Umahluko ophambili phakathi kweSilicon Carbide kunye neTungsten Carbide Mechanical Seals
Ukuthelekiswa kweePropati zeMzimba kunye nezeMichiza
I-Silicon Carbide, le khompawundi ibambe isakhiwo sekristale eyenziwe ngesilicon kunye neeathom zekhabhoni. Ibamba ukuhanjiswa kwe-thermal okungenakuthelekiswa nanto phakathi kwezixhobo zobuso betywina, ubunzima obuphezulu obubekwe kwi-9.5 kwisikali se-Mohs - okwesibini kuphela kwidayimane - kunye nepropathi egqwesileyo yokumelana nokuhlwa. I-SiC ikwayimathiriyeli ye-ceramic engeyiyo i-oksidi ekhokelela kukuqina okuphezulu ngenxa yeebhondi zayo ezithembekileyo ezikhule ngokubhekisele kuyo yonke into.
I-Tungsten Carbide yi-alloy eyenziwe ikakhulu yi-Tungsten kunye ne-Carbon element. Yenziwe ngenkqubo ebizwa ngokuba yi-sintering ekhokelela kumlinganiselo onzima kakhulu wezinto phakathi kwe-8.5-9 kwisikali se-Mohs - yomelele ngokwaneleyo malunga naso nasiphi na isicelo esiphoswe kuyo kodwa ingabi nzima njenge-SiC. Ukongeza ekubeni inxinana, iWC ibonakalisa iqondo elimangalisayo lobulukhuni malunga nobushushu; nangona kunjalo, ayizinzile kangako ngokwekhemikhali xa ithelekiswa neSilicon Carbide.
Umahluko kwiNtsebenzo phantsi kweeMeko ezahlukeneyo zokuSebenza
Xa kuthelekiswa ukusebenza kwe-silicon carbide (SiC) kunye ne-tungsten carbide (WC) itywina lomatshini phantsi kweemeko ezahlukeneyo zokusebenza, kubalulekile ukuxoxa ngempendulo yabo kwizinto ezifana nokushisa okugqithisileyo, ukuhluka koxinzelelo, i-corrosive media, kunye nokukwazi kwabo ukuphatha iimeko ezinobungozi.
Ngokubhekiselele ekuxhathiseni ubushushu, i-silicon carbide ibonisa i-thermal conductivity egqwesileyo kwaye inokusebenza ngokufanelekileyo kumaqondo obushushu aphezulu xa kuthelekiswa ne-tungsten carbide. Olu phawu lwenza i-SiC ibe lolona khetho lufanelekileyo kwizicelo apho ukunyamezela kobushushu obuphezulu kubalulekile.
Ngokuchasene noko, xa ucinga ngokumelana noxinzelelo, i-tungsten carbide ibamba inzuzo eyahlukileyo ngaphezu kwe-silicon carbide. Ubume bayo obuxineneyo buyenza ikwazi ukumelana neemeko zoxinzelelo olukhulu ngakumbi kuneSiC. Yiyo loo nto, izitywina zeWC zifaneleke ngakumbi kusetyenziso olunzima kunye noxinzelelo oluphezulu olubandakanyekayo.
Ngokuxhomekeke kumajelo osasazo asebenzayo apho la matywina avezwa khona, ukuxhathisa okunokonakala kuba yenye iparameter ebalulekileyo yovavanyo. I-silicon carbide igqwesa i-tungsten carbide ekuxhathiseni izisombululo ze-asidi kunye ne-alkaline ngenxa yobume bayo bokungangeni kweekhemikhali. Ke ngoko, izitywina zeSiC zikhethwa kumashishini ajongana nolwelo olunamandla okanye iigesi.
Ukumelana nokunxitywa phakathi kwezi ntlobo zimbini zetywina kubuyisela umva ukuthanda i-tungsten carbide ngenxa yokuqina kwayo okungaphakathi, iyenza ixhotyiswe ngcono ukumelana neemeko ezirhabaxa kwixesha elide lokusetyenziswa.
Uthelekiso lweendleko
Ngokuqhelekileyo, ixabiso lokuqala lexabiso le-tungsten carbide seals linokuba phezulu kune-silicon carbide equivalents ngenxa yokumelana kwayo okuphezulu kunye nokuqina kwayo. Nangona kunjalo, kubalulekile ukuqwalasela kungekuphela nje iindleko zangaphambili, kodwa kunye neendleko zokusebenza zexesha elide.
Ngelixa izitywina ze-tungsten carbide zinokufuna utyalo-mali olukhulu lokuqala, ixesha elide kunye nokusebenza kakuhle kunokuphelisa le ndleko yokuqala ngokuhamba kwexesha. Kwelinye icala, izitywina ze-silicon carbide zihlala zingabizi kakhulu ngaphambili nto leyo ezenza zibe lukhetho olunomtsalane kumashishini ajonga uhlahlo lwabiwo-mali. Nangona kunjalo, ngenxa yokunganyangeki kwabo okuphantsi kwiimeko ezithile, banokufuna ukutshintshwa rhoqo okanye ukulungiswa okukhokelela kwiindleko eziphezulu zexesha elide.
Umahluko eKuzinzeni kunye nokuNxitywa kweResistance
Izitywina zoomatshini zeSilicon Carbide zinobulukhuni obukhethekileyo obudityaniswa nokuhamba okuphezulu kwe-thermal. Le ndibaniselwano ibenza bangakwazi ukunxiba ngenxa yokruthakruthwano, kuncitshiswe amathuba abo okonakala naphantsi kweemeko ezinzima zokusebenza. Ngaphezu koko, ukuxhathisa kwabo ngokuchasene nokubola kweekhemikhali kwandisa ngakumbi ukuqina kwabo kukonke.
Kwelinye icala, iTungsten Carbide izitywini zoomatshini zinika amandla angenakuthelekiswa nanto kunye nobungqongqo, obubanceda ngokufanelekileyo ukumelana noxinzelelo olukhulu lomzimba ixesha elide. Ukuqina kwabo kuqinisekisa ukusebenza okungaguquguqukiyo naxa bephantsi kweemeko ezinzima, kuphakamisa ukuxhathisa kwabo ukunxiba kakhulu.
Zombini izixhobo zixhathisa ngokwendalo ukwandiswa kwe-thermal; nangona kunjalo, i-Silicon Carbide ibonisa ukuxhathisa ukothuka kancinci kwe-thermal xa kuthelekiswa neTungsten Carbide. Oku kuthetha ukuba izitywina ze-SiC azinakwenzeka ukuba ziqhekeke okanye zikhubazeke xa zibonakaliswe kwiinguqu ezikhawulezayo zeqondo lokushisa-into eyenza igalelo elihle ngokumalunga nokuqina.
Indlela yokukhetha phakathi kweSilicon Carbide kunye neTungsten Carbide Mechanical Seals
Ngokusisiseko, kubalulekile ukuqwalasela imeko apho amatywina aya kusebenza khona. Oko kuthathela ingqalelo izinto ezifana nobume benkqubo yolwelo, amanqanaba obushushu, amanqanaba oxinzelelo, kunye nokuba nokwenzeka kwazo naziphi na izinto ezidlekayo. I-WC ithathwa kakhulu ngenxa yobungqongqo kunye nokunyamezela ukuxhathisa ukunxitywa. Ngenxa yoko, inokukhethwa kwiindawo ezisingqongileyo ezifuna ukuqina ngokuchasene ne-abrasion okanye uxinzelelo olugqithisileyo.
Kwelinye icala, i-SiC ibonisa ukuxhathisa okugqwesileyo kumothuko we-thermal kunye ne-corrosion eyenza ilungele usetyenziso apho utshintsho olumandla lobushushu lulindeleke okanye ulwelo olunokutya olukhoyo. Iimpawu zayo eziphantsi zokusebenzisana ngokufanelekileyo zikwathetha ukusetyenziswa kwamandla okuncinci oko kwenza izitywina ze-SiC zilungele imisebenzi ebuthathaka amandla.
Ngaphaya koko, iingqwalasela zemali akufunekanga zingahoywa xa usenza olu khetho; ngelixa i-WC iqhayisa ngobulukhuni be-premium kunye neempawu zokumelana nokunxiba, ithande ukubiza kakhulu kunee-SiC. Ke ngoko, ukuba imiqobo yohlahlo lwabiwo-mali ingumba osisithintelo, ukukhetha i-SiC kunokuba sisisombululo esinokubakho ukuba akukho zimo zokusebenza zinzima/zonakalisayo.
Okokugqibela kodwa okubalulekileyo kukunyaniseka kohlobo lwakho okanye amava angaphambili nokuba yi-silicon carbide mechanical seals okanye i-tungsten carbide mechanical seals. Amanye amashishini ayaqhubeka nokusebenzisa ngokuxhomekeke kwidatha yembali okanye amava okusebenza adlulileyo okusebenzisa uhlobo oluthile ngaphezu kolunye olubonakala lunengqiqo ngokwembono yokuthembeka.
