Ndiyenera kusamala chiyani ndikamayang'anira akasinja osungira madzi a cryogenic?

Kuwunika kwa tanki yosungiramo madzi a Cryogenic kumagawidwa pakuwunika kwakunja, kuyang'anira mkati ndi kuwunika kosiyanasiyana.Kuwunika kwanthawi ndi nthawi kwa akasinja osungira a cryogenic kudzatsimikiziridwa molingana ndi luso logwiritsa ntchito akasinja osungira.

 Nthawi zambiri, kuyang'ana kunja kumachitika kamodzi pachaka, kuyang'ana kwamkati kumachitika kamodzi pazaka zitatu zilizonse, ndipo kuwunika kosiyanasiyana kumachitika kamodzi pazaka 6 zilizonse.Ngati thanki yosungiramo kutentha yotsika imakhala ndi moyo wautumiki wa zaka zoposa 15, kuyang'anitsitsa mkati ndi kunja kudzachitika zaka ziwiri zilizonse.Ngati moyo wautumiki ndi zaka 20, kuyang'anira mkati ndi kunja kudzachitika kamodzi pachaka.

1. Kuyendera mkati

 1).Kaya pali zovala zowononga pamtunda komanso thanki yosungiramo mahole, komanso ngati pali ming'alu mumsoko wowotcherera, malo osinthira mutu kapena malo ena omwe kupsinjika kumakhazikika;

 2).Pamene pali dzimbiri mkati ndi kunja kwa thanki, miyeso ingapo ya makulidwe a khoma iyenera kuchitidwa pazigawo zomwe zikuganiziridwa.Ngati makulidwe a khoma loyezedwa ndi ochepa kuposa makulidwe ang'onoang'ono opangidwa ndi khoma, kutsimikizika kwamphamvu kuyenera kuyang'aniridwanso, ndi malingaliro oti apitilize kugwiritsidwa ntchito komanso kukakamizidwa kwakukulu kovomerezeka kuyenera kuperekedwa patsogolo;

 3).Pamene khoma lamkati la thanki lili ndi zolakwika monga decarburization, corrosion stress, intergranular corrosion ndi ming'alu ya kutopa, kuyang'ana kwa metallographic ndi kuyeza kuuma kwa pamwamba kudzachitika, ndipo lipoti loyendera lidzaperekedwa.

2. Kuyendera kunja

 1).Onani ngati anti-corrosion layer, insulation layer ndi nameplate ya zida za thanki yosungirako zili bwino, komanso ngati zida zachitetezo ndi zida zowongolera zili zonse, zomveka komanso zodalirika;

 2).Kaya pali ming'alu, mapindikidwe, kutentha kwapakati, etc. kunja;

 3).Kaya msoko wowotcherera wa chitoliro cholumikizira ndi zigawo zokakamiza zikutha, kaya mabawuti omangirira ali osasunthika, kaya maziko akumira, akupendekeka kapena zovuta zina.

3, Kuyendera kwathunthu

 1).Chitani kuyendera kosawonongeka pa chowotcherera chachikulu kapena chipolopolo, ndipo kutalika kwa cheke kudzakhala 20% ya kutalika konse kwa weld;

 2).Pambuyo podutsa zowunikira zamkati ndi zakunja, chitani mayeso a hydraulic pa 1.25 nthawi ya kukakamiza kwa kapangidwe ka tanki yosungiramo komanso kuyesa kwa mpweya pamapangidwe a tank yosungira.Pakuwunika pamwambapa, tanki yosungiramo ndi ma welds a magawo onse alibe kutayikira, ndipo tanki yosungira ilibe mawonekedwe owoneka bwino omwe ali oyenerera;

 Pambuyo poyang'anitsitsa tanki yosungiramo kutentha kwapansi kumalizidwa, lipoti liyenera kuperekedwa pakuyang'anira tanki yosungiramo, kusonyeza mavuto ndi zifukwa zomwe zingagwiritsidwe ntchito kapena zomwe zingagwiritsidwe ntchito koma ziyenera kukonzedwa ndipo sizingagwiritsidwe ntchito.Lipoti loyendera liyenera kusungidwa pafayilo kuti lizikonzedwanso ndikuwunikanso.
