Ezinye iirekhodi zemveliso yezixhobo zevalvu
Xa ufumana imibuzo okanye imizobo enxulumene neevalvu emsebenzini wemihla ngemihla, impendulo yokuqala yabantu abaninzi kukujonga umlinganiselo woxinzelelo, ububanzi kunye nomgangatho. Nangona kunjalo, xa kufikwa kwimveliso yokwenyani, uninzi lweengxaki luvela kwizixhobo zeevalvu endaweni yesakhiwo sevalvu ngokwaso.
Kwimveliso yokwenyani, iingxaki ezihlala zibikwa kwindawo azizo iimpazamo zoyilo kodwa zinxulumene nezinto ezithile zevalvu yemizi-mveliso. Ezona zixhaphakileyo zizinto ezifana ne umzimba wevalvu, isiqu sevalvu, isihlalo sevalvu, kunye nebhola yevalvu, ezifuna ukucutshungulwa nokuhlanganiswa ngokuphindaphindiweyo.
Thatha umzimba wevalvu njengomzekelo. Emva kokucubungula, intsimbi yekhabhoni kunye nentsimbi engatyiwayo azibonakali zahlukile kangako, kodwa umahluko uya kuvela kancinci emva kwexesha lokusetyenziswa. Ukuchaneka komsonto, ukuba tyaba komphezulu wokutywina, kunye nemeko yokucubungula indawo yokugubungela ivalvu konke kuya kuba nefuthe ekusebenzeni kamva. Ezi zinto zisenokungachazwa ngokweenkcukacha kwimizobo, kodwa ziyandiswa ngokulula xa zisetyenziswa ngokwenene.
Iingxaki ngesiqu sevalvu nazo zihlala zingahoywa. Ezinye iziqu zevalvu zinobukhulu obufanelekileyo, kodwa ukuba uburhabaxa bomphezulu abulawulwa kakuhle, ukuvuza kwindawo yokupakisha kunokwenzeka phantsi kweemeko zokuvula nokuvala rhoqo. Ezi ngxaki zisenokungabonwa kwangoko ngexesha lokuhlanganiswa kwaye zihlala zibonakala kuphela emva kokuba ivalvu isebenze ixesha elithile.
Ngokuphathelele izixhobo, A105, LF2, CF8M, kunye ne-316L zonke ziqhelekile kwiindawo zeevalvu zoshishino. Nangona kunjalo, ezinye iiprojekthi zinokuba neemfuno ezongezelelweyo EN 10204 3.1 izatifikethi zezinto eziphathekayo okanye ukuthobela Imigangatho ye-NACEKwiimeko ezinjalo, ulawulo lwezinto azipheleli nje ekukhupheni uxwebhu, kodwa luqhuba yonke inkqubo yokuvelisa.
Ngokuphathelele iindlela zokuvelisa, izixhobo zevalvu ezibunjiweyo zihlala zisetyenziswa kwiimeko zokusebenza ezikumgangatho ophezulu, ikakhulu ngenxa yokuzinza kolwakhiwo lwazo kunye namandla azo. Ii-castings zisasetyenziswa kwiiprojekthi ezininzi. Lo gama nje ulawulo lwenkqubo lukhona, zinokuhlangabezana neemfuno.
Ukuhambelana komatshini wokugaya we-CNC kubaluleke kakhulu kwiiprojekthi ze-OEM. Ukuba kukho ukuphambuka kwimisonto, ukutywina umphezulu kunye nobukhulu bokudibana kweebhetshi ezahlukeneyo, iingxaki ziya kubakho ngexesha lokuhlanganiswa. Kwizixhobo zevalvu ze-OEM, nokuba zinokuhlanganiswa ngokuthe ngqo kwaye zisetyenziswe kudla ngokuba kubaluleke ngakumbi kunembonakalo.
Ngokwembono yemveliso, eyona nzuzo inkulu yokusebenzisana nomenzi wezixhobo zevalvu ezizinzileyo kukunciphisa utshintsho oluphindaphindwayo. Unxibelelwano olucacileyo lwemizobo kunye namanqaku obuchwephesha kwinqanaba lokuqala ludla ngokuba luncinci kakhulu kunokuphinda ulusebenzise kamva.
Ezi nkcukacha zisenokungabonakali kwimbonakalo yevalvu egqityiweyo, kodwa xa ivalvu ifakiwe kwaye iqalisiwe ukusebenza, umgangatho wezixhobo zevalvu uza kubonakala kungekudala.
