Muaj ntau yam uas cuam tshuam rau kev sib khi ntawm O-rings. Ntawm lawv, lub siab yog qhov tseem ceeb cuam tshuam rau qhov zoo ntawm cov ntsaws ruaj ruaj. Cov qib siab thiab qhov ntev ntawm lub voj voog hloov pauv muaj qhov cuam tshuam zoo rau kev puas tsuaj rau lub foob (xws li extrusion). Kev cuam tshuam. Qhov siab dua, qhov cuam tshuam ntau dua ntawm lwm yam ntawm kev ua haujlwm ntawm lub foob, xws li kub, ceev, cov khoom siv foob, tshem tawm ntawm lub piston thiab lub tog raj kheej, thiab tshem tawm ntawm lub piston thiab lub tog raj kheej taub hau.
Kuj tseem muaj qhov kub thiab kev sib txhuam. Nws yog ib qho nyuaj rau piav qhia txog qhov siab tshaj plaws siv kub thiab qhov tsawg kawg nkaus siv qhov kub ntawm cov khoom siv foob, vim tias nws yog qhov tshwm sim ntawm kev sib xyaw ua ke ntawm ntau yam. Rau qhov sib txawv ua haujlwm kub ntawm lub piston thiab lub piston pas nrig, lawv yuav tsum tau xaiv txawv. Lwm qhov yog qhov roughness ntawm cov khoom foob, cov yam ntxwv ntawm qhov chaw, qhov siab, qhov nruab nrab, qhov kub thiab txias, cov khoom ntawm lub foob, hom foob thiab qhov ceev ntawm kev txav, uas yog txhua yam uas cuam tshuam rau O - nplhaib. Kev paub dhau los tau pom tias qhov cuam tshuam ntawm cov khoom tuaj txawv teb chaws thiab txawv teb chaws O-rings Cov yam ntxwv ntawm lub tog raj kheej piston thiab qhov chaw ntawm lub piston pas nrig muaj kev cuam tshuam zoo rau lub neej ntawm lub foob. Cov no yog cov yam ntxwv uas cuam tshuam rau kev sib khi ntawm O-rings.
Muaj ntau qhov laj thawj rau kev puas tsuaj, qhov tseem ceeb tshaj plaws yog vim qhov tsis sib xws ntawm lub piston, piston pas nrig thiab lub tog raj kheej, ntau dhau eccentricity, txoj kab uas hla ntawm O-ring seem, thiab lwm yam. O-ring hauv ib lub lis piam. Lub zog tsis sib xws, qee qhov ntawm O-ring rub ntau dhau thiab twist. Feem ntau, O-rings nrog me me cross-sectional qhov ntev yuav ua rau muaj kev sib txhuam tsis sib xws. ua rau distortion. Tsis tas li ntawd, vim yog qhov sib txawv ntawm qhov sib txawv ntawm qhov sib khi, qhov siab tsis sib luag thiab qhov tsis sib xws ntawm O-ring seem, nws yuav ua rau ib feem ntawm O-ring tau compressed ntau dhau, thaum lwm qhov yog dhau lawm. me me los yog tsis compressed. Thaum lub zawj yog eccentric, uas yog, lub coaxial sib txawv yog ntau tshaj qhov compression ntawm O-ring, lub foob yuav ua tsis tiav.
Kev soj ntsuam ntawm qhov laj thawj ntawm qhov tsis sib xws ntawm kev sib khi O-ring Lwm qhov tsis zoo ntawm qhov sib txawv loj ntawm qhov zawj coaxiality yog qhov tsis sib xws ntawm O-nplhaib raws qhov ncig. Tsis tas li ntawd, vim qhov tsis sib xws ntawm O-ring ntu txoj kab uas hla, cov khoom siv hardness, lubricating roj zaj duab xis thickness, thiab lwm yam, nrog rau qhov roughness ntawm lub sealing ncej, ib feem ntawm O-ring slides raws qhov chaw ua haujlwm, thaum lwm qhov dov, ua rau Twisted O-rings. Nws yog ib qho txaus ntshai heev rau O-nplhaib yuav tsum tau sib tw hauv cov txheej txheem ntawm kev ua haujlwm, thiab koj yuav tsum tau xyuam xim kom tsis txhob muaj nws txhua hnub!
