3、對于液壓泵，安裝時還要用一個安裝套筒或薄墊片來保護(hù)密封件，以免唇邊翻卷、扭曲，導(dǎo)致彈簧滑出。 4、液壓缸內(nèi)要常用滾壓加工，這樣不但改善了表面的粗糙度，同時還可以做冷作硬化處理，有利于延長密封環(huán)的使用壽命；后續(xù)還需要根據(jù)壓力、滑動面的長度及種類，青海品質(zhì)橡膠密封件制造廠家，這些條件決定“定檢”時間。 5、橡膠密封件面要潤滑狀態(tài)良好、防止顆粒侵入；其次使用規(guī)定的油液和正確的安裝方法，是必要的條件。橡膠密封件安裝或使用不當(dāng)，則容易造成油液泄漏。青海品質(zhì)橡膠密封件制造廠家</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

style="text-indent:25px">在模壓硫化過程中，必須嚴(yán)格正確掌握硫化的溫度、時間和壓力，并隨時注意硫化過程中溫度等參數(shù)的變化情況，進(jìn)行相應(yīng)處理，否則會造成產(chǎn)品欠硫或過硫。若采用自動控制系統(tǒng)，則整個硫化過程會自動記錄和控制，以保證產(chǎn)品達(dá)到正硫化程度。硫化溫度是橡膠O形密封圈發(fā)生硫化反應(yīng)的基本條件之一，它直接影響硫化速度和產(chǎn)品質(zhì)量。硫化溫度高，硫化速度快，生產(chǎn)效率高；硫化溫度低，硫化速度慢。硫化溫度系根據(jù)配方而定，其中較重要的是取決于膠種和所用硫化體系。天然橡膠較適宜的硫化溫度一般為143℃－－150℃，合成橡膠一般為150℃～180℃。硫化時間通常按照確定的硫化溫度，通過試驗確定硫化時間。橡膠制品在硫化過程中加壓，其目的在于使膠料易于流動，充滿型腔，防止硫化過程中產(chǎn)生氣泡，提高產(chǎn)品的致密性。硫化壓力的大小視膠料硬度、模具大小而定。膠料硬度高、模具尺寸大時，壓力可大些，反之則應(yīng)適當(dāng)減小壓力。</p><p style="text-indent:25px">二、橡膠o型圈的安裝： 1、清洗安裝環(huán)境，切勿有雜質(zhì)混入密封裝置，保證橡膠O型圈的正常運轉(zhuǎn)和使用。 2、在安裝橡膠O型圈的時候，一定要小心，切勿被螺紋或者尖角等銳邊切傷或者劃傷，一定要在安裝的軸端與孔端之間留有15°~30°的引入角。 3、安裝的時候，要檢查安裝的位置正不正確。 4、切勿發(fā)生橡膠O型圈扭曲的現(xiàn)象。如有發(fā)現(xiàn)立即整改。 5、安裝的時候一定要注意擋圈的方向。 6、保證它的潤滑。盡量用所密封的液體來潤滑。如果不是，也一定保證潤滑劑是液體。 7、在安裝前，一定要保證橡膠O型圈的質(zhì)量。不可出現(xiàn)毛邊、內(nèi)刺等現(xiàn)象，并且保證不是二次循環(huán)利用。O型橡膠圈是一種截面為圓形的橡膠圈，因其截面為O型，故稱其為O型橡膠圈。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

style="text-indent:25px">橡膠密封件的發(fā)展趨勢：隨著環(huán)保、汽車多樣化、橡膠可再生利用、材料耐熱性等要求的提高，進(jìn)一步降低成本已經(jīng)成為汽車用橡膠制品發(fā)展的主要方向。密封制品占汽車用橡膠件重量的25%-28%(除輪胎)。近來具有耐臭氧、耐氣候老化性能的EPDM膠被普遍應(yīng)用于汽車門窗密封條中，并逐步取代傳統(tǒng)的NR和CR膠。每輛車可使用10-15米長的各種密封條。為進(jìn)一步降低成本和外形美觀，國外廠商已用TPE材料來制造汽車門窗密封條。橡膠密封件是密封裝置中的一類通用基礎(chǔ)元件，在泄漏和密封這一對矛盾中扮演十分重要的角色，在人類征服自然的過程中解決泄漏和密封問題。一直在推動技術(shù)進(jìn)步，是防止和減少環(huán)境污染的重要途徑。橡膠可分為固態(tài)橡膠、乳狀橡膠、液體橡膠和粉末橡膠。河北高效橡膠密封件生產(chǎn)工藝</p><p
