Wakambozvibvunza here nezve musiyano pakati kabhoni uyesilicon carbide mechanical seals?Mune ino blog post, isu tinonyura mune yakasarudzika zvivakwa uye mashandisiro echimwe chinhu.Pakupera, iwe unenge uine kunzwisisa kwakajeka kwenguva yekusarudza kabhoni kana silicon carbide kune zvaunoda kuisa chisimbiso, ichikupa simba rekuita sarudzo dzine ruzivo mumapurojekiti ako.
Zvimiro zveCarbon Seal Faces
Carbon chinhu chinowanzo shandiswamechanical seal zvisonekuda kwemaitiro ayo akasiyana.Iyo inopa yakanakisa lubricating maitiro, ayo anobatsira kuderedza kupokana uye kupfeka pakati pechisimbiso zviso panguva yekushanda.Carbon inoratidzawo yakanaka yekupisa conductivity, ichiibvumira kuti ibvise kupisa zvakanaka uye kudzivirira yakawandisa tembiricha kuvaka pane yekuvharisa interface.
Imwe mukana wezviso zvekabhoni seal kugona kwavo kuenderana nekusakwana kudiki kana kusarongeka munzvimbo yekubatana.Uku kuchinjika kunovimbisa chisimbiso chakasimba uye kunoderedza kuvuza.Carbon zvakare inoshingirira kune akasiyana siyana emakemikari, ichiita kuti ive yakakodzera kushandiswa mumaindasitiri akasiyana siyana.
Zvimiro zveSilicon Carbide Seal Faces
Silicon carbide (SiC) ndiyo imwe sarudzo yakakurumbira yezviso zvemakanika chisimbiso nekuda kwekuoma kwayo kwakasarudzika uye kuramba kupfeka.Zviso zveSiC seal zvinogona kumirisana nemamiriro ekushanda akaomarara, kusanganisira kudzvanyirira kwakanyanya, tembiricha, uye abrasive media.Iyo yakakwira yekupisa conductivity inobatsira kubvisa kupisa, kudzivirira kukanganiswa kwemafuta uye kuchengetedza chisimbiso kutendeseka.
Zviso zveSiC seal zvinopawo zvakanakisa makemikari kuramba, zvichiita kuti zvive zvakakodzera kushandiswa munzvimbo dzinoparadza.Iyo yakatsetseka yepasi pekupedzisira yeSiC inoderedza kupokana uye kupfeka, kuwedzera hupenyu hwechisimbiso chemuchina.Pamusoro pezvo, SiC's high modulus ye elasticity inopa kugadzikana kwedimensional, kuve nechokwadi kuti zviso zvechisimbiso zvinoramba zvakati sandara uye zvakafanana panguva yekushanda.
Musiyano Pakati peCarbon neSilicon Carbide
Maumbirwo uye Chimiro
Carbon mechanical seals inogadzirwa kubva ku graphite, chimiro chekabhoni chinozivikanwa nekuzvinyuchidzira zvimiro uye kuramba kupisa uye kurwisa kwemakemikari.Iyo graphite inowanzo kuisirwa neresin kana simbi kuti iwedzere mashandiro ayo.
Silicon carbide (SiC) chinhu chakaoma, chinopfeka-chinodzivirira ceramic zvinhu zvinoumbwa nesilicon uye kabhoni.Iyo ine crystalline chimiro chinobatsira mukuoma kwayo kwakanyanya, kupisa kwemhepo, uye kugadzikana kwemakemikari.
Kuoma uye Wear Resistance
Silicon carbide yakanyanya kuoma kupfuura kabhoni, ine Mohs kuoma kwe9-9.5 zvichienzaniswa ne1-2 yegraphite.Uku kuomarara kwepamusoro kunoita kuti SiC irambe yakasimba kune abrasive kupfeka, kunyangwe mukuda maapplication ane abrasive media.
Zvisimbiso zveCarbon, nepo zvakapfava, zvichiri kupa kumira kwakanaka kwekupfeka munzvimbo dzisiri-abrasive.Iyo yekuzvizora yega ye graphite inobatsira kuderedza kupokana uye kupfeka pakati pezviso zvechisimbiso.
Temperature Resistance
Ose kabhoni uye silicon carbide ane yakanakisa yepamusoro-tembiricha zvivakwa.Carbon seals inogona kushanda patembiricha inosvika 350 ° C (662 ° F), nepo silicon carbide seals inogona kumira kunyangwe tembiricha yakakwira, kazhinji inodarika 500 ° C (932 ° F).
Thermal conductivity yesilicon carbide yakakwirira kudarika iyo kabhoni, ichibvumira SiC seals kuti iparadze kupisa zvakanyanya uye kuchengetedza yakadzika tembiricha yekushanda pane yekuisa chisimbiso.
Chemical Resistance
Silicon carbide ikemikari inert uye inoshingirira kurwisa kubva kune akawanda maasidhi, mabhesi, uye zvinonyungudutsa.Iyo isarudzo yakanakisa yekuvhara zvakanyanya corrosive kana hutsinye media.
Carbon inopawo kunaka kwemakemikari kuramba, kunyanya kune organic komisheni uye asiri-oxidizing asidhi nemabhesi.Nekudaro, inogona kunge isiri yakakodzera kune yakasimba oxidizing nharaunda kana maapplication ane yakakwirira-pH midhiya.
Mutengo uye Kuwanikwa
Carbon mechanical seals kazhinji isingadhure pane silicon carbide zvisimbiso nekuda kwemutengo wakaderera wezvigadzirwa uye maitiro akareruka ekugadzira.Carbon seals inowanikwa zvakanyanya uye inogona kugadzirwa mumhando dzakasiyana siyana uye zvigadziriso.
Silicon carbide seals inonyanya hunyanzvi uye inowanzouya pamutengo wepamusoro.Kugadzirwa kwemhando yepamusoro yeSiC zvikamu kunoda nzira dzepamusoro dzekugadzira uye kusimba kwehutongi hwemhando, zvichibatsira pakuwedzera mutengo.
Nguva Yekushandisa Carbon Seal
Carbon seal zviso zvakanakira zvikumbiro zvinosanganisira kudzikira kusvika pakati nepakati kumanikidza uye tembiricha.Iwo anowanzo shandiswa mumapombi emvura, musanganisi, uye agitators uko yekuisa chisimbiso midhiya isinganyanyi kushatisa kana kuora.Carbon zvisimbiso zvakakodzerawo kuvhara zvinwiwa zvine hurombo hwekuzora zvivakwa, sezvo iyo kabhoni iyo pachayo inopa lubrication.
Mune maapplication anogara achitanga-kumisa ma cycles kana uko shaft inosangana neaxial kufamba, kabhoni seal zviso zvinogona kugashira aya mamiriro nekuda kweayo ega ekuzora uye kugona kuenderana nekukanganisa kudiki munzvimbo yekubatana.
Nguva Yekushandisa Silicon Carbide Seal
Silicon carbide seal zviso zvinofarirwa mumashandisirwo anosanganisira yakanyanya kudzvanywa, tembiricha, uye abrasive kana corrosive media.Iwo anowanzo shandiswa mukuda maindasitiri maitiro, senge oiri negasi kugadzirwa, kugadzirwa kwemakemikari, uye kugadzirwa kwemagetsi.
Zvisimbiso zveSiC zvakakodzerwawo kuvhara mvura yakadzika-yakachena, sezvo isingasvibisi midhiya iri kuiswa chisimbiso.Mukushandisa uko midhiya yekuisa chisimbiso ine isina kunaka yekuzora zvivakwa, SiC yakaderera coefficient yekupokana uye kupfeka kuramba kunoita kuti ive sarudzo yakanaka.
Kana iyo mechanika chisimbiso ichiiswa pasi pekugara kuchinjika kwekushisa kana kupisa kwekushisa, SiC's high thermal conductivity uye dimensional kugadzikana kunobatsira kuchengetedza kushanda kwechisimbiso uye hupenyu hurefu.Pamusoro pezvo, zvisimbiso zveSiC zvakanakira zvikumbiro zvinoda hupenyu hurefu hwesevhisi uye kushomeka kwekugadzirisa nekuda kwekusimba kwazvo uye kuramba kupfeka.
