O-ring specification kam rau ua thiab compression

Ua tib zoo saib xyuas qhov ua siab ntev ntawm O-ring cov yam ntxwv. Muaj ob yam ntawm cov kev zam dav dav, ib qho yog sab hauv txoj kab mob siab thiab lwm yam yog xaim diam kam rau. Lub siab kam cuam tshuam nrog qhov loj ntawm cov khoom. Qhov me dua qhov loj me, qhov me dua ntawm lub siab ntev.

Tom qab ntawd, peb kuj yuav tsum tau them sai sai rau qhov compression nqi ntawm O-ring. Lub nyiaj zaws ntawm O-ring yog qhov ntsuas me me. Thaum nws tsis xaiv zoo, nws yuav ua rau tsis muaj qhov tsis sib khi lossis nruj dhau thaum siv.

Yuav ua li cas xaiv cov nqi tsim nyog compression? Tus nqi zaws muaj feem xyuam zoo rau cov khoom siv thiab tawv ntawm O-ring. Piv txwv, yog tias qhov nyuaj ntawm O-ring yog 70 degrees, ces tus nqi compression yog 20%. Feem ntau, qhov ntau dua qhov nyuaj, qhov ntau dua qhov compression, tus nqi compression nyob ntawm daim ntawv thov.
