Umbhobho wentsimbi
Inkcazelo emfutshane:
Umbhobho wentsimbi ubhekiselele kumbhobho ophoswe ngentsimbi.Umbhobho wentsimbi usetyenziselwa unikezelo lwamanzi, imibhobho yokuhambisa amanzi kunye nemibhobho yokuhambisa igesi, kubandakanywa imibhobho yentsimbi etyhidiweyo kunye nezifakelo zemibhobho.Amandla okusebenza aphantsi.Ngokweendlela ezahlukeneyo zokugalela, yahlulwe yaba ngumbhobho wentsimbi oqhubekayo kunye nombhobho wentsimbi we-centrifugal, apho umbhobho wentsimbi we-centrifugal wahlulwe ube ngundo lwesanti kunye nokungunda kwesinyithi.Ngokwezixhobo ezahlukeneyo, yahlulahlulwe ibe yintsimbi engwevu yombhobho kunye nombhobho wentsimbi.Ngokweefom ze-interface ezahlukeneyo, yahlulwe ibe yi-flexible interface, i-interface ye-flange, i-self-anchor interface, i-interface eqinile, njl.

Isiseko sombhobho wentsimbi yi-ductile iron pipe, ebizwa ngokuba yi-iron nature kunye nokusebenza kwentsimbi.Igraphite kumbhobho wentsimbi ye-ductile ikhona kwifom ye-spherical, kwaye ubungakanani begraphite ngokubanzi yi-6-7.Umgangatho ufuna ukuba umgangatho we-spheroidization wombhobho wentsimbi ulawulwe kwinqanaba le-1-3, kwaye izinga le-spheroidization liyi-≥80%, ngoko ke iimpawu zomatshini wezinto eziphathekayo ziphuculwe kakuhle, kunye nobume bentsimbi kunye nokusebenza kwentsimbi. .Emva kwe-annealing, i-metallographic ye-metallographic ye-ductile iron pipe yi-ferrite kunye nexabiso elincinci le-pearlite, kunye neempawu zomatshini zilungile, ngoko ke ikwabizwa ngokuba ngumbhobho wentsimbi.
