2）機(jī)械密封處的泵軸撓度要小，只有滿足類似這樣的外因，再加上良好的機(jī)械密封自身性能，才能達(dá)到理想的密封效果。二、影響泵用機(jī)械密封的外部原因（一）泵軸的軸向竄量機(jī)械密封的密封面要有一定的比壓（～），從而達(dá)到密封的目的，兩端面的緊密緊密程度可以通過彈簧調(diào)節(jié)。為了保證這個(gè)比壓，要求泵軸不能有太大的竄量（≤），但在實(shí)際生產(chǎn)中，往往泵軸產(chǎn)生很大的竄量。對(duì)機(jī)械密封的使用非常不利的，這種情況在我分廠表現(xiàn)在泵啟動(dòng)過程中，由于不平衡軸向力的存在，使整個(gè)軸發(fā)生向吸入口的竄動(dòng)，造成機(jī)械密封失去密封作用，常用的措施有：葉輪上開平衡孔，泵體上裝平衡管等。（二）泵軸的撓度偏大軸彎曲變形時(shí)橫截面形心沿與軸線垂直方向的線位移稱為撓度，機(jī)械密封要求兩個(gè)密封端面之間受力均勻。但由于泵產(chǎn)品設(shè)計(jì)的不合理，在機(jī)械密封安裝處產(chǎn)生的撓度偏大，使密封處受力不均勻，從而失去密封效果。這種現(xiàn)象大多存在臥式多級(jí)離心泵中。（三）沒有輔助沖洗系統(tǒng)或輔助沖洗系統(tǒng)設(shè)計(jì)不合理機(jī)械密封的輔助沖洗系統(tǒng)是非常重要的，它可以有效的保護(hù)密封面，起到冷卻、潤(rùn)滑、沖走雜物等作用。有時(shí)設(shè)計(jì)人員設(shè)計(jì)不合理，達(dá)不到密封效果；有的設(shè)計(jì)了輔助系統(tǒng)，但由于沖洗液中有雜質(zhì)。</p><p>
