Cov duab tuaj yeem muaj qhov sib txawv, xws li x-shaped profile, feem ntau hu ua X-ntiv nplhaib, Q-ntiv nplhaib, lossis los ntawm lub npe lag luam Quad Ring.

Q: Ua li cas koj thiaj paub tias O-ring tsis zoo?

A: Lub O-Ring tsim ragged npoo uas tshwm tattered, feem ntau yog vim muaj kev tshem tawm ntau dhau. Lub O-Ring tuaj yeem pom cov kab nrib pleb tawg nyob rau ntawm qhov chaw kub siab tshaj plaws. Tsis tas li ntawd, qee cov elastomers tuaj yeem pom cov cim ntawm softening. Qhov no yog vim raug tshav kub ntau dhau.Vim nws muaj peev xwm ncav cuag O-ring txoj kab uas hla mus txog 5% thiab compress nws mus txog 3%, koj tuaj yeem xaiv qhov loj me: 305 x 5 mm (nrog tsuas yog 1% stretch), los yog 310 x 5 mm (tsuas yog 0.6% compression).

Q: Puas yog silicone O-rings zoo dua?

A: Silicone muaj npe nrov rau muaj ib qho kev ua haujlwm kub tshaj plaws ntawm ib qho elastomer, nrog rau kev ua tau zoo heev thiab qis compression txheej txheem. Silicone 'O' rings kuj tuaj yeem muab sib xyaw ua cov nplaim hluav taws xob, hluav taws xob tiv thaiv thiab kev ua haujlwm.Ntxiv mus, HNBR cov ntsaws ruaj ruaj ntsws ntsws thaum laus vim muaj qhov cuam tshuam sib cuam tshuam. Ntawm O-rings uas muaj hnub nyoog nyob rau hauv lub xeev uncompressed, lub shrinkage yog hais txog 2% tom qab 184 d ntawm 150 degree thiab txog 1.5% tom qab 365 d ntawm 125 degree.

Q: Yuav tsum O-rings nyuaj?

A: Lub hardness ntawm roj hmab o-ring tebchaw yog ntsuas los ntawm Shore A durometer; qhov siab dua lub durometer, qhov nyuaj ntawm cov compound. 70-durometer hardness yuav tsum tau siv thaum twg los tau raws li nws muaj qhov zoo tshaj plaws ua ke ntawm cov khoom rau feem ntau o-ring daim ntaub ntawv.

Q: Yuav ua li cas hloov tau O-rings?

A: O-Ring yam ntxwv
Raws li lawv tau ua los ntawm cov khoom siv roj hmab hloov tau yooj yim, cov khoom siv no muaj ntau yam thiab muaj lub peev xwm los deform lawv tus kheej kom haum rau txhua yam uas pom nyob rau hauv cov kab noj hniav uas nyob ze ntawm qhov sib txawv. Yog hais tias koj xav kom ntsiag to ntawm cov keyboard thiab soften lub tsaws, tau mos o-rings, piv txwv li nyob rau hauv 40A los yog 50A durometer.Pulses ntawm siab siab yuav ua rau lub clearance sib txawv ntawm cov mating npoo qhib thiab kaw. Qhov no tuaj yeem ua rau O-ring tau daig ntawm cov npoo ntse ntawm cov npoo npoo, ua rau lub cev puas tsuaj rau lub foob nto feem ntau hu ua nibbling.
