Cholumikizira cha chitoliro chobowolera ndi gawo la chitoliro chobowolera, chogawidwa m'magulu a amuna ndi akazi, cholumikizidwa kumapeto onse a thupi la chitoliro chobowolera. Cholumikiziracho chimaperekedwa ndi ulusi wokulungira ulusi (ulusi wokhuthala wa screw) kuti chilumikize chitoliro chilichonse chobowolera. Pobowolera, cholumikiziracho nthawi zambiri chimasweka, ndipo pamwamba pa cholumikiziracho pamakhala mphamvu yayikulu yoluma, kotero makulidwe a khoma la cholumikizira cha chitoliro chobowolera ndi akulu, m'mimba mwake wakunja wa cholumikiziracho ndi waukulu kuposa m'mimba mwake wakunja wa chitoliro, ndipo chitsulo cholungidwa chokhala ndi mphamvu zambiri chimagwiritsidwa ntchito. Cholumikizira cha chitoliro chobowolera cha m'nyumba nthawi zambiri chimapangidwa ndi chitsulo cholungidwa cha 35CrMo.
Kulumikizana kwa ulusi wa screw kuyenera kukhala ndi zinthu zitatu, zomwe zikutanthauza kuti kukula kwake ndi kofanana, mtundu wa ulusi wa screw ndi wofanana, ndipo ulusi wa screw wamwamuna ndi wamkazi ndi wofanana. Kukula kwa ma connection a payipi yobowola yosiyana ndi kosiyana. Mtundu wa ulusi wa payipi yobowola yofanana ndi wosiyana. Mtundu wa ma connection omwe amagwiritsidwa ntchito ndi wopanga ma payipi obowola aliyense ndi wovuta kukhala wogwirizana kwathunthu. Chifukwa chake, kuti athe kusiyanitsa pakati pa ma connection a payipi yobowola ndi ntchito zaukadaulo, API yapanga njira zofanana pa mtundu wa ma connection a payipi yobowola, ndikupanga ma connection a payipi yobowola ya API omwe amagwiritsidwa ntchito kwambiri mumakampani opanga mafuta.
Ma API payipi fittings alipo mu miyezo yakale ndi yatsopano. Cholumikizira chakale cha API drill pipe chimaperekedwa kuti chigwiritsidwe ntchito koyambirira kwa payipi yopyapyala, yomwe imagawidwa m'mitundu itatu: internal flat (IF), perforated (FH) ndi regular (REG).
Cholumikizira chamkati chosalala chimagwiritsidwa ntchito makamaka pakukhuthala kwakunja kwa chitoliro chobowola, chomwe chimadziwika ndi m'mimba mwake wamkati wa chitoliro chobowola ndi m'mimba mwake wamkati wa cholumikizira pakukhuthala kwa chitolirocho, ndipo kukana kwa madzi obowola ndi kochepa, zomwe zimathandiza kukonza mphamvu ya madzi ya chobowola, koma m'mimba mwake wakunja wa cholumikiziracho ndi waukulu komanso wosavuta kuvala.
Cholumikizira chobowolacho chili choyenera kukhuthala kwa mkati mwa chitoliro chobowola, chomwe chimadziwika ndi ma diamediamets awiri amkati mwa chitoliro chobowola, ndipo m'mimba mwake mwa cholumikiziracho ndi wofanana ndi m'mimba mwake wa mkati mwa chitoliro chobowola, koma chocheperako kuposa m'mimba mwake wa mkati mwa chitolirocho. Kukana kwa madzi obowola omwe akuyenda kudzera mu cholumikiziracho ndi kwakukulu kuposa kwa cholumikizira chamkati chosalala, koma m'mimba mwake wakunja ndi wocheperako kuposa wa cholumikizira chamkati chosalala.
Cholumikizira chokhazikika chimayenera kukulitsa mkati mwa chitoliro chobowola. M'mimba mwake mwa cholumikizira ichi ndi wochepa, wocheperako kuposa m'mimba mwake mkati mwa cholumikizira chobowola. Chifukwa chake, pali ma dayamita atatu osiyana a chitoliro chobowola olumikizidwa ndi zolumikizira wamba. Madzi obowola amadutsa mu cholumikizira ichi ndi kukana kwakukulu, koma ali ndi m'mimba mwake wakunja wocheperako komanso mphamvu yayikulu. Zolumikizira wamba nthawi zambiri zimagwiritsidwa ntchito pa chitoliro chobowola chaching'ono ndi chitoliro chobowola chobwerera m'mbuyo, komanso zobowola, zida zosodza, ndi zina zotero. Mitundu itatu ya zolumikizira zonse imagwiritsa ntchito ulusi wooneka ngati "V", koma mtundu wa ulusi wa screw (womwe umawonetsedwa ndi m'lifupi mwa chodulidwa chapamwamba), mtunda wa ulusi wa screw, taper ndi kukula ndizosiyana kwambiri.
Kuzindikiritsa mgwirizano
1.hole FH, XH, si yofala m'sitolo yogulitsira zida, si yogwiritsidwa ntchito kawirikawiri.
2. Kawirikawiri amagwiritsidwa ntchito ngati ndi REG wamba, kusiyana kwake kuli motere:
NGATI mabatani 4 pa inchi, ulusi wa screw ndi wokhuthala, ndipo taper ndi wocheperako, mabatani a REG 5 pa inchi, ulusi wa screw ndi wocheperako, ndipo taper ndi yayikulu. Kukula kwa ulusi wa screw wa IF kumayambira pa 2-3/8 "mpaka 4-1/2", ndipo omwe ali ndi 4-1/2 "alibe IF, nthawi zambiri REG, pomwe 7-5/8" ndi kupitirira apo alibe REG.
3. Njira yodziwika bwino yolankhulirana:
Imaimiridwa ndi manambala atatu, monga 310,410,411, ndi zina zotero.
Nambala yoyamba imasonyeza kukula (2 ~ 7) nthawi zambiri: 2-2 -, 3-3-7/8 ", 1/2 ", 4-4-1/2 ", 5 1/2 "- 5 -, 6-6-5/8", Julayi 7-5/8 ";
Nambala yachiwiri imasonyeza mtundu wa ulusi wa screw (pali 1, 2, 3), 1-- IF; 2---FH; 3-- REG;
Nambala yachitatu ikuyimira mwamuna ndi mkazi (yomwe ikuyimira 0 ndi 1)
0--Bokosi (lachikazi); 1--Pin (lachimuna);
4. Mitundu ina yodziwika bwino ya ulusi wa screw payipi yobowola ndi BTC, MT, AMT, HT55 ndi zina zotero.
5. Kuphatikiza apo, ulusi wamba wa screw wa mota 7-5/8 "REG, 6-5/8" REG, 4-1/2 "REG, ulinso ndi 4-1/2" IF. Mtundu wamba wa screw wa payipi scraper ndi hydraulic cutter ndi REG.
