Mawu Oyambakubweretsa

Ndi chitukuko chaukadaulo wa cryogenic, zinthu zamadzimadzi za cryogenic zakhala zikugwira ntchito yofunika kwambiri m'magawo ambiri monga chuma cha dziko, chitetezo cha dziko komanso kafukufuku wasayansi. Kugwiritsa ntchito kwamadzimadzi a cryogenic kumatengera kusungirako kogwira mtima komanso kotetezeka komanso kutengera zinthu zamadzimadzi za cryogenic, ndipo kufalitsa kwamadzimadzi a cryogenic kumadutsa munjira yonse yosungira ndi kuyendetsa. Chifukwa chake, ndikofunikira kuwonetsetsa chitetezo ndi mphamvu yapaipi yamadzimadzi ya cryogenic. Pakufalitsa zakumwa za cryogenic, ndikofunikira kusinthira gasi mupaipi musanayambe kufalitsa, apo ayi zitha kuyambitsa kulephera kugwira ntchito. The precooling process ndi ulalo wosalephereka pamayendedwe a cryogenic liquid product transportation. Izi zidzabweretsa kugwedezeka kwamphamvu ndi zotsatira zina zoipa paipi. Kuphatikiza apo, chodabwitsa cha geyser mupaipi yowongoka komanso kusakhazikika kwa magwiridwe antchito, monga kudzaza chitoliro chanthambi, kudzaza pambuyo pa kukhetsa kwapakati ndikudzaza chipinda cha mpweya mutatha kutsegulidwa kwa valve, kumabweretsa zovuta zosiyanasiyana pazida ndi mapaipi. . Poganizira izi, pepalali likuwunikira mozama pamavuto omwe ali pamwambawa, ndipo akuyembekeza kupeza njira yothetsera vutoli.

Kusamuka kwa gasi pamzere musanatumize

Ndi chitukuko chaukadaulo wa cryogenic, zinthu zamadzimadzi za cryogenic zakhala zikugwira ntchito yofunika kwambiri m'magawo ambiri monga chuma cha dziko, chitetezo cha dziko komanso kafukufuku wasayansi. Kugwiritsa ntchito kwamadzimadzi a cryogenic kumatengera kusungirako kogwira mtima komanso kotetezeka komanso kutengera zinthu zamadzimadzi za cryogenic, ndipo kufalitsa kwamadzimadzi a cryogenic kumadutsa munjira yonse yosungira ndi kuyendetsa. Chifukwa chake, ndikofunikira kuwonetsetsa chitetezo ndi mphamvu yapaipi yamadzimadzi ya cryogenic. Pakufalitsa zakumwa za cryogenic, ndikofunikira kusinthira gasi mupaipi musanayambe kufalitsa, apo ayi zitha kuyambitsa kulephera kugwira ntchito. The precooling process ndi ulalo wosalephereka pamayendedwe a cryogenic liquid product transportation. Izi zidzabweretsa kugwedezeka kwamphamvu ndi zotsatira zina zoipa paipi. Kuphatikiza apo, chodabwitsa cha geyser mupaipi yowongoka komanso kusakhazikika kwa magwiridwe antchito, monga kudzaza chitoliro chanthambi, kudzaza pambuyo pa kukhetsa kwapakati ndikudzaza chipinda cha mpweya mutatha kutsegulidwa kwa valve, kumabweretsa zovuta zosiyanasiyana pazida ndi mapaipi. . Poganizira izi, pepalali likuwunikira mozama pamavuto omwe ali pamwambawa, ndipo akuyembekeza kupeza njira yothetsera vutoli.

Njira yoziziritsa bwino ya payipi

Munthawi yonse ya kufalitsa kwa mapaipi amadzimadzi a cryogenic, musanakhazikitse dziko lokhazikika lopatsirana, padzakhala njira yoziziritsa komanso yotentha yapaipi ndikulandila zida, ndiko kuti, kuzizira koyambirira. Pochita izi, mapaipi ndi zida zolandirira kuti athe kupirira kupsinjika kwakukulu komanso kuthamanga kwamphamvu, chifukwa chake ziyenera kuyendetsedwa.

Tiyeni tiyambe ndi kusanthula ndondomeko.

The lonse precooling ndondomeko akuyamba ndi chiwawa vaporization ndondomeko, ndiyeno kuonekera awiri gawo otaya. Pomaliza, kutuluka kwa gawo limodzi kumawonekera pambuyo pokhazikika kwathunthu. Kumayambiriro kwa precooling ndondomeko, khoma kutentha mwachionekere kuposa machulukitsidwe kutentha kwa madzi cryogenic, ndipo ngakhale kuposa chapamwamba malire kutentha kwa cryogenic madzi - mtheradi kutenthedwa kutentha. Chifukwa cha kutentha kwa kutentha, madzi omwe ali pafupi ndi khoma la chubu amatenthedwa ndikutenthedwa nthawi yomweyo kuti apange filimu ya nthunzi, yomwe imazungulira khoma la chubu, ndiye kuti, kuwira kwa filimu kumachitika. Kenako, ndi precooling ndondomeko, kutentha kwa chubu khoma pang`onopang`ono akutsikira m`munsimu kutentha kwapamwamba kutentha, ndiyeno yabwino zinthu kusintha kuwira ndi kuwira kuwira amapangidwa. Kusinthasintha kwakukulu kwamphamvu kumachitika panthawiyi. Kuzizira koyambirira kukachitika mpaka pamlingo wina, kutentha kwa payipi ndi kutentha kwa chilengedwe sikudzatenthetsa madzi a cryogenic mpaka kutentha kwa machulukitsidwe, ndipo mawonekedwe a gawo limodzi adzawonekera.

M'kati mwa vaporization kwambiri, kutuluka kwakukulu ndi kusinthasintha kwa kuthamanga kudzapangidwa. Mu lonse ndondomeko kuthamanga kusinthasintha, pazipita kuthamanga anapanga kwa nthawi yoyamba pambuyo cryogenic madzi mwachindunji amalowa otentha chitoliro ndi matalikidwe pazipita lonse ndondomeko kuthamanga kusinthasintha, ndi kuthamanga yoweyula akhoza kutsimikizira kuthamanga mphamvu dongosolo. Chifukwa chake, mafunde oyamba amphamvu okha omwe nthawi zambiri amaphunziridwa.

Vavu ikatsegulidwa, madzi a cryogenic amalowa mwachangu mupaipi potengera kupanikizika, ndipo filimu ya nthunzi yopangidwa ndi vaporization imalekanitsa madziwo ku khoma la chitoliro, ndikupanga otaya axial concentric. Chifukwa kukana kwa nthunzi kumakhala kochepa kwambiri, motero kuthamanga kwa madzi a cryogenic ndi kwakukulu kwambiri, ndikupita patsogolo, kutentha kwamadzimadzi chifukwa cha kuyamwa kwa kutentha ndikuwuka pang'onopang'ono, motero, kuthamanga kwa mapaipi kumawonjezeka, kudzaza kumachepetsa. pansi. Ngati chitolirocho ndi chotalika mokwanira, kutentha kwamadzimadzi kuyenera kufika pamtunda, pamene madziwo amasiya kupita patsogolo. Kutentha kochokera ku khoma la chitoliro kupita kumadzi a cryogenic onse amagwiritsidwa ntchito ngati nthunzi, panthawiyi liwiro la evaporation limachulukirachulukira, kukakamiza kwa payipi kumawonjezekanso, kumatha kufika 1. 5 ~ 2 nthawi za kukakamiza kolowera. Pansi pa zochita za kuthamanga kusiyana, mbali ya madzi adzabwezeredwa kwa cryogenic madzi yosungirako thanki, chifukwa mu liwiro nthunzi m'badwo amakhala ang'onoang'ono, ndi chifukwa mbali ya nthunzi kwaiye kutulutsa chitoliro kutulutsa, chitoliro kuthamanga dontho, pambuyo Patapita nthawi, payipi adzakhala kachiwiri kukhazikitsa madzi mu mavuto kusiyana zinthu, chodabwitsa adzaoneka kachiwiri, kotero kubwereza. Komabe, muzotsatirazi, chifukwa pali kupanikizika kwina ndi gawo la madzi mu chitoliro, kuwonjezereka kwamphamvu komwe kumayambitsidwa ndi madzi atsopano kumakhala kochepa, kotero kuti kuthamanga kwapakati kudzakhala kochepa kuposa nsonga yoyamba.

Munthawi yonse yoziziritsa kuzizira, dongosololi siliyenera kungokhala ndi vuto lalikulu la mafunde, komanso liyenera kupirira kupsinjika kwakukulu chifukwa cha kuzizira. Kuphatikizika kwa ziwirizi kungayambitse kuwonongeka kwa dongosolo, choncho njira zoyenera ziyenera kuchitidwa kuti zithetsedwe.

Popeza precooling otaya mlingo mwachindunji zimakhudza ndondomeko precooling ndi kukula kwa ozizira shrinkage nkhawa, ndondomeko precooling akhoza kulamulidwa ndi kulamulira precooling otaya mlingo. Mfundo yoyenera yosankha kutentha kwa kutentha kwa precooling ndikufupikitsa nthawi yozizirira isanakwane pogwiritsa ntchito kuchuluka kwa kuzizira kokulirapo powonetsetsa kuti kusinthasintha kwamphamvu ndi kupsinjika kwa kuzizira sikudutsa zida ndi mapaipi ovomerezeka. Ngati madzi ozizirirapo asanazizire ali ochepa kwambiri, kutsekereza kwa mapaipi sikuli kwabwino papaipi, sikungafike pomwe kuzizirirako.

Mu ndondomeko precooling, chifukwa cha kuchitika kwa magawo awiri otaya, n`zosatheka kuyeza mlingo otaya kwenikweni ndi flowmeter wamba, kotero izo sizingagwiritsidwe ntchito kutsogolera kulamulira precooling otaya mlingo. Koma tikhoza kuweruza mosalunjika kukula kwa kayendetsedwe kake poyang'anira kupanikizika kumbuyo kwa chotengera cholandira. Pazifukwa zina, mgwirizano pakati pa kupsyinjika kumbuyo kwa chotengera cholandira ndi kutuluka kusanayambe kuzizira kumatha kutsimikiziridwa ndi njira yowunikira. Pamene ndondomeko ya precooling ikupita ku gawo limodzi loyenda, kuthamanga kwenikweni kumayeza ndi flowmeter kungagwiritsidwe ntchito kutsogolera kayendetsedwe ka kayendedwe ka precooling. Njirayi imagwiritsidwa ntchito nthawi zambiri kuwongolera kudzazidwa kwa cryogenic liquid propellant for rocket.

Kusintha kwa kupanikizika kwa kumbuyo kwa chotengera cholandira kumafanana ndi ndondomeko yowonongeka motere, yomwe ingagwiritsidwe ntchito kuweruza moyenera siteji ya precooling: pamene mphamvu yowonongeka ya chotengera cholandirira imakhala yosasinthasintha, kuthamanga kwa msana kumawonjezeka mofulumira chifukwa cha chiwawa. vaporization wa madzi cryogenic poyamba, ndiyeno pang'onopang'ono kugwa ndi kuchepa kwa kutentha kwa chotengera cholandira ndi payipi. Panthawi imeneyi, mphamvu ya precooling imawonjezeka.

Yang'anani ku nkhani yotsatira ya mafunso ena!
