化工泵軸承室內(nèi)潤滑油注入量太多，其溢出壓力超過了密封阻力。油窗或油位計(jì)安裝位置有誤，誤導(dǎo)了人們對油室內(nèi)潤滑油量的正確判斷.運(yùn)轉(zhuǎn)中油溫的升高使其粘度降低，增加了化工泵泄漏的可能?；赜筒刍蚧赜涂壮叽缙。蚴艿狡渌系K，使被阻滯的液體不能順利返回而造成泄漏?；け盟槿〉慕橘|(zhì)有腐蝕、揮發(fā)、等危險(xiǎn)性的存在，對泵體的密封性能要求，要比其他種類的泵高很多。使用迷宮密封，就加大了化工泵輸送物料泄漏的危險(xiǎn)度。所以，化工泵一般不采用此種密封方法。6、填料密封化工泵填料密封是將富有壓縮性和回彈性的填料放入填料函內(nèi)，依靠壓蓋的軸向壓緊力轉(zhuǎn)化為徑向密封力，從而起到密封作用。這種密封方法稱為填料密封，這種填料稱為密封填料。由于填料密封結(jié)構(gòu)形式簡單，更換方便、價(jià)格低廉、適應(yīng)轉(zhuǎn)速、壓力、介質(zhì)寬泛而在化工泵的設(shè)計(jì)中得到普遍采用。填料密封的原理：在機(jī)械行業(yè)中填料密封主要用作動(dòng)密封，常用作離心泵、壓縮機(jī)、真空泵、攪拌機(jī)的轉(zhuǎn)軸密封。填料裝入填料腔以后，經(jīng)壓蓋螺絲對它作軸向壓縮。當(dāng)軸與填料有相對運(yùn)動(dòng)時(shí)，由于填料的塑性，使它產(chǎn)生徑向力，并與軸緊密接觸。與此同時(shí),填料中浸漬的潤滑劑被擠出，在接觸面之間形成油膜。</p><p>
