Kusiyana Kwakukulu Pakati pa Silicon Carbide ndi Tungsten Carbide Mechanical Seals
Kuyerekeza kwa Zinthu Zakuthupi ndi Zamankhwala
Silicon Carbide, pawiri iyi imakhala ndi mawonekedwe a crystalline opangidwa ndi silicon ndi maatomu a kaboni. Imakhala ndi matenthedwe osayerekezeka pakati pa zida zamaso osindikizira, kuuma kwakukulu komwe kudavotera 9.5 pa sikelo ya Mohs - yachiwiri kwa diamondi - kuphatikiza katundu wabwino kwambiri wokana dzimbiri. SiC ilinso ndi zinthu zopanda oxide ceramic zomwe zimabweretsa kulimba kwambiri chifukwa cha zomangira zake zodalirika zomwe zimakula molunjika pazinthu zonse.
Tungsten Carbide ndi aloyi wopangidwa makamaka ndi zinthu za Tungsten ndi Carbon. Zimapangidwa kudzera mu njira yotchedwa sintering yomwe imapangitsa kuti zinthu zikhale zovuta kwambiri pakati pa 8.5-9 pa sikelo ya Mohs - yolimba mokwanira kuti igwiritsidwe ntchito koma osati molimba ngati SiC. Kuphatikiza pa kukhala wandiweyani, WC imawonetsa kukhazikika kodabwitsa kozungulira kutentha; komabe, ndizokhazikika pamankhwala poyerekeza ndi Silicon Carbide.
Kusiyanasiyana kwa Kachitidwe Pansi Pazinthu Zosiyanasiyana Zogwirira Ntchito
Poyerekeza magwiridwe antchito a silicon carbide (SiC) ndi tungsten carbide (WC) zosindikizira zamakina pansi pazigawo zosiyanasiyana zogwirira ntchito, ndikofunikira kukambirana momwe amayankhira pazinthu monga kutentha kwambiri, kusiyanasiyana kwamakasitomala, media zowononga, komanso kuthekera kwawo kuthana ndi zovuta.
Pankhani ya kukana kutentha, silicon carbide imawonetsa matenthedwe abwino kwambiri ndipo imatha kugwira ntchito bwino pamatenthedwe apamwamba poyerekeza ndi tungsten carbide. Chikhalidwe ichi chimapangitsa SiC kukhala chisankho choyenera kwa mapulogalamu omwe kupirira kutentha kumakhala kofunikira.
M'malo mwake, poganizira kukana kukakamiza, tungsten carbide imakhala ndi mwayi wapadera kuposa silicon carbide. Kapangidwe kake kocheperako kamathandizira kupirira kupsinjika kwambiri kuposa SiC. Chifukwa chake, zisindikizo za WC ndizoyenera kugwiritsa ntchito zolemetsa zokhala ndi zovuta zambiri.
Kutengera ndi zida zogwirira ntchito zomwe zisindikizozi zimawululidwa, kukana kwa dzimbiri kumakhala gawo lina lofunikira pakuwunika. Silicon carbide imaposa tungsten carbide pokana njira za acidic ndi alkaline chifukwa cha kusakhala kwake ndi mankhwala. Chifukwa chake, zisindikizo za SiC zimakondedwa m'mafakitale omwe akukumana ndi madzi aukali kapena mpweya.
Kukana kuvala pakati pa mitundu iwiriyi ya zisindikizo kumabwereranso m'malo mwa tungsten carbide chifukwa cha kuuma kwake kwachibadwa, kumapangitsa kuti ikhale yokonzeka kuthana ndi zovuta zomwe zimagwiritsidwa ntchito nthawi yayitali.
Kuyerekeza Mtengo
Nthawi zambiri, mtengo woyamba wa zisindikizo za tungsten carbide ukhoza kukhala wokwera kuposa zofananira za silicon carbide chifukwa chakusamva bwino komanso kuuma kwake. Komabe, ndikofunikira kuti musamangoganizira za ndalama zam'mbuyomu, komanso zowononga nthawi yayitali.
Ngakhale zisindikizo za tungsten carbide zingafunike ndalama zokulirapo zoyambira, moyo wawo wautali komanso magwiridwe antchito amatha kuthana ndi ndalama zoyambira izi pakapita nthawi. Kumbali ina, zisindikizo za silicon carbide nthawi zambiri zimakhala zotsika mtengo zam'tsogolo zomwe zimawapangitsa kukhala njira yabwino yamabizinesi omwe amaganizira za bajeti. Komabe, potengera kutsika kwawo kocheperako muzochitika zina, angafunike kusinthidwa pafupipafupi kapena kukonza zomwe zimapangitsa kuti pakhale ndalama zambiri zanthawi yayitali.
Kusiyana kwa Durability ndi Wear Resistance
Zisindikizo zamakina a Silicon Carbide zimakhala ndi kuuma kwapadera kophatikizana ndi matenthedwe apamwamba. Kuphatikizana kumeneku kumapangitsa kuti asatengeke kuvala chifukwa cha kukangana, kuchepetsa mwayi wawo wopunduka ngakhale pansi pa ntchito zovuta. Komanso, resistivity awo motsutsana ndi dzimbiri mankhwala kumawonjezera kulimba kwawo konse.
Kumbali ina, zisindikizo zamakina a Tungsten Carbide zimapereka mphamvu zosayerekezeka komanso zolimba, zomwe zimawathandiza kupirira kupsinjika kwakuthupi kwakanthawi. Kulimba kwawo kumapangitsa kuti azigwira ntchito mosasinthasintha ngakhale atakumana ndi zovuta, zomwe zimakweza kukana kwawo kuvala kwambiri.
Zida zonsezi zimalimbana ndi kufalikira kwa kutentha; Komabe, Silicon Carbide imawonetsa kukana kwamphamvu kwamafuta pang'ono poyerekeza ndi Tungsten Carbide. Izi zikutanthauza kuti zisindikizo za SiC sizikhoza kung'ambika kapena kuwonongeka pamene zimasintha mofulumira kutentha-chinthu chomwe chimathandizira kuti chikhale cholimba.
Momwe Mungasankhire Pakati pa Silicon Carbide ndi Tungsten Carbide Mechanical Zisindikizo
Choyamba, ndikofunikira kuganizira malo omwe zisindikizo zidzagwira ntchito. Izi zimatengera zinthu monga momwe zimapangidwira, kutentha kwapakati, kupanikizika, komanso kuthekera kwa zinthu zilizonse zowononga. WC imayamikiridwa kwambiri chifukwa cha kulimba kwake komanso kukana kuvala. Chifukwa chake, imatha kuyanjidwa m'malo omwe amafunikira kulimba motsutsana ndi abrasion kapena kupsinjika kwambiri.
Kumbali inayi, SiC imawonetsa kukana kutenthedwa kwa kutentha ndi dzimbiri zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito pomwe kusintha kwakukulu kwa kutentha kumayembekezeredwa kapena madzi owononga kwambiri. Kutsika kwake kothandizana bwino ndi mphamvu kumatanthauzanso kugwiritsa ntchito mphamvu pang'ono motero kupangitsa kuti zisindikizo za SiC zikhale zoyenera kuti zizigwira ntchito movutikira mphamvu.
Kuphatikiza apo, malingaliro azachuma sakuyenera kunyalanyazidwa popanga chisankho; pomwe WC imadzitamandira kuuma kokulirapo komanso kukana kuvala, imakhala yokwera mtengo kuposa ma SiC. Chifukwa chake, ngati kuchepa kwa bajeti ndikulepheretsa, kusankha SiC kungakhale yankho lotheka pokhapokha ngati palibe zovuta / zowononga zogwirira ntchito.
Pomaliza, chofunikira kwambiri ndi kukhulupirika kwa mtundu wanu kapena zomwe munakumana nazo kale ndi silicon carbide mechanical seals kapena tungsten carbide mechanical seals. Mabizinesi ena amapitilira kugwiritsa ntchito kutengera zomwe zidachitika kale kapena zomwe zidachitika m'mbuyomu pogwiritsa ntchito mtundu wina kuposa wina zomwe zimawoneka zomveka kuchokera kudalirika.
Pomaliza
Pomaliza, Silicon Carbide ndi Tungsten Carbide mechanical seals ndi njira ziwiri zosiyana zogwiritsira ntchito makina. Ngakhale Silicon Carbide imapereka kukana kutentha komanso kusasunthika kwamankhwala, Tungsten Carbide imadziwika chifukwa cha kulimba kwake komanso mphamvu zake pansi pamikhalidwe yovuta kwambiri. Kusankha kwanu pakati pa zida ziwirizi kuyenera kutsogozedwa ndi zosowa zanu zenizeni ndi zomwe mukufuna kugwiritsa ntchito; palibe yankho lachilengedwe chonse. Gulu lathu la akatswiri odziwa zambiri ku XYZ Inc. limachita bwino popereka mayankho osinthika kuti agwirizane ndi zosowa zamafakitale zosiyanasiyana mogwira mtima.
Tsopano mwavumbulutsa kusiyana pakati pa Silicon Carbide ndi Tungsten Carbide mechanical seals, koma mwachiwonekere, kumvetsetsa kuti ndi iti yomwe imagwirizana bwino ndi zida zanu zogwirira ntchito ndi ntchito zake zitha kukhala zovuta. Fortune amakonda odziwitsidwa! Chifukwa chake onetsetsani kuti mwadzikonzekeretsa ndi upangiri wogwirizana ndi zomwe makampani anu amafunikira.
