淺談液壓系統(tǒng)活塞組件的密封

液壓系統(tǒng)活塞裝置主要用來(lái)防止液壓油的洩漏，良好的密封是 液壓缸傳遞動(dòng)力、正常動(dòng)作的保證，根據(jù)兩個(gè)需要密封的耦合面間有無(wú)相對(duì)運(yùn)動(dòng)，可把密封分爲(wèi)動(dòng)密封和靜密封兩大類(lèi)。
設(shè)計(jì)或選用密封裝置的基本要求是具有良好的密封性能，并隨壓力的增加能自動(dòng)提高密封性，除此以外，摩擦阻力要小、耐油、抗腐蝕、耐磨、壽命長(zhǎng)、制造簡(jiǎn)單、拆裝方便。
常見(jiàn)的密封方法有間隙密封、活塞環(huán)密封和密封圈密封。

間隙密封是常用的密封方式，依靠相對(duì)運(yùn)動(dòng)的零件配合面之間的微小間隙來(lái)防止洩漏。
活塞環(huán)密封依靠安裝在活塞環(huán)形槽內(nèi)彈性金屬環(huán)緊貼缸筒內(nèi)壁實(shí)現(xiàn)密封。
密封圈密封是液壓系統(tǒng)中應(yīng)用最爲(wèi)廣泛的一種密封，密封圈有O形圈、V形圈、 Y形圈及組合式等數(shù)種，任何形狀的密封圈在安裝時(shí)，必須保證有適當(dāng)?shù)念A(yù)壓縮量，過(guò)小不能密封，過(guò)大則會(huì)導(dǎo)緻摩擦力增大，且易于損壞，因此，大蘭液壓小編提醒大家安裝密封圈的溝槽尺寸和表面精度必須按有關(guān)圖紙給出的數(shù)據(jù)嚴(yán)格執(zhí)行。
