I-Tungsten Carbide bearings: Isixazululo Esiphezulu Sezicelo Zezimboni Ezisebenza Kakhulu

Emkhakheni wemishini yezimboni, ama-bearings asebenza njenge-umgogodlaukusebenza kahle, kodwa akuwona wonke ama-bearings adalwe alinganayo.Ama-tungsten carbide bearingsziye zavela njengokushintsha kwegeyimu, ukunikelaukuqina nokusebenza okungenakuqhathaniswalokho kudlula izinto zendabuko njengensimbi noma i-ceramic. Yakhiwe nge-tungsten carbide—inhlanganisela ye-tungsten ne-carbon edume ngokuba lukhuni okwedlulele (isibili kuphela kwedayimane) kanye nokumelana nokugqokwa—lawa ma-bearings akhiwe ukuze achume endaweni.izindawo ezidinga kakhulu,okwenza zibe semqoka kuzo zonke izimboni ezibalulekile.

Enye yezinzuzo eziphawuleka kakhulu zama-tungsten carbide bearings yiwoubulukhuni obungavamile, kukalwa ku-90-95 HRA (Rockwell Hardness Scale). Lesi sici sibenza bakwaziukumelana nemithwalo esindayo, isivinini esikhulu, nezinhlayiya ezilumayongaphandle kokonakala noma ukuwohloka, isici esibalulekile emikhakheni efana nezimayini, uwoyela negesi, kanye nokukhiqiza. Emisebenzini yezimayini, isibonelo, amasistimu okuthutha amandla e-tungsten carbide nama-crusher, abekezelela ukungqubuzana okungapheli okusuka kumaminerali kanye nothuli oluqinile. Embonini kawoyela negesi, benza kahle kakhulu kumathuluzi okumba ama-downhole, lapho bemelana nokugqwala okuvela emanzini ane-asidi futhi bagcine ubuqotho ngaphansi kwengcindezi enkulu (kufika ku-10,000 psi) kanye namazinga okushisa (adlula ku-300 ° C). Ngokungafani namabheringi ensimbi, avame ukudinga ukushintshwa kaningi ngenxa yokuguga, okuhlukile kwe-tungsten carbide kuziqhayisa ngokuphila isikhathi esiphindwe izikhathi ezingu-10 ubude, kunciphisa kakhulu izindleko zokunakekela kanye nesikhathi sokuphumula samabhizinisi.

Enye inzuzo eyinhloko yiboukumelana nokugqwala okuphezulu. Izinsimbi zendabuko zijwayele ukugqwala futhi ziwohloke lapho zichayeka kumswakama, amakhemikhali, noma amanzi anosawoti, kodwa imvelo engasebenzi ye-tungsten carbide iyayivikela kulowo monakalo. Lokhu kuzenza zilungele ukusetshenziswa olwandle, njengama-propeller shafts namaphampu angaphansi kwamanzi, kanye nezindawo zokucubungula amakhemikhali lapho ama-bearings ehlangana khona nezincibilikisi ezibolayo. Ukwengeza, i-coefficient yabo ephansi yokungqubuzana iqinisekisa ukujikeleza okushelelayo ngisho nangesivinini esikhulu, kunciphisa ukulahlekelwa kwamandla futhi kuthuthukise ukusebenza kahle kwemishini—isici esibalulekile ezimbonini ezilwela ukunciphisa imilobo yekhabhoni nezindleko zokusebenza.

Ngenkathi ama-tungsten carbide bearings enikeza ukusebenza okumangazayo, awoukuklama nokufakwazidinga ukunemba. Abakhiqizi bavamise ukuzivumelanisa nezinhlelo zokusebenza ezithile, izici zokulungisa ezifana nokususa, ukunamathela (isb., ikhabhoni efana nedayimane ukuze uthole ukuthambisa okwengeziwe), kanye nohlobo lwesivali ukuze kuthuthukiswe ukusebenza. Ukugcinwa okufanele, njengokugcotshwa okujwayelekile ngamafutha ashisa kakhulu, kwandisa impilo yabo yesevisi.

Njengoba izimboni ziqhubeka nokuphusha imingcele yejubane, umthwalo, kanye nokusimama kwemvelo, ama-tungsten carbide bearings alungele ukudlala indima ebaluleke nakakhulu. Kusukela kumarobhothi akhiqizayo athuthukile kuye kumishini yamandla avuselelekayo njengamajeneretha eturbine yomoya, ikhono lawo lokuhlanganisa ubulukhuni, ukumelana nokugqwala, nokuphila isikhathi eside kuwenza abe yinketho yonjiniyela abafuna izixazululo ezinokwethenjelwa, ezisebenza kahle kakhulu. Ezweni lapho ukusebenza kahle kwemishini nokuqina kuthinta ngokuqondile ukukhiqiza kanye nenzuzo, ama-tungsten carbide bearings ame njengobufakazi bokuthiizinto ezintsha zingaguqula ukusebenza kwezimboni.
