Kev sib txhuam yuav cuam tshuam rau kev siv O-ring

Kev sib txhuam thiab hnav yog qhov tseem ceeb cuam tshuam rau O-ring kev puas tsuaj. Qhov degree ntawm hnav feem ntau yog nyob ntawm qhov loj ntawm kev sib txhuam. Thaum cov kua siab me me, kev sib txhuam quab yuam ntawm O-ring nyob ntawm nws qhov ua ntej compression. Thaum cov kua dej ua haujlwm nyob rau hauv qhov siab, qhov kev sib txhuam nce nrog qhov nce ntawm kev ua haujlwm siab.

Thaum lub siab ua haujlwm tsawg dua 20MPa, kev sib raug zoo yog kwv yees li linear. Thaum lub siab ntau dua 20MPa, nrog rau kev nce siab, qhov nce ntawm qhov chaw sib cuag ntawm O-ring thiab cov hlau nto, uas tseem muaj kev cuam tshuam rau daim ntawv thov ntawm O-ring, kev sib txhuam quab yuam nce maj mam. . Raws li ib txwm muaj, lub neej kev pab cuam ntawm O-ring yuav txo qis nyob rau hauv ib square kev sib raug zoo nrog rau qhov nce ntawm cov kua siab. Nrog rau qhov nce ntawm kev sib txhuam, qhov loj ntawm kev sib txhuam kub yog tsim los ntawm kev sib hloov los yog reciprocating ncej thiab O-ring. Txij li feem ntau O-rings yog ua los ntawm roj hmab, thermal conductivity ntawm roj hmab O-rings tsis tshua muaj neeg pluag. Yog li ntawd, kev sib txhuam kub yuav ua rau cov roj hmab laus, ua rau kev ua haujlwm ntawm O-ring thiab ua rau nws cov sealing kev ua tau zoo. Kev sib txhuam tseem yuav ua rau O-ring nto puas, txo cov compression. Kev sib txhuam hnyav yuav sai sai ua rau lub ntsej muag ntawm O-ring puas thiab poob nws cov khoom sib khi.

Kev sib txhuam quab yuam ntawm O-ring muaj kev cuam tshuam zoo rau kev ua haujlwm ntawm O-ring mus rau qhov loj, yog li nws qhov kev sib txhuam quab yuam tsis tuaj yeem tsis quav ntsej thaum siv O-ring.
