Une mamiriro ekunze akanyanya kupisa, makemikari, kana kukweshana kwakaderera? Dzidza kuti maPTFE seals (Variseals) anoshanda sei muchirimo uye kuti sei ari mhinduro yakavimbika yekushandiswa kwakaoma mundege, mota, uye kugadzira.
Nhanganyaya: Miganhu yeUinjiniya yeElastomeric Seals
Muinjiniya inoshanda zvakanyanya, chikamu chekuvharira chinowanzova chinhu chakakosha chinosarudza kuvimbika kwesystem. Kunyange hazvo zvisimbiso zverabha zvakaita seO-rings zvichishanda zvakanaka mumabasa mazhinji, zvinosvika pamiganhu yazvo kana zvasangana nekupisa kwakanyanya, makemikari ane hukasha, kufamba kwesimba, kana zvinodiwa zvekukweshana kwakaderera. Matambudziko aya anoda mhinduro inosanganisa hunhu hwepamusoro hwemapolymers epamusoro nesimba rekuvharira risingaperi.
Iyi ndiyo nzvimbo yechisimbiso chine simba rechitubu (chinowanzozivikanwa seChisimbiso cheVariseal kana Chisimbiso cheChitubu). Chinyorwa chino chinopa ruzivo rwakadzama pamusoro pekushanda kwechisimbiso ichi, matambudziko makuru achinogadzirisa, uye zvinhu zvakakosha zvekugadzira mainjiniya anotsanangura zvisimbiso munzvimbo dzinoda simba.
1. Nheyo Yekutanga: Kubatana kweChitubu nePolymer
Chisimbiso chine simba rechitubu sisitimu ine zvikamu zviviri zvakagadzirwa nemazvo:
Jekete rePolymer: Kazhinji muromo wechisimbiso wakaita seU wakagadzirwa nePTFE (Teflon®) kana mamwe mapolymer anoshanda zvakanyanya sePEEK kana UHMWPE. Jekete iri rinopa mukana wekutanga wekuvharira, zvichishandisa kusagadzikana kwemakemikari echinhu chacho, tembiricha yakakura, uye kukweshana kwakaderera zvakanyanya.
Chitubu Chinopa Simba: Chitubu chine denderedzwa, chinowanzogadzirwa nesimbi isingatsvi kana zvinhu zvinoshanda zvakanyanya seElgiloy®, chiri mukati meU-channel yejaketi.
Maitiro ekuvhara anobudirira zvikuru:
1. Chitubu chinopa simba re radial risingaperi, rakagara ratemwa, richisundira muromo wejaketi pagomba kana pamadziro egland.
2. Kana kumanikidzwa kwesystem kwaiswa, kunoshanda pachisimbiso, zvichiwedzera kumanikidzwa kwemuromo pamusoro pechinobatana. Izvi zvinogadzira chisimbiso chakavimbika uye chine simba rekumanikidzwa.
3Basa guru rechitubu nderekugadzirisa kusakara kwezvinhu (abrasion) uye kuchengetedza simba rekuvharisa kunyangwe paine kusarongeka kudiki kwehurongwa, kusagadzikana, kana shanduko dzinokonzereswa nekupisa. Izvi zvinoita kuti chisimbiso chishande zvakanaka muhupenyu hwese hwebasa racho.
2. Matambudziko Akakosha Ekushandisa uye Magadzirirwo Awo Ezvisimbiso Zvinoshandiswa Nesimba reChirimo
Iyi tekinoroji yakagadzirirwa kugadzirisa matambudziko chaiwo einjiniya anodhura:
Dambudziko: Kupisa Kwakanyanya uye Kuyerera Kwechando kwePTFE.
Mamiriro: Kuvhara mvura dzinopisa dzakadai senitrogen yemvura (-200°C) kana mvura dzinopisa zvakanyanya (>200°C).
Mhinduro: PTFE inochengetedza hunhu hwayo munzvimbo dzakasiyana-siyana dzekupisa uko ma elastomers anokundikana. Zvisinei, PTFE inowanzoitika mu "kuyerera kwechando" - kushanduka kwemvura kana ichinge yazara. Chitubu chemukati chinodzivirira kukwira uku, chichichengetedza kumanikidzwa kwemiromo uye chinodzivirira kutadza kushanda kwesero nekufamba kwenguva.
Dambudziko: Nzvimbo Dzakakasharara dzeMakemikoro kana dzePlasma.
Mamiriro: Kuvhara zvinonyungudutsa zvakasimba, maasidhi, mabhesi, kana mumidziyo yekugadzira wafer ye semiconductor neplasma inoparadza.
Mhinduro: PTFE haina makemikari akawanda, ichidzivirira zvakanyanya mhando dzakasiyana dzezvinhu zvinopisa. Izvi zvinoita kuti zvisimbiso zvinoshandisa simba remuchirimo zvive zvakanaka pakugadzirisa makemikari, mishonga, uye kushandiswa kwe semiconductor.
Dambudziko: Mashandisirwo Anoshanduka Nemafuta Akaderera/Asina Kunyoroveswa.
Mamiriro: Michina inotenderera inomhanya zvikuru mumidziyo yemhando yepamusoro, mumakamuri ekuchenesa, kana kushandiswa uko mafuta asingadiwi.
Mhinduro: Kunyorovesa kwechisikigo kwePTFE kunoita kuti zvisimbiso izvi zvishande zvisina kukweshana kwakanyanya uye kusakara, kunyangwe munzvimbo dzakaoma kana dzisina mafuta akawanda. Izvi zvinoderedza kushandiswa kwesimba uye kugadzirwa kwekupisa.
Dambudziko: Kuvimbika Kwenguva Refu Nekuchengetedza Kushoma.
Mamiriro: Inovhara munzvimbo dzisingasvikiki kana mumapurogiramu uko nguva yekusashanda isina kurongwa inodhura zvakanyanya.
Mhinduro: Simba risingaperi rechitubu rinotsiva miromo yakasakara, zvichiita kuti chisimbiso chive "chinozvigadzirisa chega." Izvi zvinoreva kuti nguva dzebasa dzakareba uye nguva yepakati pakati pekukundikana (MTBF) yakawedzera, zvichideredza mari yese yekuva muridzi.
3. Dhizaini Yakakosha uye Sarudzo Yezvinhu Kuti Uite Zvakanaka
Kusarudza chisimbiso chakakodzera chinoshandiswa nesimba remuchirimo hakusi chinhu chakajairika; zvinoda kunyatsofungisisa zvinhu zvakati wandei:
Zvinhu zveJaketi:
Virgin PTFE: Chiyero chekushandiswa kwemakemikari akawanda uye tembiricha.
PTFE yakazadzwa (semuenzaniso, neGirazi, Kabhoni, Graphite, Bronze): Inoshandiswa kuwedzera kusakara, kuderedza kuyerera kwemvura inotonhora, kuvandudza kupisa, kana kuwedzera kuomarara.
Mamwe maPolymer (PEEK, UHMWPE): Akasarudzwa nekuda kwezvinodiwa chaizvo zvakaita sesimba repamusoro remakanika (PEEK) kana resistance yepamusoro yeabrasion (UHMWPE).
Rudzi rweChitubu uye Zvinhu:
Simba reChitubu: Masipiringi akareruka, ari pakati nepakati, kana anorema anosarudzwa zvichienderana nekumanikidzwa, kumhanya, uye kukweshana kunodiwa.
Zvinhu zveChitubu:
Simbi Isina Chinovhara (302, 316): Yekudzivirira ngura.
Elgiloy®/Hastelloy®: Kune nzvimbo dzinonyanya kuoma dzinoda kuramba kukanganiswa negomba, tembiricha yakakwira, uye mvura inoparadza yakaita semvura yemunyu.
Geometry yeChisimbiso: Dhizaini yeU-cup inogona kugadziriswa kuti ikwanise kutenderera, kudzokorodza, kana kuti kugadzikana. Zvinhu zvakaita sekona yemuromo, kureba kwechitsitsinho, uye ukobvu hwejaketi zvakakosha uye zvinonyanya kusarudzwa kana tichibvunzana nemugadziri ane ruzivo.
4. Musiyano Mukugadzira: Nei Kunyatsokosha
Kushanda kwepfungwa kwechisimbiso chine simba rechitubu kunowanikwa chete kuburikidza neunyanzvi hwekugadzira. Masipiringi asingachinji kana majaketi asina michina zvakanaka zvinoita kuti zvisashande zvakanaka nguva isati yakwana. Zvikamu zvikuru zvekugadzira zvinosanganisira:
Kugadzira Majaketi Nemazvo: Jaketi rePTFE rinofanira kugadzirwa nemazvo, kwete kungoburitswa chete, kuti rikwanise kushivirira zvakanaka uye kupedzisa kwepamusoro-soro pamuromo unovhara. Muromo wakatsetseka uye wakafanana wakakosha kuti pave nekukweshana kushoma uye kuvharwa zvakanaka.
Kuenderana Kwechitubu: Chitubu chinofanira kumonerwa zvichienderana nezvinodiwa chaizvo, zvichiita kuti simba riparadzirwe zvakaenzana kutenderedza chisimbiso chose. Kuenderana kwechikamu chimwe nechimwe hakugone kutaurirana.
Kudzora Hunhu Zvakasimba: Batch yega yega yekugadzira inofanirwa kuongororwa nehukuru uye kupihwa chitupa chezvinhu. Kutevedza kubva pazvinhu zvakagadzirwa kusvika kune zvakagadzirwa zvinopa vimbiso yehunhu uye kutevedzera mitemo (semuenzaniso, neROHS, REACH).
Mhedziso: Kutsanangura Chisimbiso Chakakodzera Chekuvimbika Kwazvo
Zvisimbiso zvinoshandisa simba remuchirimo mhinduro yakasimbiswa uye yakavimbika zvikuru yekushandisa apo ma elastomer akajairwa haashande zvakanaka. Kugona kwavo kushanda mumamiriro ezvinhu akaomarara uku vachideredza mari yekugadzirisa kwenguva refu kunoita kuti vave mari yeinjiniya yakangwara.
Kubudirira kunoenderana nekunzwisisa zvinodiwa neapplication uye kushanda pamwe chete nemutengesi anonyatsonzwisisa zvinhu zvakasiyana-siyana uye kugadzira zvinhu nemazvo.
Wagadzirira kugadzirisa matambudziko ako ekuvhara chisimbiso anonyanya kuoma?
Taura nesu kuti tikurukure nezvechikumbiro chako.Chikwata chedu chehunyanzvi chinogona kupa mazano anoenderana nedata, magadzirirwo akagadzirwa, uye mienzaniso kuti purojekiti yenyu ibudirire.
