Isishwankathelo seeNsimbi zokusika zasimahla
Iintsimbi zokusika zasimahla ezaziwa ngokuba ziintsimbi zomatshini wasimahla zezo zintsimbi zenza iitshiphusi ezincinci xa zisenziwa ngoomatshini. Oku kwandisa ukunyanzeliswa kwezinto ngokuqhekeza iitshiphusi zibe ziingceba ezincinci, ngaloo ndlela zithintele ukubanjiswa kwazo koomatshini. Oku kwenza ukuba isixhobo sisebenze ngokuzenzekelayo ngaphandle kokunxibelelana kwabantu. Iintsimbi zokusika zamahhala ezinelothe nazo zivumela amaxabiso aphezulu omatshini. Njengomthetho wesithupha, intsimbi yokusika yamahhala ngokuqhelekileyo ixabisa i-15% ukuya kwi-20% ngaphezu kwensimbi eqhelekileyo. Nangona kunjalo oku kwenziwa kukwandiswa kwezantya zoomatshini, ukusikwa okukhulu, kunye nobomi obude besixhobo.
Intsimbi yokusika yamahhala eyintsimbi ye-alloy yongezwa inani elithile le-sulfure, i-phosphorus, i-lead, i-calcium, i-selenium, i-tellurium kunye nezinye izinto zokuphucula i-machinability. Njengoko uphuhliso lobuchwephesha bomatshini, iimfuno zobuchule bentsimbi zibaluleke ngakumbi nangakumbi. Inempembelelo enkulu kwishishini.
Izicelo zentsimbi yokusika yamahhala
Ezi ntsimbi zisetyenziselwa ukuvelisa i-axles, iibholiti, izikrufu, iinati, i-shafts ekhethekileyo, i-shafts ekhethekileyo, i-forgings edibeneyo, i-forgings encinci kunye nephakathi, iingcingo ezibandayo kunye neentonga, i-rotor ye-turbine eqinile, i-rotor kunye ne-gear shaft, i-armature, i-stock stock, iifolokhwe kunye neebholiti ze-anchor. isitokhwe se-screw, iikliphu zasentwasahlobo, iityhubhu, imibhobho, iileyili ezinobunzima obulula, ukuqinisa ikhonkrithi njl.njl.
