Kubviswa kwegasi mumutsara usati watumirwa

Nekuvandudzwa kwetekinoroji ye cryogenic, zvigadzirwa zve cryogenic liquid zvave zvichitamba basa rakakosha muminda yakawanda yakadai sehupfumi hwenyika, dziviriro yenyika uye tsvakiridzo yesainzi. Kushandiswa kwe cryogenic liquid kwakavakirwa pakuchengetedzwa uye kutakurwa kwakanaka uye kwakachengeteka kwezvigadzirwa zve cryogenic liquid, uye kutakurwa kwe cryogenic liquid paipi kunofamba nenzira yese yekuchengetedza nekufambisa. Saka, zvakakosha kwazvo kuve nechokwadi chekuchengetedzwa uye kushanda zvakanaka kwe cryogenic liquid paipi. Pakutakurwa kwe cryogenic liquids, zvakakosha kutsiva gasi riri mupaipi usati watakurwa, zvikasadaro zvinogona kukonzera kutadza kushanda. Maitiro ekutanga kutonhora isungano isingadzivisiki mukutakurwa kwe cryogenic liquid product. Maitiro aya achaunza kuvhunduka kwakasimba kwepressure uye mimwe mhedzisiro yakaipa kupaipi.

Maitiro ekugadzira pombi asati atonhora

Mukuita kwese kwe cryogenic liquid pipeline transmission, usati wagadzira mamiriro akagadzikana ekutumira, pachava ne pre-cooling uye hot piping system uye receiving tool process, kureva, pre-cooling process. Mukuita uku, pombi ne receiving tools zvichakwanisa kutsungirira shrinkage stress uye impact pressure, saka zvinofanira kudzorwa.

Ngatitangei nekuongorora maitiro acho.

Maitiro ese ekutanga kutonhora anotanga nemaitiro ekupisa zvine simba, uye zvinozobuda kuyerera kwezvikamu zviviri. Pakupedzisira, kuyerera kwechikamu chimwe chete kunoonekwa mushure mekunge sisitimu yatonhodzwa zvizere. Pakutanga kwemaitiro ekutanga kutonhora, tembiricha yemadziro zviri pachena kuti inodarika tembiricha yemvura inopenya, uye inotopfuura tembiricha yepamusoro yemvura inopenya - tembiricha yekupedzisira yekupisa. Nekuda kwekutamiswa kwekupisa, mvura iri pedyo nemadziro echubhu inopiswa uye inopiswa nekukasira kuti igadzire firimu remhepo, iro rinokomberedza madziro echubhu zvachose, kureva kuti, kufashaira kwefirimu kunoitika. Mushure meizvozvo, nemaitiro ekutanga kutonhora, tembiricha yemadziro echubhu inodzikira zvishoma nezvishoma pasi petembiricha yekupisa kwakanyanya, uye mamiriro akanaka ekuchinja kwekufashaira uye kufashaira kwebubble anoumbwa. Kuchinja kukuru kwekumanikidzwa kunoitika panguva iyi. Kana kutonhora kukaitwa kusvika padanho rakati, simba rekupisa repaipi uye kupinda kwekupisa kwezvakatipoteredza hazvizopisi mvura inopenya kusvika patembiricha yekupisa, uye mamiriro ekuyerera kwechikamu chimwe chete achaonekwa.

Mukuita kwekupwanya kwakanyanya, kuyerera kwakanyanya uye kushanduka kwesimba remhepo zvichagadzirwa. Mukuita kwese kwekushanduka kwesimba remhepo, kumanikidzwa kukuru kunoumbwa kekutanga mushure mekunge mvura yecryogenic yapinda zvakananga mupombi inopisa ndiyo amplitude yepamusoro mukuita kwese kwekushanduka kwesimba remhepo, uye mafambiro esimba remhepo anogona kuratidza kugona kwesimba remhepo. Naizvozvo, mafambiro ekutanga esimba remhepo chete ndiwo anowanzo dzidzwa.

Mushure mekunge vharuvhu yavhurwa, mvura inoyerera inopinda mupaipi nekukurumidza pasi pemusiyano wekumanikidzwa, uye firimu remhepo rinogadzirwa nekupwanya mvura rinoparadzanisa mvura kubva pamadziro epombi, zvichiita kuti kuyerera kweaxial kuenderere. Nekuti resistance coefficient yemhepo idiki kwazvo, saka mwero wekuyerera kwemvura inoyerera yakakura kwazvo, nekufambira mberi mberi, tembiricha yemvura nekuda kwekunwa kwekupisa uye kukwira zvishoma nezvishoma, zvichienderana nazvo, kumanikidzwa kwepaipi kunowedzera, kumhanya kwekuzadza kunoderera. Kana pombi yakareba zvakakwana, tembiricha yemvura inofanira kusvika pakuzara pane imwe nguva, ipapo mvura inomira kufambira mberi. Kupisa kubva pamadziro epombi kuenda kumvura inoyerera kunoshandiswa kwese kupwanya mvura, panguva ino kumhanya kwekupwanya mvura kunowedzera zvakanyanya, kumanikidzwa kuri mupombi kunowedzerawo, kunogona kusvika 1.5 ~ 2 nguva yekumanikidzwa kwekupinda. Pasi pesimba remusiyano wekumanikidzwa, chikamu chemvura chinodzoserwa kutangi rekuchengetera mvura rine cryogenic, zvichiita kuti kumhanya kwekugadzirwa kwemhepo kudiki, uye nekuti chikamu chemhepo inoburitswa kubva mukubuda kwepombi, kuderera kwekumanikidzwa kwepombi, mushure menguva yakati, pombi ichadzosa mvura mumamiriro ekusiyana kwekumanikidzwa, chiitiko ichi chichaonekwa zvakare, saka zvichadzokororwa. Zvisinei, mukuita kunotevera, nekuti pane kumanikidzwa kwakati uye chikamu chemvura mupombi, kuwedzera kwekumanikidzwa kunokonzerwa nemvura itsva kudiki, saka kukwirira kwekumanikidzwa kuchava kudiki pane kukwirira kwekutanga.

Mukati megadziriro yese yekutonhodza, sisitimu haingofanire kungova nedambudziko guru rekumanikidzwa, asiwo inofanira kutsungirira kushushikana kukuru nekuda kwechando. Kubatanidzwa kwezviviri izvi kunogona kukonzera kukuvara kwechimiro chesisitimu, saka matanho anodiwa anofanira kutorwa kuti idzore.

Sezvo mwero wekuyerera kwemvura usati watonhodza uchikanganisa zvakananga maitiro ekutonhodza kwemvura uye saizi yekudzika kwemvura inotonhora, maitiro ekutonhodza kwemvura anogona kudzorwa nekudzora mwero wekuyerera kwemvura isati yatonhodza. Nheyo yekusarudza yakakodzera yemwero wekuyerera kwemvura isati yatonhodza ndeyekupfupisa nguva yekutonhodza kwemvura nekushandisa mwero mukuru wekuyerera kwemvura isati yatonhodza nekuda kwekuona kuti kuchinja kwesimba uye kudzika kwemvura inotonhora hazvipfuure huwandu hwemidziyo nemapaipi anobvumirwa. Kana mwero wekuyerera kwemvura isati yatonhodza uri mudiki zvakanyanya, mashandiro ekudzivirira kwemvura yepombi haana kunaka kune pombi, ingasazombosvika padanho rekutonhodza.

Mukati mekutonhodza, nekuda kwekuitika kwekuyerera kwezvikamu zviviri, hazvigoneke kuyera mwero chaiwo wekuyerera ne common flowmeter, saka haigone kushandiswa kutungamira kudzora kwehuwandu hwekuyerera kwekutonhodza. Asi tinogona kutonga zvisina kunanga hukuru hwekuyerera nekutarisa kumanikidzwa kwekumashure kwemudziyo unogamuchira. Mune mamwe mamiriro ezvinhu, hukama huripo pakati pekumanikidzwa kwekumashure kwemudziyo unogamuchira nekuyerera kwekutonhodza kunogona kutsanangurwa nenzira yekuongorora. Kana maitiro ekutonhodza achienderera mberi kusvika kune imwe-phase flow state, kuyerera chaiko kwakayerwa ne flowmeter kunogona kushandiswa kutungamira kudzora kwehuwandu hwekutonhodza. Nzira iyi inowanzo shandiswa kudzora kuzadzwa kwe cryogenic liquid propellant yeroketi.

Kuchinja kwekumanikidzwa kwemusana kwemudziyo unogamuchira kunoenderana nemaitiro ekutanga kutonhora sezvinotevera, izvo zvinogona kushandiswa kutonga zvine hunhu danho rekutanga kutonhora: kana simba rekubuda kwemudziyo unogamuchira richigara riripo, kumanikidzwa kwemusana kuchawedzera nekukurumidza nekuda kwekupwanyika kwemvura ine cryogenic pakutanga, uye zvishoma nezvishoma kunodzokera shure nekuderera kwekupisa kwemudziyo unogamuchira nepaipi. Panguva ino, simba rekutanga kutonhora rinowedzera.

Ngatitarisei nyaya inotevera kuti muwane mimwe mibvunzo!
