungu ukuhamba imishini imishini, kudala isidingo cwilisa in imishini phansi amandla futhi unesibopho ukuzinza ohlelweni lonke. Ngezinye netjheweni uhlelo efakwe Rotor ujikelezisa ikholomu (okuthunyelwe igcwele) lignite inhlabathi ukusebenza asebenze. Drilling swivel kuyinto isixhumanisi Lesisemkhatsini phakathi kwalezi zici ezimbili. Kuyadingeka ukugcina isisindo entsanjeni sokuprakthiza, siwasebenzise uketshezi ukunikezela ukuvimbela kuhlanekezela izindophi. I ovundlile ohlangothini imishini swivel unamathele isixhumanisi ikheshi - indlela yokuxhuma kukholamu nedivaysi oluhamba sokuprakthiza ngendiza kusengaphambili. Kunezinhlobo ezintathu oyinhloko swivel - ukugeza, amandla nokusebenza. Uhlobo ngalunye has izici zayo siqu.

washover swivel

Uhlambulule imishini swivel isetshenziselwa ukusuthisa ikhambi esikhundleni yokwemba. Ikhipha kuba isilinda side eziyize okuyinto ibekwe endaweni asakazwe metal kulayini noma izindlu. Uhlaka unamathele Rotor ngu lomnyango, noma okuthiwa icici. I ukugeza umzimba has a swivel esidayisa ekhethekile okuyinto ixhunywe ipayipi lamanzi usinika ketshezi. Isixazululo lidlule ngaphansi kwengcindezi okusezingeni eliphezulu ngokusebenzisa isilinda eziyize zedivayisi echazwe iwela ikholomu rotary, bese lapho sibhekene uqobo. Inqubo lakhukhula inhlabathi. Flushing, noma bentonite, sokuprakthiza igeja libhekene amandla okudlulisela mandla ngokusebenzisa umzimba wakho. Ngesisekelo le Inkomba angawodwa lokulinganisa amathani 20, 30, 50 noma ngaphezulu.

swivel Industrial namandla

Amadivayisi amandla subtype lisetshenziswe esigabeni sokugcina inqubo imishini. onqenqemeni layo elingenhla has a drive rotary kanye nemishini. Ngosizo lwabo swivel eqala umsebenzi Rotor, ukunciphisa izindleko nekunonophisa Ngenxa yokuthi kwase kumiswe kahle. Amamodeli lokhu subtype kuhluke umthamo futhi isici umbono uxhumano. Operating lwedivayisi wenza imisebenzi emibili - ngokudala amandla ukujikeleza (ngedivaysi esishunyekiwe) kanye nokuhlinzekwa ikhambi egeza. Ungenza noma yikuphi ukusebenza downhole lapho uxhumeke string sokuprakthiza futhi swivel ethulwa. Drilling Rig, uthole inhlanganisela efanayo, ngeke bavumele ukusebenza izicelo professional.

Izimfuneko imishini swivel

Kuyinto swivel imishini akuyona ngaphandle engeyokuqala yokuxhuma, yakhelwe ukusebenza ezimweni ezinzima. Kumelwe ugcine yobunzima ngomfutho ophakeme kwenzeka ohlelweni nokusakazwa Rig imishini. Ngaphezu kwalokho, kumelwe sikhuthazele engazinzile futhi umthwalo kushintshana. Phakathi ukujikeleza string sokuprakthiza avele sindisa njengoba static nezingcindezi ashukumisayo, lapho ukufakwa kumelwe sibhekane. Ngaphezu kwalokho, imishini swivel kumele babe isivikelo ukugqwala bese enamathela ekhethekile yokusimamisa bafake ukumelana.

ukhethe Izici

Ukuze ngobuqotho nangokuzikhandla imishini kubalulekile swivel nazo zonke izimfuneko ezichazwe ngenhla. Ngaphezu kwalokho, kumelwe futhi ukuhlangabezana nezidingo lolu hlobo imishini imithetho eyisisekelo:

• Ubukhulu transverse akufanele zivimbela ukunyakaza netjheweni uhlelo ngesikhathi ezithothene lomsebenzi, kanye nomthamo string sokuprakthiza.
• Coupling nge esiphathiswa sokuprakthiza umbhoshongo iyunithi kumele kube okunokwethenjelwa futhi ezanele ukuliqaqa imishini emva kokuphothulwa umsebenzi.
• I mnandi kufanele ngokulinganayo basakaza kulo lonke isakhiwo, ukuze swivel sokuprakthiza wosayizi omncane akusho overheat.

Ukuze kwandiswe imishini, ukusebenza kunconywa ukukhetha izingxenye imishini, ingxenye okungaba ngokushesha futhi kalula indawo uma bafake ngokweqile. Kubalulekile ukukhumbula ukuthi nokwethenjelwa ukuhlala phakade swivel incike kahle nokuphila inkonzo yonke imishini Rig.

isiphetho

Ngisho noma uhlela ukuthuthukisa kahle kwisayithi, it is hhayi Kunconywa ukuqoqa swivel Rig izandla. Lokhu imishini eyinkimbinkimbi ukuthi iyahlangabezana nezidingo eliphezulu bafake ukumelana. Kusukela ukuqina yayo futhi waba nokwethenjelwa kuncike umsebenzi wonke Rig, kusukela ngenela uhlelo ziphethe Rotor, sokuprakthiza induku sokuprakthiza. amaphrojekthi Special kufanele kwenziwe ngokuvumelana imidwebo wavumelana umklami abanolwazi. Ziqukethe ulwazi mayelana tolerances futhi ukwelashwa ezonikeza eside ifindo ukusebenza, kucatshangelwa ukusebenza zonke izakhi ze-Rig imishini.
