kurasika kukanda wakisi kwave kushanduka kuita nzira yakakurumbira

Pakutanga yakashandiswa muzvishongo,kurasika kukanda wakisi kwave kushanduka kuita nzira yakakurumbira yekugadzira mativi esimbi chaiwo.Zvichienzaniswa nedzimwe nzira dzekugadzira, inokurumidza, inoda vashandi vashoma, inoshandisa michina inodhura zvishoma, uye inobvumira kugadzirwa kwakaoma.Maitiro acho anobatsirawo mukudzikisa huwandu hwezvinhu zvinoraswa zvinopinda mumarara.Kune akawanda mashandisirwo eiyo maitiro, senge muindasitiri yemotokari, indasitiri yendege, uye indasitiri yemakemikari.Muindasitiri yeoiri, semuenzaniso, zvikamu zvinoda kusaita ngurauye kugona kutsungirira tembiricha yakanyanyisa.Muindasitiri yemakemikari, inofanirwa kushingirira kune ngura, kukukurwa kwevhu, uye kumanikidza mamiriro.Pamusoro pekuda hunhu chaihwo, zvikamu zvinodawo kugadzirwa nehungwaru hunoshamisa.Investment casting ndiyo mhinduro inoshanda kune aya matambudziko.Inogonesa vagadziri kuburitsa zvinhu zvakaomarara muzvikamu zvidiki, uku ichidzivirira kudiwa kwemashure-kugadzirisa.Chigadzirwa chakapedzwa chakagadzirira kutumira.Mukukanda wakisi yakarasika,wakisi patani inonyikwa mudhaka remarara.Ceramic slurry inopfekedza patani yewakisi kuita goko rekunze rakaomarara.Simbi yakanyungudutswa inobva yawedzerwa kugoko receramic rakaomeswa.Rutivi rwekunze rwunobva rwaiswa kumhepo.Kuongorora kwekupedzisira kwezvinhu kunoitwa.Mushonga wepamusoro unoshandiswawo.Izvi zvinogona kuwedzera kutaridzika kwepamusoro pesimbi.Mienzaniso yekutanga yakarasika yekukanda wakisi inodzokera ku3700 BC.Mimwe mienzaniso yezvakarasika zvekukanda wakisi zvakawanikwa muIsrael, Vietnam, Africa, uye Indus Valley.Mamwe akawanikwa muEurope, East Asia, uye Nigeria.Iyo nzira yakashandiswa kugadzira zvinhu zveunyanzvi, zvivezwa, uye zvishongo kwezviuru zvemakore.Muzana ramakore rechi 18, nzira iyi yakatsiviwa nechidimbu-kuumba.Nekudaro, kurasika wakisi kukanda kunoramba kuchishandiswa zvakanyanya muindasitiri yezvishongo.Kureruka kwayo kunoita kuti ive sarudzo yakakodzera yezvishongo zvetsika.Iyo yakarasika yekukanda wax process inoshandisa akasiyana simbi,zvakadai sebhuronzi, aluminium, uye simbi isina tsvina.Simbi yekukandira iaruminiyamu nekuti inogoneka uye isingadziviriri ngura.Inopawo yakanakisa simbi-ku-metal lubrication.Mamwe masimbi, akadai semhangura, anogona kushandiswa pakukanda.Iyo nzira inoshandiswa kukanda huwandu hwakawanda hwezvikamu, kubva padiki,zvikamu zvakapfava kune zvimedu zvakakura, zvinorema.Iyo inonyanya kukodzera kune simbi ine yakaderera kunyungudika.Iyo inozivikanwa zvakare kuti inobatsira muindasitiri yezvekudya uye zvinwiwa, uko zvigadzirwa zvakagadzirirwa kumirisana nemakemikari ane acid kubva mukudya.Muindasitiri yemotokari, zvikamu zvinogadzirwa kubva kune ese ari maviri ferrous uye asiri-ferrous simbi.Zvikamu zvakagadzirirwa kuti zvive zvakachengeteka uye zvinoshanda.Iwo maindasitiri ekusimudza anoshandiswa akatwasuka uye akatwasuka, uye anofanira kunge akasimba.Vanotarisanawo nemamiriro okunze akaoma uye kupisa kwakanyanya.Indasitiri yemakemikari ine dambudziko rakawanda rekuora uye kukukurwa kwevhu, saka zvikamu zvinofanirwa kushingirira kumamiriro ekunze.Indasitiri yemotokari inoshandisa yakarasika kukanda wakisi kune ayo einjini zvikamu, gearbox zvikamu, uye compressor zvikamu.
