<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、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、弱堿的腐蝕,橡膠件已無(wú)彈性。有的已腐爛，蘇州密封制造廠家，蘇州密封制造廠家,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(xiāo)。機(jī)械密封的密封面要有一定的比壓，蘇州密封制造廠家，從而達(dá)到密封的目的，兩端面的緊密緊密程度可以通過(guò)彈簧調(diào)節(jié)。蘇州密封制造廠家</p><div
