Tungsten Carbide bearings: Iyo Yekupedzisira Solution Yepamusoro-Performance Industrial Application

Munzvimbo yezvigadzirwa zvemaindasitiri, mabheya anoshanda semusanayekushanda kwakatsetseka, asi haasi ese mabhengi akagadzirwa akaenzana.Tungsten carbide bearingsdzakabuda semutambo-kuchinja, kupakusimba kusingaenzaniswi uye kuitaiyo inokunda zvigadzirwa zvechinyakare sesimbi kana ceramic. Inoumbwa ne tungsten carbide - inoumbwa ne tungsten uye kabhoni inozivikanwa nekuomarara kwayo (yechipiri kubva kudhaimondi) uye kuramba kupfeka - mabheji aya anogadzirwa kuti abudirirenzvimbo dzinoda zvakanyanya,zvichiita kuti zvive zvakakosha mumaindasitiri akakosha.

Imwe yeakanakisa mabhenefiti e tungsten carbide mabheji ndeye yavokuoma kwakasiyana, kuyerwa pa90-95 HRA (Rockwell Hardness Scale). Pfuma iyi inovagonesakushingirira mitoro inorema, kumhanya kwakakwirira, uye zvimedu zvinokuvadzapasina kukanganisa kana kupera, chinhu chakakosha kuzvikamu zvakaita semigodhi, oiri uye gasi, uye kugadzira. Mumabasa emigodhi, semuenzaniso, tungsten carbide mabearings emagetsi ekufambisa masisitimu uye macrusher, anogara achishingirira kupokana kubva mumamineral deposits uye guruva rakaomarara. Muindasitiri yemafuta negasi, vanokunda mumidziyo yekuchera pasi, kwavanodzivirira kukora kubva mumvura ine acid uye vanochengetedza kuvimbika pasi pekumanikidzwa kwakanyanya (kusvika ku10,000 psi) uye tembiricha (inodarika 300 ° C). Kusiyana nemabhengi esimbi, ayo anowanzoda kuchinjwa nguva nenguva nekuda kwekupfeka, tungsten carbide akasiyana anozvirumbidza hupenyu hunosvika kagumi, zvichideredza zvakanyanya mari yekugadzirisa uye kuderera kwemabhizinesi.

Imwe bhenefiti yakakosha ndeye yavosuperior corrosion resistance. Masimbi echinyakare mabearings anowanzoita ngura uye kuora kana akaiswa kune hunyoro, makemikari, kana mvura yemunyu, asi tungsten carbide inert hunhu hunoidzivirira kubva mukukuvadzwa kwakadaro. Izvi zvinoita kuti zvive zvakanaka kune zvikumbiro zvemugungwa, senge propeller shafts uye pombi dzepasi pemvura, pamwe nemakemikari ekugadziridza zvidyarwa uko mabearings anosangana nezvinonyungudutsa zvinopisa. Pamusoro pezvo, yavo yakaderera coefficient yekukwesha inovimbisa kutenderera kwakatsetseka kunyangwe nekumhanya kwakanyanya, kuderedza kurasikirwa kwesimba uye kusimudzira kushanda kwemuchina-chinhu chakakosha kumaindasitiri ari kuedza kudzikisa kabhoni tsoka nemitengo yekushandisa.

Nepo tungsten carbide bearings inopa kuita kunoshamisa, yavokugadzira uye kuisazvinoda kunyatsojeka. Vagadziri vanowanzoagadzirisa kune chaiwo maapplication, kugadzirisa zvinhu senge clearance, coating (semuenzaniso, diamond-senge kabhoni yekuwedzera lubricity), uye sealant mhando kuti ikwidze kushanda. Kugadzirisa kwakakodzera, sekuzora nguva dzose nemafuta ekupisa zvakanyanya, zvinowedzera kuwedzera hupenyu hwavo hwebasa.

Sezvo maindasitiri achiramba achisundidzira miganhu yekumhanya, mutoro, uye kusimba kwezvakatipoteredza, tungsten carbide mabearings akagadzirira kuita basa rakatonyanya kukosha. Kubva pamarobhoti ekugadzira epamberi kusvika kune anogonesa simba emagetsi senge majenareta emhepo, kugona kwavo kusanganisa kuomarara, kusaonda kwecorrosion, uye hupenyu hurefu hunovaita sarudzo yekuenda kune mainjiniya ari kutsvaga mhinduro dzakavimbika, dzepamusoro-soro. Munyika umo muchina unoshanda uye kusimba kunokanganisa zvakananga kugadzirwa uye pundutso, tungsten carbide mabheji anomira sechiratidzo chekuti sei.zvinhu zvitsva zvinogona kushandura mashandiro eindasitiri.
