Ungakuthuthukisa kanjani ukusebenza kwezimpawu zenjoloba?

Ukuqalisa

Izimpawu zenjoloba zidlala indima ebalulekile kuzinhlelo zokusebenza eziningi zezimboni, kuqinisekisa ubuqotho kanye nokwenza imisebenzi ngokuvimbela ukuvuza nokungcola. Lezi zimpawu zibaluleke kakhulu ezimotweni, ze-aerospace, kanye nezimboni zokukhiqiza, phakathi kwabanye. Kodwa-ke, ukufeza ukusebenza kahle kwezimpawu zenjoloba kudinga ukuqonda okujulile kwezinto zazo ezibonakalayo, ukucatshangelwa kwedizayini, kanye nezici zezemvelo. Kulesi sihloko, sizohlola amasu asemqoka ukuthuthukisa ukusebenza kwezimpawu zenjoloba, ukuwakhipha ekukhetheni kwezinto ezibonakalayo, izinqubo zokukhiqiza, nezindlela zokugcina. Kulabo abanentshisekelo ekusetshenzisweni okuhlukahlukene kwe Izimpawu zenjoloba , isihloko sifinyelela ezindaweni eziningi ezikhethekile.

Ukuqonda izinto zensimbi zenjoloba

Izakhiwo ezibonakalayo kanye nomthelela wazo

Ukusebenza kwezimpawu zenjoloba kuthonywa kakhulu ukwakheka kwezinto ezibonakalayo. Izinto ezijwayelekile zifaka i-nitrile rubber (i-NBR), i-ethbry propylene diene monomer (i-EPDM), nama-fluoroolastomers (FKM). Indwangu ngayinye inezakhiwo ezihlukile ezinquma ukufaneleka kwayo kwezicelo ezithile. Isibonelo, i-NBR yaziwa ngokumelana kwayo okuhle kwamafutha, okwenza ilungele izinhlelo zokusebenza zezimoto kanye ne-hydraulic. Ngakolunye uhlangothi, ama-EPDM ama-Excels esimweni sezulu nase-Ozone ukumelana, okwenza kube yikhethelo elikhethwayo lezicelo zangaphandle. Ama-Fluoloelastomers, ngokushisa kwawo okuhlukile kanye nokumelana kwamakhemikhali, asetshenziswa kabanzi kwizimboni ze-aerospace kanye namakhemikhali.

Ukuqanjwa Kwezinto Ezingaphezulu Kwezinto

Intuthuko yakamuva ku-Material Science iholele ekuthuthukisweni kwe-hybrid kanye nezinto zokwakha zenjoloba ezihlanganisiwe. Lezi zinto zokwenziwa zihlanganisa amandla ama-polymers amaningi ukufeza ukusebenza okuphezulu. Isibonelo, i-nitrile buthadineuteen rubber (HNBREEN (HNBR) inikeza ukushisa okuthuthukile kanye nokumelana kwamakhemikhali kuqhathaniswa ne-NBR yendabuko. Ngokufanayo, ukuhlanganiswa kwe-EPDM namanye ama-elastomers kungathuthukisa ukuguquguquka nokuqina. Ukuqonda lokhu okusha kubalulekile ekukhetheni okulungile kwezicelo eziphezulu zokusebenza.

Design ukucatshangelwa kwezimpawu zenjoloba

Ukulungiselela i-geometry seal

Ijometri yophawu lwenjoloba luthinta kakhulu ukusebenza kwalo. Izici ezinjengesomo lesigaba sesigaba, usayizi, kanye nokuqedwa komhlaba kumele kubhekwe ngokucophelela ngesikhathi sesigaba sokuklama. Isibonelo, ama-O-Rings asetshenziselwa izinhlelo ze-static seating ngenxa yokwakheka kwawo okulula kanye nokufakwa kalula. Kodwa-ke, ngezinhlelo zokusebenza ezinamandla, amadizayini akhethekile anjengezinkomishi ze-U noma ama-V-Rings angasebenza kakhulu ekutholeni ukwahlukahluka kokuhamba nokucindezela.

Ukusatshalaliswa kwengcindezi nokuphathwa kwemithwalo

Ukusatshalaliswa kwengcindezi efanelekile kubalulekile ukuvikela ukwehluleka ngaphambi kwesikhathi kwezimpawu zenjoloba. Ukucindezelwa okungalingani kungaholela ekugqokeni nasekuhlisweni kwale ndawo, kunciphisa isikhathi sokuphila kukaphawu. Ukuhlaziywa kwe-Emetion (FEA) Ithuluzi elinamandla lokulingisa ukusatshalaliswa kwengcindezelo kanye nokwandisa ukwakhiwa kwesikrini. Ngokuhlaziya izici ezinjengesethi yokucindezela, ukugcwala, kanye namandla ashubile, onjiniyela bangakwazi ukuklama izikhala ezimelana nengcindezi yokusebenza ngempumelelo.

Izinqubo zokukhiqiza kanye nokulawulwa kwekhwalithi

Amasu okubumbana ngokunemba

Inqubo yokukhiqiza idlala indima ebaluleke kakhulu ekunqumeni ikhwalithi nokusebenza kwezimpawu zenjoloba. Amasu wokubumba ngokunemba, njengokubumba okuhlanganisiwe nokubumba kokucindezela, qiniseka ubukhulu obungaguquguquki kanye nokuqedwa komhlaba. Lezi zinqubo ziphinde zinciphise iziphambeko ezinjenge-voids ne-flash, ezingabeka uphawu lobuqotho. Ubuchwepheshe obuthuthukisiwe bokubumba, kufaka phakathi ukubumba kwe-liquid abicone Rubber (LSR), banikele ngezinzuzo ezengeziwe ezinjengezikhathi zomjikelezo ngokushesha kanye nezinto ezibonakalayo ezithuthukisiwe.

Ukuqinisekiswa kwekhwalithi nokuhlola

Izindlela zokulawula ezisezingeni elifanele zibalulekile ukuze ziqinisekise ukuthi izimpawu zenjoloba zihlangabezana namazinga okusebenza. Izindlela zokuhlola ezinjengokuhlola kanzima, ukuhlolwa okuthe xaxa, nokuhlolwa kokuguga kunikeza ukuqonda okubalulekile ezintweni ezibonakalayo kanye nokuqina. Ngezicelo ezibucayi, izivivinyo ezengeziwe ezinjengokuphikiswa kwamakhemikhali kanye nokuhamba ngebhayisikoshi okushisayo kungadingeka. Ukuqalisa amaphrothokholi wokuqinisekiswa kwekhwalithi eqinile kusiza ekuboneni nasekubhekaneni nezinkinga ezingaba khona ngaphambi kokuthunyelwa kwezimpawu emkhakheni.

Ukulungiswa nokuphila isikhathi eside

Imikhuba yokugcina yokuvimbela

Ukulungiswa njalo kubalulekile ukwelula isikhathi sokuphila kwezimpawu zenjoloba. Lokhu kufaka phakathi izimpawu zokuhlola izimpawu zokugqoka, njengokuqhekeka, ama-deformation, noma ukuguquguquka. I-Lubrication ingasiza futhi ukunciphisa ukungqubuzana nokugqoka ezinhlelweni ezinamandla. Ngokwengeziwe, ukufaka esikhundleni kwezimpawu ngezikhathi ezithile ngezikhathi ezithile kuvimbela ukwehluleka okungalindelekile futhi kuqinisekise ukusebenza okungaguquki.

Ukucatshangelwa Kwezemvelo

Izici zezemvelo ezifana nokushisa, umswakama, nokuchayeka kumakhemikhali kungathinta kakhulu ukusebenza kwezimpawu zenjoloba. Ukukhetha izinto zokwenziwa ngezakhiwo ezifanele zokumelana kanye nokusebenzisa izindlela zokuvikela, ezinjengezimbali noma izithiyo, zinganciphisa le miphumela. Isibonelo, izimpawu ezisetshenziswa kuzinhlelo zokusebenza zangaphandle zingazuza ngezinto ezivimbela ukumelana ne-UV ukuvikela ukonakala kusuka ekubonisweni kwelanga.

Ukugcina

Ukuthuthukisa ukusebenza kwezimpawu zenjoloba kudinga indlela ebanzi ehlanganisa ukukhethwa kwezinto ezibonakalayo, ukwakhiwa kwedizayini, ukukhiqiza ubuhle, kanye nokugcinwa okuhle. Ngokuqonda ukuxhumeka kwalezi zinto, izimboni zingafinyelela izixazululo ezithembekile nezihlala isikhathi eside. Ukuthola eminye imininingwane kuzicelo kanye nezinto ezintsha I-Rubber Seals , ukuhlola intuthuko yakamuva yezimboni kunconywa kakhulu.
