EYurophu, ukuba ufuna ukuthengisa okanye ukufaka nayiphi na inkqubo ye-cryogenic, kufuneka uhlangabezane neemfuno zokumakisha ze-CE ezimiselwe yiPressure Equipment Directive (PED 2014/68/EU). I-PED iyasebenza kuyo nayiphi na isixhobo okanye indibano enoxinzelelo oluphezulu oluvumelekileyo olungaphezulu kwe-0.5 bar. Ngoko ke, phantse yonke inkqubo ye-cryogenic yemizi-mveliso—nokuba yi-Umbhobho ogqunywe nge-vacuuminethiwekhi okanyeUmbhobho oguquguqukayo ogqunywe nge-vacuum—kufuneka ithobele. Akukho ndlela yokuphepha loo nto ukuba usebenza kwi-EU.
I-PED yahlulahlula izixhobo zibe ziindidi, kuxhomekeke kwizinto ezifana noxinzelelo, umthamo, kunye nokuba ulwelo luyingozi kangakanani. Udidi ngalunye luza noluhlu lwalo lwezinto ekufuneka zenziwe ukuze kufunyanwe isiqinisekiso. Ungadinga umbutho onolwazi ukuze ujonge umsebenzi wakho, udlule kuvavanyo lohlobo, okanye umisele inkqubo yokuqinisekisa umgangatho evunyiweyo. Xa sijongene nento efana neyethuIvalvu Egqunywe NgomoyaokanyeIsahluli seSigaba esifakwe i-Vacuums, ukuthobela i-PED kuthetha ukuba kufuneka ubuyisele umva izibalo zakho zoxinzelelo, wenze uvavanyo lwe-hydrostatic kunye ne-pneumatic, uqinisekise ukuba izixhobo ziyalandeleka, kwaye uphumelele uvavanyo lokugqibela lokuhambelana.
Kukho okungakumbi, nangona kunjalo. I-PED ayisiyonto yodwa ekufuneka uyilandele. Imigangatho ye-Harmonized EN ixhomekeke kwimithetho ethile yobugcisa. I-EN 12501 ichaza iimfuno zezinto ezifunekayo kumaqondo obushushu aphantsi. I-EN 13648 igubungela izixhobo zokhuseleko kwiisetingi ze-cryogenic.

Isizathu soBunjineli emva kweeMfuno zeSatifikethi
Iziqinisekiso azikho uluhlu lokujonga olungenanjongo—zisekelwe kwimigaqo yobunjineli esisiseko echaphazela ngokuthe ngqo ukusebenza kwenkqubo kunye nokhuseleko. Cinga ngeendlela ezintathu eziphambili zokudlulisa ubushushu: ukuqhuba, ukuhambisa ubushushu, kunye nokukhanya.Umbhobho ogqunywe nge-vacuumokanye ipayipi ye-cryogenic, i-vacuum annulus ephakathi kwemibhobho yangaphakathi neyangaphandle isusa ngokupheleleyo ukudluliselwa kobushushu obujikelezayo, inciphisa ukuvuza kobushushu ngokubanzi ngaphezu kwe-90% xa kuthelekiswa nemibhobho eqhelekileyo egqunyiweyo. Oku kuncipha okukhulu kokungena kobushushu kuthetha ngokuthe ngqo kumazinga aphantsi okubila, iindleko zokusebenza ezinciphileyo, kunye namaqondo obushushu enkqubo azinzileyo.
Nangona kunjalo, ukugcina loo vacuum ngokuhamba kwexesha kuyingxaki. Nokuba ukuvuza okuncinci okanye ukuphuma kwegesi kwizinto zangaphakathi kunokonakalisa ukusebenza kwe vacuum kancinci kancinci. Kulapho keInkqubo yePompo yeDynamic Vacuumiyasebenza. Ngokungafaniyo neenkqubo zokukhupha umoya ezingasebenziyo eziwohlokayo ngokuhamba kwexesha, inkqubo yethu enamandla iqhubeka nokukhupha iigesi ezilandelelanayo kwi-annulus, igcina ingqibelelo yokukhupha umoya kuyo yonke imisebenzi yenkqubo. Le ndlela esebenzayo yolawulo lokukhupha umoya yeyona nto ibalulekileyo eyaziwayo ziinkampani zeziqinisekiso—kwaye yingakho iinkqubo zethu zihlala ziphumelela uvavanyo olunzima lokusebenza lwexesha elide.
Ukukhethwa kwezinto zezixhobo yenye indawo apho iimfuno zesatifikethi ziqhuba ukugqwesa kobunjineli. Kumaqondo obushushu aphantsi, uninzi lweentsimbi eziqhelekileyo ziba buthathaka kwaye ziqhekezeke lula. Sichaza iintsimbi ezingenasici ze-austenitic ezifana ne-304L kunye ne-316L kwiipayipi zethu zangaphakathi kuba zigcina ukuqina kunye nokumelana nokugqwala nokuba kukwi--269°C. Iijakethi zethu zangaphandle zikhethwa ngokusekelwe kwiimeko zendalo ezithile zeprojekthi—ukufakelwa konxweme kunokufuna ukhuseleko oluphuculweyo lokugqwala, ngelixa ukufakelwa kwentlango kunokubeka phambili ukumelana ne-UV.
Ukuncitshiswa kobushushu yenye into ebalulekileyo ekufuneka iqwalaselwe. Xa inkqubo yokudlulisa i-cryogenic iphola ukusuka kubushushu obuqhelekileyo ukuya kubushushu bokusebenza, imibhobho iyancipha kakhulu. Ukuba amalungu okwandisa, ukugoba, okanye iindawo eziguquguqukayo azakhiwanga kakuhle, oku kuncitshiswa kunokubangela uxinzelelo olutshabalalisayo.Umbhobho oguquguqukayo ogqunywe nge-vacuumIimveliso zenzelwe ngokukodwa ukulungelelanisa ezi ntshukumo, zibonelela ngokuhlukaniswa kobushushu kunye nokuguquguquka koomatshini kwindibano enye edibeneyo.
