parker擋圈的標(biāo)準(zhǔn)材質(zhì)為N300-90(一種丁晴橡膠NBR為基質(zhì)的合成橡膠,硬度為邵氏A90°)
選用O型圈時(shí)必須考慮硬度,對(duì)于大多數(shù)密封運(yùn)用場(chǎng)合,邵氏硬度A70°的材質(zhì)便可以獲得佳的性能.
一般來(lái)講 在此硬度范圍內(nèi)的O型圈,低壓密封性較好.但在高壓時(shí)他們比硬度高的橡膠件更容易被擠出.
但硬度高的材料不易跟隨密封表面的不平度或變形,較硬的O型圈在低壓時(shí)也更容易泄露,
硬度高的O型圈,不使用與運(yùn)動(dòng)條件下密封.
低硬度的O型圈的耐磨性加上抗高擠壓硬材料的擋圈.就容易獲得很好低壓密封性能.
