Kev sib txhuam thiab kev siv O-ring
Hauv cov khoom siv sib khi zoo, kev sib txhuam thiab hnav yog qhov tseem ceeb cuam tshuam rau kev puas tsuaj ntawm O-rings. Lub 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 pre-compression. Thaum cov kua dej ua haujlwm nyob rau hauv siab, kev sib txhuam yuav nce ntxiv thaum lub zog ua haujlwm nce. Thaum lub siab ua haujlwm tsawg dua 20MPa, qhov kev sib raug zoo yog kwv yees. Thaum lub siab ntau dua 20MPa, raws li lub siab nce, qhov nce ntawm qhov chaw sib cuag ntawm O-ntiv nplhaib thiab cov hlau nto maj mam maj mam qeeb, thiab qhov nce ntawm kev sib txhuam kuj qeeb raws li. Feem ntau, kev pab cuam lub neej ntawm O-ring yuav txo qis hauv qhov kwv yees kwv yees kev sib raug zoo nrog kev nce siab ntawm cov kua.
