Kazhinji kutaura, dhizaini yemageti masisitimu anotevera misimboti mitatu:
1. Kudira nekukurumidza: kuderedza kudonha kwekushisa, kuderera uye oxidation;
2. Kudira kwakachena: dzivisa chizvarwa che slag uye tsvina, uye dzivirira slag musimbi yakanyungudutswa kubva mugomba;
3. Economic kudurura: kuwedzera maitiro egoho.
1. Nzvimbo yechikamu chekukachidza
1. Paunenge uchigadzira dhizaini yekudurura, chinhu chekutanga kutarisisa inzvimbo yechikamu chekuyerera chinovharira, nekuti inosarudza kukurumidza kuzadza. Kazhinji kutaura, kune nzvimbo mbiri dzechinyakare dzekuronga zvikamu zvekudzipwa.
2.Imwe ndeyekuronga pakati pe lateral mumhanyi uye mumhanyi wemukati. Nhamba yacho inogona kuenderana nenhamba yemumhanyi wemukati. Inonziwo kudira pressure. Sezvo chidimbu chemuchinjiko chiri pedyo nekukandwa, mutsara wekumhanya kwesimbi yakanyungudutswa yakanyanya kana ichipinda mugomba.
3.Imwe inoiswa pakati pe sprue uye lateral runner, ine chikamu chimwe chete chinoyerera-chivharo, chinonziwo pressureless kudurura.
4.Modern cast iron production haiparadzaniswa kubva kune teknolojia yekusefa. Kuti ushandise zvirinani foam ceramic filters, sprue inofanira kushandiswa sechikamu chinovharira kuyerera mukugadzira dhizaini.
Zvinhu zvokufunga nezvazvo
1.Kudurura nguva, iyi ndeimwe yemabasa ekudurura hurongwa, uye kune maitiro akasiyana-siyana. Mazuva ano, simulation software inonyanya kushandiswa kuiverenga. Saka pane nzira inokurumidza kuverenga nemaoko here? Mhinduro: Hongu, uye zviri nyore.
T sec =√(W.lb)
Pakati pazvo: t inguva yekudurura, chikwata masekondi, W ndiyo inorema, iyo unit mapaundi. Zvichengetedze zviri nyore.
2. Friction coefficient. Simbi yakanyungudutswa ichakwesha pamadziro eforoma panguva yekudira. Kukakavadzana kuchaitikawo pakati pesimbi yakanyungudutswa uye pachave nekurasikirwa kwesimba, saka inofanirwa kutariswa.
Kazhinji kutaura, kune dzakatetepa-madziro mahwendefa, iyo friction coefficient § inofanira kunge idiki se0.2; kune dzakakora uye masikweya zvikamu, friction coefficient§inofanira kunge yakakura se0.8.
3.Ehe, iwe unogona zvakare kuve wakanyatsojeka. Chati iri pazasi inogona kushandiswa kuiwana.
