Ntxiv rau qhov ua tau raws li cov kev cai dav dav rau cov khoom siv sib khi, cov nplhaib sib khi yuav tsum ua raws li cov hauv qab no:
(1) High elasticity thiab resilience;
(2) Tsim nyog txhua yam muaj zog, suav nrog lub zog tensile, elongation, thiab lub zog tsim kua muag;
(3) Kev ua haujlwm ruaj khov, tsis yooj yim o hauv nruab nrab, thiab thermal shrinkage tsawg (Joule effect);
(4) Yooj yim rau txheej txheem thiab pwm, thiab muaj peev xwm tswj tau qhov ntev;
(5) Tsis yog -corrosive rau qhov chaw sib cuag thiab tsis kis mus rau qhov nruab nrab.
Cov khoom siv zoo tshaj plaws thiab feem ntau siv uas ua tau raws li cov kev xav tau saum toj no yog roj hmab, yog li ntawd, feem ntau sealing nplhaib yog ua los ntawm roj hmab. Muaj ntau hom roj hmab, thiab hom tshiab tau tshwm sim tas li. Thaum tsim thiab xaiv, cov yam ntxwv ntawm ntau yam roj hmab yuav tsum to taub kom xaiv qhov tsim nyog. Raws li ib qho ntawm feem ntau siv txoj kev sib khi, O-rings muaj cov yam ntxwv ua tau zoo hauv qab no: Cov txiaj ntsig muaj xws li kev sib khi zoo heev thiab kev ua haujlwm ntev; me me, lub teeb yuag, thiab tus nqi qis; yooj yim sealing qauv thiab yooj yim sib dhos / disassembly; ib lub nplhaib tuaj yeem muab khi rau hauv ob qho kev qhia; zoo adaptability rau roj, kub, thiab siab; haum rau ob qho tib si zoo li qub thiab dynamic sealing; tsawg dynamic kev sib txhuam tsis kam; thiab standardized qhov ntev thiab grooves, yooj yim xaiv thiab kev yuav khoom sab nraud. Cov kev tsis zoo muaj xws li kev sib txhuam siab heev thaum lub sij hawm dynamic sealing startup, kwv yees li 3-4 zaug ntawm kev sib txhuam quab yuam, thiab qhov zoo li yuav tsum tau nyem rau hauv qhov khoob hauv siab; qhov xav tau rau lubrication thaum siv los ua lub foob hauv cov khoom siv pneumatic los tiv thaiv hnav; thiab cov kev cai nruj rau qhov machining qhov ntev thiab precision ntawm mating Cheebtsam xws li txav chaw, grooves, thiab qhov khoob.
