Pulagi yosungunuka ya mlatho imapangidwa ndi zinthu zatsopano, zomwe zimagwiritsidwa ntchito ngati chida chosakhalitsa chotsekera chitsime chosweka ndi kukonzanso chitsime chopingasa.
Pulagi yosungunuka ya mlatho imapangidwa makamaka ndi magawo atatu: thupi la pulagi ya mlatho, njira yomangira ndi zisindikizo. Thupi la pulagi ya mlatho limapangidwa ndi zinthu zolimba kwambiri zomwe zimatha kusungunuka, kuphatikizapo chubu chapakati, cone, mphete yoteteza ndi zolumikizira. Njira yomangira imapangidwa ndi zinthu zosungunuka ngati chonyamulira, ndipo pamwamba pake pamakhala ufa wa aloyi, tinthu ta aloyi kapena tinthu ta ceramic. Zisindikizozo ndi rabala kapena pulasitiki yosungunuka.
1. Zigawo za mapulagi osungunuka a mlatho
Mapulagi osungunuka a bridge amapangidwa makamaka ndi magnesium-aluminium alloy yamphamvu kwambiri kapena polymer material processing. Magnesium-aluminium alloy imapangidwa makamaka ndi magnesium, yokhala ndi kachulukidwe kochepa (pafupifupi 1.8 ~ 2.0g / cm³), ndipo nthawi yomweyo, ntchito yake ya mankhwala ndi yayikulu, kotero n'zosavuta kusungunuka m'malo ozizira.
Kuchuluka kwa kusungunuka kwa magnesium-aluminium alloy kumakhudzana kwambiri ndi kutentha kwa madzi ndi kuchuluka kwa Cl, kutentha kukakhala kwakukulu, kusungunuka kumathamanga; kuchuluka kwa Cl-concentration, ndi momwe filimu yodutsa pamwamba pa alloy imawonongera mwachangu, momwe madzi amayendera bwino, komanso kuchuluka kwa kusungunuka kumathamanga.
2. Njira yolumikizira pulagi yolumikizira mlatho
Matailosi olumikizira matailosi otayidwa ndi pulagi ya mlatho ndi osiyana ndi matailosi wamba achitsulo chopangidwa ndi ...
3. Mtengo Wotulutsa Chisindikizo cha Mlatho Wosungunuka wa Mlatho
Chida choyikira mipando cha Baker 20 # chidzakhala chosasunthika ngati pulagi ya mlatho ili mu casing tooling, njira yoyesera ya pulagi ya mlatho ndi chida choyikira mipando ikugwirizana bwino, pulagi ya mlatho imakhala bwino ndipo dzanja limatayika, kutayika kwa mphamvu ya dzanja ndi 12.3MPa (kutayika kofanana ndi mphamvu ya dzanja pafupifupi 155kN) monga momwe zasonyezedwera pachithunzichi.
4. Kutsekereza kwa mphamvu kwa pulagi yosungunuka ya mlatho
Pofuna kutsimikizira momwe pulagi yotulutsira mlatho imagwirira ntchito kutentha kwambiri, chogwirira ntchito cha casing chinayikidwa mu chipangizo choyesera kutentha kwambiri ndipo chinatenthedwa kufika pa 93°C. Kutentha kutakhazikika, kuthamanga kunawonjezeka pang'onopang'ono kufika pa 70 MPa. Kupanikizika kunakhazikika kwa maola 24 kenako kunasungidwa kwa mphindi 15. Pali kutsika koonekeratu kwa kuthamanga ndipo mzere woyesera kuthamanga ukuwonetsedwa pachithunzichi. Zotsatira za mayeso zikuwonetsa kuti kuthamanga kwa pulagi yotulutsira mlatho kumatha kukwaniritsa zofunikira pakupanga fracturing pamalopo.
5. Nthawi yogwira ntchito ya pulagi yosungunuka ya mlatho
Nthawi yogwirira ntchito ndi nthawi kuyambira pamene pulagi ya mlatho imayikidwa m'chitsime mpaka kusweka. Malinga ndi chitsanzo chomwe chilipo chomanga gasi wa shale, nthawi yogwirira ntchito ya pulagi ya mlatho wosweka ndi maola 24, zomwe zingakwaniritse zosowa za kumanga zitsime za gasi wa shale pamalopo, kutanthauza kuti, kuyambira nthawi yomwe pulagi ya mlatho wosweka imayikidwa m'chitsime Kuyambira ola limodzi, kumanga kwa fracturing kumatha kuchitika mkati mwa maola 24. Kuyesa kulikonse kwa magwiridwe antchito a pulagi ya mlatho wosweka kumatha kuchitika potengera nthawi yogwira ntchito ya maola 24.
