Tšebelisong ea li-O-rings, maemo a khethehileng a ts'ebetso le maemo a ts'ebeliso a tlameha ho nahanoa.Mocheso le khatello li tla ba le liphello le tahlehelo ho O-ring seal.Ka hona, lintlha tse 5 tse latelang li lokela ho nahanoa ts'ebelisong ea litiiso tsa rabara tsa O-ring:
1. Maemo a ho sebetsa le maemo a ho sebetsa;
2. Ho lumellana ha sehlahisoa le mochine o sebetsang, 'me joale ho nahanoa ka khatello, mocheso, nako e tsoelang pele ea ho sebetsa, potoloho ea ts'ebetso le maemo a mang a tiiso, le ho phahama ha mocheso ho bakoang ke mocheso oa likhohlano ho boetse ho lokela ho nkoa ka linako tse potolohang;
3. Foromo ea tiiso: Ha tiiso ea shaft e kenngoa ka radially, ho kheloha pakeng tsa bophara bo ka hare ba O-ring le bophara bo lokelang ho tiisoa e lokela ho ba nyenyane kamoo ho ka khonehang;bakeng sa tiiso ea lesoba, bophara bo ka hare bo lokela ho lekana kapa bo nyenyane ho feta bophara ba groove.Ha u kenya axially, tataiso ea khatello e boetse e lokela ho nkoa.Ha khatello ea ka hare e sebelisoa, bophara ba ka ntle ba O-ring e lokela ho ba hoo e ka bang 1% ~ 2% e kholo ho feta bophara bo ka ntle ba groove.Ha bophara bo ka ntle bo le tlas'a khatello, bophara bo ka hare ba O-ring e lokela ho ba bonyane ho feta groove1% ~ 3%.
4. Lintlha tse ling tse amang ts'ebetso ea ho tiisa
1) Ho thatafala: Etsa qeto ea palo ea compression ea O-ring le lekhalo le phahameng le lumelletsoeng la extrusion ea groove;
2) Lekhalo la Extrusion: khatello ea tsamaiso, bophara ba karolo ea O-ring le boima ba thepa bo amana.
3) Compression deformation e sa feleng: Tabeng ea khatello, e le ho thibela deformation ea polasetiki e sa feleng.Khatello e phahameng ka ho fetisisa e lumelletsoeng ke O-ring e ka bang 30% ho litiiso tse tsitsitseng le tse ka bang 20% ho litiiso tse matla.
4) Chelete ea pele ho compression: E le ho etsa bonnete ba ho tiea ka har'a groove ea O-ring, palo ea pele ea khatello e lokela ho bolokoa.Chelete ea pele ho compression e amanang le bophara ba karolo hangata e ka ba 15% ~ 30% ho tiiso e tsitsitseng.E ka ba 9% ~ 25% ho tiiso e matla.
5) Khatello le khatello: Bakeng sa tiiso ea lesoba, O-ring e boemong bo otlolohileng, 'me tekanyo e phahameng e amohelehang ke 6%.Bakeng sa tiiso ea shaft, O-ring e hatelloa ho latela tataiso ea selikalikoe, 'me khatello e phahameng e lumelletsoeng ea circumference ke 3%.
5. O-ring e sebelisetsoa ho tsamaea ka lebelo le tlaase la rotary le tiiso ea rotary shaft e nang le potoloho e khutšoanyane ea ts'ebetso.Ha lebelo la peripheral le le tlase ho 0.5m / s, khetho ea O-ring e ka thehoa ho latela maemo a tloaelehileng a moralo;ha lebelo la peripheral le le leholo ho feta 0.5m / s, Hoa hlokahala ho nahana ka ketsahalo ea hore selikalikoe se selelele sa rabara se fokotseha ka mor'a ho futhumala, 'me lesale la ho tiisa le lokela ho khethoa e le hore bophara bo ka hare bo ka ba 2% ho feta bophara ba molamu o tiisitsoeng.
