Imibuzo Ebuzwa Rhoqo (FAQ)
Ukujongana nemibuzo eqhelekileyo kunceda ukucacisa ukungaqiniseki malunga neebholithi zeenqwelo kunye nenkqubo yokuthengwa kwempahla. Ezi mpendulo zisekelwe kwimigangatho yoshishino kunye namava asebenzayo ukusuka kwimisebenzi yefektri.
Yintoni umahluko phakathi kwebholithi yenqwelo kunye nehex bolt?
Umahluko ophambili ulele kwimilo yentloko kunye nendlela yokutshixa. Ibholithi yenqwelo inentloko yedome egudileyo kunye nentamo yesikwere evalela kwizinto eziphathekayo, ukuthintela ukujikeleza. I-hex bolt inentloko enamacala amathandathu eyenzelwe ukubanjwa sisikrweqe kwaye ayinayo intamo yesikweri ezivalelayo. Iibholiti zokuthwala zikhethwa kwizicelo zokhuni apho kufuneka ukugqiba okugudileyo, ngelixa iibholiti ze-hex zisetyenziselwa ukudibanisa isinyithi ukuya kwintsimbi apho i-torque ephezulu ifakwe entloko.
Ngaba iibholithi zekhareji zingasetyenziswa kwi-metal-to-metal applications?
Ewe, kodwa ngokusikelwa umda. Ekubeni intamo yesikwere ixhomekeke ekulumeni kwizinto eziphathekayo ukukhusela ukujikeleza, ayikwazi ukuzitshixa kwintsimbi eqinile. Ukusetyenziswa kwesinyithi ukuya kwintsimbi, icandelo lesikwere kufuneka lifake kwimbobo yesikwele ehambelanayo ephontywe okanye ifakwe kwintsimbi, okanye intloko ye-bolt kufuneka ibanjwe nge-wrench ngexesha lofakelo. Kungenjalo, i-serrated flange nuts ingasetyenziselwa ukuthintela ukujikeleza ukusuka kwicala le nut.
Ndibubona njani ubude obuchanekileyo bebholi yenqwelo?
Ubude bebholithi yenqwelo bulinganiswa ukusuka ngaphantsi kwentloko ukuya kwincam yemisonto, ngaphandle kwentloko ngokwayo. Ukumisela ubude obuchanekileyo, linganisa ubukhulu obupheleleyo bezinto ezidityanisiweyo, yongeza ubukhulu bewasha kunye ne-nut, kwaye ubandakanye imisonto eyongezelelweyo ye-1-2 eyongezelelweyo idlula i-nut ukwenzela ukudibanisa okufanelekileyo. Ungaze ukhethe ibholiti emfutshane kakhulu, njengoko ukungonelanga kokudibana komsonto kubeka esichengeni amandla.
Ngaba iibholithi zekhareji zentsimbi yomelele kunezentsimbi?
Ngokuqhelekileyo, akukho. Iibholiti zentsimbi eziqhelekileyo (i-304/316) ngokuqhelekileyo zinamandla angaphantsi obunzima xa kuthelekiswa neBanga lesi-5 okanye iBanga lesi-8 lebholiti yentsimbi. Intsimbi engenastainless ikhethwa ngenxa yokumelana nomhlwa, hayi amandla ayo okugqibela. Ukuba amandla aphakamileyo afunekayo kwindawo enobungozi, i-alloys ekhethekileyo yamandla angenasici okanye i-coated high-grade bolts kufuneka ithathelwe ingqalelo.
Zeziphi iinketho zokugqiba ezikhoyo zokukhusela umhlwa?
Ngaphandle kwentsimbi ecacileyo kunye nentsimbi engatyiwayo, kukho iindlela ezininzi zokwaleka. I-Zinc plating (ecacileyo okanye etyheli) inika ukhuseleko olusisiseko kusetyenziso lwangaphakathi. I-Hot-dip galvanizing ibonelela nge-zinc etyebileyo yokugquma ngokufanelekileyo kwizakhiwo zangaphandle kunye neepali eziluncedo. Iingubo zeGeomet kunye neDacromet zibonelela ngokumelana nomhlwa okungaphezulu ngaphandle kokwakhiwa okushinyeneyo kwegalvanizing eshushu, ezenza zilungele iindibano ezichanekileyo. Ukhetho luxhomekeke kwi-exposure ethile yokusingqongileyo.
