Umahluko oPhambili phakathi kweSilicon Carbide kunye neTungsten Carbide Mechanical Seals
Uthelekiso lweePropati zePhysical kunye neeChemical
Le compound, eyiSilicon Carbide, ibambe isakhiwo sekristale esenziwe ngeeathom zesilicon kunye nekhabhoni. Ibamba ubushushu obungenakuthelekiswa nanto phakathi kwezinto zobuso betywina, ubunzima obuphezulu obulinganiswe kwi-9.5 kwisikali seMohs - okwesibini emva kwedayimani - kunye neempawu ezintle zokumelana nokugqwala. I-SiC ikwayinto yeceramic engeyiyo i-oxide ekhokelela ekuqineni okuphezulu ngenxa yeebhondi zayo ze-covalent ezithembekileyo ezikhulela kwicala kuyo yonke into.
I-Tungsten Carbide yi-alloy eyenziwe ikakhulu zizinto zeTungsten kunye neCarbon. Yenziwa ngenkqubo ebizwa ngokuba yi-sintering ekhokelela kuvavanyo lwezinto ezinzima kakhulu kwindawo ephakathi kwe-8.5-9 kwisikali seMohs - inzima ngokwaneleyo kuyo nayiphi na into efakwa kuyo kodwa ayinzima njengeSiC. Ukongeza ekubeni nkulu, i-WC ibonisa ukuqina okumangalisayo xa ijikeleze ubushushu; nangona kunjalo, ayizinzanga kangako kwiikhemikhali xa ithelekiswa neSilicon Carbide.
Umahluko ekusebenzeni phantsi kweemeko ezahlukeneyo zokusebenza
Xa kuthelekiswa ukusebenza kwe-silicon carbide (SiC) kunye ne-tungsten carbide (WC) mechanical seals phantsi kweemeko ezahlukeneyo zokusebenza, kubalulekile ukuxoxa ngempendulo yazo kwizinto ezifana nobushushu obugqithisileyo, utshintsho loxinzelelo, imidiya erhabaxa, kunye nokukwazi kwazo ukujongana neemeko ezirhabaxa.
Ngokuphathelele ukumelana nobushushu, i-silicon carbide ibonisa ukuhanjiswa kobushushu okugqwesileyo kwaye inokusebenza ngokufanelekileyo kumaqondo obushushu aphezulu xa kuthelekiswa ne-tungsten carbide. Olu phawu lwenza i-SiC ibe lukhetho olufanelekileyo lokusetyenziswa apho ukunyamezela ubushushu obuphezulu kubalulekile.
Ngokwahlukileyo koko, xa kucingwa ngokumelana noxinzelelo, i-tungsten carbide inenzuzo eyahlukileyo kune-silicon carbide. Ulwakhiwo lwayo oluxineneyo luyenza ikwazi ukumelana neemeko zoxinzelelo olugqithisileyo ngcono kune-SiC. Ngenxa yoko, ii-WC seals zilungele ngakumbi ukusetyenziswa kobunzima obuphezulu kunye noxinzelelo oluphezulu.
Ngokuxhomekeke kwimidiya yokusebenza apho ezi zitywini zibonakala khona, ukumelana nokubola kuba lolunye uphawu olubalulekileyo lovavanyo. I-silicon carbide idlula i-tungsten carbide ekumelaneni nezisombululo ze-asidi kunye ne-alkaline ngenxa yendalo yayo yokungangenisi iikhemikhali. Ke ngoko, izitywini ze-SiC zikhethwa kakhulu kumashishini ajongene nolwelo olunamandla okanye iigesi.
Ukumelana nokuguguleka phakathi kwezi ntlobo zimbini zezitywini kubuyela umva kusetyenziswa i-tungsten carbide ngenxa yobunzima bayo bendalo, nto leyo eyenza ukuba ixhotyiswe ngcono ukujongana neemeko ezirhabaxa ngexesha lokusetyenziswa ixesha elide.
Uthelekiso lweendleko
Ngokwesiqhelo, ixabiso lokuqala le-tungsten carbide seals linokuba phezulu kune-silicon carbide equivalents ngenxa yokuba ayigugi kakuhle kwaye ayigugi. Nangona kunjalo, kubalulekile ukuqwalasela kungekuphela nje iindleko zangaphambili, kodwa kunye neendleko zokusebenza zexesha elide.
Nangona ii-tungsten carbide seals zinokufuna utyalo-mali olukhulu lokuqala, ukuhlala ixesha elide kunye nokusebenza kakuhle kwazo kunokunciphisa iindleko zokuqala ngokuhamba kwexesha. Kwelinye icala, ii-silicon carbide seals zihlala zingabizi kakhulu kwangaphambili nto leyo eyenza zibe lukhetho olunomtsalane kumashishini acinga ngebhajethi. Nangona kunjalo, ngenxa yokumelana kwazo nokuguguleka okuphantsi kwiimeko ezithile, zinokufuna ukutshintshwa rhoqo okanye ukulungiswa okukhokelela kwiindleko eziphezulu zexesha elide.
Umahluko ekuQinisekeni nasekuNqabeni
Izitywina zeSilicon Carbide mechanical zinobunzima obungaqhelekanga kunye nokuqhuba okuphezulu kobushushu. Olu dibaniso luzenza zingagugi ngenxa yokungqubana, nto leyo enciphisa amathuba azo okuguquka nokuba phantsi kweemeko ezinzima zokusebenza. Ngaphezu koko, ukumelana kwazo nokugqwala kweekhemikhali kuphucula ngakumbi ukuqina kwazo ngokubanzi.
Kwelinye icala, izitywina zeTungsten Carbide mechanical zinika amandla nokuqina okungenakuthelekiswa nanto, nto leyo enceda ukuba zikwazi ukumelana noxinzelelo olukhulu lomzimba ixesha elide. Ukuqina kwazo kuqinisekisa ukusebenza rhoqo nokuba ziphantsi kweemeko ezinzima, nto leyo ephakamisa kakhulu ukumelana kwazo nokuguguleka.
Zombini ezi zinto ziyakwazi ukumelana nokwanda kobushushu; nangona kunjalo, iSilicon Carbide ibonakalisa ukumelana nokutshiswa kobushushu okungcono kancinci xa kuthelekiswa neTungsten Carbide. Oku kuthetha ukuba iiSiC seals azinakwenzeka ukuba ziqhekeke okanye ziguquguquke xa zivezwa kutshintsho olukhawulezileyo lobushushu—into enegalelo elihle ngokuqina.
Indlela yokukhetha phakathi kweSilicon Carbide kunye neTungsten Carbide Mechanical Seals
Ngokuyintloko, kubalulekile ukuqwalasela imeko-bume apho izitywina ziya kusebenza khona. Oko kuthathela ingqalelo izinto ezifana nohlobo lolwelo lwenkqubo, ububanzi bobushushu, amanqanaba oxinzelelo, kunye nokuba kunokwenzeka naziphi na izinto ezirhabaxa. I-WC ixatyiswa kakhulu ngenxa yokuqina kwayo kunye nokumelana nokuguguleka. Ngenxa yoko, inokuthandwa kwiindawo ezifuna ukuqina ngokuchasene nokukrala okanye uxinzelelo olugqithisileyo.
Kwelinye icala, iSiC ibonakalisa ukumelana okuhle kakhulu noxinzelelo lobushushu kunye nokugqwala okwenza ukuba ilungele ukusetyenziswa apho kulindeleke utshintsho olukhulu kubushushu okanye kukho ulwelo olugqwalisayo kakhulu. Iimpawu zayo eziphantsi zokusebenzisana kakuhle zikwathetha ukusetyenziswa kwamandla amancinci ngaloo ndlela zenza ukuba izitywini zeSiC zilungele imisebenzi ebuthathaka kumandla.
Ngaphezu koko, izinto eziqwalaselwayo ngemali akufuneki zingananzwa xa kusenziwa olu khetho; nangona i-WC ineempawu zokuqina okuphezulu kunye nokumelana nokuguguleka, idla ngokuba nexabiso eliphantsi kunee-SiC. Ke ngoko, ukuba imida yohlahlo-lwabiwo mali iyinto ethintelayo, ukukhetha i-SiC kunokuba sisisombululo esinokwenzeka ukuba akukho meko yokusebenza inzima/eyonakalisayo.
Okokugqibela kodwa okubalulekileyo kukuthembeka kophawu lwakho okanye amava angaphambili ngee-silicon carbide mechanical seals okanye ii-tungsten carbide mechanical seals. Amanye amashishini ayaqhubeka nokusebenzisa ngokuxhomekeke kulwazi lwembali okanye amava okusebenza angaphambili okusebenzisa uhlobo oluthile kunolunye olubonakala lufanelekile ngokwembono yokuthembeka.
