Inkqubo Yokuvelisa Imibhobho Ye-SMLS Engenamthungo
Ukukhethwa kwezinto eziluhlaza:Intsimbi yekhabhoni esemgangathweni ophezulu ikhethwa njengezinto ezisetyenziswa kwimibhobho yentsimbi yekhabhoni engenamthungo. Umxholo wekhabhoni kwintsimbi yeyona nto ibalulekileyo ekumiseleni iimpawu zayo kunye nokufaneleka kwayo kwiindlela ezahlukeneyo zokusebenza.
Ukufudumeza nokubhoboza:Izinto eziluhlaza zifudunyezwa zifikelele kubushushu obuphezulu zize zihlatywe ukuze zenze iqokobhe elingenanto. Le nkqubo ibalulekile ekudaleni imo yokuqala yombhobho kwaye idla ngokufezekiswa ngeendlela ezifana nokubhoboza ngokujikeleza, ukukhupha, okanye ezinye iindlela ezikhethekileyo.
Ukuqengqeleka kunye nobungakanani:Iqokobhe eligqobhoziweyo lidlula kwiinkqubo zokuqengqeleka nokulinganisa ukuze kuncitshiswe ububanzi balo kunye nobukhulu bodonga lube bukhulu obufunekayo. Oku kudla ngokufezekiswa kusetyenziswa uthotho lwee-rolling mills kunye nee-saizi mills ukuze kufezekiswe imo kunye nobukhulu obufunekayo.
Unyango lobushushu:Umbhobho wentsimbi yekhabhoni ongenamthungo uphantsi kweenkqubo zonyango lobushushu ezifana nokuqhoboshela, ukulungisa, okanye ukucima kunye nokushisa ukuze kuphuculwe iimpawu zayo zoomatshini kwaye kususwe naziphi na iingcinezelo ezishiyekileyo. Unyango lobushushu lukwanceda ekufezekiseni isakhiwo esifunekayo kunye neempawu zentsimbi yekhabhoni.
Uvavanyo kunye nokuhlolwa:Kuyo yonke inkqubo yokuvelisa, umbhobho wekhabhoni ongenamthungo usebenzisa iindlela ezahlukeneyo zokuvavanya ezingatshabalalisiyo nezitshabalalisayo ukuqinisekisa ukuba uyahlangabezana nemigangatho yomgangatho efunekayo. Oku kungabandakanya uvavanyo lwe-ultrasound, uvavanyo lwe-hydrostatic, uvavanyo lwamandla e-eddy, kunye nokuhlolwa ngokubona.
Ukugqiba kunye nokwaleka:Xa umbhobho ongenamthungo uhlangabezana neemfuno ezifunekayo, udlula kwiinkqubo zokugqiba ezifana nokuwulungisa, ukuwusika, kunye nokugqiba ukuwugqiba. Ukongeza, umbhobho unokugqunywa ngezinto zokukhusela ezifana nevanishi, ipeyinti, okanye i-galvanizing ukuphucula ukumelana kwawo nokugqwala, ingakumbi kwimeko yentsimbi yekhabhoni.
Uhlolo lokugqibela kunye nokuPakisha:Umbhobho wentsimbi ogqityiweyo ongenamthungo uhlolwa okokugqibela ukuqinisekisa ukuba uyahlangabezana nayo yonke imigangatho yomgangatho kunye neemfuno zabathengi. Emva koko uyapakishwa ngononophelo kwaye ulungiselelwe ukuthunyelwa kumthengi.
Uqinisekiso loMgangatho wePipe engenamthungo ye-API 5L kunye noVavanyo
Uvavanyo lwe-hydrostatic
umbhobho ongenamthungo kufuneka umelane novavanyo lwe-hydrostatic ngaphandle kokuvuza ngomthungo we-weld okanye umzimba wombhobho.
