有自密封作用，往往只用一個(gè)密封件便能完成密封； </p> <p> 密封性能較好，用作靜密封時(shí)幾乎可以做到?jīng)]有泄露； </p> <p> 運(yùn)動(dòng)摩擦阻力很小，對(duì)于壓力交變的場(chǎng)合也能適應(yīng)； </p> <p> 尺寸和溝槽已標(biāo)準(zhǔn)化，本錢(qián)低，便于使用和外購(gòu)。 </p><p> 水泵處理方法 </p> <p> 1 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(guò)緊。觀(guān)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(guò)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(kāi)后即復(fù)λ，有24MM的移動(dòng)距離即可。 </p> <p> 原因二、安裝過(guò)松。觀(guān)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，表面基本無(wú)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。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。因端面密封載荷的存在，在密封腔缺乏液體時(shí)啟動(dòng)泵而發(fā)生干摩擦。</p><div

style="text-indent:25px">橡膠是常用的密封材料。除橡膠外，適合于做密封材料的還有石墨等，聚四氟乙烯以及各種密封膠等。通用的橡膠密封制品材料通用的橡膠密封制品在**，化工，煤炭，石油，冶金，交通運(yùn)輸和機(jī)械制造產(chǎn)業(yè)等方面的應(yīng)用越來(lái)越廣為，已成為各種行業(yè)中的基礎(chǔ)件和配件。橡膠密封制品常用材料如下。丁腈橡膠丁腈橡膠具有優(yōu)良的耐燃料油及芳香溶劑等性能，但不耐酮，酯和氯化氫等介質(zhì)，因此耐油密封制品以及采用丁腈橡膠為主。氯丁橡膠氯丁橡膠具有良好的耐油和耐溶劑性能。它有較好的耐齒輪油和變壓器油性能，但不耐芳香族油。氯丁橡膠還具有優(yōu)良的耐天候老化和臭氧老化性能。氯丁橡膠的交聯(lián)斷裂溫度在200℃以上，通常用氯丁橡膠制作門(mén)窗密封條。氯丁橡膠對(duì)于無(wú)機(jī)酸也具有良好的耐腐蝕性。此外，由于氯丁橡膠還具有良好的撓曲性和不透氣性，可制成膜片和真空用的密封制品。自然橡膠自然橡膠與多數(shù)合成橡膠相比，具有良好的綜協(xié)力學(xué)性能，耐冷性，較高的回彈性及耐磨性。自然橡膠不耐礦物油，但在植物油和醇類(lèi)中較穩(wěn)定。在以正丁醇與精制蓖麻油混合液體組成的制動(dòng)液的液壓制動(dòng)系統(tǒng)中作為密封件的膠碗，膠圈均用自然橡膠制造，一般密封膠也常用自然橡膠制造。密封常用名稱(chēng)：密封圈、盤(pán)根、機(jī)械密封、油封、水封、盤(pán)根、密封墊板、密封膠、軟填料、液壓、氣動(dòng)密封件。南通泵用密封銷(xiāo)售廠(chǎng)家</p><p
