這些細微的問題，只能在實踐中體會。2、新材料和新技術(shù)以上介紹的密封墊圈還很不全，況且密封技術(shù)正處于迅猛發(fā)展中。下面舉例介紹幾項新材料和新技術(shù)。（1）液體密封：隨著高分子有機合成工業(yè)的迅猛發(fā)展，出現(xiàn)了液態(tài)密封膠，使用于靜密封；這項新技術(shù)，通常叫做液體密封。液體密封的原理，是利用液態(tài)密封膠的粘附性、流動性和單分子膜效應(yīng)(越薄的膜自然回復(fù)傾向越大)，在適當壓力下，使它象墊圈一樣地起作用。所以對使用著的密封膠，也叫做液體墊圈。（2）聚四氟乙烯生料密封：聚四氟乙烯也是高分子有機化合物，它在燒結(jié)成制品之前，叫做生料，質(zhì)地柔軟，也有單分子膜效應(yīng)。用生料做成的帶叫生料帶，可以卷成盤長期保存。使用時能自由成形，任意接頭，只要一有壓力，便形成一個均勻地起著密封作用的環(huán)形膜。作為閥門中閥體與閥蓋間的墊圈，可在不取出閥瓣或閘板的情況下，撬開一縫隙，塞進生料帶去就行了。壓緊力小，不粘手，也不粘法蘭面，更換十分方便。對于榫槽法蘭適宜。聚四氟乙烯生料，還可做成管形和棒狀，作密封用。（3）金屬空心O形圈：彈性好，壓緊力小，有自緊作用，可選用多種金屬材料，從而在低溫、高溫和強腐蝕性介質(zhì)中都能適應(yīng)。。KQDP40-8S凱泉泵用機械密封。上海凱泉泵用機械密封KQWH50-100A</p><p

迷宮密封效果很好。但在實際應(yīng)用中，因此而產(chǎn)生的化工泵泄漏卻很多，所以在化工泵密封中不常用，分析其原因主要有：1、密封副(如軸和軸承壓蓋)配合間隙太大，而此間隙與密封效果成反比。配合面粗糙，明顯的螺旋狀車刀痕在有些情況下也加大了化工泵泄漏趨勢。2、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。3、油窗或油位計安裝位置有誤，誤導(dǎo)了人們對油室內(nèi)潤滑油量的正確判斷.4、運轉(zhuǎn)中油溫的升高使其粘度降低，增加了化工泵泄漏的可能。5、回油槽或回油孔尺寸偏小，或受到其它障礙，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度。所以，化工泵一般不采用此種密封方法?；け妹芊獾倪x擇化工泵經(jīng)常輸送的是具有腐蝕性，或是有毒揮發(fā)的介質(zhì)，因此其密封性能是衡量化工泵好與壞的標準之一。在選擇化工泵時，應(yīng)參考如下標準。1、密封形式有靜密封與動密封之分。對于靜密封，通常只采用密封圈和密封墊兩種密封形式，而在密封圈中又以O(shè)型圈的應(yīng)用性廣；對于動密封，很少采用填料密封。上海凱泉泵用機械密封KQWH50-100A</p></p><br
