Ukusetshenziswa kwendandatho yokuvalwa kwerabha kungavimbela kahle ukuvuza kwamafutha okugcoba noma ukungena kwezinye izinto, futhi kudlale indima enhle ekuvikeleni okokusebenza.Njengamanje isetshenziswa kabanzi ezimbonini zezokwelapha nezokudla ze-elekthronikhi, kepha ukusetshenziswa okuhlukile kusetshenziswa izigxivizo zenjoloba Izinto zephedi zingahluka, ake sibheke izinto zophawu lwenjoloba.
1. Indandatho yokuvala irabha ye-Fluorine: Inokumelana nezinga lokushisa eliphezulu, ingasetshenziswa endaweni engu--30°C-+250°C, futhi imelana nama-oxidants aqinile, amafutha, ama-asidi nama-alkali.Imvamisa isetshenziswa ekushiseni okuphezulu, i-vacuum ephezulu kanye nemvelo yokucindezela okuphezulu, efanelekile endaweni kawoyela.Ngenxa yezakhiwo ezihlukahlukene ezinhle kakhulu, irabha ye-fluorine isetshenziswa kabanzi ku-petroleum, imboni yamakhemikhali, izindiza, i-aerospace neminye iminyango.
2. I-Silicone rubber gasket: Inokusebenza okuvelele okuphakeme nokuphansi kokumelana nezinga lokushisa, igcina ukunwebeka okuhle ezingeni lokushisa elingu-70°C-+260°C, futhi inezinzuzo zokumelana ne-ozone nokumelana nokuguga kwesimo sezulu, futhi ifaneleka imishini ezishisayo.I-Gasket.
3. I-Nitrile rubber sealing gasket: Inamafutha amahle kakhulu futhi imelana ne-solvent enamakha, kodwa ayimelani nama-ketone, ama-ester, nama-hydrocarbon ane-chlorine.Ngakho-ke, imikhiqizo yokuvala uwoyela ukumelana nowoyela yenziwa ikakhulukazi ngerabha ye-nitrile.
4. I-Neoprene sealing gasket: Inokumelana okuhle kwamafutha, ukumelana ne-solvent, i-chemical medium nezinye izakhiwo, kodwa ayimelani namafutha anuka kamnandi.Ibonakala ngokumelana okuhle kakhulu nokuguga kwesimo sezulu kanye nokuguga kwe-ozone.Ekukhiqizeni, irabha ye-neoprene ivame ukusetshenziselwa ukwenza imichilo yokuvala umnyango nefasitela kanye nama-diaphragm kanye nemikhiqizo yokuvala i-vacuum evamile;
5. Iphedi yenjoloba ye-EPDM: Inokumelana okuhle kwezinga lokushisa, ukumelana nesimo sezulu kanye nokusebenza kokuguga kwe-ozone, futhi ngokuvamile isetshenziswa kabanzi emigqeni yokuvala iminyango namafasitela kanye nasembonini yezimoto.
Yini okufanele inakwe lapho ufaka indandatho ye-rubber seal?
Izindandatho zokuvala zenjoloba zisetshenziswa ezintweni eziningi zemishini.Ezinye izindandatho zokuvala zisetshenziswa ekuhlanganyeleni kwezingxenye ezimbili zemishini.Uma izindandatho zenjoloba zingafakwanga kahle, ngeke zithinte kuphela ukuzinza kwemishini lapho isetshenziswa, kodwa futhi ibangele umonakalo emasongweni enjoloba.umonakalo.Ngakho-ke, ngaphezu kwekhwalithi yendandatho yokuvala irabha, ukufakwa kwayo nakho kubaluleke kakhulu.Ukuze ujulise ukuqonda kwakho, sikulethele ezinye izindlela zokufaka indandatho yokuvala injoloba ukuze uyisebenzise kamuva.
1. Ungafaki endaweni engafanele futhi ulimaze izindebe.Izibazi ezingenhla ezindebeni zingase zibangele ukuvuza okusobala kwamafutha.
2. Vimbela ukufakwa ngempoqo.Ngeke ishaywe ngesando, kodwa ithuluzi elikhethekile kufanele lisetshenziswe ukuze ucindezele indandatho yokuvala ingene emgodini wesihlalo kuqala, bese usebenzisa isilinda esilula ukuvikela udebe ku-spline.Ngaphambi kokufaka, gcoba amafutha ezindebeni ukuze ukufakwa nokuvimbela ukusebenza kokuqala, qaphela ukuhlanza.
3. Vimbela ukusetshenziswa okudlulelwe yisikhathi.Impilo yesevisi yephedi yenjoloba eguquguqukayo ngokuvamile ingu-5000h, futhi indandatho yophawu kufanele ishintshwe ngesikhathi.
4. Gwema ukusebenzisa izindandatho ezindala zokuvala.Uma usebenzisa indandatho entsha yokuvala, hlola ngokucophelela ikhwalithi yayo yendawo, qiniseka ukuthi azikho izimbobo ezincane, ama-protrusions, imifantu kanye nama-grooves, njll, futhi ube nokunwebeka okwanele ngaphambi kokusetshenziswa.
4. Ukuze kuvinjwe ukuvuza kwamafutha ngenxa yokulimala, kufanele kusetshenziswe ngokuvumelana nemithethonqubo.Ngesikhathi esifanayo, umshini awukwazi ukulayishwa ngokweqile isikhathi eside noma ubekwe endaweni enzima kakhulu.
