• I-datasheet yevalvu nemidwebo egunyaziwe
• Nikeza uhlu nokuhlobana ku-nameplate noma ithegi
• I-ITP/QAP egunyaziwe
• Imibiko yokuhlolwa kwe-MTC kanye nelebhu
• I-NDT esebenzayo kanye nezinqubo zokuhlola
• Uhlobo lokuhlolwa nokuhambisana nokuhlolwa komlilo
• Iziqu zezisebenzi ze-NDT
• Izitifiketi zokulinganisa zensimbi yokulinganisa namageji
Kwenziwa kanjani ukuhlolwa kwe-casting kanye ne-forging?
• Ukuhlolwa kwezinto ezingavuthiwe nokubuyekezwa kweshadi lokushisa
• Ukuhlonza impahla, umdwebo wesampula, nokuhlolwa kwemishini
• I-NDT: ukonakala kwendawo – I-MPI ye-fluorescent emanzi yokufoja nokusakaza
• Ukuqina kanye nokuqina kwendawo
Ukuhlolwa kanjani kweBlock, isango, imbulunga, uvemvane, isheke, namavalvu ebhola?
• Ama-castings nama-forging kumele ahlolwe
• Ukuhlolwa kokucindezela kwamavalvu kufanele kwenziwe njengegobolondo, isihlalo esingemuva, ukuvala okuphansi nokucindezela okuphezulu.
• Ukuhlolwa kokuphuma kwemfucuza
• Ukuhlolwa kwe-Cryogenic kanye nezinga lokushisa eliphansi
• Ukuhlolwa okubonakalayo nobukhulu ngokwemidwebo yedatha
Ungakwenza kanjani ukuhlolwa kwama-valve okusiza ukucindezela?
• Ukuhlolwa kokufogiwa
• Ukuhlolwa kokucindezela kwe-PSV, umzimba, nomlomo
• Ukuhlolwa okusebenzayo kwe-PSV- set pressure test, set tightness test, back pressure test.
• Ukuhlolwa okubonakalayo nokunobukhulu
Ungakwenza kanjani ukuhlolwa kokusakaza kwe-valve yokulawula?
• Umshini wokusiza olungile kufanele ufakwe
• Hlola ukuthi izilungiselelo zokucindezela zilungile yini
• Bheka noma yikuphi ukuvuza
• Igesi, izimpumputhe, amavalvu avaliwe, noma ukuvinjwa kwamapayipi akufanele kube khona
• Izigxivizo ezivikela isiphethu akumele zephulwe
• Hlola ukuthi izisetshenziswa zokusiza ziyavuza noma cha
• Ukuhlolwa kwe-ultrasonic kufanele kwenziwe
Ungaqinisekisa kanjani ukuphepha ngesikhathi sokuhlolwa kwama-valve okulawula?
• Ngaphambi kokuba sisuse ivalvu emugqeni leyo ngxenye yolayini equkethe ivalvu kufanele ivalwe kuyo yonke imithombo yoketshezi oluyingozi, amagesi, noma umhwamuko.Ngakho le ngxenye yomugqa kufanele icindezeleke futhi isuswe kuwo wonke uwoyela, amagesi anobuthi, noma amagesi avuthayo.Ithuluzi lokuhlola kufanele lihlolwe ngaphambi kokuhlolwa.
Indlela yokwenza ukuhlolwa kwe-valve enesici?
• Hlola ilogu lokuhlola isitshalo futhi uhlole nokuhlolwa kwempahla ukuze kutholakale izimpawu zokungasebenzi kwamavalvu
• Izinto ezilungisiwe zesikhashana kufanele zisuswe njengezinsimbi, amapulaki, njll.
• Hlola i-valve ukuthi ayinamonakalo yini noma ukugqwala
• Hlola amabhawodi namantongomane ukuthi akugqwalile yini
• Hlola ukuthi indawo eyakhiweyo inogqinsi olufanele futhi uhlole nekhwalithi yomzimba wevalvu
• Hlola ukuthi isango noma idiski ivikelwe kahle yini esiqwini
• Iziqondiso ezisesangweni nasemzimbeni kumele zibhekwe ukuthi azigqwalile yini
• Kufanele sihlole umlandeli we-gland, uma umlandeli elungiswa yonke indlela yehla kuyodingeka ukupakisha okwengeziwe
• Hlola ukuthi ivalvu ingasetshenziswa kalula uma kungenjalo, khona-ke ukupakisha kungase kudingeke kushintshwe
Indlela yokuhlola i-valve yokulawula eyakhelwe kabusha noma elungisiwe?
• Uma izingxenye zevalvu zishintshwa qinisekisa ukuthi zifakiwe yini izingxenye ezifanele
• Kufanele futhi sihlole ukuthi impahla yokunquma yevalvu ilufanele yini uhlobo lwesevisi
• Kufanele senze i-hydro-test ukuze sithole ukuthi ivalvu ekhandiwe ikulungele yini ukusebenza
• Ukuhlolwa okuqinile kwesihlalo kufanele kwenziwe kuvalvu edinga ukuvaleka ngci uma ukugunda kulungisiwe noma kushintshiwe
• Uma i-gasket kanye nokupakishwa kuvuselelwe kufanele kwenziwe ukuhlolwa kokuqina
