style="text-indent:25px">如何選擇橡膠O型圈：1、橡膠O型圈的內(nèi)徑要預(yù)留出受力發(fā)生形變被壓扁的時候凹槽直徑及受力點方向上的縫隙的長度。2、如果是采用橫向（軸）密封的這個時候要選擇比軸上的直徑長度小1%-3%的橡膠O型圈，這樣一來可以保證O型圈可以緊密的和軸相連不容易脫落，如果是豎向密封的則要選擇內(nèi)徑大1%-3%的O型圈這樣不容易掉下來壓壞。3、根據(jù)實際需求來選擇材質(zhì)比如普通設(shè)備使用液壓油的我們可以選用氟橡膠或者丁腈橡膠，其他的根據(jù)實際情況來選擇。選擇橡膠O型圈的一些原則就這些了，具體情況可以配合我們?nèi)粘Ｊ褂们闆r來靈活應(yīng)用。</p><p style="text-indent:25px">要保證合理的密封性能，動密封和靜密封都要有合適的表面粗糙度。一般靜密封Ra6.3μm~Ra3.2μm，動密封Ra3.2μm~Ra1.6μm。但不是粗糙度越高越好，如果安裝面的粗糙度太高，平直度差，有的會出現(xiàn)凸棱。一方面O型環(huán)被壓縮后，有的面因密封不嚴(yán)而漏油。另一方面O型環(huán)在溝槽中會隨著壓力高的方向向壓力低的方向滑動，造成O型環(huán)損傷，引起泄漏。橡膠O型圈的拉伸率過大，會引起應(yīng)力松弛，造成O型圈的內(nèi)徑增大。造成與軸面形成接觸間隙，安裝過程中會因為振動而使其脫落。同時，橡膠O型圈由于擠壓力度不均勻，影響O型圈的使用壽命。不同形式的靜密封，密封介質(zhì)對O形圈的作用方向是不同的，所以預(yù)壓力設(shè)計也不同。</p><div
