氣體不會在泵的中部滯留·(5)無軸的彎曲問題，軸封可遠(yuǎn)離泵體，減少熱的影響。電機(jī)安裝架為遮風(fēng)結(jié)構(gòu)，所以電機(jī)的溫升對泵幾乎沒有影響。(6)泵殼埋于地下，易于保冷.所以，廈門205釜用機(jī)械密封件，石油液化氣用的低溫泵常用以上這種結(jié)構(gòu).2.低溫甲烷泵機(jī)械密封甲烷液化氣在-99℃時的蒸汽壓接近3MPa.乙烯裝置脫甲烷塔底泵在-53℃時出口壓力近似3MPa，采用雙端面串聯(lián)式機(jī)械密封，它是比拉公司BB81-K7+BB81B-S7型，尺寸為45x39與50x45(圖10-20)。耐腐蝕機(jī)械密封在腐蝕性介質(zhì)中，機(jī)械密封的零件受到介質(zhì)的強(qiáng)烈侵蝕，摩擦面同時受到.腐蝕和磨損，這種現(xiàn)象稱為“磨蝕“，其腐蝕速度約為無摩擦?xí)r的10~50倍.某些結(jié)構(gòu)材料具有優(yōu)良的耐蝕性能，耐磨性能卻較差;而另一些結(jié)構(gòu)材料雖具有良好的耐磨性，耐蝕性卻很差.因此，摩擦副應(yīng)選擇既要耐腐蝕又要耐磨，輔助密封圈、彈擠和結(jié)構(gòu)件也要有良好的耐蝕性能.在設(shè)計(jì)耐腐蝕機(jī)械密封時，一般采取以下一些措施:1.結(jié)構(gòu)上的隔離措施采用外裝式結(jié)構(gòu)，經(jīng)過適當(dāng)?shù)倪x擇，外裝式密封可以做到無金屬件與工藝介質(zhì)接觸，小的零件如彈簧，廈門205釜用機(jī)械密封件，廈門205釜用機(jī)械密封件、銷子可不受工藝介質(zhì)腐蝕.外裝式有普通型機(jī)械密封和波紋管型機(jī)械密封兩種，’以波紋管型密封結(jié)構(gòu)較好(圖10-21).如密封件材質(zhì)耐蝕能力許可。濰坊2009釜用機(jī)械密封件。廈門205釜用機(jī)械密封件</p><div

其缺點(diǎn)是有的波紋管彈力較小，需加輔助彈簧，如（圖8a）所示。集裝式機(jī)械密封是將普通的機(jī)械密封、軸套和密封壓蓋預(yù)先組合成一個整體，將其安裝到泵上后，不做任何調(diào)整（包括彈簧的壓縮量），只固定軸套和壓蓋，再把剖分式卡環(huán)取下（圖12中的A）即可投入使用。由此可見，卡環(huán)的（軸向）寬度等于彈簧的壓縮量，并且，從外部就可以知道該值的大小和變化情況。事先組裝，容易保證密封的安裝質(zhì)量，可減少因安裝不良引起的失效。近年來集裝式密封發(fā)展很快，因卡環(huán)的結(jié)構(gòu)、軸套與軸的傳動以及軸與軸套之間的密封等方面的不同，出現(xiàn)了許多種集裝式密封。三、國產(chǎn)104型機(jī)械密封國產(chǎn)104型機(jī)械密封為內(nèi)裝、內(nèi)流、單端面、單彈簧、非平衡型密封，輔助密封圈有V形和O形兩種型式（圖13）。3104型機(jī)械密封中的字母“B”表示平衡型密封，其余結(jié)構(gòu)和104型完全相同。B104型密封相當(dāng)于舊標(biāo)準(zhǔn)（JB1472－75）的110型(GY型)。兩種密封型式工作條件基本相同，*壓力不同。密封腔內(nèi)的溫度一20～80℃，轉(zhuǎn)速不大于3000r／min，介質(zhì)為清水、油類及其它弱腐蝕性液體。104型密封腔中的壓力為0～0．8MPa，而B104型適用壓力為0．6～3．0MPa。經(jīng)過二十多年的實(shí)踐，證明這兩種密封結(jié)構(gòu)簡單，使用可靠。因此。廈門205釜用機(jī)械密封件濰坊MR-D釜用機(jī)械密封件。</p><div

其抗拉強(qiáng)度和硬度增加而韌性下降.塑料和橡膠的低溫性能比金屬材料更為敏感.一般情況下，塑料和橡膠只能在-50℃以上的溫度范圍使用。對于低溫泵，資料[13]介紹:丁睛橡膠的使用溫度限為-60℃氯丁橡膠為-65℃，硅酮橡膠為-80℃，氟化橡膠為-45℃，聚四氟乙烯為-79℃，并認(rèn)為使用以上這些材料作填料的機(jī)械密封以-70℃為使用極限。如果介質(zhì)溫度在-70℃以下，則使用波紋管型機(jī)械密封或者雙端面機(jī)械密封.資料[6]介紹聚四氟乙烯在氦的沸點(diǎn)(℃)還能保持一點(diǎn)柔軟性，適宜做低溫材料，但聚四氟乙烯的膨脹系數(shù)大，所以在-50~-100℃溫度使用時，常采用四氟填充石墨或玻璃纖維，而不用純四氟材料.此外，在低溫時，V形圈裝到軸套上后，動環(huán)往往不能浮動。因此，要注意V形圈的組裝尺寸。關(guān)于低溫機(jī)械密封及低溫泵材料如表10-4所示。低溫時PTFE的機(jī)械性能如表10-5所示。2.結(jié)構(gòu)要求在一般的0~-50℃低溫下，常采用單端面機(jī)械密封，有非平衡或平衡型結(jié)構(gòu)，但多數(shù)選用平衡型結(jié)構(gòu)，這是因?yàn)槊芊舛嗣娴囊盒萁?jīng)摩擦后溫度升高，液膜壓力隨之升高而將密封面推開，泄漏加劇。因此，低溫時的端面比壓要選高值。在液溫低于-70℃時，則采用波紋管密封或雙端面密封.不過使用雙端面密封時。威海MR-D釜用機(jī)械密封件。廈門205釜用機(jī)械密封件</p><p
