Isimbuku:Iiyunithi ezili-120
Ukusetyenziswa:Ulawulo lokukhupha nokugcina imveliso ye-nitrogen engamanzi (-196°C) kunye ne-oxygen engamanzi (-183°C). Uxinzelelo loyilo: 5.0 MPa. Ibhonethi eyoluliweyo enepleyiti yokuthontsiza, esebenza ngevili lesandla.
Imingeni yoBugcisa kunye neZisombululo:
1. Ulawulo oluchanekileyo lokuhamba kwamanzi kwi -196°C ukuze imveliso icocekeIimfuneko zokucoceka kwemveliso ye-ASU (99.999% yomgangatho we-elektroniki) zifuna ulawulo oluchanekileyo lokuhamba kwamanzi. Iivalvu zeglobe ezibonelelwa yiWomic ezinezihlalo zePCTFE kunye neediski zeStellite eziqinileyo ukuze zikwazi ukuthomalalisa iimpawu ezizinzileyo. Zonke iivalvu ezili-120 ziphumelele uvavanyo lwe-cryogenic kwaye azinawo umphunga.
2. Unyango olujulileyo lwe-cryogenic kwimizimba ye-CF3M eyenziwe nge-castImizimba ye-CF3M ephosweyo isengozini yokuhlaselwa yi-austenite egciniweyo. I-Womic yenze unyango lwe-cryogenic olujikelezayo kathathu (ukuntywila kwi--196°C, iiyure ezili-12 ngomjikelo ngamnye). Ukuhlolwa kwakhona kobukhulu kuqinisekisile ukuba akukho siphazamiso.
3. Ukupakisha ukukhutshwa komoya okuncinci okubalekayo kwinkonzo yeoksijiniInkonzo yeoksijini ifuna ucoceko olungqongqo kunye nokupakisha ukungcola okuncinci. I-Womic ibonelele nge-ISO 15848-1 Class A packing enezithambiso ezihambelana neoksijini.
4. Ukuhlolwa ngumntu wesithathu yi-BVUmthengi kufuneka afumane ubungqina bovavanyo kwi-Bureau Veritas. I-BV ikhuphe izatifikethi zingadlulanga iintsuku ezili-10.
Isiphumo:Ukwandiswa kwe-ASU kuqaliswe ngempumelelo. Zonke iivalvu zeglobe ze-cryogenic eziyi-120 zisebenze kwi--196°C kangangeenyanga ezingaphezu kwe-18 ngaphandle kweziganeko zokulungiswa.
