Yintoni umahluko phakathi kombhobho wesinyithi othambileyo nombhobho wesinyithi oqhelekileyo?

1. Iingcamango ezahlukeneyo
Umbhobho wesinyithi owenziwe ngomatshini ngumbhobho wesinyithi onomjelo womjelo oguquguqukayo owenziwe yinkqubo yokusika i-centrifugal. I-interface ngokubanzi iluhlobo lwe-clamp yohlobo lwe-W okanye uhlobo lwesokhethi yeflange yohlobo lwe-A.

Iipayipi zesinyithi ezithambileyo zibhekisa kwiipayipi eziphoswa nge-centrifugal casting ekhawulezayo kusetyenziswa umatshini wesinyithi othambileyo othambileyo ophakathi emva kokongeza i-nodulizing agent kwisinyithi esinyibilikisiweyo ngaphezulu kweNombolo 18. Zibizwa ngokuba ziipayipi zesinyithi ezithambileyo, iipayipi zesinyithi ezithambileyo kunye neepayipi ezithambileyo. Isetyenziswa kakhulu ekuthuthweni kwamanzi empompini, sisixhobo esifanelekileyo kwiipayipi zamanzi empompini.

2. Ukusebenza okwahlukileyo
Umbhobho wesinyithi oxutyiweyo luhlobo lwesinyithi esixonxiweyo, i-alloy yesinyithi, ikhabhoni kunye ne-silicon. I-Graphite kwisinyithi esixonxiweyo ikhona ngohlobo lwe-spheroids. Ngokubanzi, ubungakanani be-graphite bukwibanga lesi-6-7. Umgangatho ufuna ukuba umgangatho we-spheroidization wombhobho oxutyiweyo ulawulwe ukuya kwibanga loku-1-3, ukuze iipropati zoomatshini zezinto ngokwazo ziphuculwe ngcono. Inentsingiselo yesinyithi kunye neepropati zentsimbi. Ulwakhiwo lwe-metallographic lombhobho wesinyithi oxutyiweyo yi-ferrite kunye nenani elincinci le-pearlite, kwaye iipropati zayo zoomatshini zilungile.

Ubomi benkonzo yeepayipi zesinyithi ezenziwe ngomatshini budlula ubomi obulindelekileyo besakhiwo. Inokumelana okuhle kakhulu nokunyikima kwaye ingasetyenziselwa ukukhusela izakhiwo eziphakamileyo. Isebenzisa ii-flange glands kunye neeringi zerabha okanye iiringi zerabha ezifakwe uphahla kunye nee-clamps zentsimbi engatyibilikiyo ukuze iqhagamshelane ngokulula. Itywinwe kakuhle kwaye ivumela ukuJika ngaphakathi kweedigri ezili-15 ngaphandle kokuvuza.

I-mold yesinyithi esetyenziswayo iyasetyenziswa. Umbhobho wesinyithi otyhidiweyo unobukhulu obufanayo bodonga, ulwakhiwo oluncinci, umphezulu ogudileyo, kwaye akukho ziphene zokuphosa ezifana nama-blister kunye nezinto ezifakwe kwi-slag. I-interface yerabha iyayicima ingxolo kwaye ayinakutshintshwa kwiipayipi ezithuleyo, idala indawo yokuhlala engcono kakhulu.
3. Iindlela ezahlukeneyo zokusetyenziswa
Imibhobho yesinyithi esitshisiweyo ifanelekile ekwakheni imibhobho yamanzi amdaka, ukukhupha amanzi amdaka, ubunjineli bokwakha, imibhobho yokuhambisa amanzi ezindleleni, amanzi amdaka emizi-mveliso, kunye nemibhobho yokunkcenkceshela yezolimo; imibhobho yesinyithi esitshisiweyo ingafaneleka ukwandiswa okukhulu kwe-axial kunye nokufuduka kwe-contraction kunye nokuguqulwa kwe-lateral deflection yemibhobho; imibhobho yesinyithi esitshisiweyo ifanelekile kwiinyikima zomhlaba ezinamandla angama-9 degrees. Sebenzisa kwezi ndawo zilandelayo.

Umbhobho wentsimbi othuthwayo ubizwa ngokuba ngumbhobho wentsimbi othuthwayo ...
