Ongororo yeMibvunzo yakati wandei muCryogenic Liquid Pipeline Yekufambisa (1)

Introduction

Nekuvandudzwa kwe tekinoroji ye cryogenic, cryogenic liquid zvigadzirwa zvave kuita basa rakakosha munzvimbo dzakawanda dzakadai sehupfumi hwenyika, kudzivirira kwenyika uye tsvakiridzo yesainzi. Iko kushandiswa kweiyo cryogenic fluid kunobva pane inoshanda uye yakachengeteka kuchengetedza uye kutakura kweiyo cryogenic liquid zvigadzirwa, uye pombi yekufambiswa kweiyo cryogenic fluid inomhanya mukati memaitiro ese ekuchengetedza uye ekufambisa. Naizvozvo, zvakakosha kuve nechokwadi chekuchengetedza uye kugona kweiyo cryogenic liquid pombi kutapurirana. Nekutapurirana kweiyo cryogenic zvinwiwa, zvinodikanwa kutsiva gasi mupombi isati yatumirwa, zvikasadaro zvinogona kukonzera kutadza kushanda. Iyo precooling process ndeye isingadzivisike chinongedzo mukuita kwe cryogenic liquid chigadzirwa chekufambisa. Iyi nzira ichaunza kudzvinyirirwa kwakasimba uye zvimwe zvakashata kune pombi. Pamusoro pezvo, chiitiko chegeyser mupombi yakatwasuka uye chiitiko chisina kugadzikana chekushanda kwehurongwa, senge bofu yebazi pombi yekuzadza, kuzadza mushure mekufamba kwemvura uye kuzadza kwekamuri yemhepo mushure mekuvhurwa kwevharuvhu, zvinounza madhigirii akasiyana emhedzisiro pamidziyo uye pombi. . Nekuda kweizvi, bepa rino rinoita ongororo yakadzama pamatambudziko ari pamusoro, uye inotarisira kuwana mhinduro kuburikidza nekuongorora.

 

Kutamiswa kwegasi mumutsetse usati watakurwa

Nekuvandudzwa kwe tekinoroji ye cryogenic, cryogenic liquid zvigadzirwa zvave kuita basa rakakosha munzvimbo dzakawanda dzakadai sehupfumi hwenyika, kudzivirira kwenyika uye tsvakiridzo yesainzi. Iko kushandiswa kweiyo cryogenic fluid kunobva pane inoshanda uye yakachengeteka kuchengetedza uye kutakura kweiyo cryogenic liquid zvigadzirwa, uye pombi yekufambiswa kweiyo cryogenic fluid inomhanya mukati memaitiro ese ekuchengetedza uye ekufambisa. Naizvozvo, zvakakosha kuve nechokwadi chekuchengetedza uye kugona kweiyo cryogenic liquid pombi kutapurirana. Nekutapurirana kweiyo cryogenic zvinwiwa, zvinodikanwa kutsiva gasi mupombi isati yatumirwa, zvikasadaro zvinogona kukonzera kutadza kushanda. Iyo precooling process ndeye isingadzivisike chinongedzo mukuita kwe cryogenic liquid chigadzirwa chekufambisa. Iyi nzira ichaunza kudzvinyirirwa kwakasimba uye zvimwe zvakashata kune pombi. Pamusoro pezvo, chiitiko chegeyser mupombi yakatwasuka uye chiitiko chisina kugadzikana chekushanda kwehurongwa, senge bofu yebazi pombi yekuzadza, kuzadza mushure mekufamba kwemvura uye kuzadza kwekamuri yemhepo mushure mekuvhurwa kwevharuvhu, zvinounza madhigirii akasiyana emhedzisiro pamidziyo uye pombi. . Nekuda kweizvi, bepa rino rinoita ongororo yakadzama pamatambudziko ari pamusoro, uye inotarisira kuwana mhinduro kuburikidza nekuongorora.

 

Iyo precooling process yepombi

Mukuita kwese cryogenic liquid pombi kutapurirana, kusati kwatanga yakagadzikana yekutapurirana mamiriro, pachava nekutanga kutonhora uye inopisa pombi system uye kugamuchira michina nzira, ndiko kuti, pre-kutonhora maitiro. Mukuita uku, pombi uye yekugamuchira michina yekumira yakawandisa shrinkage kusagadzikana uye kukanganisa kumanikidza, saka inofanirwa kudzorwa.

Ngatitange nekuongorora maitiro.

Iyo yese precooling process inotanga nechisimba vaporization process, yobva yaonekwa maviri-phase kuyerera. Pakupedzisira, kuyerera kwechikamu chimwe chete kunoonekwa mushure mekunge sisitimu yanyatsotonhorera. Pakutanga kwekutonhora kwekutanga, tembiricha yemadziro inodarika tembiricha yekuzara kweiyo cryogenic fluid, uye inodarika tembiricha yepamusoro yeiyo cryogenic fluid - yekupedzisira kupisa tembiricha. Nekuda kwekutamisa kupisa, mvura iri padhuze nemadziro echubhu inodziyirwa uye inonyungudutswa pakarepo kuti iite mhute firimu, iyo inotenderedza zvachose madziro echubhu, ndiko kuti, kufashaira kwefirimu kunoitika. Mushure meizvozvo, neiyo precooling process, tembiricha yechubhu madziro zvishoma nezvishoma inodonha pazasi peyepamusoro tembiricha yekushisa, uye ipapo mamiriro akanaka ekuchinja kubikira uye bubble kufashaira anoumbwa. Kuchinja kukuru kunoitika panguva iyi. Kana iyo precooling ichiitwa kune imwe nhanho, kupisa kwepipeline uye kupisa kunopinda kwezvakatipoteredza hakuzopise iyo cryogenic fluid kune tembiricha yekuzara, uye mamiriro ekuyerera kwechikamu chimwe chete achaonekwa.

Mukuita kwehupfu hwakanyanya, kuyerera kunoshamisa uye kudzvinyirirwa kunozogadzirwa. Mukuita kwese kwekuchinja kwekumanikidza, iyo yakanyanya kudzvanywa yakaumbwa kekutanga mushure meiyo cryogenic fluid yapinda yakananga mupombi inopisa ndiyo yakanyanya amplitude mukuita kwese kwekumanikidza kushanduka, uye iyo pressure wave inogona kuonesa simba resimba rehurongwa. Naizvozvo, iyo yekutanga chete yekumanikidza wave ndiyo inowanzodzidzwa.

Mushure mekunge vharafu yavhurwa, iyo cryogenic fluid inokurumidza kupinda mupombi pasi pechiito chekumanikidza musiyano, uye iyo mhute firimu inogadzirwa ne vaporization inoparadzanisa mvura kubva pamadziro epombi, ichiita concentric axial kuyerera. Nekuti iyo yekudzivirira coefficient yemhute idiki kwazvo, saka kuyerera kweiyo cryogenic fluid yakakura kwazvo, nekufambira mberi, tembiricha yemvura nekuda kwekupisa kwemvura uye zvishoma nezvishoma kusimuka, zvichienderana nekumanikidza kwepombi kunowedzera, kuzadza kumhanya kunononoka. pasi. Kana iyo pombi yakareba zvakakwana, tembiricha yemvura inofanira kusvika pakuzara pane imwe nguva, panguva iyo mvura inomira kufambira mberi. Kupisa kubva pamadziro epombi kupinda mumvura inonzi cryogenic yose inoshandiswa pakubuda, panguva ino kukurumidza kwemvura kunowedzerwa zvikuru, kumanikidzika mupombi kunowedzerawo, kunogona kusvika 1. 5 ~ 2 nguva yekupinda mukati. Pasi pechiito chekumanikidza musiyano, chikamu chemvura chinodzoserwa kumashure kune cryogenic liquid yekuchengetedza tangi, zvichikonzera kumhanya kwekugadzirwa kwemhute kunova kudiki, uye nekuti chikamu chemhute chinogadzirwa kubva pakubuda kwepombi, kudonha kwepombi kudonha, mushure. imwe nguva, iyo pombi inogadzirisa zvakare mvura mukati mekumanikidzwa kwemamiriro ezvinhu, chiitiko chinozoonekwa zvakare, saka chinodzokororwa. Zvisinei, muchirongwa chinotevera, nokuti pane imwe dzvinyiriro uye chikamu chemvura mupombi, kuwedzera kwekumanikidzwa kunokonzerwa nemvura itsva iduku, saka kukwirira kwepamusoro kuchava kuduku kudarika peak yekutanga.

Mukuita kwese kwe precooling, iyo sisitimu haingofanire kutakura yakakura yekumanikidza wave maitiro, asi zvakare inofanirwa kutakura yakakura shrinkage kushushikana nekuda kwekutonhora. Iko kusanganiswa kwekuita kwezviviri kunogona kukonzera kukanganisa kwemaitiro kuhurongwa, saka matanho anodiwa anofanirwa kutorwa kuti aidzore.

Sezvo precooling kuyerera mwero inokanganisa zvakananga precooling maitiro uye saizi yekutonhora shrinkage kushushikana, iyo precooling process inogona kudzorwa nekudzora precooling kuyerera kuyerera. Iyo inonzwisisika yekusarudzwa musimboti we precooling kuyerera kuyerera ndeyekupfupisa precooling nguva nekushandisa yakakura precooling kuyerera padanho rekuona kuti kusimba kwekuchinja uye kutonhora shrinkage stress haipfuure iyo inobvumidzwa mhando yemidziyo nemapaipi. Kana pre-kutonhora kuyerera kuri kudiki, iyo pombi insulation kuita haina kunakira pombi, inogona kusambosvika pakutonhora.

Mukati mekugadzirisa kutonhora, nekuda kwekuitika kwezvikamu zviviri zvekuyerera, hazvibviri kuyera chiyero chechokwadi chekuyerera nekazhinji flowmeter, saka haigoni kushandiswa kutungamirira kutonga kwekutanga kwekugadzirisa kuyerera. Asi isu tinogona kutonga zvisina kunanga ukuru hwekuyerera nekutarisa kumashure kumanikidzwa kwemudziyo unogamuchira. Pasi pemamwe mamiriro ezvinhu, hukama huri pakati pekumanikidzwa kwemashure kwemudziyo unogamuchira uye kuyerera kwekutanga-kutonhora kunogona kugadziriswa nekuongorora nzira. Kana iyo precooling process inofambira mberi kune imwe-phase kuyerera mamiriro, iyo chaiyo inoyerera yakayerwa neyekuyerera inogona kushandiswa kutungamira kutonga kwe precooling kuyerera. Iyi nzira inowanzo shandiswa kudzora kuzadza kwe cryogenic liquid propellant ye rocket.

Kuchinja kwemashure ekumanikidzwa kwemudziyo wekugamuchira kunofananidzwa nekugadzirisa kwekugadzirisa sezvinotevera, iyo inogona kushandiswa kutonga zvakakodzera danho rekutanga: apo simba rekupedza kwemudziyo wekugamuchira unoramba uripo, kumanikidzwa kwemashure kuchawedzera nokukurumidza nekuda kwechisimba. vaporization yeiyo cryogenic fluid pakutanga, uye zvishoma nezvishoma inodzokera shure nekuderera kwekushisa kwemudziyo wekugamuchira uye pombi. Panguva ino, precooling simba rinowedzera.

Yakatarisa kuchinyorwa chinotevera kune mimwe mibvunzo!
