O型密封墊圈的優優點和缺點
優點和缺點：
1)隔絕器官的結構單(dan)純(chun)，按照器官狹窄，含(han)量較小；
2)有(you)自(zi)封密功用(yong)，總(zong)是只單(dan)單(dan)的封密件(jian)便能進(jin)行封密，不須得周期時間性改(gai)變；
3)密(mi)閉的(de)性能最好，做(zuo)為靜密(mi)閉時需要(yao)說需要(yao)真(zhen)正做(zuo)到都沒有流出；
4)運行磨蹭摩擦力較小，針對工作壓力交變的場(chang)景可以適用于(yu)；
5)長度和管溝已細則化，資(zi)金低(di)，有利于選(xuan)用和購(gou)入。
不足之處：
1)用來擠壓膠封時，發動擠壓障礙大；
2)假如動用不(bu)良(liang)，輕易(yi)導(dao)致O形圈切、擠、扭、斷等問題。
3)動封嚴(yan)很困難做的不泄漏，會設定滲漏量越來越于暫行規定批準值。
4)在某種環境選擇，之(zhi)所(suo)以需求改(gai)加防護擋圈和(he)防灰圈。在汽壓和(he)通水壓力等(deng)填料密封中(zhong)，突然還需求配有潤滑情況所(suo)屬設(she)備。
