Gupakira ibishushanyo, nkibikoresho byo hejuru - bifunga imikorere, bikoreshwa cyane mu nganda zikora imiti, peteroli, ingufu, n’imashini. Ubwiza bwayo buhebuje - ubushyuhe no kurwanya ruswa, kimwe n’imiterere yacyo - amavuta yo kwisiga, bituma iba ikintu cyingenzi muri sisitemu yo gufunga inganda. Ariko, gukoresha nabi birashobora gutera kunanirwa kashe, kumeneka, ndetse no kwangiza ibikoresho. Kubwibyo, kumenya neza uburyo bukoreshwa bwo gupakira grafite ni ngombwa.
1. Guhitamo no Kwitegura Gupakira Graphite
Mugihe uhisemo gupakira grafite, ni ngombwa kumenya ubwoko bukwiye bushingiye kumikorere yihariye (nkubushyuhe, umuvuduko, hamwe nibitangazamakuru byangirika). Ubwoko busanzwe bwo gupakira burimo grafite yagutse hamwe na grafite yatewe (nka yatewe na resin, ibyuma, cyangwa polytetrafluoroethylene). Kubushyuhe bwo hejuru - nubushyuhe bwo hejuru - ibidukikije byumuvuduko, hejuru - ubuziranenge bwagutse bwa grafite cyangwa ibyuma - byatewe na grafite irasabwa kongera imbaraga za mashini no gutembera.
Gupakira ibishushanyo bigomba gutegurwa neza mbere yo kubikoresha. Ubwa mbere, genzura ubunyangamugayo bwo gupakira kugirango umenye ko butarangiritse cyangwa umwanda. Icya kabiri, niba gupakira biri muruzingo cyangwa guhagarika, bigomba gukatirwa kugeza kuburebure bukwiye hashingiwe ku bipimo by'urwobo rufunze, byemeza ko impande zaciwe zoroshye kugira ngo hirindwe ibisebe bishobora kugira ingaruka ku kashe. Kubipfunyika bya grafite byatewe, menya neza ko urwego rwatewe rudakonje cyangwa ngo rwangiritse. Nibiba ngombwa, gusya byoroheje birashobora gukorwa kugirango uburinganire burangire.
2. Gupakira tekinike no kugenzura kwikuramo
Uburyo bwo gupakira ibishushanyo mbonera bigira ingaruka kumikorere. Mugihe cyo gupakira, ihame rya "guhuza ibice" rigomba gukurikizwa, ryuzuza icyuho gifunga uruziga icyarimwe. Menya neza ko impande zaciwe za buri ruziga zitondekanye kuri dogere 90 -120 kugirango zibe inzitizi ikomeza. Birasabwa gukoresha igikoresho cyabugenewe cyo gupakira cyangwa igikoresho cyo gukanda kugirango wirinde kwikuramo intoki mu buryo butaziguye, bishobora gutera impinduka zidahuye.
Kwiyunvikana nikintu gikomeye cyo gupakira grafite. Kwiyunvikana gukabije birashobora gutuma gupakira bikomera, ubwiyongere bukabije, ndetse bikangiza no gufunga hejuru; kwikuramo bidahagije birashobora gutera byoroshye kumeneka. Mubisanzwe, compression yambere yo gupakira igomba kugenzurwa kuri 15% -30% yumurongo wa axial, kandi gupakira bigomba guhinduka buhoro buhoro kurwego rwiza ukoresheje gland. Mu kashe ifite imbaraga (nk'iziri ku kizunguruka cyangwa inkoni zisubirana), komeza gland inshuro nyinshi. Nyuma yo gukomera, koresha ibikoresho hanyuma urebe ko byasohotse kugeza kashe ihamye.
3. Gukora, Kubungabunga, no Gukemura Ibibazo
Gupakira ibishushanyo bishobora gutemba gake mugihe cyambere cyo gukora. Nibisanzwe kandi mubisanzwe birashobora kuvaho mugukomeza gahoro gahoro. Ariko, niba kumeneka bikomeje cyangwa bikabije, hagomba gukorwa iperereza ku bibazo bikurikira:
1.Glande irenze cyangwa yiyemeje: Koresha umurongo wa torque kugirango uhindure imbaraga zo gukomera kugirango wirinde guhangayikishwa cyane.
2.Gupakira kwambara cyangwa gusaza: Nyuma yigihe kirekire - ikora, gupakira grafite birashobora kunanirwa kubera guterana cyangwa kwangirika kwimiti kandi bisaba gusimburwa buri gihe.
3.Ihuza rya Mediya: Niba uburyo bwo gufunga burimo ibice bikomeye (nka slurry cyangwa umucanga), birasabwa gukoresha fibre ya karubone - ishimangira grafite cyangwa igapakira hamwe hamwe n'amavuta yongeweho.
Mugihe cyo kubungabunga buri gihe, genzura buri gihe sisitemu yo gufunga ubushyuhe, kunyeganyega, no kumeneka. Niba agasanduku kuzuza gasanze gashyuha cyane (mubisanzwe biterwa no guterana gukabije), hashobora gukoreshwa ingamba zo gusiga amavuta (nko gutera amavuta make ya silicone) cyangwa gukoresha PTFE - yapakiye grafitike yatewe kugirango ugabanye coefficient de frais.
4. Ibyifuzo byo gusaba kubintu bidasanzwe bikora
Gupakira ibishushanyo bisaba ubundi buryo bwo kwirinda iyo bikoreshejwe mubikorwa bikabije (nka ultra - ubushyuhe bwinshi, ibidukikije byangirika cyane, cyangwa imirasire ya kirimbuzi):
•Ultra-high temperature environments (>Impamyabumenyi 600): Koresha hejuru - ubuziranenge bwaguye grafite cyangwa icyuma gikomatanya - gupakira, kandi ushizemo uburyo bukonje.
• Kubitangazamakuru byangirika cyane (nka acide ikomeye na base): Gupakira ibishushanyo byatewe na PTFE cyangwa ceramic ceramic byatoranijwe kugirango birusheho kurwanya imiti.
•For high-pressure sealing (>30.
Umwanzuro
Gupakira ibishushanyo bifite ibyiza byingenzi byo gukora, ariko imikorere yabyo biterwa cyane nigikorwa gikwiye no kubungabunga. Binyuze mu guhitamo siyanse, kuzuza bisanzwe, kwikuramo neza, no kubungabunga buri gihe, ubuzima bwa kashe burashobora kwaguka cyane kandi imikorere yibikoresho irashobora kuboneka neza. Mubikorwa bifatika, birasabwa guhuza imiterere yihariye yakazi no kugisha inama abatanga ibikoresho cyangwa impuguke za kashe mugihe bibaye ngombwa kugirango hongerwe imikoreshereze yububiko bwa grafite.
