多級(jí)離心泵機(jī)械密封問題解析1、沒有輔助沖洗系統(tǒng)或輔助沖洗系統(tǒng)設(shè)置不合理多級(jí)離心泵機(jī)械密封的輔助沖洗系統(tǒng)是非常重要的，它可以有效地保護(hù)密封面，起到冷卻、潤(rùn)滑、沖走雜物等作用。有時(shí)設(shè)計(jì)員沒有合理地配置輔助沖洗系統(tǒng)，安德里茨機(jī)械密封，達(dá)不到密封效果；有時(shí)雖然設(shè)計(jì)人員設(shè)計(jì)了輔助系統(tǒng)，但由于沖洗液中有雜質(zhì)，沖洗液的流量、壓力不夠，沖洗口位置設(shè)計(jì)不合理等原因，也同樣達(dá)不到密封效果。2、振動(dòng)偏大機(jī)械密封振動(dòng)偏大，**終導(dǎo)致失去密封效果。但機(jī)械密封振動(dòng)偏大的原因往往不是機(jī)械密封本身的原因，多級(jí)離心泵的其它零部件是產(chǎn)生振動(dòng)的根源，如多級(jí)離心泵泵軸設(shè)計(jì)不合理、加工的原因、軸承精度不夠、聯(lián)軸器的平行度差，安德里茨機(jī)械密封、徑向力大等原因。3、多級(jí)離心泵汽蝕的原因由于裝置系統(tǒng)操作不合理以及工業(yè)多級(jí)鍋爐給水泵進(jìn)口汽蝕性能不好、泵的轉(zhuǎn)速偏高，在泵的入口處發(fā)生局部汽蝕，汽蝕發(fā)生后，水中會(huì)有氣泡，它一方面會(huì)沖擊機(jī)械密封面的外表面，使其表面出現(xiàn)破損；另一方面會(huì)使動(dòng)靜環(huán)的吻合面的流動(dòng)膜中也含有氣泡，不能形成穩(wěn)定的流動(dòng)膜，造成動(dòng)靜環(huán)的吻合面的干摩擦，使機(jī)械密封裝置損壞。4、機(jī)械加工精度不夠機(jī)械加工精度不夠，安德里茨機(jī)械密封，原因有很多，有的是機(jī)械密封本身的加工精度不夠。亳州橡膠波紋管機(jī)械密封件。安德里茨機(jī)械密封</p><div

若不垂直，油封的密封唇會(huì)把潤(rùn)滑油從軸上排干，也會(huì)導(dǎo)致密封唇的過度磨損。在運(yùn)轉(zhuǎn)中，殼體內(nèi)的潤(rùn)滑劑微微滲出一點(diǎn)，以達(dá)到在密封面處形成。五、骨架油封的作用一般就是將傳動(dòng)部件中需要潤(rùn)滑的部件與出力部件隔離，不至于讓潤(rùn)滑油滲漏，通常用于旋轉(zhuǎn)軸，是一種旋轉(zhuǎn)軸唇密封。骨架就如同混凝土構(gòu)件里面的鋼筋，起到加強(qiáng)的作用，并使油封能保持形狀及張力。按骨架型式可分為內(nèi)骨架油封，外骨架油封，內(nèi)外露骨架油封。骨架油封是采用質(zhì)量丁腈橡膠和鋼板制作而成，質(zhì)量穩(wěn)定，使用壽命長(zhǎng)。1、防止泥沙、灰塵、水氣等自外侵入軸承中；2、限制軸承中的潤(rùn)滑油漏出。對(duì)油封的要求是尺寸(內(nèi)徑、外徑和厚度)應(yīng)符合規(guī)定;要求有適當(dāng)?shù)膹椥?，能將軸適當(dāng)?shù)乜ㄗ。鸬矫芊庾饔?要耐熱、耐磨、強(qiáng)度好、耐介質(zhì)(油或水等)，使用壽命長(zhǎng)。六、油封的選擇油封的選擇要根據(jù)密封介質(zhì)和工作條件，密封介質(zhì)需要選擇油封的材料，工作條件主要考慮使用壓力、工作線速度、工作溫度范圍。選擇油封的材料時(shí)，必須考慮材料對(duì)工作介質(zhì)的相容性、對(duì)工作溫度范圍的適應(yīng)性和唇緣對(duì)旋轉(zhuǎn)軸高速旋轉(zhuǎn)時(shí)的跟隨能力。一般油封工作時(shí)其唇緣的溫度高于工作介質(zhì)溫度20~50℃，在選擇油封材料時(shí)應(yīng)予注意。CDL3-27

可防止意外的損壞。這些優(yōu)點(diǎn)也意味著可縮減密封的維修和更換時(shí)間。各種彈筒式密封幾乎都可以在市場(chǎng)上購(gòu)得，因此可以減少使用中出現(xiàn)的風(fēng)險(xiǎn)因素，而且還可以節(jié)約使用普通密封件所固有的維修時(shí)間。雙重密封和液體阻隔裝置采用雙重密封面的密封來代替單一的密封件具有更高程度的防漏特性。這類雙重密封大都應(yīng)用于揮發(fā)性強(qiáng)、有毒、易致*、危險(xiǎn)和潤(rùn)滑性很差的液體。雙重密封一般有三種設(shè)計(jì)型式，每種型式都要求在雙重密封面之間使用一種液體阻隔系統(tǒng)，以防止液體或氣體外泄。比較常用的低成本雙重密封是一種以背靠背方式安裝的密封，其旋轉(zhuǎn)密封面以相反的方向排列。它往往需要一種阻隔液體，其壓力應(yīng)高于填料盒壓力，大約為20psi，這樣就可保證內(nèi)部的密封始終能得到阻隔液體的潤(rùn)滑，而且也可保證密封面達(dá)到一定的密封壓力。圖5這類密封的旋轉(zhuǎn)面采用面對(duì)面方式進(jìn)行安裝，并采用高壓或低壓阻隔液體系統(tǒng)。在結(jié)構(gòu)比較復(fù)雜的面對(duì)面型式密封中，旋轉(zhuǎn)密封面之間是以面對(duì)面方式排列的(見圖5)，它們往往在同一靜止密封面的相反方向上動(dòng)作。這類密封既可采用高壓阻隔液體系統(tǒng)，也可采用低壓阻隔液體系統(tǒng)。第三種設(shè)計(jì)型式的密封采用串行式排列方式，即兩個(gè)旋轉(zhuǎn)密封面都離開葉輪。安德里茨機(jī)械密封</p><p
