Umehluko Obalulekile phakathi kweSilicon Carbide neTungsten Carbide Mechanical Seals
Ukuqhathaniswa Kwezakhiwo Zomzimba Nezamakhemikhali
I-Silicon Carbide, le nhlanganisela ibamba isakhiwo se-crystalline esakhiwe i-silicon nama-athomu e-carbon.Ine-thermal conductivity engenakuqhathaniswa phakathi kwezinto zobuso be-seal, ukuqina okuphezulu kukalwe ku-9.5 esikalini se-Mohs - okwesibili ngemuva kwedayimane - kanye nesakhiwo esihle kakhulu sokumelana nokugqwala.I-SiC futhi iyimpahla ye-ceramic engeyona i-oxide eholela ekuqineni okuphezulu ngenxa yezibopho zayo ezinokwethenjelwa ze-covalent ezikhule ngokuqondiswa kuyo yonke into.
I-Tungsten Carbide iyingxubevange eyakhiwe ikakhulukazi izakhi ze-Tungsten ne-Carbon.Idalwe ngenqubo ebizwa ngokuthi i-sintering eholela esilinganisweni esinzima kakhulu sezinto endaweni ethile phakathi kuka-8.5-9 esikalini se-Mohs - siqine ngokwanele kunoma yisiphi isicelo esiphonswe kuso kodwa hhayi kanzima njenge-SiC.Ngaphezu kokuba minyene, i-WC ikhombisa izinga elimangalisayo lokuqina eduze nokushisa;kodwa-ke, ayizinzile ngamakhemikhali uma iqhathaniswa ne-Silicon Carbide.
Umehluko Ekusebenzeni Ngaphansi Kwezimo Ezihlukahlukene Zokusebenza
Uma uqhathanisa ukusebenza kwe-silicon carbide (SiC) ne-tungsten carbide (WC) mechanical seals ngaphansi kwezindawo zokusebenza ezihlukene, kubalulekile ukuxoxa ngokusabela kwazo ezicini ezifana nokweqisa kwezinga lokushisa, ukuhluka kwengcindezi, imidiya ebolayo, kanye nekhono lazo lokusingatha izimo ezilimazayo.
Mayelana nokumelana nokushisa, i-silicon carbide ibonisa ukuhamba kahle kwe-thermal futhi ingasebenza ngokuphumelelayo emazingeni okushisa aphezulu uma kuqhathaniswa ne-tungsten carbide.Lesi sici senza i-SiC ibe inketho efanelekile yezinhlelo zokusebenza lapho ukubekezela kwezinga lokushisa eliphezulu kubalulekile.
Ngokuphambene nalokho, uma ucubungula ukumelana nengcindezi, i-tungsten carbide ibamba inzuzo ehlukile kune-silicon carbide.Ukwakheka kwayo okuminyene kuyenza ikwazi ukumelana nezimo zokucindezela okukhulu kune-SiC.Ngakho-ke, ama-WC seal afaneleka kakhulu izinhlelo zokusebenza ezinzima ezinengcindezi ephezulu ehilelekile.
Kuye ngemidiya esebenzayo lapho lezi zimpawu zivezwa khona, ukumelana nokugqwala kuba enye ipharamitha ebalulekile yokuhlolwa.I-Silicon carbide idlula i-tungsten carbide ekumelaneni nezixazululo ezine-asidi ne-alkaline ngenxa yemvelo yayo engenamakhemikhali.Ngakho-ke, ama-SiC seal akhethwa ezimbonini ezibhekene noketshezi olunamandla noma amagesi.
Ukumelana nokugqokwa phakathi kwalezi zinhlobo ezimbili zama-seals kubuyisela emuva kuvune i-tungsten carbide ngenxa yokuqina kwayo okungokwemvelo, okuyenza ihlomele kangcono ukuphatha izimo ezilimazayo esikhathini eside sokusetshenziswa.
Ukuqhathaniswa Kwezindleko
Imvamisa, iphoyinti lentengo lokuqala lezimpawu ze-tungsten carbide lingaba phezulu kunezilinganiso ze-silicon carbide ngenxa yezakhiwo zayo eziphakeme zokungagugi nobulukhuni.Kodwa-ke, kubalulekile ukuthi ungabheki nje kuphela izindleko zangaphambili, kodwa nezindleko zokusebenza zesikhathi eside.
Ngenkathi izimpawu ze-tungsten carbide zingadinga ukutshalwa kwezimali okukhulu kokuqala, ukuphila kwabo isikhathi eside nokusebenza kahle kungavala lezi zindleko zokuqala ngokuhamba kwesikhathi.Ngakolunye uhlangothi, ama-silicon carbide seal ngokuvamile awabizi kakhulu ngaphambili okuwenza abe inketho ekhangayo kumabhizinisi akhathalela isabelomali.Kodwa-ke, uma kubhekwa ukumelana kwabo okuphansi ngokuqhathaniswa nezimo ezithile, bangadinga ukushintshwa kaningi noma ukunakekelwa okuholela ezindlekweni eziphakeme zesikhathi eside.
Umehluko Ekuqiniseni Ukuqina kanye Nokumelana Nokugqoka
Izigxivizo zemishini ye-Silicon Carbide zinobulukhuni obukhethekile obuhambisana nokushisa okuphezulu.Le nhlanganisela ibenza bangabi lula ukugqoka ngenxa yokungqubuzana, kunciphisa amathuba abo okuguquka ngisho nangaphansi kwezimo ezinzima zokusebenza.Ngaphezu kwalokho, ukumelana kwazo nokugqwala kwamakhemikhali kuthuthukisa ukuqina kwazo kukonke.
Ngakolunye uhlangothi, izigxivizo zemishini ye-Tungsten Carbide zinikeza amandla angenakuqhathaniswa nokuqina, okubasiza ngempumelelo ukuthi bamelane nezingcindezi ezinkulu zomzimba isikhathi eside.Ukuqina kwabo kuqinisekisa ukusebenza okungaguquki ngisho nalapho bengaphansi kwezimo ezicindezelayo, kuphakamisa ukumelana kwabo kokugqoka kakhulu.
Zombili izinto ezisetshenziswayo zimelana ngokwemvelo nokwanda okushisayo;kodwa-ke, iSilicon Carbide ikhombisa ukumelana nokushaqeka okungcono kancane okushisayo uma kuqhathaniswa neTungsten Carbide.Lokhu kusho ukuthi izimpawu ze-SiC mancane amathuba okuba ziqhekeke noma ziwohloke lapho zichayeka ekushintsheni kwezinga lokushisa ngokushesha—isici esinikela kahle mayelana nokuqina.
Ungakhetha Kanjani Phakathi Kwe-Silicon Carbide ne-Tungsten Carbide Mechanical Seals
Ngokuyinhloko, kubalulekile ukucabangela indawo lapho ama-seal azosebenza khona.Lokho kucabangela izici ezifana nemvelo yoketshezi lwenqubo, amazinga okushisa, amazinga okucindezela, kanye nokuba nokwenzeka kwanoma yiziphi izici ezibolayo.I-WC ihlonishwa kakhulu ngenxa yokuqina kwayo nokumelana nokubekezeleleka ukugqokwa.Ngakho-ke, kungase kuthandeke ezindaweni ezidinga ukuqina ngokumelene nokuhuzuka noma ingcindezi enkulu.
Ngakolunye uhlangothi, i-SiC ikhombisa ukumelana okuhle nokushaqeka okushisayo nokugqwala okuyenza ilungele izinhlelo zokusebenza lapho kulindeleke khona izinguquko ezinqala kumazinga okushisa noma kukhona uketshezi olubola kakhulu.Izibaluli zayo ezisebenza ngokuhlanganyela ngokusebenza kahle kokungqubuzana ziphinde zisho ukusetshenziswa kwamandla okuncane ngaleyo ndlela kwenze izimpawu ze-SiC zilungele imisebenzi ezwela amandla.
Ngaphezu kwalokho, ukucatshangelwa kwezezimali akufanele kushaywe indiva lapho kwenziwa lokhu kukhetha;kuyilapho i-WC iziqhayisa ngobulukhuni be-premium kanye nezakhiwo zokumelana nokugqoka, ivame ukubiza kakhulu kunozakwabo be-SiC.Ngakho-ke, uma izithiyo zebhajethi ziyisici esikhawulelayo, ukukhetha i-SiC kungase kube yisixazululo inqobo nje uma zingekho izimo zokusebenza ezinzima/ezilimazayo.
Okokugcina okubalulekile ukwethembeka komkhiqizo wakho noma ulwazi lwangaphambilini nge-silicon carbide mechanical seal noma i-tungsten carbide mechanical seals.Amanye amabhizinisi ayaqhubeka nokusetshenziswa kuye ngedatha yomlando noma isipiliyoni sokusebenza esidlule sokusebenzisa uhlobo olulodwa ngaphezu kolunye olubonakala lunengqondo ngokombono wokwethembeka.
Ekuphetheni
Sengiphetha, i-Silicon Carbide ne-Tungsten Carbide mechanical seals ziyizixazululo ezimbili ezihlukene zokuphatha izinhlelo zokusebenza zemishini.Nakuba i-Silicon Carbide inikeza ukumelana nokushisa okuhlaba umxhwele nokuzinza kwamakhemikhali, i-Tungsten Carbide yaziwa ngokuhlala kwayo okuvelele namandla ngaphansi kwezimo ezimbi kakhulu.Ukukhetha kwakho phakathi kwalezi zinto ezimbili kufanele kuqondiswe yizidingo zakho ezithile kanye nezidingo zohlelo lokusebenza;asikho isixazululo sendawo yonke.Ithimba lethu lochwepheshe abangomakadebona kwa-XYZ Inc. lihamba phambili ekunikezeni izixazululo eziguquguqukayo ukuze zihambisane nezidingo zezimboni ezihlukahlukene ngempumelelo.
Manje usuwutholile umehluko phakathi kwe-Silicon Carbide ne-Tungsten Carbide mechanical seals, kodwa ngokusobala, ukuqonda ukuthi iyiphi eqondana kangcono nemishini yakho yokusebenza nemisebenzi kusengaba inselele.Inhlanhla ithanda ukwaziswa!Ngakho-ke qiniseka ukuthi uzihlomisa ngezeluleko zamasu ezifanelana nemininingwane yomkhakha wakho.
