機械密封處滲水的第一種可能性是機封的動、靜環(huán)平面磨損。而造成機封的動、靜環(huán)平面磨損的原因有六個方面： </p> <p> 原因一、安裝過緊。觀察機械密封的動靜環(huán)平面，如有嚴重燒焦現(xiàn)象，平面發(fā)黑和很深的痕跡，密封橡膠變硬，失去彈性，這種現(xiàn)象是由于安裝過緊造成的。 </p> <p> 處理辦法：調(diào)整安裝高度，葉輪發(fā)裝后，南京填料密封哪家比較好，用螺絲刀拔動彈簧，南京填料密封哪家比較好，彈簧有較強的張力，松開后即復λ，有24MM的移動距離即可。 </p> <p> 原因二、安裝過松。觀察機封動、靜環(huán)平面，其表面有一層很薄的水垢，能夠擦去，表面基本無磨損，這是彈簧失去彈性及裝配不良造成，或電機軸向竄動造成。 </p> <p> 原因三，南京填料密封哪家比較好、水質(zhì)差含顆粒。由于水質(zhì)差，含有小顆粒及介質(zhì)中鹽酸鹽含量高，形成磨料磨損機封的平面或拉傷表面產(chǎn)生溝槽、環(huán)溝等現(xiàn)象。 </p> <p> 處理辦法：改進水壓或介質(zhì)，更換機封。 </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="南京填料密封哪家比較好" src="https://tyunfile.71360.com/UploadFile/lscmjx/637245505726044921/5036182.jpg"></div><p> 提高化工機械效果的措施1運行平穩(wěn)。當工廠運行日趨穩(wěn)定時，即很少有停車、啟動和運行條件的變化，正常的操作程序為泵的運轉(zhuǎn)提供了良好運行的環(huán)境，化工機械減少了在惡劣的動態(tài)工況下的損壞以及突然停車造成的瞬間破壞的可能，因而密封壽命較大增長。2連續(xù)沖洗。沖洗包括工作介質(zhì)的自沖洗和相對潔凈的工藝液沖洗，沖洗介質(zhì)不符合設(shè)計要求是造成化工機械泄漏的重要原因。一方面通過有針對性的檢查、調(diào)整，使沖洗介質(zhì)的壓力、流量、溫度都符合設(shè)計要求；另一方面通過定期清理沖洗液過濾器及合理增加沖洗管道上的止逆閥，從根本上避免了沖洗原因造成的密封損壞。設(shè)備改良。在運行中不斷總結(jié)經(jīng)驗，通過技術(shù)改造使機泵等設(shè)備的機械性能得以保證。例如：DA302塔循環(huán)水泵更換化工機械后，頻繁出現(xiàn)瞬時密封損壞。究其原因是泵殼密封環(huán)和葉輪口環(huán)間間隙不足產(chǎn)生摩擦造，這種摩擦產(chǎn)生的不規(guī)則運動使泵振動導致密封損壞。經(jīng)過加工使口環(huán)配合間隙達到，在不影響泵的使用性能的前提下，使這一問題得到了**終的解決。

碳化硅有反應(yīng)燒結(jié)碳化硅、常壓燒結(jié)碳化硅和熱壓碳化硅。 </p> <p> 硬質(zhì)合金。硬質(zhì)合金主要是碳化鎢WC，分別有鈷基碳化鎢WC-Co、鎳基碳化鎢WC-Ni和鈷-鎳基碳化鎢WC-Co-Ni。碳化鎢的特點：硬度高，耐磨性好；機械強度高，抗彎性好；導熱率較高而膨脹系數(shù)較小，密封面摩擦熱容易導出；無鈷硬質(zhì)合金耐腐蝕性較好。 </p> <p> <p> 作為輔助密封圈的材料有橡膠、塑料、石棉、膨脹石墨、石墨和金屬脹圈等。橡膠圈是使用**廣的一種輔助密封圈。常用的橡膠密封圈材料有丁腈橡膠、氟橡膠、硅橡膠、氯丁橡膠、丁苯橡膠等。 </p> <p> 丁腈橡膠是常用的一種耐油橡膠。它是丁二烯和丙烯腈的共聚物。根據(jù)丙烯腈含量多少分成若干種：低丙烯腈（丁腈-18）、中丙烯腈（丁腈-26）和高丙烯腈（丁腈-40）、丙烯腈含量越高，它的耐油性越好，抗張強度、硬度和耐磨性、耐水性增加，透氣性減小。隨之而來，它在極性溶劑中是溶解度卻增大，耐腐蝕性也受到影響，彈性和耐寒性也變差。丁腈橡膠不耐撓曲，抗撕裂也較差。 </p> </p><div
