Ng'anjo zamtundu wa Bell

Chidule:
Ng'anjo zamtundu wa Bell zimagwiritsidwa ntchito popanga chowala chowala ndi kutentha, chifukwa chake ndizowotcha mosiyanasiyana mosiyanasiyana. Kutentha kumakhala pakati pa 650 ndi 1100 ℃ makamaka, ndipo kumasintha nthawi yomwe yatchulidwa pakuwotcha. Kutengera kutsitsa kwa ng'anjo yamtundu wa belu, pali mitundu iwiri: ng'anjo yamiyala yaying'ono yam'mbali ndi yoyatsa yozungulira ngati belu. Kutentha kwa ng'anjo yamtundu wa belu makamaka ndi mpweya, kutsatiridwa ndi magetsi ndi mafuta owala. Nthawi zambiri, ziwaya zamtundu wa belu zimakhala ndimagawo atatu: chivundikiro chakunja, chikuto chamkati, ndi chitofu. Chipangizocho chimayikidwa pachikuto chakunja chazotenthedwa, pomwe magwiridwe antchito amayikidwa pachikuto chamkati cha kutentha ndi kuzizira.

Ng'anjo zamtundu wa Bell zimakhala ndi mpweya wabwino, kutentha pang'ono, komanso kutentha kwambiri. Kuphatikiza apo, safunanso chitseko cha ng'anjo kapena makina okwezera ndi njira zina zamagetsi zotumizira, motero zimasunga ndalama ndipo zimagwiritsidwa ntchito kwambiri pamaofesi otentha.
Zofunikira ziwiri zofunika kwambiri pazitsulo zopangira ng'anjo ndizolemera pang'ono komanso mphamvu zamagetsi zotsekera.

Zovuta zomwe zimachitika ndi refracto yachikhalidwe yopepukanjerwa kapena zopepuka zosunthika stZowonongeka zikuphatikiza:

1. Zipangizo zojambulidwa ndi mphamvu yokoka yayikulu (makamaka njerwa zopepuka zopepuka zimakhala ndi kukula kwa 600KG / m3 kapena kupitilira apo; chopepuka chopepuka chili ndi 1000 KG / m3 kapena kupitilira apo) chimafuna katundu wambiri pachitsulo chachitsulo cha uvuni, kugwiritsidwa ntchito kwa kapangidwe kazitsulo komanso ndalama pakuwonjezeka kwa ng'anjo.

2. Chophimba chachikulu chakunja chimakhudza mphamvu yokweza komanso malo apansi pamisonkhano yopangira.

3. Ng'anjo yamtundu wa belu imagwiritsidwa ntchito pakatenthedwe kosiyanasiyana, ndipo njerwa zopepuka zoyatsira kapena zotayira zopepuka zimakhala ndi kutentha kwakukulu, kutentha kwambiri, komanso kugwiritsa ntchito mphamvu zambiri.

Komabe, zida zopangira ma CCEWOOL zimakhala ndi matenthedwe ochepa, kutentha pang'ono, komanso kutsika kwa voliyumu, zomwe ndi zifukwa zazikulu zogwiritsira ntchito zokutira. Makhalidwewa ndi awa:

1. Kutentha kwakukulu kogwira ntchito ndi mitundu yosiyanasiyana yofunsira
Ndi chitukuko cha CCEWOOL ceramic fiber yopanga ndi ukadaulo, CCEWOOL zopangira za ceramic fiber zakwaniritsa serialization ndi functionalization. Kumbali ya kutentha, malonda amatha kukwaniritsa zofunikira za kutentha kosiyanasiyana kuyambira 600 mpaka 1500 ℃. Kumbali ya kafukufuku wakapangidwe kazachilengedwe, zopangidwazo pang'onopang'ono zakhala zikugwiritsidwa ntchito mosiyanasiyana kuchokera ku thonje zachikhalidwe, zofunda, zopangidwa ndi ma module a fiber, matabwa, mbali zopangidwa mwapadera, mapepala, nsalu za fiber ndi zina zambiri. Amatha kukwaniritsa zofunikira zonse zazitsulo zamagetsi zopangira zida za ceramic m'makampani osiyanasiyana.
2. Kuchuluka kwazing'ono:
Kuchuluka kwa voliyumu yazinthu zopangira ceramic nthawi zambiri kumakhala 96 ~ 160kg / m3, yomwe ili pafupifupi 1/3 ya njerwa zopepuka ndi 1/5 yazitsulo zopepuka zopepuka. Pa ng'anjo yomwe yangopangidwa kumene, kugwiritsa ntchito zida za ceramic fiber sikungangopulumutsa zitsulo zokha, komanso kupangira kutsitsa / kutsitsa ndi mayendedwe mosavuta, ndikupititsa patsogolo ukadaulo waukadaulo wamafuta.
3. Kutentha kwakung'ono ndikusungira kutentha:
Poyerekeza ndi njerwa zaumboni ndi njerwa zotchingira, mphamvu yazinthu zopangira ceramic ndizotsika kwambiri, pafupifupi 1 / 14-1 / 13 ya njerwa zopangira ndi 1 / 7-1 / 6 njerwa zotchingira. Pogwiritsa ntchito ng'anjo yamtundu wa belu, mafuta ambiri osagwiritsa ntchito mafuta amatha kupulumutsidwa.
4. Ntchito yomanga yosavuta, nthawi yayifupi
Monga mabulangete a ceramic ndi ma module okhala ndi zotanuka zabwino kwambiri, kuchuluka kwa kupanikizika kumatha kunenedweratu, ndipo palibe chifukwa chosiya malo olumikizirana pakumanga. Zotsatira zake, ntchito yomanga ndiyosavuta komanso yosavuta, yomwe imatha kumaliza ntchito ndi akatswiri aluso.
5. Ntchito popanda uvuni
Pogwiritsira ntchito zowonjezera zowonjezera, ng'anjo imatha kutenthedwa kutentha kutentha ngati sikuletsedwa ndi zitsulo zina, zomwe zimapangitsa kuti magwiritsidwe ntchito a mafakitale azigwiritsa ntchito bwino komanso amachepetsa mafuta osagwiritsidwa ntchito.
6. Kutsika kotsika kwambiri kwamatenthedwe
Ceramic CHIKWANGWANI ndi kuphatikiza ulusi ndi awiri a 3-5um, motero ali otsika kwambiri matenthedwe madutsidwe. Mwachitsanzo, bulangeti ya aluminiyamu yayikulu yokhala ndi kuchuluka kwa 128kg / m3 ikafika 1000 ℃ pamalo otentha, koyefitenti yake yotulutsa kutentha ndi 0.22 yokha (W / MK).
7.Bwino mankhwala bata ndi kukana mpweya kukokoloka:
Ceramic fiber imatha kusokonekera mu asidi ya phosphoric, hydrofluoric acid, ndi soda yotentha, ndipo imakhazikika kuzinthu zina zowononga. Kuphatikiza apo, ma ceramic fiber module amapangidwa ndi kupindika mosalekeza mabulangeti a ceramic fiber pamlingo wina wothinirana. Pambuyo pothandizidwa pamwamba, kukokoloka kwa mphepo kumatha kufika 30m / s.
