Umuyoboro wimyitozo ni igice cyumuyoboro wimyitozo, ugabanijwemo ingingo zumugabo nu ngingo zumugore, uhujwe kumpande zombi zumubiri wimyitozo. Umuhuza ahabwa umugozi wumugozi (umugozi wijimye) kugirango uhuze buri muyoboro umwe. Mubikorwa byo gucukura, ingingo ikunze gusenywa, kandi ubuso bukomatanyirijwe hamwe ningufu zitari nke zo kuruma, bityo umuyoboro wimyitozo wumuyoboro wububiko ni nini, diameter yinyuma ihuriweho nini kuruta diameter yumubiri winyuma, hamwe nicyuma kivanze hamwe nimbaraga zisumba izindi zikoreshwa. Imiyoboro yimyitozo yo murugo ikozwe muri 35CrMo ibyuma bivangwa.
Ihuza ry'umugozi wa screw rigomba kuba ryujuje ibintu bitatu, ni ukuvuga, ubunini burangana, ubwoko bwurudodo rwimigozi ni bumwe, kandi umugozi wumugabo numugore urahujwe. Ingano ihuriweho yimiyoboro itandukanye iratandukanye. Ubwoko bwurudodo rwimyanda yubunini bumwe nabwo buratandukanye. Ubwoko buhuriweho bukoreshwa na buri ruganda rukora imiyoboro nayo biragoye kuba byuzuye. Kubwibyo rero, kugirango byorohereze itandukaniro riri hagati yimiyoboro ya drill hamwe nibikorwa bya injeniyeri, API yashyizeho ingingo imwe kubwoko bwimiyoboro ihuza imiyoboro, ikora imiyoboro ya API ya drill ikoreshwa cyane mubikorwa bya peteroli.
Ibikoresho bya API birahari murwego rushaje kandi rushya. Umuyoboro wa kera wa API ya drill irasabwa gukoresha hakiri kare imiyoboro myiza ya drill, igabanijwemo ubwoko butatu: igorofa yimbere (IF), isobekeranye (FH) nibisanzwe (REG).
Ihuriro ryimbere rikoreshwa cyane cyane mubyimbye byo hanze byumuyoboro wimyitozo, urangwa na diametre yimbere yumuringoti wimyitozo hamwe na diametre yimbere yumubiri mugihe cyo kubyimba umubiri wumuyoboro, kandi irwanya amazi yo gutembera ni nto , bifasha kunoza ingufu zamazi ya bito, ariko diameter yinyuma yingingo nini kandi yoroshye kwambara.
Ihuriro risobekeranye rirakwiriye kubyimbye imbere mu miyoboro ya drill, irangwa na diamediamets ebyiri zimbere zumuyoboro wimyitozo, kandi diameter yimbere yimbere ihwanye na diameter y'imbere yo kubyimba k'umubiri, ariko bitarenze diameter y'imbere y'igice cy'umubiri. Kurwanya amazi yo gucukura atembera mu gihimba ni kinini kuruta icy'imbere imbere, ariko diameter yacyo yo hanze ni ntoya kuruta iy'imbere.
Ihuriro risanzwe rirakwiriye kubyimbye imbere yumuyoboro. Imbere ya diametre yuru rugingo ni ntoya, munsi ya diametre yimbere yimbere ya drine. Kubwibyo, hari ibice bitatu bitandukanye bya bore ya diametre yumuyoboro uhuza hamwe nibisanzwe. Amazi yo gucukura atembera muriyi ngingo hamwe nuburwanya bukomeye, ariko ifite diameter ntoya yo hanze nimbaraga nyinshi. Ihuriro risanzwe rikoreshwa muburyo buto bwa diametre ya diametre hamwe numuyoboro wa drill rever, hamwe na myitozo, ibikoresho byo kuroba, nibindi. Ubwoko butatu bwingingo zose zikoresha imigozi ya "V", ariko ubwoko bwumugozi wa screw (bugaragazwa nubugari bwa gukata hejuru), intera ya screw intera, taper nubunini biratandukanye cyane.
Kumenyekanisha hamwe
1.umwobo FH, XH, ntibisanzwe mububiko bwibikoresho, ntibisanzwe bikoreshwa.
2.koreshwa cyane NIBA nibisanzwe REG, itandukaniro niyi ikurikira:
NIBA buto 4 kuri santimetero, umugozi wa screw ugereranije ni muremure, na taper ni nto, REG 5 buto kuri santimetero, umugozi wa screw ugereranije ni muto, na taper nini. Ingano ya IF screw umugozi uri hagati ya 2-3 / 8 "kugeza 4-1 / 2", naho abarenze 4-1 / 2 "nta IF, mubisanzwe REG, aho 7-5 / 8" no hejuru bafite nta REG.
3. Uburyo rusange bwo kuvuga:
Ihagarariwe nimibare itatu, nka 310.410.411, nibindi
Umubare wambere werekana ubunini (2 ~ 7) mubisanzwe: 2-2 -, 3-3-7 / 8 ", 1/2", 4-4-1 / 2 ", 5 1/2" - 5 -, 6 -6-5 / 8 ", Nyakanga 7-5 / 8";
Umubare wa kabiri werekana ubwoko bwimigozi ya screw (hariho 1, 2, 3), 1-- NIBA; 2 --- FH; 3-- REG;
Umubare wa gatatu uhagarariye abagabo nigitsina gore (uhagarariwe na 0 na 1)
0 - Agasanduku (gore); 1 - Ipine (umugabo);
4.ubundi bwoko bwa drill pipe screw ubwoko bwurudodo ni BTC, MT, AMT, HT55 nibindi.
5.muyongeyeho, ubwoko bwimigozi isanzwe ya moteri 7-5 / 8 "REG, 6-5 / 8" REG, 4-1 / 2 "REG, nayo ifite 4-1 / 2" NIBA. Ubwoko bwa screw busanzwe bwubwoko bwa scraper na hydraulic cutter ni REG.
