Malangizo Okhazikitsa
VJP(mapaipi opangidwa ndi vacuum jekete)ziyenera kuyikidwa pamalo ouma opanda mphepo musanaziike.Theyakunjakulongedzagawo la VJP silingathebe tsegulanied, kuteteza chubucho kuti chisalowe m'zinthu zakunja (mchenga, tizilombo tating'onoting'ono, ndi zina zotero). Mu mvula kapena nthawi yayitalichonyowanyengo, muyeneranso kusamala kwambiri mkati mwa payipi kuti madzi asalowe.
Ndikoletsedwa kugwiritsa ntchito VJP mwachindunji ngati electrode yolumikizira, mzere wogundakapena kuwotcherera pa VJP.
VJPkulongedzawosanjikiza sungachotsedwe mpaka chitolirocho chitayikidwa kuti chiteteze kuwonongeka kwa kuwotcherera m'malo ena.
Pa nthawi yonse yokhazikitsa, VJP iyenera kusamalidwa mosamalaTetezani mbali zonse ziwiriya VJP, musagwiritse ntchitochotsukira mpweyacholumikizira pa VJP (chithunzi 1 ndi 3) ngati mfundo ya mphamvu yopewera kutuluka kwa vacuum.
Mukakhazikitsa, samalani ndi kudalirika kwa kukweza, musagwe ndi kuwonongeka kapena kuvulala.

Tsatanetsatane wa Ntchito ndi Kukonza
1. Ogwira ntchito ayenera kudziwa bwino zantchitokuyendas pakati pa zida zomwe zili mu dongosololi. Tiyenera kudziwa kuti mpweya wamadzimadzi, nayitrogeni wamadzimadzi ndi argon wamadzimadzi ndi zakumwa zoziziritsa kukhosi. Pamene kutentha kwa mlengalenga kuli kokwera kuposa kutentha, zimakhala zachilengedwe.gasifyndi kupanikizika, zomwe zimapangitsa kuti kupanikizika kuchuluke pang'onopang'onoVJP ndi zina zokhudzana nazozida.
2. Kuziziritsa VJP musanagwiritse ntchito
Popeza VJP yosagwiritsidwa ntchito ili pa kutentha kozungulira, chitolirocho chimadzazidwa ndi mpweya womwe uli ndi chinyezi. Chifukwa chake, cholinga choziziritsira chisanadze ndi: choyamba, kuchepetsa pang'onopang'ono kutentha kwa VJP kufika pa kutentha kwa madzi a cryogenic, kuti apewe kukhudzana mwachindunji ndi madzi ambiri a cryogenic ndi chitoliro chotentha chanthawi zonse, zomwe zimapangitsa kuti mpweya ukhale wambiri komanso wochuluka, zomwe zimapangitsa kuti VJP iyambe kupanikizika mwachangu, zomwe zimapangitsa kuti VJP iwonongeke ndi zida zamadzimadzi za terminal. Chachiwiri, ndikuchotsa pang'onopang'ono mpweya mkati mwa VJP ndikupewa madzi ambiri a cryogenic kukhudzana mwachindunji ndi mpweya, zomwe zimapangitsa kuti VJP izizizira komanso kutsekeka.
Musanayambe kugwiritsanso ntchito chitoliro cha vacuum adiabatic pambuyo pa kugwiritsa ntchito koyamba kapena kuyimitsa kupanga, kuziziritsa kuyenera kuchitika kuti chitoliro cha vacuum adiabatic chizigwira ntchito bwino pokhapokha chikafika pamalo ogwirira ntchito.
