螺紋密封在泵上一般有兩種形式，一種是螺紋聯(lián)接墊片密封，一種是螺紋加填充濟密封，二者皆用于小直徑螺紋連接的密封場合。螺紋聯(lián)接墊片密封的密封件是墊片，而螺紋只起提供壓緊力的作用。密封的效果除了墊片的本身性能外。密封面的粗糙度以及與螺紋孔的相對幾何位置精度對密封效果影響也很大。于由密封墊片在擰緊螺紋時不僅承受壓緊力，浙江油泵密封可定制企業(yè)，還承受扭矩，使墊片產(chǎn)生變形甚至損壞，因此，當(dāng)墊片為非金屬時，一般只適用于壓力不高的場合，如果墊片為金屬則適用壓力可達(dá)30Mpa以上。 </p> <p> 泵上經(jīng)常使用的絲堵，則是另一種螺紋密封形式。由于考慮到絲堵制造的經(jīng)濟性，一般單靠螺紋的配合不能起到密封作用，往往用生膠帶，密封膠等填充物填充螺紋的密封間隙。其承壓能力取決于螺紋的制造精度和材質(zhì)，與絲堵和螺紋孔的配合形式?jīng)]有關(guān)系。螺紋孔與絲堵無論采用"錐對錐"還是"柱對錐"，密封效果相同，只是使用地域不同而已。我國目前兩種形式同等采用。影響密封效果的常見原因是在加工螺紋底孔時尺寸偏大，使螺紋牙形變短，牙頂變寬，造成密封面減小，當(dāng)密封壓力升高后產(chǎn)生泄漏，甚至將絲堵壓出，浙江油泵密封可定制企業(yè)。泄漏通道也可同時存在，浙江油泵密封可定制企業(yè)，但一般有主次區(qū)別，只要觀察細(xì)致，熟悉結(jié)構(gòu)，一定能正確判斷。浙江油泵密封可定制企業(yè)</p><div

一般情況下，介質(zhì)的溫度超過120℃即認(rèn)為是高溫密封。此時機械密封存在的主要問題有：(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，由于長時間在高溫環(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)高溫會加劇金屬材料的腐蝕，縮短機封的使用壽命。浙江油泵密封可定制企業(yè)對于含有固體顆粒介質(zhì)，密封面進(jìn)入固體顆粒是導(dǎo)致使密封失效的主要原因。</p><div

style="font-size:12px;"> 非平衡型密封的旋轉(zhuǎn)面相反一側(cè)的截面完全暴露于填料盒的壓力范圍之下，這種情況會使密封面之間產(chǎn)生很高的密封壓力，從而會使工作溫度提高，加快磨損速度。在高溫工作條件下或液體具有較大腐蝕性和磨擦性的情況下，會極大降低機械密封的使用壽命。</span> </p> <p> <span style="font-size:12px;"> 對機械密封加以平衡，可降低密封壓力，延長密封的使用壽命。一般采用帶有臺階的主軸和軸套，降低旋轉(zhuǎn)面的有效截面，就可達(dá)到上述目的。不過千萬別將凈密封壓力調(diào)節(jié)到接近零的水平，因為這樣做的結(jié)果可能會造成密封面之間的工作狀況不穩(wěn)定，并可能會因突然的變故而將密封吹開。</span> </p> <p> <span style="font-size:12px;"> 解決這些密封問題的答案也許是采用非平衡式密封，對于某些服務(wù)來說，也許采用非平衡式密封能達(dá)到更好的效果。例如，在某些應(yīng)用領(lǐng)域，與密封的使用壽命相比，也許更強調(diào)對液體泄漏造成的安全性問題。在這種情況下，對密封的選用也許可理解為更希望選擇具有較高的密封壓力。同樣，在選用較冷液體的密封時，操作溫度的增加也許是微不足道的。</span> </p> <p>

潛污泵的作用是將污水中的雜質(zhì)通過的方式處理。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型的設(shè)備，它的設(shè)計需要考慮到效率、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程中不至于發(fā)生泄露。（3）葉輪：葉輪設(shè)計成無堵塞型式，葉輪皆經(jīng)過靜平衡試驗。葉輪材質(zhì)為HT200, 符合GB9439-88的要求，過流表面光潔無粘砂、尖角、冷隔、氣孔、砂眼等缺點。（4）主軸材質(zhì)選用3Cr13經(jīng)調(diào)質(zhì)處理，有效地、可靠地傳遞動力。主軸與葉輪用鍵連接，以傳遞動力。主軸與葉輪用葉輪螺母鎖緊并有止退墊片，可防止水泵倒轉(zhuǎn)，造成葉輪松脫。（5）密封環(huán)：材質(zhì)鑄造青銅，防止因銹蝕而與葉輪咬死。設(shè)有密封環(huán)可更大限度地減少內(nèi)部泄露，提高水泵的效率。（6）機械密封：采用兩套單端面非平衡型機械密封。油腔和電機室之間的上部密封單元由陶瓷，石墨組成；泵殼和油腔之間的下部密封單元由碳化硅，碳化硅組成，以防接觸介質(zhì)。

同時溶于液體中的氧等活潑氣體也使金屬產(chǎn)生腐蝕。由于化學(xué)腐蝕與機械剝蝕的共同作用，加快了金屬損壞的速度，從而使葉輪受到破壞，這就是汽蝕破壞，這種由于液體的汽化和凝結(jié)而產(chǎn)生的沖擊現(xiàn)象就稱為氣蝕現(xiàn)象。消除泵進(jìn)口氣蝕的措施有以下幾點： </p> <p> 提高泵的氣蝕性能水平，滿足現(xiàn)場裝置的氣蝕性能的要求。 </p> <p> 泵應(yīng)當(dāng)在低于允許吸液高度下操作，以保證整個裝置安全可靠的運轉(zhuǎn)。 </p> <p> 采用抗氣蝕材料制造葉輪，如：2Cr13、稀土合金鑄鐵、高鎳鉻合金材料等，比普通鑄鐵的抗氣蝕能力要好得多。 </p> <p> <br /> </p> <p> <br /> </p> </p>

<p> 給機封增加冷卻沖洗裝置。 </p> <p> 選擇耐高溫的材料，根據(jù)不同的工作溫度選用不同的材料。丁腈橡膠溫度上限為80℃，硅橡膠和氟橡膠為200℃，聚四氟乙烯為250℃。另外，機械密封中的非金屬摩擦副多采用石墨浸漬材料制成，所以也要根據(jù)不同的工作溫度選用不同種類的浸漬石墨。一般浸巴氏合金石墨適用溫度范圍小于150℃，浸樹脂石墨適用溫度范圍為170~200℃，浸銅、鋁、鉛的石墨可在小于400℃的工作條件下使用。動環(huán)組件應(yīng)盡可能選用膨脹系數(shù)相近的材料，以防止高溫下動環(huán)和動環(huán)座的連接松動。 </p> <p> 選擇金屬波紋管機械密封。金屬波紋管密封近年來在高溫密封中使用很多，并且取得了很好的效果。在該種機封中，金屬波紋管取代了普通機封中的彈簧，省去了動環(huán)輔助密封圈，不需要克服動環(huán)補償時與轉(zhuǎn)軸的摩擦和磨損，因此在高溫下使用，一般都能取得不錯的效果。 </p> <p> <br /> 浙江油泵密封可定制企業(yè)</p><p>
