<p> (1) 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，連云港中型機(jī)械密封中間商、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(rùn)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(duì)轉(zhuǎn)動(dòng)。③動(dòng)、靜環(huán)輔助密封由于受到污水中的弱酸，連云港中型機(jī)械密封中間商、弱堿的腐蝕，連云港中型機(jī)械密封中間商,橡膠件已無(wú)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(wèn)題,現(xiàn)采取如下措施:①保證下端蓋、油室的清潔度,對(duì)不清潔的潤(rùn)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(duì)高揚(yáng)程泵應(yīng)重新設(shè)計(jì)機(jī)封構(gòu),對(duì)腐蝕性介質(zhì)橡膠應(yīng)選用耐弱酸、弱堿的氟橡膠。機(jī)封靜環(huán)應(yīng)加防轉(zhuǎn)銷。

碳化硅有反應(yīng)燒結(jié)碳化硅、常壓燒結(jié)碳化硅和熱壓碳化硅。 </p> <p> 硬質(zhì)合金。硬質(zhì)合金主要是碳化鎢WC，分別有鈷基碳化鎢WC-Co、鎳基碳化鎢WC-Ni和鈷-鎳基碳化鎢WC-Co-Ni。碳化鎢的特點(diǎn)：硬度高，耐磨性好；機(jī)械強(qiáng)度高，抗彎性好；導(dǎo)熱率較高而膨脹系數(shù)較小，密封面摩擦熱容易導(dǎo)出；無(wú)鈷硬質(zhì)合金耐腐蝕性較好。 </p> <p> <p> 作為輔助密封圈的材料有橡膠、塑料、石棉、膨脹石墨、石墨和金屬脹圈等。橡膠圈是使用**廣的一種輔助密封圈。常用的橡膠密封圈材料有丁腈橡膠、氟橡膠、硅橡膠、氯丁橡膠、丁苯橡膠等。 </p> <p> 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(lái)，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。 </p>
