Ndeipi basa remotokari valve chisimbiso
Basa guru revhavhavhavhavha chisimbiso ndere kuve nechokwadi chekubatana kwepedyo pakati pevharuvhu nechigaro chevhavha kudzivirira kubuda kwegasi, kuitira kuve nechokwadi chekushanda kwakajairika uye kushanda kweinjini. ,
Mavharuvhu asina kuvharwa zvakanaka anogona kukonzera matambudziko akasiyana, anosanganisira:
Performance degradation : isina kunaka vharafu chisimbiso chinotungamira mukudonha kwemhepo, kukanganisa kushanda kwakajairwa kweinjini, uyezve kuderedza kuita kwese kwemotokari.
Mechanical kutadza : kuvharika kwenguva refu kuvharika kunogona kutungamira mukupfeka kwevharuvhu uye chigaro chevharuvhu, uye zvinototungamira mukutadza kwakanyanya kwemuchina.
Kuwedzera kushandiswa kwemafuta: kubuda kwemhepo kunotungamira mukupisa kusina kukwana, kuwedzera kushandiswa kwemafuta, kuderedza hupfumi hwemafuta.
Dambudziko rekuburitsa : Lax seal inogona kukanganisa maemission controls uye inogona kukonzera kuburitsa kwakawanda.
Kuti uone kusimba kwevhavha, matanho anotevera anogona kutorwa:
Iko kushandiswa kwezvinhu zvemhando yepamusoro uye chaiyo machining tekinoroji: yakakwira mhando yevharuvhu tekinoroji uye chaiyo machining tekinoroji inogona kuderedza gaka riri pakati pevharuvhu nechigaro chevharuvhu, kunatsiridza chisimbiso.
Kugara uchigadzirisa uye kutsiva zvikamu zvakasakara: kutsiva panguva yakakodzera kweakasakara mavharuvhu emafuta zvisimbiso uye zvimwe zvisimbiso kudzivirira mafuta kuti asapinde mukamuri yevharuvhu, zvichikanganisa kuvhara kwevhavha.
kuisirwa nekugadzirisa kwakaringana: kuve nechokwadi chekuti chitubu chevharuvhu chitubu chiri pakati nepakati uye kwakaringana kuisirwa, kudzivirira nekuda kwekusakwana kwechirimo chitubu kana kuisirwa zvisina kunaka kunokonzerwa nekuvhara kwakadzika.
Automotive valve seal inoreva kugona kwevharuvhu kuchengetedza mvura yepakati kuti isayerera kana yakavharwa. Mavharuvhu zvisimbiso anogona kukamurwa zvichienderana nechimiro uye chinzvimbo chenzvimbo yekuisa chisimbiso uye kutungamira kwekuyerera kwepakati, kunyanya yakakamurwa kuva anotevera marudzi:
Metal seal : Kushandiswa kwemakanika deformation uye deformation yepurasitiki pakati pemasimbi ekuisa chisimbiso vharafu, yakakodzera kupisa kwakanyanya uye nguva dzekumanikidza.
chisimbiso chakapfava : Kushandiswa kwezvinhu zvekudzivirira, rabha, mapurasitiki uye zvimwe zvinhu zvinochinjika sezvikamu zvekuisa chisimbiso, zvakafanira kushandiswa kwakaderera, senge indasitiri yemakemikari uye indasitiri yezvokurapa.
Sleeve seal : chisimbiso chemuchina, chakakodzera kupisa kwakanyanya uye kudzvanywa kana necorrosive media.
Valve sealing performance test
Kuti uve nechokwadi chekuisa chisimbiso chevhavha, bvunzo dzinoenderana dzinofanirwa kuitwa, kunyanya kusanganisira:
Air tightness test : Tarisa kana paine kuvuza nekuzadza imwe kudzvanywa kwegasi muvharuvhu.
liquid tightness test : zadza vharafu neimwe dzvinyiriro yemvura kuti uone kana paine kuvuza uye giredhi rekuvharisa revhavha.
Kuedza kwesimba : tarisa simba rekumanikidza uye kutakura simba revhavha kuti uone kuti haizokuvadzwa nematambudziko enyama.
Valve sealing tekinoroji kuvandudzwa
Valve sealing tekinoroji inonyanya kusanganisira kuisa chisimbiso chechigaro uye disc sealing zvikamu zviviri. Mumakore achangopfuura, nekufambira mberi kwesainzi, kugadzira tekinoroji uye dhizaini pfungwa, tekinoroji yekuisa chisimbiso chevharuvhu yakafambira mberi zvinoshamisa. Kushandiswa kwezvinhu zvitsva zvekuisa chisimbiso zvakadai sepolytetrafluoroethylene (PTFE), polyurethane, polyformaldehyde uye zvimwe zvinhu zvepolymer, pamwe nekugadzirisa kwekugadzira chisimbiso dhizaini uye kushandiswa kwehungwaru yekudzora tekinoroji, inoita kuti kuvhara kwevharuvhu kuve kwakagadziridzwa zvakanyanya.
Kana iwe uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pathiri saiti!
Ndapota tifonere kana uchida zvigadzirwa zvakadaro.
