潛污泵的作用是將污水中的雜質(zhì)通過(guò)的方式處理。然后排放掉，與清水泵的不同之處使其技術(shù)要求也不同于普通類(lèi)型的設(shè)備，它的設(shè)計(jì)需要考慮到效率、磨損以及特殊環(huán)境：（1）導(dǎo)板等部件自動(dòng)與著脫耦合，耦合牢固可靠。（2）引出電纜應(yīng)采用YZW和YCW型橡套電纜或性能相同的電纜，且電纜的密封需采用水密頭式密封，確保潛污泵在使用過(guò)程中不至于發(fā)生泄露。（3）葉輪：葉輪設(shè)計(jì)成無(wú)堵塞型式，葉輪皆經(jīng)過(guò)靜平衡試驗(yàn)。葉輪材質(zhì)為HT200,

一般情況下，介質(zhì)的溫度超過(guò)120℃即認(rèn)為是高溫密封。此時(shí)機(jī)械密封存在的主要問(wèn)題有：(1)由于摩擦副端面溫度升高，導(dǎo)致密封端面間液膜氣化，摩擦系數(shù)隨之增大，磨損加劇，溫升加大，密封環(huán)產(chǎn)生熱變形或熱裂而失效；(2)機(jī)械密封中的輔助密封圈材料一般為橡膠或聚四氟乙烯，由于長(zhǎng)時(shí)間在高溫環(huán)境中，容易老化和分解，造成密封失效；(3)高溫下機(jī)械密封的彈性元件易產(chǎn)生疲勞和蠕變，使密封失效；(4)高溫會(huì)加劇金屬材料的腐蝕，縮短機(jī)封的使用壽命。

當(dāng)化工泵輸送介質(zhì)，對(duì)溫度和壓力不高時(shí)，一般選用非金屬密封墊片； </p> <p> 當(dāng)化工泵輸送介質(zhì)為中壓高溫時(shí)，選用非金屬與金屬組合墊片。 </p> <p> 非金屬墊片在泵上應(yīng)用**為普遍，其材料一般為紙、橡膠和聚四氟乙烯。當(dāng)溫度不超過(guò)120℃，壓力在1.0Mpa以下時(shí)，一般選用青殼紙或模造紙墊片。 </p> <p> 如果當(dāng)化工泵輸送介質(zhì)為油，溫度在-30～110℃時(shí)，一般選用耐老化性能較好的丁晴橡膠。當(dāng)當(dāng)化工泵輸送介質(zhì)，在-50～200℃時(shí)，選用氟橡膠更為合適。因?yàn)樗四陀湍蜔嵬?，機(jī)械強(qiáng)度大也是其主要特征。 </p> <p> 在化工泵中由于所輸送介質(zhì)具有腐蝕性，所以一般選用聚四氟乙烯做為墊片材料。隨著化工泵使用的領(lǐng)域越來(lái)越多次，所輸送介質(zhì)種類(lèi)也越來(lái)越多，因此在選用墊片材質(zhì)時(shí)應(yīng)查閱相關(guān)資料或通過(guò)實(shí)驗(yàn)后再做出正確選擇。 </p> <p> <br />

在液體介質(zhì)中工作的機(jī)械密封，一般均依靠液體介質(zhì)在動(dòng)、靜環(huán)摩擦面間所形成的液膜進(jìn)行潤(rùn)滑。因此，維持摩擦面間的液膜是機(jī)械密封穩(wěn)定運(yùn)轉(zhuǎn)、延長(zhǎng)使用壽命所必不可少的。 </p> <p> 強(qiáng)化潤(rùn)滑的結(jié)構(gòu) </p> <p> 靜壓潤(rùn)滑： </p> <p> 所謂靜壓潤(rùn)滑是將有壓力的潤(rùn)滑液體直接引入摩擦面以起到潤(rùn)滑的作用。用此有壓力的潤(rùn)滑液與機(jī)械內(nèi)的流體壓力相對(duì)抗，此種形式通常也稱(chēng)為流體靜壓力密封。引入的潤(rùn)滑液體由單獨(dú)的液源供給，如液壓泵等。只要條件允許，應(yīng)盡可能把氣體介質(zhì)條件轉(zhuǎn)換為液體介質(zhì)條件，這樣既便于潤(rùn)滑又便于密封。氣體介質(zhì)的機(jī)械密封應(yīng)采取措施建立氣膜潤(rùn)滑，如采用氣體靜壓受控膜機(jī)械密封或固體潤(rùn)滑，即選用自潤(rùn)滑材料作動(dòng)環(huán)或靜環(huán)。 </p> <p> 端面偏心： </p> <p> 一般機(jī)械密封，動(dòng)環(huán)的中心、靜環(huán)的中心和軸的中心線都在一條直線上，偏心尺寸不能過(guò)大，特別是對(duì)于高壓，偏心會(huì)使端面所受的壓力不均勻，而造成磨損不均勻。對(duì)于高轉(zhuǎn)速密封，不宜用動(dòng)環(huán)作為偏心環(huán)，否則由于離心力的平衡會(huì)使機(jī)器發(fā)生振動(dòng)。如果將動(dòng)環(huán)或靜環(huán)中的某一個(gè)環(huán)的端面中心做成與軸的中心線偏移部分距離，便能使環(huán)在旋轉(zhuǎn)時(shí)不斷帶入潤(rùn)滑液至滑動(dòng)面間起潤(rùn)滑作用。 </p> <p> <br /> </p> 根據(jù)密封腔體壓力，確定密封結(jié)構(gòu)采用平衡型或非平衡型，單端面或雙端面等。南京化工泵用密封哪家比較便宜</p><p style="text-indent:25px">設(shè)計(jì)輔助沖洗系統(tǒng)，沖洗壓力要求高于密封腔壓力，密封腔壓力要根據(jù)每種泵的結(jié)構(gòu)形式、系統(tǒng)壓力因素來(lái)計(jì)算。鹽城化工泵密封哪家比較好</p><p> 給水泵內(nèi)的高壓水雖經(jīng)過(guò)密封件，但依然有一定的壓力，為了不讓給水泵內(nèi)的水通過(guò)軸與密封件之間的間隙外泄，就從凝結(jié)水泵出口或除鹽水母管引以水源為密封水。 </p> <p> 給水泵內(nèi)的水是具有一定溫度的水，高溫水會(huì)通過(guò)泵的轉(zhuǎn)軸或泵體金屬把熱量傳遞給軸承，使軸承溫度升高。為了控制熱量外傳，所以密封水也起著冷卻的作用。 </p> <p> 在密封水通過(guò)密封件時(shí)，水在軸與密封件之間形成水膜，防止在此處軸與密封件之間的間隙外泄，造成大量的工質(zhì)損失；同時(shí)高溫給水會(huì)通過(guò)泵軸和泵體金屬把熱量傳遞給軸承使軸承溫度升高。嚴(yán)重時(shí)還會(huì)使軸承燒毀；高速旋轉(zhuǎn)的軸與密封件之間的間隙很小，當(dāng)失去密封水時(shí)，此處的水膜也就遭到破壞，軸與密封件很可能發(fā)生摩擦，使給水泵振動(dòng)增大，嚴(yán)重時(shí)將造成設(shè)備損壞。密封水的回水一般采用多級(jí)水封管引入凝汽器。
