Kugwiritsa Ntchito ndi Kuzindikira Zolakwa za Tricone Bits

1. Kusankha Pang'ono

Pobowola mozama mosiyanasiyana ndikukumana ndi kuphulika kosiyanasiyana, ndikofunikira kusankha kachidutswa kakang'ono koyenera kutengera cholinga chobowola (monga kuyeretsa zitsime, kubowola pulagi, kapena kubowola kolowera). M'magawo apamwamba a chitsime chosaya, sankhani akubowola kwa trione rotaryndi mkulu makina pobowola liwiro ndi ambiri spaced mano. Pazigawo zozama, momwe kubowolera kumachepa, kutentha kwa chitsime kumakwera, ndipo nthawi yosinthira pang'ono imawonjezeka, sankhani pang'ono ndi moyo wautali, kukana kutentha kwambiri, komanso kukana kuvala mwamphamvu, mongatungsten carbide tricone kubowola pang'onokapena aMtengo wapatali wa magawo TCI. Kuwonjezera mano owoneka ngati mphero kapena opindika pang'ono kumatha kupititsa patsogolo ntchito zake zachuma, makamaka pogwira ntchito ndiborewell kubowola zidutswakapena mu ntchito za migodi, kumene kulimba ndikofunikira.

2. Kugwiritsa Ntchito Bit Tricone

Ngakhale kusankha kagawo koyenera ndikofunikira, kugwiritsa ntchito moyenera ndikofunikira. Ngakhale ndi chitsanzo chabwino, kugwiritsa ntchito molakwika kungayambitse zotsatira zosasangalatsa.

(1) Kuyang'ana pang'ono ndi Kuvomereza:

Izi zikuphatikizapo kuyang'ana maonekedwe a bit, kuonetsetsa kuti ikugwirizana ndi zida zogwiritsira ntchito pang'ono, ma nozzles, ndi ma wrenches a nozzle. Musanathamangire pang'ono mu dzenje, fufuzani pamanja kuzungulira kwa tricone ndikulemba tsatanetsatane, kuphatikizapo chitsanzo chochepa, wopanga, kalasi yachitsulo, nambala ya dzenje lamadzi ndi kukula kwake, ndi mtundu wa ulusi wolumikizira, kuonetsetsa kuti ikugwirizana ndi adaputala. Ngati mukugwiritsa ntchito pobowola chitsulo chosindikizira, yang'ananinso makina osindikizira kuti mupewe kutayika kwamadzi.

(2) Kugwiritsa Ntchito Bit:

Gwiritsani ntchito chida choyenera chogwirirapo, tetezani pang'ono, ikani mafuta opangira ulusi, ndikumangitsani molingana ndi torque yomwe mwalangizidwa, kutsimikizira kuti pang'onopang'ono kumangiriridwa bwino (onetsetsani kuti chovalacho chayikidwa motsatira ndondomeko kapena malo oyenera).

(3) Kuthamanga ndi Kubwereza:

Yesetsani kutsitsa liwiro poletsa kuphulika, mitu ya casing, magawo ocheperako, magawo obowola, kapena magawo a dogleg. Tsitsani pang'ono pang'onopang'ono kuti musatseke chitoliro kapena kupanikizana pang'ono. Kwa zigawo zazitali, zungulirani pang'onopang'ono kuti musamamatire, kutayikira, kapena kutayika. Onetsetsani kuti pampu ikugwira ntchito bwino musanayikenso. Atrione rock bitnthawi zambiri imakhala yoyenera pamikhalidwe iyi chifukwa cha kuthekera kwake kuthana ndi mapangidwe osiyanasiyana.

(4) Kufufuza Pansi:

Mukayandikira pansi, yang'anani kulemera kwa bit (WOB) ndi torque. Ngati WOB ndi torque zikuwonjezeka, zimasonyeza kukhudzana ndi pansi kapena anasonkhanitsa cuttings. Pewani kutsitsa pang'ono pang'ono kapena kuyang'ana pansi, chifukwa zitha kutseka mabowo amadzi. Ngati pali zodula kapena zopinga zilizonse, kwezani chingwe chobowola, yambitsani mpope pang'onopang'ono, onetsetsani kuti pampu ikugwira ntchito moyenera, kenako yeretsani pansi polumikizira. Nthawi zonse yambani mpope molawirira ndikuyimitsa mochedwa. Ngati mukubowola m'mapangidwe ovuta,lowetsani zobowola dzinozingakhale zothandiza kwambiri.

(5) Kubowola kapena Kumanga:

Mukafika pansi, sambitsani chitsime kuti muyeretse dzenjelo musanabowole. Gwiritsani ntchito WOB yotsika, liwiro lotsika lozungulira, kuthamanga kwambiri, komanso torque yotsika kuti musunge mabowo. Pamene mukuzungulira ndi kuzungulira chingwe chobowola, kuchisuntha mmwamba ndi pansi kumathandiza kuyeretsa pang'ono. Sinthani WOB kuti musawononge pang'ono. Yang'anirani kusintha kwa pampu kuti mupewe kutsekeka kwa nozzle. Mukakumana ndi zopendekera kapena kusiyanasiyana kwa torque, sinthani liwiro, chepetsani WOB, gwiritsani ntchito liwiro lotsika, ndikukhazikitsa torque. Ngati mukugwiritsa ntchito chingwe chobowola, chepetsani kuthamanga; ngati mukugwiritsa ntchito chingwe chobowola chopanda mphamvu, onjezerani kuthamanga. Pali kusiyana pakufananiza WOB ndi liwiro. Kuthamanga kwambiri ndi kutsika kwa WOB ndikoyenera kupanga mapangidwe ofewa, pamene WOB yapamwamba ndi yotsika kwambiri ndi yabwino kwa mapangidwe olimba. Pogwira ntchito ndi mapangidwe abrasive,milled dzino trione bitsangapereke ntchito yabwinoko.

3. Tricone Bit Fault Diagnosis

(1) Kutsika pang'ono:

Pobowola m'mapangidwe okhala ndi abrasiveness kwambiri, pang'onoyo imatha kuchepa. Kagwiridwe kake kabowo ndi kudula pachitsime kumawonetsa torque yowonjezereka patebulo lozungulira kapena pagalimoto yapamwamba, kubowola kokhazikika, kuthamanga kosasunthika (kusinthasintha pakapita nthawi), komanso kusachulukira kwa torque. Kugwiritsa ntchito WOB yotsika komanso liwiro lotsika sikuchepetsa kubowola kokakamira. Ngati palibe chotchinga pambuyo pokweza pang'ono ndikuyimitsa mpope, ndipo palibe miyala ikuluikulu yomwe imadulidwa pa shaker, tinganene kuti pang'onoyo ikuchepa. Nkhaniyi ndi yofala mukamagwiritsa ntchitozidutswa zitatu za cones m'mikhalidwe yovuta.

(2) Kukomoka pang'ono:

Ngati pali kuwonjezeka kwa torque (mwachitsanzo, kuchuluka kwa katundu pa tebulo lozungulira kapena pagalimoto yapamwamba, kubowola nthawi ndi nthawi, kusintha kwakukulu kwa mphamvu zamagetsi, kapena phokoso lachilendo la injini), kuphatikizapo nthawi yogwiritsira ntchito ndi mapangidwe ake, zimasonyeza kuti pang'onopang'ono akhoza kugwidwa. Kuzungulira mwachangu ndi kubwezeretsa pang'ono kuyenera kuchitidwa. Atrione rock bitnthawi zina amatha kukumana ndi nkhaniyi, makamaka pamiyala yolimba.

(3) Kumeta mano:

Ngati pali kuwonjezeka kwa torque pa tebulo lozungulira kapena pagalimoto yapamwamba, ndipo pamene tebulo lozungulira kapena galimoto yapamwamba imayimitsidwa, pang'onopang'ono imayamba kubwerera kumbuyo, ndi kubowola kolimba, kusinthasintha kwa singano pa chizindikiro cha kulemera kwake, kuchepetsa kwambiri kapena kusakhala ndi mlingo wa kulowa, kapena kusintha kwa njira pokweza chingwe chobowola, kuwonongeka kwa dzino kungakhale kwachitika. Izi zimawonekera kwambiri m'zitsime zakuya, ndipo ziyenera kufufuzidwa ndikusinthidwa pakapita nthawi kuti zisawonongeke. Zikatero, mphero dzino pobowola migodi kapena TCI zolimba zolimba zingathandize kuchepetsa kuvala.

Zindikirani: Ngati pali vuto lililonse pobowola mwadzidzidzi, chobowocho chiyenera kuzulidwa ndikuwunikiridwa kapena kusinthidwa nthawi yomweyo. Pewani kufufuza pansi pazifukwa zotere kuti mupewe kuwonongeka kwa dzino.

M'zochita, opanga osiyanasiyana, makulidwe, ndi mitundu ya ma tricone bits, ngakhale atagwiritsidwa ntchito pansi pazigawo zovomerezeka, amakhala ndi nthawi yogwira ntchito yotetezeka. Malingana ngati palibe ntchito yolakwika yomwe ikuchitika mkati mwa nthawiyi, pang'onopang'ono imakhala yotetezeka. Apo ayi, iyenera kuchitidwa mosamala. Ndikofunika kusankha pakatilowetsani zobowola dzinokapenamilled dzino trione bitsmalingana ndi mapangidwe enieni kuti awonetsetse kuti akugwira ntchito bwino.
