Qhov Ncauj Coj Ua Ntej Rau Txoj Kev Cuam Tshuam ntawm O Ring Ring
Jun 15, 2017

O Ring Ringing nyob rau kev rhuav tshem ntawm kev paub txog, tus Vajntxwv nram qab no yuav muab ib qho kev qhia me ntsis.

Raws li O Ring Ring Seals nrog cov khoom siv roj hmab hluav taws xob yog cov khoom siv viscoelastic, yog li pib txheej txheem ntawm kev sib txuam thiab kev tiv thaiv kab thaiv tom qab lub sijhawm ntev, yuav tsim tau lub suab deev tas li thiab maj mam poob, thiab thaum kawg tawm. Kev ua kom deformation thiab elasticity ntawm O Ring Seal yog vim li cas tseem ceeb rau kev poob kev sealing.

1, qhov ntsuas kub ntawm O Ring Ring Seals mus tas li deformation

Kev ntsuas kub yog qhov tseem ceeb tshaj plaws uas cuam tshuam rau lub cev ntaj ntawm O Ring Ring. Kev kub siab yuav ua rau cov laus siv cov roj hmab. Qhov siab tshaj ntawm kev khiav hauj lwm kub, qhov ntau dua qhov txheej txheem ntawm O Ring Ring Seals. Thaum lub caij nyoog deformation ntawm ntau tshaj 40%, O Ring Ring Seal ntawm qhov poob peev txheej thiab ntub. Thawj qhov kev nyuab siab ua rau cov khoom siv roj ntawm O Cov Nplhaib Ntsaws ruaj khov vim compression deformation yuav maj mam txo cov txheej txheem ntawm O Ring Ring thiab kub poob. Cov Nplhaib O nplhaib, uas ua haujlwm ntawm xoom kub, tej zaum yuav pib los txo los yog tag nrho ploj vim muaj kev txo qis heev hauv qhov kub. Nyob rau hauv rooj plaub ntawm -50 ~ -60 ° C, cov khoom siv roj qis tsis tshua muaj peev xwm poob tag thawj zaug kev nyuab siab; txawm tias cov khoom kub tsis tshua muaj roj, cov kev ntxhov siab thaum pib lub sij hawm no yuav tsis ntau dua 20 ℃ thaum pib kev ntxhov siab ntawm 25%. Qhov no yog vim hais tias thawj zaug pib ntawm qhov O Ring Ringing yog nyob ntawm lub coefficient ntawm linear expansion. Yog li, thaum xaiv qhov pib ntawm lub compression, nws yog ib qho tsim nyog los xyuas kom meej tias muaj peev xwm sib khi tau zoo tom qab kev ntxhov siab poob vim kev so kom txaus thiab kub poob.

Qhov ntsuas kub ntawm txoj haujlwm O Cov Nplhaib, yuav tsum tau ua tib zoo saib xyuas rau cov khoom siv roj hmab rov qab thiab cov qauv kev deformation.

Hauv txoj kev los, hauv tus tsim yuav tsum sim xyuas kom meej tias O Ring Ring Seals nrog rau kev khiav hauj lwm kub, los yog siv cov khoom kub thiab tsis tshua muaj O O Ring Seals rau cov kev pab cuam lub neej.

2, qhov sib hloov nquag thiab qhov nyiaj ntawm qhov ncuaj cuam tshuam rau qhov "deformation tas li"

Qhov tshwm sim rau kev tswj kev nyuaj siab ntxhov plhuav tshwm sim hauv lub xeev cov nyom, thiab kev ntxhov siab nruj nrog rau qhov nce ntawm lub sijhawm. Qhov ntev ntawm kev siv lub sij hawm, qhov ntau dua qhov sib txuam thiab qhov nyiaj ntawm elongation, qhov ywj siab ntawm kev nyuaj siab los ntawm qhov ntau dua qhov kev nyuab siab, kom O Ring Ring Seal elasticity, poob peev txheej sealing. Yog li ntawd, nws yog ib lub tswv yim kom sim txo cov nqi txhawm rau hauv kev siv cai. Nce qhov sib npaug ntawm O Ring Ring Seals yog qhov yoojyim tshaj los txo cov nqi nias ceev, tab sis qhov no ua rau kom muaj qhov loj ntawm cov qauv.

Nws yuav tsum raug sau tseg tias cov neeg nyob hauv kev sib piv ntawm cov nqi nquag, feem ntau tsis nco O Ring Seal hauv lub rooj sib txoos thaum cov teeb meem tshwm sim los ntawm kev txo ntawm qhov siab qhov kev sib tshuam. Qhov kev hloov ntawm cheeb tsam ntawm O-Ring Seals yog ntxim rau qhov nws qhov txawv ntawm qhov txawv. Thaum tib lub sijhawm, vim yog lub luag haujlwm ntawm kev nruj, O Ring Sealing Cross-sectional hloov yuav hloov, nws qhia tau qhov siab ntawm qhov txo. Tsis tas li ntawd, nyob rau hauv qhov chaw nro, cov nplaim sab nrauv ntawm O Cov Nplhaib Ruaj yuav ua kom zoo dua qub, uas yog, qhov siab ntawm qhov kawg yog qhov txo me ntsis. Qhov no kuj yog qhov kev ua ntawm O Ring Ring Seals kom nruj kev nyuaj siab.
