O-rings muaj kev hnav tsis zoo

Thaum muaj qhov sib txawv ntawm qhov sib txuas, cov plua plav thiab cov xuab zeb los ntawm qhov chaw ua haujlwm tau ua raws li lub piston pas nrig nto thiab nqa mus rau hauv lub tog raj kheej nrog rau cov roj zaj duab xis thaum lub sij hawm reciprocating piston pas nrig. Cov khoom no dhau los ua cov khoom abrasive uas nkag mus rau O- nplhaib nto, ua kom O- nplhaib hnav thiab thaum kawg ua rau nws poob nws txoj kev sib khi. Txhawm rau zam qhov no, cov nplhaib plua plav yuav tsum tau siv rau ntawm qhov txuas txuas ntxiv ntawm cov khoom siv sib khi sib khi.

Qhov roughness ntawm zawv zawg nto yog qhov ncaj qha cuam tshuam rau kev sib txhuam thiab hnav ntawm O- nplhaib nto.

Feem ntau hais lus, lub ntsej muag du ua rau muaj kev sib txhuam tsawg thiab hnav, yog li tus nqi roughness ntawm zawv zawg nto feem ntau qis heev (Ra 0.2-}0.050 μm). Txawm li cas los xij, cov kev ntsuam xyuas pom tau tias qhov tsis zoo ntawm qhov tsis zoo (Ra qis dua 0.050 μm) tuaj yeem ua rau muaj kev sib txhuam thiab hnav tsis zoo. Qhov no yog vim cov feeb deg irregularities pab tuav ib tug tsim nyog lubricating roj zaj duab xis. Yog li ntawd, cov kev cai saum npoo tsim nyog yuav tsum tau xaiv. Cov khoom ntawm zawv zawg nto kuj cuam tshuam rau lub neej ntawm O- nplhaib. Qhov ntau dua qhov nyuaj, hnav tsis kam, thiab muaj peev xwm tswj tau qhov chaw du ntawm cov khoom siv zawv zawg, lub neej ntev ntawm O-ring. Qhov no kuj yog ib qho laj thawj tseem ceeb rau chrome plating rau saum npoo ntawm hydraulic lub tog raj kheej piston rods.

Hauv cov khoom siv sib khi zoo, kev sib txhuam thiab hnav yog qhov tseem ceeb cuam tshuam rau O-ring puas. Qhov℃ntawm hnav feem ntau yog nyob ntawm qhov loj ntawm kev sib txhuam quab yuam. Thaum cov kua siab qis, qhov loj ntawm kev sib txhuam ntawm lub nplhaib O- nyob ntawm nws qhov ua ntej- compression.

Kev sib txhuam ntau zog ua rau muaj ntau qhov sib txhuam kub ntawm lub rotating lossis reciprocating ncej thiab O- nplhaib. Txij li feem ntau O-rings yog ua los ntawm roj hmab, uas muaj cov thermal conductivity tsis zoo, qhov kev sib txhuam kub ua rau cov roj hmab laus, ua rau O-ring tsis ua hauj lwm thiab cuam tshuam nws txoj kev sib khi. Kev sib txhuam kuj ua rau muaj kev puas tsuaj rau lub nplhaib O-, txo nws cov compression. Kev sib txhuam hnyav tuaj yeem ua rau lub ntsej muag puas tsuaj sai rau O- nplhaib, ua rau poob ntawm nws cov khoom sib khi.
