Umbhobho ogqunywe nge-vacuum(VIP) yinxalenye ebalulekileyo ekuthuthweni kwezinto ezibangela ulwelo ezibizwa ngokuba yi-cryogenic liquids, ezifana negesi yendalo enyibilikisiweyo (LNG), i-hydrogen engamanzi (LH2), kunye ne-nitrogen engamanzi (LN2). Umngeni wokugcina ezi zinto zimanzi kumaqondo obushushu aphantsi kakhulu ngaphandle kokudluliselwa kobushushu okukhulu usonjululwa kusetyenziswa iteknoloji yokukhusela i-vacuum. Le blog iza kuchaza indlela umbhobho ogqunyiweyo we-vacuumibonelela ngobushushu obuphezulu kunye nokubaluleka kwayo kumashishini axhomekeke kwiinkqubo ze-cryogenic.

Yintoni iUmbhobho ogqunywe nge-vacuum?

A umbhobho ogqunyiweyo we-vacuumineepayipi ezimbini ezixineneyo: umbhobho wangaphakathi othwala ulwelo oluyi-cryogenic kunye nombhobho wangaphandle ovala umbhobho wangaphakathi. Isithuba esiphakathi kwezi payipi zimbini siyasuswa ukuze kwenziwe i-vacuum, esebenza njengesigqubutheli sobushushu esisebenza kakuhle kakhulu. I-vacuum inciphisa ukudluliselwa kobushushu ngokuhambisa kunye nokuhambisa, okunceda ukugcina ulwelo kubushushu obuphantsi obufunekayo.

Indlela Esebenza Ngayo Ukufakwa Kwe-Vacuum

Isitshixo sokusebenza kakuhle kobushushu be-umbhobho ogqunyiweyo we-vacuum yi-vacuum layer. Ukudluliselwa kobushushu kwenzeka ngeenkqubo ezintathu eziphambili: ukuhanjiswa komoya, ukuhanjiswa komoya, kunye nemitha. I-vacuum isusa ukuhanjiswa komoya kunye nokuhanjiswa komoya kuba akukho molecule zomoya kwindawo ephakathi kwemibhobho yokudlulisa ubushushu. Ukongeza kwi-vacuum, umbhobho uhlala uquka ukhuselo olubonakalayo ngaphakathi kwendawo ye-vacuum, ukunciphisa ukudluliselwa kobushushu ngemitha.

NgobaUmbhobho ogqunywe nge-vacuum Kubalulekile kwiinkqubo zeCryogenic

Izinto ezibangela ubushushu obuphantsi zinovelwano nokuba kukunyuka okuncinci kobushushu, nto leyo enokubangela ukuba zitshiswe ngumphunga, nto leyo ekhokelela ekulahlekeni kwemveliso kunye neengozi ezinokubakho.Umbhobho ogqunywe nge-vacuumiqinisekisa ukuba ubushushu be-cryogenic fluids ezifana ne-LNG, i-LH2, okanye i-LN2 buhlala buzinzile ngexesha lokuthuthwa. Oku kunciphisa kakhulu ukwakheka kwegesi yokubilisa (i-BOG), kugcina ulwelo lukwimeko oluyifunayo ixesha elide.

Izicelo zeUmbhobho ogqunywe nge-vacuum

Umbhobho ogqunywe nge-vacuumisetyenziswa kumashishini ahlukeneyo, kuquka amandla, i-aerospace, kunye namacandelo ezonyango. Kwishishini le-LNG, ii-VIP zisetyenziselwa ukudlulisa igesi yendalo enyibilikisiweyo phakathi kweetanki zokugcina kunye nee-terminals kunye nokulahleka okuncinci kobushushu. Kwicandelo le-aerospace, ii-VIP ziqinisekisa ukudluliselwa okukhuselekileyo kwe-hydrogen engamanzi, ebalulekileyo ekuqhubeni iirokhethi. Ngokufanayo, kwinkonzo yezempilo, i-nitrogen engamanzi ithuthwa kusetyenziswa ii-VIP ukugcina izinto zebhayoloji kunye nokuxhasa ukusetyenziswa kwezonyango.

Isiphelo: Ukusebenza kakuhle kweUmbhobho ogqunywe nge-vacuum

Indima kaumbhobho ogqunyiweyo we-vacuum ekuthuthweni kolwelo olune-cryogenic akunakugqithiswa. Ngokunciphisa ukudluliselwa kobushushu ngeendlela eziphambili zokukhusela, ii-VIP ziqinisekisa ukuthuthwa okukhuselekileyo nokufanelekileyo kolwelo olune-cryogenic, nto leyo eyenza ukuba lube yimfuneko kumashishini axhomekeke kubuchwepheshe obuphantsi kobushushu. Njengoko imfuno yezicelo ze-cryogenic ikhula, ukubalulekaimibhobho egqunywe nge-vacuumiza kuqhubeka inyuka, iqinisekisa ukusebenza kakuhle kobushushu kunye nokhuseleko kwimisebenzi ebalulekileyo.
