715kW以下小自吸式離心泵機(jī)封失效常常產(chǎn)生磨軸,磨軸位置主要有以下幾個(gè):動(dòng)環(huán)輔助密封圈處、靜環(huán)位置、少數(shù)彈簧有磨軸現(xiàn)象。 </p> <p> (2)磨軸的主要原因:①BIA型雙端面機(jī)械密封,反壓狀態(tài)是不良的工作狀態(tài),介質(zhì)中的顆粒、自吸式磁力泵雜質(zhì)很容易進(jìn)入密封面,使密封失效。②磨軸的主要件為橡膠波紋管,且是由于上端密封面處于不良潤滑狀態(tài),動(dòng)靜環(huán)之間的摩擦力矩大于橡膠波紋管與軸之間的傳遞轉(zhuǎn)矩,發(fā)生相對轉(zhuǎn)動(dòng)。③動(dòng)、靜環(huán)輔助密封由于受到污水中的弱酸、弱堿的腐蝕,橡膠件已無彈性。有的已腐爛,失去了應(yīng)有的功能,產(chǎn)生了磨軸的現(xiàn)象。 </p> <p> (3)為解決以上問題,現(xiàn)采取如下措施:①保證下端蓋、油室的清潔度,對不清潔的潤滑油禁止裝配。不銹鋼齒輪油泵②機(jī)封油室腔內(nèi)油面線應(yīng)高于動(dòng)靜環(huán)密封面。③根據(jù)不同的使用介質(zhì)選用不同結(jié)構(gòu)的機(jī)封。對高揚(yáng)程泵應(yīng)重新設(shè)計(jì)機(jī)封構(gòu)，蘇州機(jī)械密封廠家推薦,對腐蝕性介質(zhì)橡膠應(yīng)選用耐弱酸，蘇州機(jī)械密封廠家推薦、弱堿的氟橡膠。機(jī)封靜環(huán)應(yīng)加防轉(zhuǎn)銷。影響密封的主要因素有哪些？密封本身質(zhì)量、工藝操作條件，蘇州機(jī)械密封廠家推薦、裝配安裝精度、主機(jī)本身精度、密封輔助系統(tǒng)。蘇州機(jī)械密封廠家推薦</p><div

丁腈橡膠是常用的一種耐油橡膠。它是丁二烯和丙烯腈的共聚物。根據(jù)丙烯腈含量多少分成若干種：低丙烯腈（丁腈-18）、中丙烯腈（丁腈-26）和高丙烯腈（丁腈-40）、丙烯腈含量越高，它的耐油性越好，抗張強(qiáng)度、硬度和耐磨性、耐水性增加，透氣性減小。隨之而來，它在極性溶劑中是溶解度卻增大，耐腐蝕性也受到影響，彈性和耐寒性也變差。丁腈橡膠不耐撓曲，抗撕裂也較差。<span style="font-size:12px;">O形圈是相對來說比較流行的密封件，主要用于靜態(tài)密封應(yīng)用中（這意味著在密封表面之間或在密封表面與其配合表面之間沒有運(yùn)動(dòng)）。Seals-Shop提供的O形圈的橫截面范圍為0.8到8.4 mm，內(nèi)徑較大程度為810 mm。O形圈可用于密封幾乎所有的液體和氣體介質(zhì)，并且可用彈性體和其他材料制成，包括乙丙二烯單體（EPDM）橡膠，含氟彈性體（FKM）和丁腈橡膠（NBR）。</span> 蘇州機(jī)械密封的用途和特點(diǎn)密封件必須存放在密封包裝內(nèi)，避免和空氣中的水分或塵埃接觸。</p><div style="width:100%;text-align: center;"><img
