Chitsulo Chochepa cha Mpweya
Chiyambi cha mankhwala:
Njira yopangira ndi yofanana ndi njira yopangira chitsulo cha dziko lonse, pogwiritsa ntchito ukadaulo wa centrifugal granulation, chifukwa zipangizozo ndi zitsulo zochepa za kaboni, choncho musagwiritse ntchito njira yopangira kutentha kwambiri, pogwiritsa ntchito njira yopangira kutentha kwa isothermal.

CHITSULO CHA KHABONI CHOCHEPA
Mtengo wa Ubwino
• Kuchita bwino kuposa 20% poyerekeza ndi kuwombera kwa kaboni wambiri
• Kuchepa kwa kusowa kwa makina ndi zida chifukwa cha kuyamwa kwakukulu kwa mphamvu mu kugunda kwa zidutswazo
• Tinthu tating'onoting'ono topanda zolakwika zomwe zimachitika chifukwa cha kutentha, kusweka kapena ming'alu yaying'ono
KUKONZA CHILENGEDWE
• Kuti ipangidwe, palibe chithandizo china chowonjezera cha kutentha chomwe chikufunika
• Kuchepetsa ufa
• Kapangidwe ka Bainitic kamatsimikizira kuti sikadzasweka nthawi yonse yomwe kadzagwiritsidwe ntchito.
MAONEKEDWE ABWINO
• Kapangidwe ka chitsulo chopanda mpweya wokwanira kamakhala kofanana ndi kozungulira. Kupezeka kochepa kwa tinthu tating'onoting'ono tating'onoting'ono, topindika tokhala ndi ma pores, slag kapena dothi n'kotheka.
• Izi sizikhudza momwe kuwomberako kumagwirira ntchito, zitha kutsimikiziridwa poyesa momwe kumagwirira ntchito pamakina.
KULIMA
• Kapangidwe ka bainitic kamatsimikizira kuuma kwakukulu. 90% ya tinthu tating'onoting'ono timakhala pakati pa 40 - 50 Rockwell C.
• Kuchepa kwa mpweya woipa poyerekeza ndi manganese kumatsimikizira kuti tinthu tating'onoting'ono timakhala ndi moyo wautali, motero timawonjezera kuyera kwa tinthuto, chifukwa tikagwira ntchito ndi makina timawonjezera kuuma kwawo.
• Mphamvu ya kuphulika kwa mfuti imatengedwa makamaka ndi ziwalo, motero imachepetsa kuwonongeka kwa makina.
KUGWIRITSA NTCHITO KWA KHABONI, KUGWIRA NTCHITO KWAMBIRI
• Kugwiritsa ntchito chitsulo chotsika mpweya kuli ndi mwayi wogwiritsa ntchito makina omwe ali ndi ma turbine a 2500 mpaka 3000 RPM komanso liwiro la 80 M / S.
• Pa zipangizo zatsopano zomwe zimagwiritsa ntchito ma turbine a 3600 RPM ndi liwiro la 110 M / S, izi ndi zofunikira kuti pakhale zokolola zambiri.
minda ntchito:
1. Kumaliza pamwamba pa aluminiyamu zinc die casting ndi kuyeretsa pamwamba pa aluminiyamu mchenga casting. Kupopera ndi kupukuta pamwamba pa marble wochita kupanga. Kuyeretsa ndi kumaliza pamwamba pa oxide oxide scale, aluminiyamu alloy engine block ndi zida zina zazikulu casting, chithandizo cha marble surface effect ndi chithandizo choletsa kutsetsereka.
2. Kuyenga zinki ya aluminiyamu, kuyeretsa pamwamba pa kuyika kolondola, kukanda pamwamba musanaphike mwapadera, kupukuta bwino kwa mbiri ya aluminiyamu kuti muchotse mizere yotulutsira pamwamba, kupukuta bwino kwa pamwamba pa chitoliro cha aluminiyamu yamkuwa, ndi kupukuta bwino kwa chidebe chachitsulo chosapanga dzimbiri ndi valavu.
3. Tsukani zida zoponyera zozizira, onjezerani ma chrome plating dies a forging dies ndi matayala, konzani chivundikiro cha pampu cha supercharger ya injini ya galimoto, limbitsani giya yolondola ndi kasupe wa choyambira, ndikupopera pamwamba pa chidebe chachitsulo chosapanga dzimbiri.
4. Choyeretsera zitsulo zopangidwa ndi aluminiyamu, bokosi la injini ya njinga yamoto, mutu wa silinda, kabureta, chipolopolo cha pampu yamafuta a injini, chitoliro cholowera, loko yagalimoto. Pamwamba pa mawonekedwe a mawilo oyeretsera zitsulo zopangidwa ndi mphamvu yochepa payenera kutsukidwa ndi kumalizidwa musanapake utoto. Kumaliza ndi kuyeretsa pamwamba pa zigawo zoyeretsera zitsulo zopangidwa ndi aluminiyamu zopangidwa ndi mkuwa, kuyika zitsulo zopangidwa ndi ndalama, ndi zina zotero.
