Mumaindasitiri nesainzi dzinoda mari yakawanda, kuwana zvinhu kubva panzvimbo A kusvika panzvimbo B patembiricha yakakodzera kunowanzova kwakakosha. Funga nezvazvo seizvi: Fungidzira uchiedza kuendesa ice cream pazuva rinopisa—unoda chimwe chinhu kuti chigare chakaomeswa nechando! "Chimwe chinhu" ichocho kazhinji chinowanzoMapaipi Anoputira Vacuum(VIPs) nehama dzavo dzakasarudzwa,Mapaipi Akaputirwa Nevacuum(VJPs). Masisitimu aya anoshandisa nzira yekuchenjera: anogadzira vacuum yakakwana yekudzivirira kupisa, zvichiita kuti ive yakakodzera kutakura zvinhu zvinotonhora zvakanyanya kana zvinonzwa kupisa zvakachengeteka, zvinobudirira, uye zvisingadhuri. Ngationgororei kuti mapaipi aya anoita basa rakakosha sei muhupenyu hwemazuva ano.

Kushandiswa kwakajairika kweMapaipi Anoputira Vacuum? Cryogenics, hongu! Zvikuru sei,Mapaipi Akaputirwa Nevacuumndiyo nzira yakanakisisa yekufambisa gasi rechisikigo rakanyungudutswa (LNG), nitrogen yemvura (LIN), oxygen yemvura (LOX), argon yemvura (LAR), uye hydrogen yemvura (LH2). Mapaipi aya ane madziro maviri, ane vacuum yakakwira pakati pemadziro, anoderedza kupisa zvakanyanya, achideredza gasi re "boil-off" (BOG) rinobuda kana zvigadzirwa izvi zvadziya. Izvi zvakakosha kune LNG Terminals & Bunkering, Industrial Gas Production & Distribution uye Aerospace & Research.

AsiMapaipi Anoputira VacuumHazvisi zve cryogenics chete. Zvinonyanya kukosha mukugadzirwa kwemakemikari:

ü Kutakura Ethylene Inotonhora: Kuchengeta ethylene (chinhu chikuru chinovaka mupurasitiki) mvura iri pa -104°C panguva yekutakura.

Kubata neCarbon Dioxide (LCO2): Kuchengetedza tembiricha yakaderera inodiwa pakugadzirwa kweCO2 yemhando yepamusoro yechikafu uye yeindasitiri, kudzivirira kupwanyika kwemhepo uye kuunganidzwa kwesimba.

ü Kuendeswa Kwemakemikari Akakosha: Kupa nzvimbo yakagadzikana, inodzorwa nekupisa kwekutakura makemikari anonyanya kukuvadza, kudzivirira kusawirirana kusingadiwe kana kuora.

Chii chinoita kutiMapaipi Anoputira VacuumkunyanyaMapaipi Akaputirwa Nevacuum, zvakakosha kudaro mumaindasitiri aya? Heano mamwe mabhenefiti makuru:

1. Kudzivirira Kusina Kuenzana: Muchina wekupisa wakakwira (unowanzova <10^-3 mbar) unoita kuti kupisa kusafambiswe zvakanaka, zvichiita kuti ushande zvakanyanya kupfuura muchina wekupisa wekare.
2. Hapana Kunyungudika: Rusvingo rwekunze rweMapaipi Akaputirwa NevacuumInogara pedyo netembiricha yemukamuri, ichidzivirira kuumbwa kwechando nechando - izvo zvinowedzera kuchengetedzeka uye zvinoderedza ngura.
3. Kuderedza Kurasikirwa Kwechigadzirwa: Zvakakosha kuchengetedza mari ne cryogenics, kuderedza kurasikirwa kwechigadzirwa panguva yekutumira nekuchengetedza.
4. Kuchengetedzwa Kwakawedzerwa:Mapaipi Akaputirwa Nevacuumzvinopa nzira yekudzivirira zvimwe, zvichideredza njodzi yekubuda kwemvura.
5. Hupenyu Hurefu: Simbi isina ngura yakagadzirwa nemazvoMapaipi Akaputirwa Nevacuuminopa kugara kwenguva refu uye kuchengetedza kushoma.

Sezvo maindasitiri achitarisira ramangwana - nehydrogen yemvura kuti ive nesimba rakachena, zvinodiwa pakuchena kwakanyanya, uye zvinodiwa kuti pave nekushanda zvakanaka - kudiwa kwetekinoroji yepamusoro yekudzivirira vacuum insulation pipeline (uye yakasimba).Mapaipi Akaputirwa Nevacuumkunyanya) zvichawedzera chete. Kugadzira zvinhu zvitsva kwakatarisana nekuwedzera hupenyu hwe vacuum, kuvandudza multilayer insulation (MLI) mukati mepombi, uye kugadzira mitemo yakasimba ye ultra-high purity (UHP). Kubva pakushandisa simba repasi rose rekuchinja kwesimba neLNG kusvika pakugonesa kugadzirwa kwemachipisi nemazvo,Mapaipi Anoputira Vacuumuye Vacuum Jacketed Pipes mhinduro dzinokosha dzeinjiniya, dzichivimbisa kufamba zvakanaka kwemhepo mukati mekudzivirira kupisa kwakakwana. Muchidimbu, zvinoratidza simba rekudzivirira kupisa kwemhepo mukukunda matambudziko ekupisa.
