Vagadziri vazhinji verabha re nitrile butadiene (NBR) vane matambudziko ekubvisa tsvina inonaka. Kucheka zvishoma nezvishoma nemaoko hakukwanirise zvinodiwa pakugadzira, uye maburrs madiki ari pazvikamu zvakanyatsonaka haagone kubviswa zvakakwana, izvo zvave dambudziko guru rinodzivisa purofiti yehurongwa. STMC (Nanjing Zhaoling Precision) yave ichinyanya kutarisa pakubvisa tsvina inonaka kwemakumi emakore. Tekinoroji yayo yekubvisa tsvina inonaka ye liquid nitrogen cryogenic inogadzirisa zvinobudirira marwadzo emaindasitiri nekushanda zvakanyanya uye kunyatsoita zvinhu nemazvo, zvichibatsira vagadziri vazhinji verabha kugadzirisa matambudziko ekubvisa tsvina zvachose.
Nei Mafekitori eNBR Aine Dambudziko Nekuda Kwekubvisa Mvura Munzvimbo Yayo
NBR ine kuchinjika kwakanyanya uye kusimba, zvichikonzera kuti pave nemaburi akasimba pamitsetse yekuparadzanisa, maburi epinhole uye maburi. Nzira dzemazuva ano dzekudzima maburi dzine matambudziko ari pachena: Panyaya yekushanda zvakanaka kwekugadzira, kuchekerera nemaoko kunoda basa guru rine muganho wezuva nezuva, zvichikonzera kunonoka kwekutumira zvinhu zvakawanda. Kuchekerera nebanga remuchina kunokonzeresa kunamatira kwezvinhu uye kuvharika kwemuchina; maburi akavanzika anoda kugadziriswa kwechipiri uye kuwedzera nguva yekugadzira. Nezvekunyatsogadzirisa, simba rekucheka nemaoko risingawirirane rinowanzo kukonzera kurambwa kwezvigadzirwa kubva kumaburi anocheka zvakanyanya kana asara. Kupisa kwakanyanya kunokonzerwa nekupolisha kunokuvadza kushanda kweseal kwezvikamu zveNBR nekubudirira kwekugadzirwa kwechigadzirwa, zvichikundikana mitemo yakasimba yekuongorora mhando yechikamu chekugadzirisa mota.
Kubvisa Nitrogen Yemvura Yakasviba: Mhinduro Yekubvisa NBR Yakanyanya Kushanda Uye Yakanyatsonaka
Zvichibva padanho rekupisa kwakaderera kwazvo re -196°C liquid nitrogen, cryogenic deflashing inobvisa maburrs kuburikidza ne cold embrittlement. Inoshandisa zvizere nguva dzakasiyana dze cold embrittlement pakati pe bulk NBR substrate uye thin flash nekuda kwekusiyana kweukobvu kuti iite dampling isina kukuvara uye ichishandura nzira dzechinyakare dze deflashing: Mabasa anovharwa mukati memukamuri yemidziyo uye anotonhodzwa nekukurumidza kusvika -80℃ ~ -140℃ ne liquid nitrogen. Ultra-thin flash inotangira pa 0.01mm kusvika 0.2mm inoshanduka kuita brittle pasi pekupisa kwakaderera nepo gobvu NBR base richichengetedza elasticity yepakutanga uye physical properties. Nyoni dzakagadzirwa zvakananga dzinobva dzaputirwa nekukurumidza kuti dzipwanye uye dzibvise brittle flash. Marara e burr anounganidzwa pakati kuburikidza ne negative-pressure filtering system pasina kukwenya kana kukuvadza zvikamu zvemuviri.
Kubudirira Kwakawedzerwa Kwekugadzira
1. Kugadziriswa kwebhatani otomatiki:
STMC yakagadzira yega michina yeJishe series cryogenic deflashing inogadzira zvigadzirwa zveNBR zve20~50kg pabhechi mukati memaminitsi 10~15. Muchina mumwe chete wakaenzana nekugadzirwa kwevashandi vane hunyanzvi hwemaoko 6~12. Vashandi vanogona kutarisira mayuniti maviri kusvika matatu kuburikidza nekutonga kwePLC otomatiki, vachideredza mari yevashandi neanopfuura 70%.
2. Kuenderana kwakazara nekushandazve kwe zero:
Midziyo iyi inobvisa zvakakwana maburi akavanzwa mukati memakomba, maburi eO-rings, maburi emafuta ane chimiro chakasarudzika uye zvikamu zveNBR zvakatetepa panguva imwe chete, zvichibvisa kuchekererwa kwemaoko. Kubudirira mushure mekugadzirisa kunokwira ka3-5 kuti kubatsire maodha akawanda kubva kuvatengi vemotokari nevekunze kwenyika.
3. Marongerwo ekuchengetedza nzvimbo:
Muchina wega wega unogara pasi pemamita gumi emasekonzi, uchitsiva makumi emamita emasekonzi emasaiti ekugadzira nemaoko uye uchisunungura nzvimbo yekushandira kuti pave nekuwedzera kugona kwekugadzira vulcanization.
Machining Akanyatsorongeka Akakodzera
1. Kururama kwekucheka kwe micron-level:
Kudzora tembiricha kwakanyatsonaka kunovhara tembiricha yeNBR kuti ibvise flash diki kusvika pa 0.01mm. Kushivirira kwechinhu chakagadzirwa kunodzorwa mukati me 0.03mm pasina maburi akasara kana kukuvara kwakanyanya. Goho rechinhu rinokwira kubva pa 75% pasi pekugadzirisa kwakajairika kusvika pamusoro pe 99.2%, zvichitevedzera zvinodiwa zvemaindasitiri emagetsi matsva uye ekugadzirisa otomatiki.
2. Hunhu hwebhechi rinowirirana:
Maparamita emidziyo yakachengetedzwa anovimbisa kugadziriswa kwakafananar zvigadzirwa zveNBR zvakafanana, zvichibvisa kusagadzikana kunokonzerwa nekushanda nemaoko uye kuve nechokwadi chekuti chitarisiko chakafanana uye saizi pakati pemabheti ese kuti zvipfuure kuongororwa kwemhando yepamusoro kwevatengi vari pasi pemvura.
3. Kushanda kwerabha kwepakutanga kwakachengetedzwa:
Hapana kupisa kunokonzereswa nekukweshana kunogadzirwa mukugadzirisa tembiricha yakaderera, zvichidzivirira kusimba kweNBR uye kuramba mafuta pasina kukwegura, nokudaro zvichichengetedza hupenyu hwebasa rekuvhara kwenguva refu hwezvinhu zvapera.
STMC: Nyanzvi yemakore makumi maviri muCryogenic Deflashing yakagadzirirwa NBR
STMC inozvipira kuR&D yemidziyo yekubvisa nitrogen yemvura uye inogadzira michina yakagadzirwa nenzira yakakodzera uye matekiniki anoenderana nehunhu hwezvinhu zveNBR zvezvisimbiso zvemafuta, maO-rings uye zvikamu zverabha zvisina kujairika. Kuyedzwa kwemuenzaniso wemahara kunowanikwa, pamwe chete nemasevhisi e-full-spectrum anosanganisira nhungamiro yekusarudza michina, kuraira panzvimbo uye rutsigiro rwenguva dzese mushure mekutengesa. Michina yakavharwa zvizere inozadzisa mwero wekuongorora zvakatipoteredza. Kambani iyi yakabatsira vagadziri verabha munyika yese mukushandura tekinoroji kwemaitiro ekubvisa nitrogen kuti vaderedze mitengo yakakwira yekugadzirisa uye kusimudzira mhando yechigadzirwa zvakanyanya.
Ruzivo rwekuonana kuti uwane mukana wekuchengetedza sampuli yemahara uye kubvunza zvakadzama
