機(jī)械密封處滲水的第一種可能性是機(jī)封的動(dòng)、靜環(huán)平面磨損。而造成機(jī)封的動(dòng)、靜環(huán)平面磨損的原因有六個(gè)方面： </p> <p> 原因一、安裝過緊。觀察機(jī)械密封的動(dòng)靜環(huán)平面，如有嚴(yán)重?zé)宫F(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，用螺絲刀拔動(dòng)彈簧，彈簧有較強(qiáng)的張力，松開后即復(fù)λ，有24MM的移動(dòng)距離即可，蘇州液壓密封廠家批發(fā)。 </p> <p> 原因二、安裝過松。觀察機(jī)封動(dòng)、靜環(huán)平面，其表面有一層很薄的水垢，能夠擦去，蘇州液壓密封廠家批發(fā)，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(jī)軸向竄動(dòng)造成。 </p> <p> 原因三、水質(zhì)差含顆粒，蘇州液壓密封廠家批發(fā)。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(jī)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(jìn)水壓或介質(zhì)，更換機(jī)封。根據(jù)工作速度，確定采用旋轉(zhuǎn)式或靜止式，流體動(dòng)壓式或非接觸型。蘇州液壓密封廠家批發(fā)</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="text-indent:25px">目前，污水泵產(chǎn)品常用的密封形式有兩種:填料密封和機(jī)械密封。填料密封，如圖1所示，是古老的一種密封結(jié)構(gòu)，發(fā)源于工業(yè)**之前的傳統(tǒng)密封裝置，有著100年的材料工藝、潤(rùn)滑劑系統(tǒng)和制造方法，并保持持續(xù)進(jìn)步，目前很多的應(yīng)用場(chǎng)合。經(jīng)分析，該軟填料密封結(jié)構(gòu)存在如下缺點(diǎn):1.密封介質(zhì)含有的雜質(zhì)嚴(yán)重影響密封性能。雜質(zhì)進(jìn)入軟填料密封內(nèi)部，進(jìn)一步增大了填料密封和軸套之間的摩擦、磨損。雖然材料耐磨性較好，但是使用效果仍然不佳，泄漏頻繁。另外由于沒有采用封液對(duì)填料密封進(jìn)行潤(rùn)滑冷卻，也加劇了填料與軸套之間的磨損。2.工作狀態(tài)不穩(wěn)定需頻繁調(diào)整和更換填料。由于軟填料自身具有的粘彈特性，在工作狀態(tài)下會(huì)出現(xiàn)明顯的應(yīng)力松弛。為保持其正常的密封功能，需不斷地通過壓緊壓蓋來增大填料與軸的徑向接觸力，同時(shí)也增大了軟填料與軸的磨損，因此不得不經(jīng)常更換(或添加)填料，維修工作量和費(fèi)用較大增加。3.磨損嚴(yán)重致使能耗量大。根據(jù)軟填料密封的工作機(jī)理，填料密封與軸(或軸套)之間必須保持較大的徑向接觸壓力以維持密封，因此填料和軸(或軸套)的摩擦、磨損都很嚴(yán)重，在密封很快失去工作能力的同時(shí)，造成相當(dāng)大的能耗浪費(fèi)。蘇州機(jī)械液壓密封廠家批發(fā)密封常用名稱：密封圈、盤根、機(jī)械密封、油封、水封、盤根、密封墊板、密封膠、軟填料、液壓、氣動(dòng)密封件。</p><div

1、如果更換新機(jī)封，須檢查機(jī)械密封的型號(hào)、規(guī)格是否正確，質(zhì)量是否符合標(biāo)準(zhǔn)； </p> <p> 2、靜環(huán)尾部防轉(zhuǎn)槽端與防轉(zhuǎn)銷頂部應(yīng)保持1mm-2mm的軸向間隙，以免緩沖失效； </p> <p> 3、動(dòng)、靜環(huán)端面用酒精清洗干凈，其余金屬件用汽油清洗并用潔凈的壓縮空氣吹干，仔細(xì)檢查務(wù)心保證動(dòng)、靜環(huán)密封面沒有任何損傷。裝配前，兩件“0”形橡膠密封圈應(yīng)涂上一層潤(rùn)滑油膏，動(dòng)、靜環(huán)端面不許涂油。 </p> <p> 機(jī)械密封的安裝 </p> <p> 機(jī)封安裝順序及注意事項(xiàng)如下： </p> <p> 1、在轉(zhuǎn)子與泵體的相對(duì)位置固定之后，確定機(jī)械密封的安裝位置，根據(jù)密封的安裝尺寸及靜環(huán)在壓蓋中的位置，測(cè)算出密封在軸或軸套上的定位尺寸； </p> <p> 2、安裝機(jī)封動(dòng)環(huán)，動(dòng)環(huán)安裝后須保證能其在軸上靈活移動(dòng)； </p> <p> 3、將組裝好的靜環(huán)部分和動(dòng)環(huán)部分組裝好； </p> <p> 4、把密封端蓋裝在密封體內(nèi)，并將螺絲擰緊。 </p><p style="text-indent:25px">化學(xué)腐蝕由于密封接觸腐蝕性介質(zhì)就會(huì)產(chǎn)生表面腐蝕，甚至在表面各處產(chǎn)生劇烈腐蝕點(diǎn)而形成點(diǎn)蝕。在金屬的晶界上產(chǎn)生的晶間腐蝕，會(huì)深入到金屬的內(nèi)部，并進(jìn)一步破壞而引起斷裂。腐蝕的性能影響很大。由于密封件比主機(jī)的零件小，而且更精密，通常要選用比主機(jī)更耐腐蝕的材料。經(jīng)驗(yàn)表明，壓力、溫度和滑動(dòng)速度都能使腐蝕加速。密封件的腐蝕率隨溫度升高呈指標(biāo)規(guī)律增加。處理強(qiáng)腐蝕流體時(shí)，采用雙端面密封，可以比較大限度減輕腐蝕對(duì)密封件的影響，因?yàn)樗c工藝流體相接觸的零件數(shù)量少。這也是在強(qiáng)腐蝕條件下，選擇密封結(jié)構(gòu)的一條重要的原則。密封零件失效機(jī)械密封零件失效大部分是輔助密封圈失效，機(jī)械密封由于泄漏而不能正常工作的一個(gè)主要原因也是因?yàn)镺形圈失效引起的。O形圈失效的表現(xiàn)為老化、長(zhǎng)久性變形、溶脹變形、扭曲及擠出損傷。因此，在選用O形圈時(shí)應(yīng)考慮合成橡膠的安全使用溫度，盡可能地選用截面較大的橡膠O形圈，適當(dāng)提高硬度，采用溝槽式的裝配結(jié)構(gòu)，通過沉浸試驗(yàn)合理選材，必要時(shí)選用復(fù)合材料，如橡膠包覆聚四氟乙烯密封圈。人們?cè)诜治鰴C(jī)械密封泄漏原因時(shí)，在機(jī)械封自身方面查找原因，比如：它的選型如是否合適，材料選擇是否正確。</p><div

用增塑劑分散的聚氯乙烯樹脂和含有瀝青的橡膠并用的密封膠是兩個(gè)不同類型的熱轉(zhuǎn)變體系。乙烯基樹脂增塑體在室溫下是液態(tài)懸浮體，通過加熱轉(zhuǎn)化為固體而硬化；而橡膠——瀝青并用密封膠則為熱熔性的。 </p> <p> 氧化硬化型密封膠 </p> <p> 表面干燥的嵌縫或安裝玻璃用密封膠屬這種類型，主要以干性和半干性植物油為基材。油料可以是精制聚合的、吹制的或化學(xué)改性的。用環(huán)烷酸鈷作催干劑加速表面干燥而內(nèi)部不硬化；環(huán)烷酸鉛可使表面和內(nèi)部都硬化；而環(huán)烷酸錳使內(nèi)部硬化更有效。
