</p> <p> 離心泵停機(jī)主要是由機(jī)械密封的失效造成的。失效的表現(xiàn)大都是泄漏，泄漏原因有以下幾種： </p> <p> 動(dòng)靜環(huán)密封面的泄漏，原因主要有：端面平面度，粗糙度未達(dá)到要求，或表面有劃傷；端面間有顆粒物質(zhì)，造成兩端面不能同樣運(yùn)行；安裝不到位，方式不正確。 </p> <p> 補(bǔ)償環(huán)密封圈泄漏，原因主要有：壓蓋變形，預(yù)緊力不均勻；安裝不正確；密封圈質(zhì)量不符合標(biāo)準(zhǔn)；密封圈選型不對(duì)。 </p> <p> <br /> </p> <p> 液體介質(zhì)潤(rùn)滑性較差，加之操作壓力過(guò)載，兩密封面追蹤轉(zhuǎn)動(dòng)不同步。例如高轉(zhuǎn)速泵轉(zhuǎn)速為20445r/min，密封面中心直徑為7cm，泵運(yùn)轉(zhuǎn)后其線速度高達(dá)75 m/s，當(dāng)有一個(gè)密封面滯后不能追蹤旋轉(zhuǎn)，瞬時(shí)高溫造成密封面損壞。 </p> <p> <br /> </p><p> 泵體也稱泵殼，它是水泵的主體。起到支撐固定作用，并與安裝軸承的托架相連接。 </p> <p> 泵軸的作用是借聯(lián)軸器和電動(dòng)機(jī)相連接，將電動(dòng)機(jī)的轉(zhuǎn)矩傳給葉輪，所以它是傳遞機(jī)械能的主要部件。 </p> <p> 滑動(dòng)軸承使用的是透明油作潤(rùn)滑劑的，加油到油位線。太多油要沿泵軸滲出，太少軸承又要過(guò)熱燒壞造成事件！在水泵運(yùn)行過(guò)程中軸承的溫度比較高在85度，一般運(yùn)行在60度左右。 </p> <p> <br /> </p> <p> 密封環(huán)又稱減漏環(huán)。 </p> <p> 填料函主要由填料、水封環(huán)、填料筒、填料壓蓋、水封管組成。填料函的作用主要是為了封閉泵殼與泵軸之間的空隙，不讓泵內(nèi)的水流流到外面來(lái)也不讓外面的空氣進(jìn)入到泵內(nèi)。始終保持水泵內(nèi)的真空！當(dāng)泵軸與填料摩擦產(chǎn)生熱量就要靠水封管住水到水封圈內(nèi)使填料冷卻！保持水泵的正常運(yùn)行。所以在水泵的運(yùn)行巡回檢查過(guò)程中對(duì)填料函的檢查是特別要注意！在運(yùn)行600個(gè)小時(shí)左右就要對(duì)填料進(jìn)行更換。

實(shí)際使用效果表明，密封元件失效**多的部位是動(dòng)，靜環(huán)的端面，離心泵機(jī)封動(dòng)，靜環(huán)端面出現(xiàn)龜裂是常見(jiàn)的失效現(xiàn)象，主要原因有： </p> <p> 安裝時(shí)密封面間隙過(guò)大，沖洗液來(lái)不及帶走摩擦副產(chǎn)生的熱量；沖洗液從密封面間隙中漏走，造成端面過(guò)熱而損壞。 </p> <p> 液體介質(zhì)汽化膨脹，使兩端面受汽化膨脹力而分開(kāi)，當(dāng)兩密封面用力貼合時(shí)，破壞潤(rùn)滑膜從而造成端面表面過(guò)熱。 </p> <p> 液體介質(zhì)潤(rùn)滑性較差，加之操作壓力過(guò)載，兩密封面追蹤轉(zhuǎn)動(dòng)不同步。例如高轉(zhuǎn)速泵轉(zhuǎn)速為20445r/min，密封面中心直徑為7cm，泵運(yùn)轉(zhuǎn)后其線速度高達(dá)75 m/s，當(dāng)有一個(gè)密封面滯后不能追蹤旋轉(zhuǎn)，瞬時(shí)高溫造成密封面損壞。 </p> <p> 密封沖洗液孔板或過(guò)濾網(wǎng)堵塞，造成水量不足，使機(jī)封失效。 </p> <p> <br /> 江蘇地區(qū)口碑好離心泵生產(chǎn)廠家——靖江市瑞鑫泵業(yè)有限公司。浙江大型離心泵配件</p><p style="text-indent:25px">離心泵廠家，歡迎您的來(lái)電咨詢——靖江市瑞鑫泵業(yè)有限公司。浙江大型離心泵配件</p><p> 但在處理泵的振動(dòng)問(wèn)題時(shí)卻通常是首先考慮的因素。引起振動(dòng)的這一類原因的主要原因包括：a.臨界轉(zhuǎn)速問(wèn)題——這類問(wèn)題實(shí)際上在以全速運(yùn)行的臥式泵內(nèi)是不存在的：生產(chǎn)商已對(duì)泵進(jìn)行了設(shè)計(jì)，因此其臨界轉(zhuǎn)速將高出高轉(zhuǎn)速。("臨界轉(zhuǎn)速"指激起旋轉(zhuǎn)設(shè)備自然頻率的理論角速度。旋轉(zhuǎn)速度達(dá)到自然頻率時(shí)便發(fā)生振動(dòng)和共振。)在立式泵(如具有各類長(zhǎng)度和轉(zhuǎn)頭的立式渦輪機(jī))內(nèi)，臨界轉(zhuǎn)速應(yīng)在制造之前予以考慮。在臥式泵內(nèi)，臨界轉(zhuǎn)速通常由超速、缺少管道支撐件或未考慮的多泵組引起。(缺少管道支撐件時(shí)，管道實(shí)際上成為了"泵的一部分"，且系統(tǒng)的臨界轉(zhuǎn)速與泵的臨界轉(zhuǎn)速不同。)這與下文將討論的外部原因引起的問(wèn)題相類似?？刹捎脙煞N方法糾正臨界轉(zhuǎn)速問(wèn)題，將振動(dòng)減少至可接受水平：1.改變泵的自然頻率，這一操作應(yīng)咨詢泵生產(chǎn)商或在其協(xié)助下進(jìn)行。屬于常用方法。2.改變轉(zhuǎn)速(針對(duì)VFD系統(tǒng)時(shí)尤為有用)。通過(guò)臨界轉(zhuǎn)速"鎖定"或加速以預(yù)防機(jī)械運(yùn)轉(zhuǎn)。b.嚴(yán)重氣濁——?dú)鉂徇_(dá)到一定嚴(yán)重程度時(shí)(由NPSH或攜入的空氣引起)，內(nèi)爆的能量將引起整個(gè)裝置急劇振動(dòng)。當(dāng)然，隨著氣濁的繼續(xù)，泵輪材料將被腐蝕，振動(dòng)也進(jìn)一步加劇。合理選用泵則可避免此類情況出現(xiàn)，但隨著系統(tǒng)老化以及管道改變這類情況仍可發(fā)生。浙江大型離心泵配件</p><p
