Yini okufanele ngiyiqaphele lapho ngihlola amathangi okugcina uketshezi oluyi-cryogenic?

Ukuhlolwa kwethangi lokugcina uketshezi oluyi-cryogenic kuhlukaniswe ukuhlolwa kwangaphandle, ukuhlolwa kwangaphakathi kanye nokuhlolwa okunezinhlangothi eziningi. Ukuhlolwa okwenziwa ngezikhathi ezithile kwamathangi okugcina uketshezi oluyi-cryogenic kufanele kunqunywe ngokwemibandela yobuchwepheshe yokusetshenziswa kwamathangi okugcina.

 Ngokuvamile, ukuhlolwa kwangaphandle kwenziwa okungenani kanye ngonyaka, ukuhlolwa kwangaphakathi kwenziwa okungenani kanye eminyakeni emi-3, kanti ukuhlolwa okunezinhlangothi eziningi kwenziwa okungenani kanye eminyakeni eyi-6. Uma ithangi lokugcina izinto lokushisa eliphansi liphila iminyaka engaphezu kwengu-15, ukuhlolwa kwangaphakathi nangaphandle kufanele kwenziwe njalo eminyakeni emibili. Uma impilo yokusebenza iyiminyaka engama-20, ukuhlolwa kwangaphakathi nangaphandle kufanele kwenziwe okungenani kanye ngonyaka.

1. Ukuhlolwa kwangaphakathi

 1). Kungakhathaliseki ukuthi kukhona ukuguguleka okugqwalayo ebusweni bangaphakathi kanye nethangi lokugcina lokuxhumanisa imbobo, nokuthi ngabe kukhona imifantu emthungweni wokushisela, indawo yokuguquka kwekhanda noma ezinye izindawo lapho ukucindezeleka kugxile khona;

 2). Uma kukhona ukugqwala ezindaweni zangaphakathi nezangaphandle zethangi, kufanele kwenziwe izilinganiso eziningi zobukhulu bodonga ezingxenyeni ezisolwayo. Uma ubukhulu bodonga obulinganisiwe bungaphansi kobukhulu bodonga obuncane obuklanyiwe, ukuqinisekiswa kwamandla kufanele kuhlolwe kabusha, futhi kuphakanyiswe iziphakamiso zokuthi ingaqhubeka yini isetshenziswe kanye nomfutho ophezulu ovumelekile wokusebenza;

 3). Uma udonga lwangaphakathi lwethangi luneziphambeko ezifana nokususwa kwekhabhoni, ukugqwala kokucindezeleka, ukugqwala okuphakathi kwe-granular kanye nemifantu yokukhathala, ukuhlolwa kwe-metallographic kanye nokulinganiswa kobulukhuni bomphezulu kufanele kwenziwe, bese kuhanjiswa umbiko wokuhlola.

2. Ukuhlolwa kwangaphandle

 1). Hlola ukuthi ungqimba olulwa nokugqwala, ungqimba lokuvikela kanye ne-nameplate yemishini yethangi lokugcina izinto ziphelele yini, nokuthi izesekeli zokuphepha namadivayisi okulawula aphelele, azwela futhi athembekile yini;

 2). Kungakhathaliseki ukuthi kukhona imifantu, ukuguquka, ukushisa ngokweqile kwendawo, njll. ebusweni obungaphandle;

 3). Kungakhathaliseki ukuthi umthungo wokushisela wepayipi elixhumanisayo kanye nezingxenye zokucindezela kuyavuza, kungakhathaliseki ukuthi amabhawodi okubopha aphelele, kungakhathaliseki ukuthi isisekelo siyacwila, siyathambekela noma ezinye izimo ezingavamile.

3, Ukuhlolwa okuphelele

 1). Yenza ukuhlolwa okungenamonakalo ku-weld noma igobolondo eliyinhloko, futhi ubude bokuhlola indawo kufanele bube ngu-20% wobude obuphelele be-weld;

 2). Ngemva kokudlula ukuhlolwa kwangaphakathi nangaphandle, yenza ukuhlolwa kwe-hydraulic ngokuphindwe ka-1.25 kwengcindezi yokuklama yethangi lokugcina kanye nokuhlolwa komoya okungenamoya ngengcindezi yokuklama yethangi lokugcina. Enqubweni yokuhlola engenhla, ithangi lokugcina kanye nama-weld azo zonke izingxenye akunawo ukuvuza, futhi ithangi lokugcina alinawo ukuguquguquka okungavamile okubonakalayo njengoba kufanele;

 Ngemva kokuba ukuhlolwa kwethangi lokugcina izinto elisezingeni eliphansi lokushisa sekuqediwe, kufanele kwenziwe umbiko ngokuhlolwa kwethangi lokugcina izinto, okubonisa izinkinga nezizathu ezingasetshenziswa noma ezingasetshenziswa kodwa ezidinga ukulungiswa futhi ezingeke zisetshenziswe. Umbiko wokuhlola kufanele ugcinwe efayeleni ukuze kugcinwe ukulungiswa nokuhlolwa esikhathini esizayo.
