Kusiyana Kwakukulu Pakati pa Silicon Carbide ndi Tungsten Carbide Mechanical Seals
Kuyerekeza kwa Katundu Wathupi ndi Mankhwala
Silicon Carbide, chophatikiza ichi chili ndi kapangidwe ka kristalo kopangidwa ndi maatomu a silicon ndi carbon. Chimakhala ndi kutentha kosayerekezeka pakati pa zinthu zomatira, kuuma kwakukulu komwe kuli pa 9.5 pa sikelo ya Mohs - yachiwiri pambuyo pa diamondi - komanso mphamvu yabwino yolimbana ndi dzimbiri. SiC ndi chinthu cha ceramic chosakhala ndi okosijeni chomwe chimapangitsa kuti chikhale cholimba kwambiri chifukwa cha ma covalent bonds ake odalirika omwe amakula mbali zonse za chinthucho.
Tungsten Carbide ndi alloy yopangidwa makamaka ndi zinthu za Tungsten ndi Carbon. Imapangidwa kudzera mu njira yotchedwa sintering yomwe imapangitsa kuti zinthu zikhale zolimba kwambiri pakati pa 8.5-9 pa sikelo ya Mohs - zolimba mokwanira kuti zigwiritsidwe ntchito koma osati zolimba ngati SiC. Kuwonjezera pa kukhala zokhuthala, WC imakhala ndi kulimba kwakukulu pozungulira kutentha; komabe, siigwira ntchito bwino kwambiri poyerekeza ndi Silicon Carbide.
Kusiyana kwa Magwiridwe Antchito Pansi pa Mikhalidwe Yosiyanasiyana Yogwirira Ntchito
Poyerekeza momwe silicon carbide (SiC) ndi tungsten carbide (WC) zimagwirira ntchito m'malo osiyanasiyana ogwirira ntchito, ndikofunikira kukambirana momwe zimayankhira pazinthu monga kutentha kwambiri, kusinthasintha kwa kuthamanga kwa magazi, zinthu zowononga, komanso kuthekera kwawo kuthana ndi mavuto obwera chifukwa cha kutentha.
Ponena za kukana kutentha, silicon carbide imakhala ndi mphamvu yabwino kwambiri yoyendetsera kutentha ndipo imatha kugwira ntchito bwino kutentha kwambiri poyerekeza ndi tungsten carbide. Khalidweli limapangitsa SiC kukhala chisankho chabwino kwambiri chogwiritsidwa ntchito pomwe kupirira kutentha kwambiri ndikofunikira.
M'malo mwake, poganizira za kukana kupanikizika, tungsten carbide ili ndi ubwino wapadera kuposa silicon carbide. Kapangidwe kake kokhuthala kamathandiza kuti ipirire kupsinjika kwakukulu kuposa SiC. Chifukwa chake, zisindikizo za WC ndizoyenera kwambiri kugwiritsidwa ntchito molimbika kwambiri komanso molimbika kwambiri.
Kutengera ndi malo ogwirira ntchito omwe zisindikizo izi zimaonekera, kukana kuwononga kumakhala chinthu china chofunikira kwambiri pakuwunika. Silicon carbide imagwira ntchito bwino kuposa tungsten carbide polimbana ndi acidic ndi alkaline chifukwa cha kusagwira ntchito kwa mankhwala. Chifukwa chake, zisindikizo za SiC zimakondedwa m'mafakitale omwe amagwira ntchito ndi madzi kapena mpweya woopsa.
Kukana kwa mitundu iwiriyi ya zisindikizo kumabwerera m'malo mwa tungsten carbide chifukwa cha kuuma kwake kwachibadwa, zomwe zimapangitsa kuti ikhale yokonzeka bwino kuthana ndi mavuto okhwima pakapita nthawi yayitali.
Kuyerekeza Mtengo
Kawirikawiri, mtengo woyambirira wa tungsten carbide seals ukhoza kukhala wokwera kuposa wa silicon carbide equivalents chifukwa cha kukana kwake kuwonongeka komanso kuuma kwake. Komabe, ndikofunikira kuganizira osati ndalama zokha zoyambira, komanso ndalama zogwirira ntchito kwa nthawi yayitali.
Ngakhale kuti ma seal a tungsten carbide angafunike ndalama zambiri poyamba, kukhala kwawo nthawi yayitali komanso kugwira ntchito bwino kungathandize kuchepetsa ndalama zomwe zimafunika poyamba pakapita nthawi. Kumbali ina, ma seal a silicon carbide nthawi zambiri amakhala otsika mtengo kwambiri zomwe zimapangitsa kuti akhale njira yabwino kwa mabizinesi omwe amasamala za bajeti. Komabe, chifukwa cha kukana kwawo kutopa pang'ono m'mikhalidwe ina, angafunike kusinthidwa pafupipafupi kapena kukonzedwa zomwe zimapangitsa kuti ndalama zambiri zikwere.
Kusiyana kwa Kulimba ndi Kukana Kuvala
Zisindikizo zamakina za Silicon Carbide zimakhala ndi kuuma kwapadera komanso kutentha kwambiri. Kuphatikiza kumeneku kumapangitsa kuti zisawonongeke chifukwa cha kukangana, zomwe zimachepetsa mwayi wawo wosinthika ngakhale atakhala pantchito yovuta kwambiri. Kuphatikiza apo, kukana kwawo ku dzimbiri la mankhwala kumawonjezera kulimba kwawo konse.
Kumbali inayi, zisindikizo za makina a Tungsten Carbide zimapereka mphamvu komanso kulimba kosayerekezeka, zomwe zimawathandiza kupirira kupsinjika kwakukulu kwa thupi kwa nthawi yayitali. Kulimba kwawo kumatsimikizira kuti amagwira ntchito bwino ngakhale atakhala ndi zovuta, zomwe zimapangitsa kuti asamawonongeke kwambiri.
Zipangizo zonsezi zimalimbana ndi kutentha kwambiri; komabe, Silicon Carbide imakhala ndi mphamvu yolimbana ndi kutentha kwambiri poyerekeza ndi Tungsten Carbide. Izi zikutanthauza kuti ma SiC seal sangasweke kapena kusokonekera kwambiri akakumana ndi kusintha kwa kutentha mwachangu—chinthu chomwe chimathandiza kwambiri pankhani yolimba.
Momwe Mungasankhire Pakati pa Silicon Carbide ndi Tungsten Carbide Mechanical Seals
Choyamba, ndikofunikira kuganizira za malo omwe zisindikizo zidzagwire ntchito. Izi zimaganizira zinthu monga mtundu wa madzi omwe amapangidwa, kutentha komwe kumasiyana, kuchuluka kwa kupanikizika, komanso kuthekera kwa zinthu zina zowononga. WC imalemekezedwa kwambiri chifukwa cha kulimba kwake komanso kukana kuvala. Chifukwa chake, ikhoza kukondedwa m'malo omwe amafuna kulimba motsutsana ndi kukwawa kapena kupsinjika kwakukulu.
Kumbali inayi, SiC imalimbana bwino ndi kutentha ndi dzimbiri zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito komwe kutentha kukuyembekezeka kusintha kwambiri kapena madzi owononga kwambiri amapezeka. Mphamvu zake zochepa zogwirira ntchito pamodzi zimatanthauzanso kuti kugwiritsa ntchito mphamvu zochepa kumapangitsa kuti zisindikizo za SiC zikhale zoyenera kugwiritsidwa ntchito polimbana ndi mphamvu.
Kuphatikiza apo, nkhani zachuma siziyenera kunyalanyazidwa popanga chisankho ichi; ngakhale kuti WC ili ndi kuuma kwapamwamba komanso mphamvu zopewera kukalamba, nthawi zambiri imakhala yokwera mtengo kuposa SiC. Chifukwa chake, ngati zoletsa bajeti ndi chinthu choletsa, kusankha SiC kungakhale yankho lothandiza pokhapokha ngati palibe zovuta/zowononga ntchito.
Chomaliza komanso chofunika kwambiri ndi kukhulupirika kwanu ku kampani kapena zomwe mudakumana nazo kale ndi zisindikizo zamakina za silicon carbide kapena zisindikizo zamakina za tungsten carbide. Mabizinesi ena amapitiliza kugwiritsa ntchito kutengera mbiri yakale kapena momwe adagwirira ntchito kale pogwiritsa ntchito mtundu wina kuposa wina zomwe zikuwoneka zomveka kuchokera pamalingaliro odalirika.
Pomaliza
Pomaliza, zisindikizo za makina a Silicon Carbide ndi Tungsten Carbide ndi njira ziwiri zosiyana zogwiritsira ntchito makina. Ngakhale Silicon Carbide imapereka kukana kutentha komanso kukhazikika kwa mankhwala, Tungsten Carbide imadziwika chifukwa cha kulimba kwake komanso mphamvu zake pamikhalidwe yovuta kwambiri. Kusankha kwanu pakati pa zipangizo ziwirizi kuyenera kutsogozedwa ndi zosowa zanu komanso zofunikira pakugwiritsa ntchito; palibe yankho lapadziko lonse. Gulu lathu la akatswiri odziwa bwino ntchito ku XYZ Inc. limachita bwino popereka njira zothetsera mavuto kuti zigwirizane ndi zosowa zosiyanasiyana zamafakitale komanso zothandiza.
Tsopano mwapeza kusiyana pakati pa Silicon Carbide ndi Tungsten Carbide mechanical seals, koma mwachionekere, kumvetsetsa chomwe chikugwirizana bwino ndi zida zanu zogwirira ntchito ndi ntchito zanu kungakhale kovuta. Luso limakonda anthu odziwa zambiri! Chifukwa chake onetsetsani kuti mwalandira upangiri wanzeru wogwirizana ndi zomwe makampani anu akufuna.
