100多年來，人們采用填料一類的多種密封材料，使液體從液泵殼體沿著主軸的向外泄漏量不斷減少。盡管現(xiàn)代工藝流程中采用的液泵，仍然較大程度地沿用**古老的密封設計——填料盒，因為其起步費用低，而且又為工廠的工作人員所熟悉。 </p> <p> 然而，由于環(huán)境問題的關系，采用填料密封的方法已逐漸不能被人們所接受，特別是針對現(xiàn)代工藝流程中比較普遍的、腐蝕性較強的液體而言。因此，在實際應用中，以機械密封代替填料密封的情況越來越多。 </p> <p> <br /> 江蘇油泵密封的用途和特點機械密封按工作條件和介質性質的不同，有耐高溫、耐低溫機械密封，耐高壓、耐腐蝕機械密封等。</p><div

潛污泵的作用是將污水中的雜質通過的方式處理。然后排放掉，與清水泵的不同之處使其技術要求也不同于普通類型的設備，它的設計需要考慮到效率、磨損以及特殊環(huán)境：（1）導板等部件自動與著脫耦合，耦合牢固可靠。（2）引出電纜應采用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：葉輪設計成無堵塞型式，葉輪皆經(jīng)過靜平衡試驗。葉輪材質為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）主軸材質選用3Cr13經(jīng)調質處理，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，造成葉輪松脫。（5）密封環(huán)：材質鑄造青銅，防止因銹蝕而與葉輪咬死。設有密封環(huán)可更大限度地減少內部泄露，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。 </p> <p> <br /> </p><p> 泵用機械密封是精密的部件，制造精度及安裝精度要求都很嚴格，如果裝配不當就會影響密封性能，要正確安裝必須注意以下幾點： </p> <p> 泵用機械密封的冷卻和沖洗 </p> <p> 第一種冷卻形式由水泵的出口或高壓端，將輸送的干凈介質，直接沖洗密封端面，然后進入泵腔內，通過介質的不斷循環(huán)，將磨擦端面的的磨擦熱帶走達到冷卻的效果。 </p> <p> 第二種冷卻方式在第一種冷卻形式的基礎上在靜環(huán)的背部增加一冷卻水套，冷卻效果有所改善，并可以沖洗，收集泄露出來的液體。當密封介質溫度＞150℃時除了在冷卻水套中通過冷卻水及靜環(huán)背部冷卻外，應采取強制冷卻措施。即從泵出口的干凈介質應預先經(jīng)熱交換器冷卻至50℃時。再進入密封腔冷卻沖洗，該形式是冷卻效果**良好的一種。 </p> <p> 如介質中含有顆粒或雜質，必須采用過濾措施，把常溫干凈沖洗液輸入密封腔內。因端面密封載荷的存在，在密封腔缺乏液體時啟動泵而發(fā)生干摩擦。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="江蘇油泵密封的用途和特點,封"

機械密封裝配前的檢查有哪些內容？答：一般性檢查：主要檢查個零件的型號、規(guī)格、性能、配合尺寸及有無缺口、點坑、變形和裂紋等損傷。動、靜環(huán)的檢查：密封端面要光潔明亮、物崩邊、點坑、溝槽、劃痕等缺點。對石墨環(huán)，還要浸沒有檢查是否有裂紋。 </p> <p> .機械密封彈簧的檢查都包括哪些內容？答：彈簧的檢查包括：總圈數(shù)、有效圈數(shù)、自由高度、軸心對端面是否垂直、彈簧旋向。但彈簧必須檢查旋向，多彈簧不需要檢查旋向。新彈簧要檢查其原始自由高度，自由高度要測量，并與原始記錄比較，殘余變形過大的要更換掉。舊彈簧清洗干凈后，要測量其彈力，彈力減少20%的要更換掉。多彈簧機械密封，各彈簧自由高度差不得小于0.5mm。在使用單彈簧的機械密封時，忽略彈簧的旋轉方向與泵轉子轉動方向的正確組合也時有發(fā)生。江蘇清水密封市場批發(fā)價格</p><p

在新增的水泵中全部采用了機械密封，與原有水泵的盤根密封形成了鮮明的對比：（1）機械密封與盤根密封在密封性能上，機械密封要比盤根密封漏泄量小的多，*為盤根密封漏泄量的1%。（2）使用壽命長，兩年以內無需更換，以往盤根密封每60天左右就要進行一次更換。（3）消耗功率較少同比盤根密封省電5%以上。（4）減少了軸或軸承的磨損。 </p> <p> 通過摸索對比先后將車間的兩臺循環(huán)水泵、兩臺射水泵、凝結水泵共6臺泵進行了進行密封改造。改造后均收到了良好的效果。 </p> <p> 循環(huán)水泵（20HBA）在未改為機械密封前，每年至少要更換4次油盤根，每次更換量在1公斤左右，市場價格30元.，由于盤根磨損所致3年左右需更換一根水泵軸及配套軸瓦，費用在7000元左右，不計人工費用每臺水泵每年消耗在2500元左右。而改為機械密封后費用方面每臺泵的機械密封價格在600元左右，至少一個大修期在3年以上，由于摩擦阻力的降低使電耗每小時下降8度，全年節(jié)電在58000度，降低成本3萬元左右。因此機械密封于盤根密封相比優(yōu)勢十分明顯。
