Kwenziwa njani uhlolo lokuphosa kunye nenkohliso?
• Uhlolo lwemathiriyeli ekrwada kunye nophononongo lwetshathi yobushushu
• Ukuchongwa kwezinto, umzobo wesampulu, kunye novavanyo lomatshini
• I-NDT: iziphene zomphezulu – iMPI yefluorescent emanzi yokubumba nokusasa
• Ukuqina kunye noburhabaxa bomphezulu
Kwenziwa njani uhlolo lweBloko, isango, iglowubhu, ibhabhathane, itshekhi, kunye neevalvu zebhola?
• Iisamente kunye nezinto ezenziweyo kufuneka zihlolwe
• Uvavanyo loxinzelelo lweevalvu kufuneka lwenziwe njengeqokobhe, isitulo esingasemva, ukuvaleka okuphantsi kunye noxinzelelo oluphezulu.
• Uvavanyo lokuphuma ngaphandle
• Uvavanyo lweCryogenic kunye nobushushu obuphantsi
• Uhlolo olubonakalayo kunye nobukhulu ngokwemizobo yedatha
Unokwenza njani ukuhlolwa kweevalve zokunciphisa uxinzelelo?
• Ukuhlolwa kweefogi
• Uvavanyo loxinzelelo lwe-PSV, umzimba, kunye nomlomo
• Uvavanyo olusebenzayo lwe-PSV- set pressure test, set tightness test, back pressure test.
• Uhlolo olubonakalayo kunye nolunemilinganiselo
Kwenziwa njani uphononongo lomlambo wevalve yolawulo?
• Kufuneka kufakwe isixhobo sokunceda esichanekileyo
• Jonga ukuba useto loxinzelelo lufanelekile na
• Khangela nakuphi na ukuvuza
• Irhasi, iimfama, iivalvu ezivaliweyo, okanye ukuvaleka kwemibhobho akufuneki kubekho
• Amatywina akhusela intwasahlobo kufuneka angaqhawuki
• Jonga ukuba izixhobo zokunceda ziyavuza okanye azivuzi
• Uvavanyo lwe-ultrasonic kufuneka lwenziwe
Indlela yokuqinisekisa ukhuseleko ngexesha lokuhlolwa kweevalvu zokulawula?
• Phambi kokuba sisuse isivalo emgceni elo candelo lomgca oqulethe isivalo kufuneka livalwe kuyo yonke imithombo yolwelo oluyingozi, iirhasi, okanye umphunga.Ke le ndawo yomgca kufuneka icinezeleke kwaye icocwe kuyo yonke ioyile, ityhefu, okanye iigesi ezinokutsha.Isixhobo sokuhlola kufuneka sihlolwe phambi kokuhlolwa.
Ukwenza njani ukuhlolwa kwevalve enesiphene?
• Qwalasela isigcini sokuhlolwa kweplanti kwaye ujonge nokuhlolwa kwesixhobo ukuze kubonwe iimpawu zokusilela kwevalvu
• Izinto ezilungiswayo zexeshana kufuneka zisuswe njengezibamba, iiplagi, njl.
• Jonga ivalve ukuba akukho monakalo kumatshini okanye ukudleka
• Qwalasela iibholithi kunye namandongomane ukuba akukho mhlwa na
• Jonga ukuba indawo eyakhiweyo inobungqingqwa obufanelekileyo kwaye ujonge nomgangatho womzimba wevalvu
• Jonga ukuba isango okanye idiski ikhuselwe ngokufanelekileyo kwisiqu
• Izikhokelo kuzo zombini isango kunye nomzimba kufuneka zikhangelwe ukuthotywa
• Kufuneka sijonge umlandeli wedlala, ukuba umlandeli ulungelelaniswe yonke indlela ukuya ezantsi kuya kufuneka ukupakisha okongeziweyo
• Khangela ukuba ivalve inokusebenza ngokulula ukuba akunjalo ngoko ke ukupakishwa kungafuna ukutshintshwa
Indlela yokuhlola ivalve yokulawula eyakhiwe ngokutsha okanye elungisiweyo?
• Ukuba iindawo zesivalo zitshintshiwe qinisekisa ukuba iindawo ezichanekileyo zifakelwe na
• Kufuneka kwakhona sijonge ukuba i-trim material yevalvu ilufanele na uhlobo lwenkonzo
• Kufuneka senze uvavanyo lwe-hydro ukuze siqonde ukuba isivalo esilungisiweyo sikulungele na ukusebenza
• Uvavanyo lwesitulo kufuneka lwenziwe kwivalvu efuna ukuvalwa ngci ukuba isitrim silungisiwe okanye sitshintshwe
• Ukuba i-gasket kunye nokupakishwa kuhlaziywe ngoko uvavanyo lokuqina kufuneka lwenziwe
