Ungakhetha kanjani indandatho yokuvala yesistimu ye-hydraulic?
1. I-NBR nitrile rubber sealing ring ifaneleka ukusetshenziswa ku-petroleum hydraulic oil, i-ethylene glycol hydraulic oil, i-diester lubricating oil, i-petroli, amanzi, i-silicone grease, i-silicone yamafutha kanye neminye imidiya. Iwuphawu lwerabha olusetshenziswa kakhulu futhi olubiza kancane. Ayifanele ukusetshenziswa kuzincibilikisi ze-polar ezifana ne-ketone, i-ozone, i-nitrohydrocarbons, i-MEK ne-chloroform. Izinga lokushisa elijwayelekile lokusetshenziswa ngu -40 ~ 120 ℃. Okwesibili, i-HNBR hydrogenated nitrile sealing sealing ring inokumelana nokugqwala okuhle kakhulu, ukumelana nezinyembezi nezici zokuwohloka kokucindezela, ukumelana ne-ozone, ukumelana nokukhanya kwelanga, ukumelana nesimo sezulu kuhle. Ukumelana nokugqoka okungcono kunerabha ye-nitrile. Ifanele imishini yokuwasha, amasistimu enjini yezimoto kanye nesistimu yesiqandisi esebenzisa isiqandisi esisha esihambisana nemvelo esingu-R134a. Akunconyelwe ukusetshenziswa kotshwala, ama-ester, noma izixazululo ezinamakha. Izinga lokushisa elijwayelekile lokusetshenziswa lingu-40~150 ℃. Okwesithathu, i-FLS fluorine abicah silicone sealing ring inezinzuzo zerabha ye-fluorine nerabha ye-silicone, ukumelana nowoyela, ukumelana ne-solvent, ukumelana nowoyela kaphethiloli kanye nokumelana nokushisa okuphezulu nokuphansi kuhle. Iyakwazi ukumelana nokuhlaselwa komoyampilo oqukethe izinhlanganisela, i-hydrocarbon enamakha enezinyibilikisi ne-chlorine equkethe izinyibilikisi. Ngokuvamile isetshenziselwa izindiza, indiza kanye nezinjongo zempi. Ukuchayeka kuma-ketone kanye noketshezi lwamabhuleki akunconywa. Izinga lokushisa elijwayelekile lokusetshenziswa ngu -50 ~ 200 ℃.
2, ngaphezu kwezidingo ezijwayelekile zendandatho yokuvala, indandatho yokubeka uphawu kufanele futhi inake lezi zimo ezilandelayo: (1) ukunwebeka nokuqinile; (2) Amandla afanele emishini, okuhlanganisa amandla okunweba, ubude namandla okudabula. (3) Ukusebenza kuzinzile, akulula ukuvuvukala phakathi nendawo, futhi umphumela wokunciphisa ukushisa (umphumela we-Joule) mncane. (4) Kulula ukucubungula nokuma, futhi ingagcina usayizi oqondile. (5) ayigqwali indawo yokuxhumana, ayingcolisi into ephakathi nendawo, njll. Into efanelekile nesetshenziswa kakhulu ukuhlangabezana nezimfuneko ezingenhla irabha, ngakho indandatho yokuvala ngokuvamile yenziwe ngezinto zenjoloba. Kunezinhlobo eziningi zenjoloba, futhi kukhona njalo izinhlobo zenjoloba ezintsha, ukuklama nokukhetha, kufanele kuqonde izici zenjoloba ehlukahlukene, ukukhetha okunengqondo.
3. Izinzuzo
(1) Indandatho yokuvala kufanele ibe nokusebenza okuhle kokuvala ingcindezi yokusebenza kanye nebanga elithile lokushisa, futhi ingathuthukisa ngokuzenzakalelayo ukusebenza kokuvala ngokunyuka kwengcindezi.
(2) Ukungqubuzana phakathi kwensimbi yokuvala kanye nezingxenye ezihambayo kufanele kube kuncane, futhi i-coefficient yokungqubuzana kufanele izinze.
(3) Indandatho yokuvala inokumelana nokugqwala okuqinile, akulula ukuguga, inempilo ende yokusebenza, ukumelana nokugqokwa okuhle, futhi inganxeshezelwa ngokuzenzakalelayo ngemva kokuguga ngezinga elithile.
(4) Isakhiwo esilula, kulula ukusisebenzisa futhi sigcineke, ukuze indandatho yokuvala ibe nempilo ende. Ukulimala kwendandatho ye-seal kuzodala ukuvuza, okuholela ekumoshweni kwemithombo yezindaba esebenzayo, ukungcoliswa komshini nendawo ezungezile, futhi kubangele nokuhluleka kokusebenza kwemishini kanye nezingozi zomuntu siqu. Ukuvuza kwangaphakathi kuzobangela ukusebenza kahle kwe-volumetric yesistimu ye-hydraulic yehle kakhulu, futhi ingcindezi yokusebenza edingekayo ayikwazi ukufinyelelwa, noma ngisho nomsebenzi awukwazi ukwenziwa. Izinhlayiya zothuli ezincane ezihlasela isistimu zingabangela noma zengeze ukuguga kwamapheya okushayisana kwezingxenye ze-hydraulic, kuqhubeke kuholele ekuvuzeni. Ngakho-ke, ama-seal kanye nemishini yokuvala iyingxenye ebalulekile yemishini ye-hydraulic. Ukuthembeka nempilo yesevisi yomsebenzi wayo kuyinkomba ebalulekile yokukala ikhwalithi yesistimu ye-hydraulic.
UZhuo Meng Shanghai Auto Co., Ltd. uzibophezele ekuthengiseni izingxenye zezimoto ze-MG&MAUXS wamukelekile ukuzithenga.
