Copper bushing centrifugal kuponyera

Ukadaulo wa centrifugal kuponyera ma bushings amkuwa ndi njira yabwino komanso yolondola yoponyera, yomwe imagwiritsidwa ntchito kwambiri popanga zitsulo zamkuwa zomwe zimagwiritsidwa ntchito pazida zamakina, magalimoto, migodi ndi makina ena olemera. Mfundo yaikulu ya kuponyera kwa centrifugal ndikugwiritsa ntchito mphamvu ya centrifugal yomwe imapangidwa ndi nkhungu yothamanga kwambiri kuti igawitse madzi achitsulo ku khoma lamkati la nkhungu, potero kupanga kachulukidwe kakang'ono komanso kochita bwino.

Basic mfundo ya centrifugal kuponyera luso

Kuponyera kwa Centrifugal ndikutsanulira madzi osungunuka achitsulo mu nkhungu yozungulira, kukankhira madzi achitsulo ku khoma la nkhungu ndi mphamvu ya centrifugal, ndipo potsiriza kupanga kuponya kolimba. Panthawi yoponyera, chifukwa cha mphamvu ya centrifugal, kuchuluka kwa zigawo zamkati ndi zakunja za kuponyera kumasiyana. Chosanjikiza chakunja chimakhala pafupi ndi khoma la nkhungu, lomwe nthawi zambiri limapanga mawonekedwe ophatikizika komanso owundana, ndipo gawo lamkati limakhala lotayirira, lomwe ndi loyenera kupanga castings ndi zinthu zapadera zakuthupi.

Centrifugal kuponyera ndondomeko yamkuwa bushings

Zitsamba zamkuwa nthawi zambiri zimapangidwa ndi aloyi amkuwa. The centrifugal casting process makamaka imaphatikizapo izi:

1. Kukonzekera kwa nkhungu Nthawi zambiri nkhungu imapangidwa ndi zida zamphamvu zotsutsa, zomwe zimatha kupirira kutentha kwambiri ndikukhalabe okhazikika panthawi yozungulira. Khoma lamkati la nkhungu likhoza kupangidwa mwa mawonekedwe a bushing.

2. Kusungunuka kwa chitsulo Chosakaniza chamkuwa chimatenthedwa kuti chisungunuke, nthawi zambiri mu ng'anjo yotentha kwambiri, ndipo kutentha kosungunuka kumakhala pakati pa 1050 ° C ndi 1150 ° C.

3. Thirani chitsulo chosungunuka Chitsulo chosungunuka chimatsanuliridwa mu nkhungu yozungulira kupyolera mu dziwe losungunuka. Kuthamanga kozungulira kwa nkhungu nthawi zambiri kumayendetsedwa pa khumi mpaka mazana osinthika pamphindi, ndipo liwiro lozungulira limakhudza mwachindunji khalidwe ndi mapangidwe a kuponyera.

4. Kuzizira ndi kulimba Chitsulo chosungunuka chimalimba mu nkhungu chifukwa cha kuzizira. Chifukwa cha mphamvu ya centrifugal, chitsulo chosungunula chimagawidwa mofanana, kupanga khoma lakunja lapamwamba, pamene khoma lamkati limakhala lotayirira.

5. Kuwotcha ndi kuyang'anitsitsa Pambuyo poponyedwa utakhazikika, nkhungu imasiya kusinthasintha, kugwetsa ndi kufufuza koyenera kumachitidwa kuti zitsimikizire kuti tchire lamkuwa limakwaniritsa kukula ndi zofunikira.

Ubwino wa centrifugal kuponyera mkuwa bushings

Kuchulukana kwakukulu komanso mphamvu yayikulu: Kuponyera kwa Centrifugal kumatha kupanga wosanjikiza wakunja wa kuponyedwa kowuma kudzera mu mphamvu ya centrifugal, ndipo kumakhala ndi zida zamakina apamwamba.

1. Zowonongeka zochepa za kuponyera: Kuponyera kwa centrifugal kumachepetsa kubadwa kwa zolakwika monga pores ndi inclusions, ndikuwongolera khalidwe la castings.

2. Kukana kuvala bwino: Zitsamba zamkuwa zamkuwa nthawi zambiri zimagwiritsidwa ntchito kupirira mikangano yayikulu. Ukadaulo wakuponya wa Centrifugal umapangitsa kuuma kwa pamwamba kwa ma castings apamwamba komanso kukana kuvala kumakhala bwino.

3. Kukonzekera kwapamwamba kwambiri: Zitsamba zamkuwa za centrifugally zimatha kulamulira molondola kukula ndi mawonekedwe, kuchepetsa ntchito yokonza pambuyo pake.

Zogwiritsidwa ntchito

Zida za Copper alloy zomwe zimagwiritsidwa ntchito popanga centrifugal ndi:

Kuponya mkuwa (monga copper-tin alloy, copper-lead alloy)

Mkuwa (monga bronze, aluminium bronze)

Mkuwa wa aluminiyamu, zotayirazi zimakhala ndi kukana kwa dzimbiri komanso kukana kuvala, zoyenera kugwiritsidwa ntchito ngati zida zamatabwa.

Magawo ofunsira

Ukadaulo woponyera ma centrifugal wamkuwa umagwiritsidwa ntchito popanga ma bushings apamwamba kwambiri, zonyamula, zowongolera ndi mbali zina, ndipo zimagwiritsidwa ntchito kwambiri mu:

Zipangizo zamakina: monga kunyamula tchire muzipangizo zamakina zopatsirana.

Makampani opanga magalimoto: Zomera zomwe zimagwiritsidwa ntchito ngati injini zamagalimoto, ma gearbox ndi magawo ena.

Zida zamigodi: Zogwiritsidwa ntchito pazinthu zomwe zimafuna kukana kuvala kwambiri pamakina akumigodi.

Chikoka cha magawo ndondomeko

Liwiro lozungulira: Liwiro lozungulira limatsimikizira kufanana kwa kugawa kwamadzimadzi achitsulo ndi kuchuluka kwa kuponyera. Kukwera kwambiri kapena kutsika kwambiri kungakhudze khalidwe la kuponya.

Kutentha kwamadzi achitsulo: Kutsika kwamadzimadzi kwachitsulo kungayambitse kuchepa kwa madzi, pamene kutentha kwambiri kungayambitse makutidwe ndi okosijeni mosavuta ndi mavuto ena.

Liwiro lozizira: Kuthamanga kozizira kumakhudza mawonekedwe a microstructure. Kuthamanga kwambiri kapena pang'onopang'ono kungakhudze kachitidwe ka copper bushing.

Mwachidule, ukadaulo wa centrifugal kuponyera zamkuwa ndi njira yabwino kwambiri yopanga. Ikhoza kutulutsa zitsamba zamkuwa zokhala ndi zida zabwino zamakina, zolondola kwambiri komanso zosalala. Ndi njira yabwino yopangira zida zambiri zamakina apamwamba kwambiri.
