Mpweya wamadzimadzi, nayitrogeni wamadzimadzi, argon vacuum cryogenic liquid tank tank

Mafotokozedwe Akatundu:

Ma tanki osungira madzi a cryogenic amagawidwa kukhala mtundu wa vacuum powder insulation ndi mtundu wa kutchinjiriza wa mumlengalenga.Kutchinjiriza ufa kumagwiritsa ntchito ufa wocheperako, fiber kapena thovu kuti muchepetse kutentha.Pali mitundu iwiri: imodzi ndikugwiritsa ntchito kutchinjiriza wamba (kutchinjiriza kokhazikika) pansi pa kupanikizika kwa mlengalenga, wosanjikiza wotsekera ndi wokulirapo, ndipo umadzazidwa ndi nayitrogeni wowuma kuti ukhalebe wolimbana bwino kuti chinyontho zisalowe ndikulowa, komanso oyenera nayitrogeni wamadzimadzi pamwamba pa kutentha;Mtundu wina wa kutchinjiriza ufa wa vacuum ndikuchotsa malo odzaza ndi ufa kuti muchepetse kutentha kwa gasi.Nthawi yomweyo, tinthu tating'onoting'ono tating'onoting'ono timafooketsanso kutengerapo kwa kutentha kwa radiation, ndikupangitsa kuti kutentha kukhale bwino.

Ubwino wazinthu:

1. Ambiri mwa tanki yosungiramo kutentha kwapansi yosungiramo zitsulo zosapanga dzimbiri zopangidwa ndi TISCO, Baosteel kapena opanga khalidwe lomwelo, silinda yamkati ndi mapaipi onse amapangidwa ndi chitsulo chosapanga dzimbiri cha austenitic, ndipo chipolopolo chakunja chimapangidwa ndi Q245R kapena Q345R kapena zofunikira zapamwamba. , zonse zogulidwa ku Anyang Iron ndi Steel, Handan Iron ndi Steel Ndi magulu ena akuluakulu opanga zitsulo zapakhomo.Zambiri mwa mbalezo zimakhazikika ndikumangirizidwa kuchokera ku zitsulo zachitsulo kuti zichepetse kugwirizana kwapakati, ndipo khalidwe la mankhwala likhoza kutsimikiziridwa.Chifukwa kuchuluka kwa zogula ndi zazikulu, mtengo wathu uyenera kutsika moyenerera.

2. Zidazo zimayesedwanso motsatira GB150-2011 "Ziwiya Zopanikizika", makulidwe, mawonekedwe ndi maonekedwe, ndi zina zotero, ndi zitsulo zopangidwa ndi zipangizo monga zida zoyesera zowonongeka zimagwiritsidwa ntchito pofufuza ndi kuyesa.Zogulitsa zina zimapangidwa ngati mapanelo oyesa zinthu ndipo kuyesa kwamakina kumachitidwa..

3. Njira yatsopano yowotcherera, zida zowotcherera zozama zolowera, kuwotcherera mbali imodzi komanso kupanga mbali ziwiri zathandiza kuti ntchitoyo ikhale yabwino, mawonekedwe ake ndi okongola kwambiri, kuchuluka kwa ziyeneretso ndikwambiri, ndipo chiwopsezo chozindikira cholakwika ndichofunikira.Onse kuwotcherera seams circumferential utenga kuwotcherera basi kapena kuwotcherera kwambiri malowedwe, ndi kuwotcherera seams a chotengera otsika kutentha ndi radiographically anayendera malinga ndi muyezo.

4. Kupindika kwa chitoliro kumachitika pamakina opindika a CNC, omwe amatsimikizira mosamalitsa kukula kwa chitoliro cha chitoliro.Palibe cholumikizira cha chigongono chomwe chimagwiritsidwa ntchito, chomwe chimachepetsa kwambiri kukana kwa mapaipi ndikuwongolera kukongola kwa mapaipi akunja.

5. Musananyamule mchenga, chinyezi ndi zonyansa zomwe zili m'malo otsekemera zimasinthidwa ndi nayitrogeni yotentha yowuma kuti pakhale malo owuma komanso kuchepetsa gwero la kutulutsa mpweya.

6. Tumizani mchenga watsopano wa ngale yotentha kuchokera kwa wopanga kupita ku fakitale kuti mudzaze, kuonetsetsa kuuma kwa mchenga wa pearlescent ndikuwongolera magwiridwe antchito a vacuuming.Kudzazidwa kwa mchenga wa ngale kumatenga ukadaulo wowonjezera wothamanga kwambiri, kuchuluka kwa mchenga wa ngale kumafika nthawi 1.5, mchenga wa ngale ndi wofanana komanso wodzaza, komanso kuteteza kutentha ndikwabwino.

7. Tanki yosungiramo imatenga njira yotenthetsera kuti iwonetsetse kuti kutentha kwa silinda yamkati kumakhala pamwamba pa madigiri 100.Ndi kutentha mkati, mpweya amamasulidwa pasadakhale, kotero kuti ayezi anapanga mu zingalowe boma sublimated pasadakhale ndi zingalowe moyo wautali.

8. Paint spray anticorrosion, gwiritsani ntchito epoxy zinc-rich primer, sprayer kawiri, makulidwe amafika ma microns 80, ndiyeno utoto wapakati, timagwiritsa ntchito utoto wachitsulo wamtambo wapakati, komanso titapopera ma microns 80 kawiri, kenako timapopera acrylic polyurethane kawiri Pamwamba. chovala chimakwirira pamwamba;makulidwe onse a zigawo zitatu za utoto ndi pafupifupi 240 microns;ndizokwera kwambiri kuposa kupopera utoto kwa opanga ambiri.

9. Malo amkati ndi akunja a thanki yamkati yachitsulo chosapanga dzimbiri ndi degreasing ndi pickling passivation.The carbon zitsulo akunja chipolopolo amathandizidwa ndi mfuti kuwombera makina zitsulo grit kuchotsa dzimbiri.Zimbiri zonse pamwamba pa thanki yosungirako zimatayidwa, ndipo dzimbiri zambiri zimaponyedwa pamwamba pa mbale yachitsulo.Maenje ang'onoang'ono amakhala ndi zomatira zolimba pambuyo popopera utoto wotsutsa dzimbiri pansi, zomwe zimapangitsa kuti utoto ukhale wabwino kwambiri wotsutsa dzimbiri.Sizimangotsimikizira maonekedwe a thanki yosungiramo, kumawonjezera moyo wa utoto, komanso kumatsimikizira moyo wa vacuum.

10. Ma valve, ma level gauges ndi vacuum vacuum amapangidwa m'nyumba, ndipo Rosemount, Wika, Helos, Best, etc. akhoza kusankhidwa.

11. Tanki yosungiramo imagwiritsa ntchito mapangidwe a valve otetezera kawiri, imodzi yosunga zobwezeretsera ndi imodzi yogwiritsidwa ntchito;pali ma valve otetezera pakati pa ma valve awiri mu payipi kuti atsimikizire chitetezo cha mankhwala.

12. Mafuta akulu a cryogenic amadzimadzi okosijeni, argon amadzimadzi, akasinja osungira a nayitrogeni amadzimadzi, akasinja osungira a LNG, ndi akasinja osungira kaboni dayokisaidi pamsika ali ndi zinthu zina zomalizidwa ndi theka-zomaliza zomwe zilipo, zomwe zimatsimikizira zomwe wogwiritsa ntchito amafunikira pakumanga. nthawi kwambiri.
