Kusiyana Kwakakosha Pakati peSilicon Carbide neTungsten Carbide Mechanical Seals
Kuenzanisa kweZvinhu zveMuviri neMakemikari
Silicon Carbide, chinhu ichi chine chimiro chekristaro chakagadzirwa nemaatomu esilicon necarbon. Chine thermal conductivity isingaenzaniswi pakati pezvinhu zvechisimbiso, kuomarara kwakanyanya kwakaenzana ne9.5 pachikero cheMohs - chechipiri kubva kudhaimani - pamwe nehukuru hwakanaka hwekudzivirira ngura. SiC zvakare chinhu checeramic chisina oxide chinoita kuti chive chakasimba nekuda kwezvisungo zvayo zve covalent zvinokura zvakananga mukati mechinhu chose.
Tungsten Carbide imhando yesimbi inoumbwa nezvinhu zveTungsten neCarbon. Inogadzirwa kuburikidza nemaitiro anonzi sintering ayo anoguma nekuongororwa kwezvinhu zvakaoma zvikuru pakati pe8.5-9 paMohs scale — yakasimba zvakakwana kune chero chinhu chinoiswa pairi asi kwete yakasimba seSiC. Kuwedzera pakuva yakasimba, WC inoratidza kusimba kwakanyanya pakupisa; zvisinei, haina kugadzikana zvakanyanya mumakemikari kana ichienzaniswa neSilicon Carbide.
Kusiyana Kwekushanda Pasi Pemamiriro Akasiyana-siyana Ekushanda
Pakuenzanisa mashandiro esilicon carbide (SiC) netungsten carbide (WC) mechanical seals pasi penzvimbo dzakasiyana dzekushanda, zvakakosha kukurukura maitiro azvo kune zvinhu zvakaita sekupisa kwakanyanya, kushanduka kwekumanikidzwa, corrosive media, uye kugona kwadzo kubata mamiriro ekukwesha.
Panyaya yekudzivirira kupisa, silicon carbide inoratidza kufambisa kupisa kwakanaka uye inogona kushanda zvinobudirira pakupisa kwakakwira zvichienzaniswa netungsten carbide. Hunhu uhwu hunoita kuti SiC ive sarudzo yakakodzera yekushandisa uko kutsungirira kupisa kwakanyanya kwakakosha.
Kusiyana neizvi, kana tichifunga nezvekudzivirira kumanikidzwa, tungsten carbide ine mukana wakasiyana pane silicon carbide. Maumbirwo ayo akaomarara anoita kuti ikwanise kutsungirira mamiriro ekumanikidzwa kwakanyanya zviri nani pane SiC. Saka, WC seals dzakakodzera kushandiswa zvine simba guru uye dzine kumanikidzwa kwakanyanya.
Zvichienderana nechinhu chinoshanda chinoonekwa ma seal aya, kuramba kunopisa kunova chimwe chinhu chakakosha pakuongorora. Silicon carbide inopfuura tungsten carbide pakurwisa acidic uye alkaline solutions nekuda kwekusashanda kwayo nemakemikari. Saka, ma seal eSiC anofarirwa mumaindasitiri anobata mvura kana magasi ane hukasha.
Kusapera kwemhando mbiri idzi dzezvisimbiso kunodzokera shure nekuda kwekuoma kwayo kwekuzvarwa, zvichiita kuti ive yakashongedzerwa zviri nani kubata mamiriro ekukwesha kwenguva refu.
Kuenzanisa Mutengo
Kazhinji, mutengo wekutanga we tungsten carbide seals unogona kunge wakakwira kupfuura silicon carbide equivalents nekuda kwesimba rayo rekudzivirira kupfeka uye kuomarara. Zvisinei, zvakakosha kufunga kwete chete nezvemitengo yekutanga, asiwo nezvemitengo yenguva refu yekushandisa.
Kunyange hazvo tungsten carbide seals zvingada mari yakawanda yekutanga, kugara kwenguva refu uye kushanda zvakanaka kunogona kuderedza mari iyi yekutanga nekufamba kwenguva. Kune rumwe rutivi, silicon carbide seals dzinowanzo kudhura zvishoma pakutanga izvo zvinoita kuti dzive sarudzo inokwezva mabhizinesi ane hanya nebhajeti. Zvisinei, zvichipiwa kuti hadzina simba rakawanda rekupfeka mumamiriro ezvinhu akati wandei, dzinogona kuda kudzoserwa kana kugadziriswa kakawanda zvichikonzera mitengo yakakwira yenguva refu.
Kusiyana Kwekugara Kwenguva refu uye Kuramba Kupfeka
Zvisimbiso zveSilicon Carbide zvine kuomarara kwakanyanya pamwe chete nekupisa kwakanyanya. Musanganiswa uyu unoita kuti zvisanyanya kusakara nekuda kwekukweshana, zvichideredza mikana yazvo yekushanduka-shanduka kunyangwe mumamiriro ekushanda akaoma. Uyezve, kuramba kwadzo kurwisa ngura yemakemikari kunowedzera kugara kwadzo kwenguva refu.
Kune rumwe rutivi, Tungsten Carbide mechanical seals inopa simba risingaenzaniswi uye kuomarara, izvo zvinovabatsira kutsungirira kumanikidzwa kwakanyanya kwemuviri kwenguva yakareba. Kusimba kwavo kunoita kuti vagare vachiita basa ravo zvakanaka kunyangwe kana vakasangana nemamiriro ezvinhu akaoma, zvichiwedzera kuramba kwavo kupfeka zvakanyanya.
Zvinhu zvose izvi zvinodzivirira kupisa kwakanyanya; zvisinei, Silicon Carbide inodzivirira kupisa zvishoma kana tichienzanisa neTungsten Carbide. Izvi zvinoreva kuti SiC seals hadzina mukana wekutsemuka kana kukanganisika kana dzichisangana nekuchinja kwekupisa nekukurumidza—chinhu chinobatsira zvikuru pakugara kwenguva refu.
Maitiro Ekusarudza Pakati peSilicon Carbide neTungsten Carbide Mechanical Seals
Chinonyanya kukosha, zvakakosha kufunga nezvenzvimbo iyo zvisimbiso zvichashanda. Izvi zvinotarisa zvinhu zvakaita semhando yemvura inoyerera, tembiricha, mwero wekumanikidzwa, uye mukana wezvinhu zvinoparadza. WC inoremekedzwa zvikuru nekuda kwekuoma kwayo uye kuramba kwayo kupfeka. Saka, inogona kudiwa munzvimbo dzinoda kusimba kubva pakukweshwa kana kumanikidzwa kwakanyanya.
Kune rumwe rutivi, SiC inodzivirira kupisa kwakanyanya uye ngura zvinoita kuti ive yakakodzera kushandiswa kana paine shanduko huru mukupisa kana paine mvura inoparadza zvakanyanya. Hunhu hwayo hushoma hwekukweshana hunorevawo kuti haishandisi simba rakawanda, zvichiita kuti SiC seals ikodzere kushandiswa zvisina simba.
Uyezve, nyaya dzemari hadzifanirwe kuregeredzwa pakusarudza uku; nepo WC ichiratidza kuomarara kwayo uye hunhu hwayo hunodzivirira kupfekwa, inowanzo kudhura kupfuura SiC. Saka, kana zvipingamupinyi zvebhajeti zviri chinhu chinodzikisira, kusarudza SiC kungave mhinduro inogoneka chero bedzi pasina mamiriro ekushanda akakomba/anokuvadza.
Chekupedzisira asi chakakosha ndechekutendeka kwerudzi rwako kana ruzivo rwekare nesilicon carbide mechanical seals kana tungsten carbide mechanical seals. Mamwe mabhizinesi anoramba achishandisa zvichienderana neruzivo rwekare kana ruzivo rwekare rwekushandisa imwe mhando kupfuura imwe zvinoita sekunge zvine musoro kubva pamaonero ekuvimbika.
Mukupedzisa
Mukupedzisa, Silicon Carbide neTungsten Carbide mechanical seals mhinduro mbiri dzakasiyana dzekugadzirisa mashandisirwo emakanika. Kunyange zvazvo Silicon Carbide ichidzivirira kupisa uye kugadzikana kwemakemikari, Tungsten Carbide inozivikanwa nekusimba kwayo kwakanyanya mumamiriro ezvinhu akaoma.
