Zida zonyamula zomwe zimagwiritsidwa ntchito pamapampu a centrifugal zimagawidwa m'magulu awiri: zida zachitsulo ndi zopanda zitsulo.

Metallic Material

Zipangizo zachitsulo zomwe zimagwiritsidwa ntchito nthawi zambiri pazitsulo zotsetsereka zimaphatikizapo ma alloys okhala (omwe amadziwikanso kuti Babbitt alloys kapena white alloys), chitsulo chosamva kuvala, ma alloys a mkuwa ndi aluminiyamu.

1. Kunyamula Aloyi

Zigawo zazikulu za alloy zokhala ndi ma alloys (omwe amadziwikanso kuti Babbitt alloys kapena white alloys) ndi malata, lead, antimoni, mkuwa, antimoni, ndi mkuwa, zomwe zimagwiritsidwa ntchito kupititsa patsogolo mphamvu ndi kuuma kwa alloy. Zambiri mwazinthu zokhala ndi aloyi zimakhala ndi malo otsika osungunuka, choncho ndi oyenera kugwira ntchito pansi pa 150 ° C.

2. Aloyi yochokera mkuwa

Ma alloys okhala ndi Copper amakhala ndi matenthedwe apamwamba kwambiri komanso kukana kuvala bwino kuposa chitsulo. Ndipo alloy-based alloy ali ndi machinability abwino ndi mafuta, ndipo khoma lake lamkati likhoza kutha, ndipo limagwirizana ndi malo osalala a shaft. 

Zopanda zitsulo

1. PTFE

Ali ndi zinthu zabwino zodzipangira okha mafuta komanso kukhazikika kwamafuta ambiri. Kugundana kwake kumakhala kochepa, sikumamwa madzi, sikumata, sikuyaka, ndipo kungagwiritsidwe ntchito pansi pa -180 ~ 250 ° C. Koma palinso zovuta monga kukula kwa mzere wokulirapo, kusakhazikika bwino, komanso kusayenda bwino kwamafuta. Pofuna kupititsa patsogolo ntchito yake, imatha kudzazidwa ndi kulimbikitsidwa ndi tinthu tating'onoting'ono tachitsulo, ulusi, graphite ndi zinthu zopanda organic.

2. Graphite

Ndi chinthu chabwino chodzipangira mafuta, ndipo chifukwa ndi chosavuta kuchikonza, ndipo chikakhala pansi, chimakhala chosalala, choncho ndi chinthu chosankhidwa pazitsulo. Komabe, mawonekedwe ake amakina ndi otsika, ndipo kukana kwake komanso kunyamula katundu kumakhala kocheperako, motero ndikoyenera nthawi zopepuka. Pofuna kukonza makina ake, zitsulo zina za fusible zokhala ndi kukana kovala bwino nthawi zambiri zimayikidwa. Zida zomwe zimagwiritsidwa ntchito kwambiri ndi Babbitt alloy, copper alloy ndi antimony alloy. 

3. Mpira

Ndi polima yopangidwa ndi elastomer, yomwe imakhala yabwino komanso imayamwa modzidzimutsa. Komabe, matenthedwe ake amatenthedwa bwino, kukonza kumakhala kovuta, kutentha kovomerezeka kumakhala pansi pa 65 ° C, ndipo kumafunikira madzi ozungulira kuti azipaka mafuta ndi kuziziritsa mosalekeza, choncho sagwiritsidwa ntchito kawirikawiri.

4. Carbide

Ili ndi mndandanda wazinthu zabwino kwambiri monga kuuma kwakukulu, kukana kuvala, mphamvu zabwino ndi kulimba, kukana kutentha, komanso kukana dzimbiri. Chifukwa chake, ma fani otsetsereka omwe amakonzedwa nawo amakhala olondola kwambiri, okhazikika, olimba kwambiri, olimba komanso olimba, koma ndi okwera mtengo.

5. SiC

Ndi mtundu watsopano wa zinthu zopangira zinthu zopanda zitsulo. Kuuma kwake ndi kocheperapo poyerekeza ndi diamondi. Ili ndi kukana kwa dzimbiri kwamankhwala, kukana kuvala, kukana kutentha kwambiri, mphamvu zamakina apamwamba, kudzipaka mafuta bwino, kukana kutentha kwapang'onopang'ono, kugunda kwapang'onopang'ono, kutsika kwamafuta, komanso kuchuluka kwamafuta ochepa. Amagwiritsidwa ntchito kwambiri Kugwiritsidwa ntchito mu mafuta, zitsulo, makampani opanga mankhwala, makina, zakuthambo ndi mphamvu za nyukiliya ndi madera ena, nthawi zambiri amagwiritsidwa ntchito ngati mikangano iwiri yazitsulo zotsetsereka ndi zisindikizo zamakina.
