Muhupenyu hwezuva nezuva tinogona kuwanzoona ptfe chubhu, saka, ptfe chubhu mukuita kwekugadzirisa isu tinofanirwa kutarisisa kune zvakakosha?
Mukugadzira simbi yakamisikidzwa PTFE pombi, zvinotevera pfungwa dzinoda kutariswa kune:
1. pombi yesimbi isina musono zvichienderana nehukuru chaihwo hwezvinhu, pombi yesimbi uye welding ring welding, mhete inogona kushandisa manual argon arc welding, welding splash nefaira kuchenesa, uye fillet weld mukona yakatenderedzwa, isina inopinza. kumucheto.
2. Dhonza kagomba kumucheto kwepombi yesimbi, nyora zvakajeka, uye usaivhara.Gomba iri rinoshandiswa kuburitsa gasi rasara pakati pepombi yesimbi nepombi yetetrafluoroethylene panguva yekudziya, uye rinoshandiswa kuona kana pombi yetetrafluoroethylene yakakuvara uye yadeuka panguva yekuedzwa kwekumanikidza.
3. pombi yesimbi inofanira kunge yakagara yaunganidzwa isati yaiswa.Iyo yekubatanidza ichaunganidzwa neasbestos goridhe padhi yehukobvu hwakakodzera, kuitira kuti ienderane nehukuru hwese zvinodiwa mushure mekugadzira.
4. pashure gungano musono simbi nyere kuti jecha kuputika kurapwa, kubvisa yomukati rusvingo ngura, uye ipapo nemhepo compressed kuchenesa chubhu mhango.Isa tetrafluoroethylene chubhu muchubhu yesimbi.Kana imwe tetrafluoroethylene pombi isina kutenderera uye isingakwanise kuiswa, mvura inopisa, chiutsi kana yepakati frequency yekupisa choto inofanira kushandiswa kupisa tetrafluoroethylene pombi, tembiricha yekudziya haipfuure 100 ℃.
5. Funga nezvehurefu hweflanging paunenge uchicheka teflon pipe.Kazhinji, 35-40 kureba kwakaiswa parutivi pamusoro peiyo welding mhete pamusoro.Iyo asbestos goridhe gasket inofanira kuiswa paTEflon chubhu isati yaputika.Kupeta teflon chubhu mumatanho maviri, kutanga kupinda mubhero, iyi flanging uchishandisa tapered cast aruminiyamu chimedu.Paunenge uchipisa, kupisa vivipary nemoto we oxyacetylene.Kupisa kwechigadzirwa kunoyerwa ne semiconductor pamusoro thermometer.Tembiricha haifanire kunge yakanyanya kukwirira.Tembiricha inofanira kudzorwa pakati pe260℃ ne280℃.Paunenge uchidzima, zvishoma nezvishoma tsikirira nhumbi yekuberekera yakadziya.Kana bhiza rekuzvara rasvika kumucheto kwemhete yewelding, usadzvanya zvakare.Panguva ino, itonhodze nemvura uye wobvisa nhumbi yekuzvara kana yatonhora kusvika kune tembiricha.Iyo flanging yedanho rechipiri inowedzera plasticizes muromo.Iyi i flat.
6. mushure mekupisa, zvishoma nezvishoma dzvanya pasi uye wonyatsodzvanya flat, uye wozotonhorera nemvura kusvika kune ambient tembiricha, wozobvisa plug.
7. pombi yakamisikidzwa ine ndiro yakanaka yebofu, kupinda muhumburumbira yekudziya yakakosha, yakabatana nechubhu yemhepo yakamanikidzwa, ichidziya silinda nepakati penzira yekudziya, kuitira kuti tembiricha yese yepombi isvike pa280 ℃, uye zvishoma nezvishoma kuburikidza. 8-LOKGF/cm2 compressed mweya.Isa tetrafluoron chubhu mumvura yemvura, nyudza chubhu mumvura, zvishoma nezvishoma upinde mu 15kgf / cm2 mweya wakamanikidzwa, tarisa kana pane mabhubhu pagomba, kana akawanikwa, zvinoratidza kuti tetrafluoron chubhu yakaputsika.Chikonzero chiri kunyanya nekuda kwekudziya kusina kuenzana kana inflation kumhanya zvakanyanya.Iyo pombi yesimbi yakavharwa ichavharwa kumativi ose neplate rehuni kudzivirira kukanganisa kwepombi yetetrafluoron.
