Chiyambikusuntha

Ndi chitukuko cha ukadaulo wa cryogenic, zinthu zamadzimadzi za cryogenic zakhala zikugwira ntchito yofunika kwambiri m'magawo ambiri monga chuma cha dziko, chitetezo cha dziko ndi kafukufuku wasayansi. Kugwiritsa ntchito madzi a cryogenic kumadalira kusungidwa bwino komanso kotetezeka kwa zinthu zamadzimadzi za cryogenic, ndipo kutumiza kwa madzi a cryogenic paipi kumadutsa munjira yonse yosungira ndi mayendedwe. Chifukwa chake, ndikofunikira kwambiri kuonetsetsa kuti chitetezo ndi magwiridwe antchito a kutumiza kwa madzi a cryogenic paipi. Pa kutumiza kwa madzi a cryogenic, ndikofunikira kusintha mpweya womwe uli mupaipi musanatumize, apo ayi zingayambitse kulephera kugwira ntchito. Njira yoziziritsira isanayambike ndi mgwirizano wosapeŵeka pakuyenda kwa zinthu zamadzimadzi za cryogenic. Njirayi idzabweretsa kugwedezeka kwamphamvu kwa mphamvu ndi zotsatira zina zoyipa papaipi. Kuphatikiza apo, chochitika cha geyser mupaipi yoyima ndi zochitika zosakhazikika za magwiridwe antchito a dongosolo, monga kudzaza mapaipi osawona, kudzaza madzi pambuyo pa nthawi ndi kudzaza chipinda cha mpweya pambuyo potsegula valavu, zidzabweretsa mitundu yosiyanasiyana ya zotsatira zoyipa pazida ndi mapaipi. Poganizira izi, pepalali limapanga kusanthula kwakuya pamavuto omwe ali pamwambapa, ndipo likuyembekeza kupeza yankho kudzera mu kusanthula.

Kusamutsa mpweya pamzere musanaperekedwe

Ndi chitukuko cha ukadaulo wa cryogenic, zinthu zamadzimadzi za cryogenic zakhala zikugwira ntchito yofunika kwambiri m'magawo ambiri monga chuma cha dziko, chitetezo cha dziko ndi kafukufuku wasayansi. Kugwiritsa ntchito madzi a cryogenic kumadalira kusungidwa bwino komanso kotetezeka kwa zinthu zamadzimadzi za cryogenic, ndipo kutumiza kwa madzi a cryogenic paipi kumadutsa munjira yonse yosungira ndi mayendedwe. Chifukwa chake, ndikofunikira kwambiri kuonetsetsa kuti chitetezo ndi magwiridwe antchito a kutumiza kwa madzi a cryogenic paipi. Pa kutumiza kwa madzi a cryogenic, ndikofunikira kusintha mpweya womwe uli mupaipi musanatumize, apo ayi zingayambitse kulephera kugwira ntchito. Njira yoziziritsira isanayambike ndi mgwirizano wosapeŵeka pakuyenda kwa zinthu zamadzimadzi za cryogenic. Njirayi idzabweretsa kugwedezeka kwamphamvu kwa mphamvu ndi zotsatira zina zoyipa papaipi. Kuphatikiza apo, chochitika cha geyser mupaipi yoyima ndi zochitika zosakhazikika za magwiridwe antchito a dongosolo, monga kudzaza mapaipi osawona, kudzaza madzi pambuyo pa nthawi ndi kudzaza chipinda cha mpweya pambuyo potsegula valavu, zidzabweretsa mitundu yosiyanasiyana ya zotsatira zoyipa pazida ndi mapaipi. Poganizira izi, pepalali limapanga kusanthula kwakuya pamavuto omwe ali pamwambapa, ndipo likuyembekeza kupeza yankho kudzera mu kusanthula.

Njira yoziziritsira mapaipi isanayambe

Mu ndondomeko yonse ya cryogenic madzi payipi yotumizira, musanayambe kukhazikitsa boma lokhazikika la kutumiza, padzakhala njira yoziziritsira ndi yotenthetsera mapaipi ndi zipangizo zolandirira, ndiko kuti, njira yoziziritsira isanayambe. Mu ndondomekoyi, payipi ndi zipangizo zolandirira ziyenera kupirira kupsinjika kwakukulu ndi kuthamanga kwa mphamvu, kotero ziyenera kulamulidwa.

Tiyeni tiyambe ndi kusanthula njira yonseyi.

Njira yonse yoziziritsira imayamba ndi njira yotenthetsera mpweya mwamphamvu, kenako imawonekera kuyenda kwa magawo awiri. Pomaliza, kuyenda kwa gawo limodzi kumawonekera dongosolo litazizira kwathunthu. Poyamba njira yoziziritsira isanayambe, kutentha kwa khoma kumapitirira kutentha kwa madzi a cryogenic, komanso kumapitirira kutentha kwapamwamba kwa madzi a cryogenic - kutentha kwakukulu kotentha kwambiri. Chifukwa cha kusamutsa kutentha, madzi omwe ali pafupi ndi khoma la chubu amatenthedwa ndikutenthedwa nthawi yomweyo kuti apange filimu ya nthunzi, yomwe imazungulira khoma la chubu kwathunthu, ndiko kuti, kuwira kwa filimu kumachitika. Pambuyo pake, ndi njira yoziziritsira isanayambe, kutentha kwa khoma la chubu kumatsika pang'onopang'ono pansi pa kutentha kwa superheat kokhazikika, kenako mikhalidwe yabwino yowiritsa ndi kuwira kwa thovu kumapangidwa. Kusintha kwakukulu kwa kuthamanga kumachitika panthawiyi. Pamene kuzizira kukuchitika mpaka gawo linalake, mphamvu ya kutentha ya payipi ndi kulowa kwa kutentha kwa chilengedwe sizidzatenthetsa madzi a cryogenic kufika kutentha kwa saturation, ndipo mkhalidwe wa kuyenda kwa gawo limodzi udzawonekera.

Mu ndondomeko ya nthunzi yoopsa, kuyenda kwa madzi ndi kusinthasintha kwa mphamvu kudzapangidwa. Mu ndondomeko yonse ya kusinthasintha kwa mphamvu, kupanikizika kwakukulu komwe kumapangidwa koyamba madzi a cryogenic atalowa mwachindunji mu chitoliro chotentha ndi kuchuluka kwakukulu kwa mphamvu yonse ya kusinthasintha kwa mphamvu, ndipo mafunde a mphamvu amatha kutsimikizira mphamvu ya mphamvu ya dongosolo. Chifukwa chake, mafunde oyamba okha ndi omwe amaphunziridwa.

Pambuyo poti valavu yatsegulidwa, madzi oundana amalowa mwachangu mu payipi mothandizidwa ndi kusiyana kwa kuthamanga, ndipo filimu ya nthunzi yomwe imapangidwa ndi nthunzi imalekanitsa madziwo ndi khoma la payipi, ndikupanga kuyenda kwa axial kozungulira. Chifukwa mphamvu yotsutsa ya nthunzi ndi yaying'ono kwambiri, kotero kuchuluka kwa madzi oundana ndi kwakukulu kwambiri, ndi kupita patsogolo, kutentha kwa madziwo chifukwa cha kuyamwa kwa kutentha ndikukwera pang'onopang'ono, motero, kuthamanga kwa payipi kumawonjezeka, liwiro lodzaza limachepa. Ngati payipiyo ndi yayitali mokwanira, kutentha kwa madzi kuyenera kufika pa saturation nthawi ina, pomwe madziwo amasiya kupita patsogolo. Kutentha kuchokera pakhoma la payipi kupita ku madzi oundana kumagwiritsidwa ntchito potulutsa nthunzi, panthawiyi liwiro la nthunzi limawonjezeka kwambiri, kuthamanga kwa payipi kumawonjezekanso, kumatha kufika nthawi 1.5 ~ 2 ya kuthamanga kwa inlet. Pansi pa kusintha kwa kuthamanga kwa mpweya, gawo la madzi lidzabwezedwa ku thanki yosungira madzi ya cryogenic, zomwe zimapangitsa kuti liwiro la kupanga nthunzi likhale lochepa, ndipo chifukwa chakuti gawo la nthunzi yopangidwa kuchokera ku kutuluka kwa chitoliro, kutsika kwa kuthamanga kwa chitoliro, pakapita nthawi, payipi idzakhazikitsanso madziwo mu mikhalidwe yosiyana ya kuthamanga kwa mpweya, chochitikacho chidzawonekeranso, motero mobwerezabwereza. Komabe, mu ndondomeko yotsatirayi, chifukwa pali kupanikizika kwina ndi gawo la madzi mu chitoliro, kukwera kwa kuthamanga komwe kumachitika chifukwa cha madzi atsopano ndi kochepa, kotero nsonga ya kuthamanga kwa mpweya idzakhala yaying'ono kuposa nsonga yoyamba.

Mu ndondomeko yonse yoziziritsa isanayambike, dongosololi siliyenera kungopirira mphamvu yaikulu ya mafunde, komanso liyeneranso kupirira kupsinjika kwakukulu chifukwa cha kuzizira. Kuchitapo kanthu pamodzi kwa ziwirizi kungayambitse kuwonongeka kwa kapangidwe ka dongosolo, kotero njira zofunika ziyenera kutengedwa kuti zithetsedwe.

Popeza kuchuluka kwa madzi ozizira kumayamba kukhudza mwachindunji njira yoziziritsira komanso kukula kwa kuzizira, njira yoziziritsira ikhoza kulamulidwa poyang'anira kuchuluka kwa madzi ozizira. Mfundo yoyenera yosankha kuchuluka kwa madzi ozizira ndi kufupikitsa nthawi yoziziritsira pogwiritsa ntchito kuchuluka kwa madzi ozizira kumayamba kuzizira poganizira kuti kusinthasintha kwa kuthamanga kwa madzi ndi kuzizira sikupitirira kuchuluka kwa zida ndi mapaipi omwe amaloledwa. Ngati kuchuluka kwa madzi ozizira kusanayambe kuzizira kuli kochepa kwambiri, mphamvu yoteteza madzi paipi siili yabwino paipi, mwina singafike pamlingo wozizira.

Pa nthawi yoziziritsa madzi isanazire, chifukwa cha kuchitika kwa kayendedwe ka magawo awiri, n'zosatheka kuyeza kuchuluka kwa madzi enieni pogwiritsa ntchito choyezera madzi wamba, kotero sichingagwiritsidwe ntchito kutsogolera kuwongolera kuchuluka kwa madzi omwe asanafike kuziziritsa. Koma tikhoza kuweruza mwachindunji kukula kwa madziwo poyang'anira kuthamanga kwa madzi kumbuyo kwa choyezera madzi. Pazifukwa zina, ubale pakati pa kuthamanga kwa madzi kumbuyo kwa choyezera madzi ndi kuyenda kwa madzi asanafike kuziziritsa madzi ukhoza kudziwika pogwiritsa ntchito njira yowunikira. Pamene njira yoziziritsa madzi ikupita patsogolo kufika pamlingo wa kuyenda kwa madzi kwa gawo limodzi, kuyenda kwenikweni komwe kumayesedwa ndi choyezera madzi kungagwiritsidwe ntchito kutsogolera kuwongolera kuyenda kwa madzi asanafike kuziziritsa. Njirayi nthawi zambiri imagwiritsidwa ntchito kuwongolera kudzazidwa kwa madzi opangidwa ndi cryogenic a rocket.

Kusintha kwa mphamvu yakumbuyo ya chotengera cholandirira kumafanana ndi njira yoziziritsira motere, zomwe zingagwiritsidwe ntchito kuweruza moyenerera gawo lozizira: pamene mphamvu yotulutsa mpweya ya chotengera cholandirira imakhala yosasintha, mphamvu yakumbuyo imawonjezeka mofulumira chifukwa cha nthunzi yamphamvu ya madzi a cryogenic poyamba, kenako imabwerera pang'onopang'ono ndi kuchepa kwa kutentha kwa chotengera cholandirira ndi payipi. Panthawiyi, mphamvu yoziziritsira imawonjezeka.

Yang'anani nkhani yotsatira kuti mudziwe mafunso ena!
