防止工作介質(zhì)從泵內(nèi)泄漏出來(lái)或者防止外界雜質(zhì)或空氣侵入到泵內(nèi)部的裝置或措施稱(chēng)為密封，被密封的介質(zhì)一般為液體、氣體或粉塵。泵的密封裝置主要分兩類(lèi)：一類(lèi)為靜密封，一類(lèi)為動(dòng)密封。靜密封通常有墊片密封，黑河泵用機(jī)械密封型號(hào)、O型圈密封、螺紋密封等型式。動(dòng)密封則主要有軟填料密封，黑河泵用機(jī)械密封型號(hào)、油封密封、迷宮密封、螺旋密封、動(dòng)力密封和機(jī)械密封等。造成泄漏的原因主要有兩個(gè)方面：一是密封面上有間隙。二是密封部位兩側(cè)存在壓力差，消除或減小任何一個(gè)因素都可以阻止或減小泄漏，達(dá)到密封的目的。泵的設(shè)計(jì)壓力和使用壓力是客觀存在不能減小，所以泵的密封該解決的是消除或減小密封面之間的間隙。這種間隙包括密封面之間的間隙和密封裝置本生內(nèi)部的間隙。機(jī)械密封機(jī)械密封是現(xiàn)代泵軸封的主要方法，雖然利用它實(shí)現(xiàn)完全不泄漏不大容易，但是達(dá)到微小的，令人完全可以接受的泄漏量卻是完全可能的。但在泵的運(yùn)行中卻經(jīng)常出現(xiàn)令人尷尬的局面，那么機(jī)械密封失效的原因是什么呢?1、械密封的材質(zhì)選擇不合適。機(jī)械密封的材質(zhì)與所輸送的介質(zhì)不相匹配。在工作時(shí)，黑河泵用機(jī)械密封型號(hào)，密封元件很快被腐蝕，溶解或磨損，因而失去密封能力。所以根據(jù)輸送介質(zhì)的性質(zhì)而選擇機(jī)械密封的材質(zhì)是保證其密封功能和正常壽命的先決條件。天水水泵用機(jī)械密封選型。黑河泵用機(jī)械密封型號(hào)</p><div

***節(jié)機(jī)械密封原理機(jī)械密封是一種旋轉(zhuǎn)機(jī)械的軸封裝置。比如離心泵、離心機(jī)、反應(yīng)釜和壓縮機(jī)等設(shè)備。由于傳動(dòng)軸貫穿在設(shè)備內(nèi)外，這樣，軸與設(shè)備之間存在一個(gè)圓周間隙，設(shè)備中的介質(zhì)通過(guò)該間隙向外泄漏，如果設(shè)備內(nèi)壓力低于大氣壓，則空氣向設(shè)備內(nèi)泄漏，因此必須有一個(gè)阻止泄漏的軸封裝置。軸封的種類(lèi)很多，由于機(jī)械密封具有泄漏量少和壽命長(zhǎng)等優(yōu)點(diǎn)，所以當(dāng)今世界上機(jī)械密封是這些設(shè)備主要的軸密封方式。機(jī)械密封又叫端面密封，在國(guó)家有關(guān)標(biāo)準(zhǔn)中是這樣定義的：“由至少一對(duì)垂直于旋轉(zhuǎn)軸線的端面在流體壓力和補(bǔ)償機(jī)構(gòu)彈力（或磁力）的作用以及輔助密封的配合下保持貼合并相對(duì)滑動(dòng)而構(gòu)成的防止流體泄漏的裝置。”一、機(jī)械密封的分類(lèi)機(jī)械密封近年來(lái)發(fā)展很快，根據(jù)不同的工況出現(xiàn)了各種各樣的結(jié)構(gòu)，但無(wú)論哪種結(jié)構(gòu)都由以下四部分組成：一部分是由動(dòng)環(huán)和靜環(huán)組成的密封端面，有時(shí)也稱(chēng)為摩擦副。第二部分是由彈性元件為主要零件組成的緩沖補(bǔ)償機(jī)構(gòu)，其作用是使密封端面緊密貼合。第三部分是輔助密封圈，其中有動(dòng)環(huán)和靜環(huán)密封圈。第四部分是使動(dòng)環(huán)隨軸旋轉(zhuǎn)的傳動(dòng)機(jī)構(gòu)。機(jī)械密封實(shí)現(xiàn)的原理如圖所示：軸通過(guò)傳動(dòng)座（6）和推環(huán)（4），帶動(dòng)動(dòng)環(huán)（2）旋轉(zhuǎn)，靜環(huán)(1)固定不動(dòng)。</p><p>

②渦輪式攪拌器由在水平圓盤(pán)上安裝2～4片平直的或彎曲的葉片所構(gòu)成。槳葉的外徑、寬度與高度的比例，一般為20：5：4，圓周速度一般為3～8m/s。渦輪在旋轉(zhuǎn)時(shí)造成高度湍動(dòng)的徑向流動(dòng)，適用于氣體及不互溶液體的分散和液液相反應(yīng)過(guò)程。被攪拌液體的粘度一般不超過(guò)25Pa·s。③槳式攪拌器有平槳式和斜槳式兩種。平槳式攪拌器由兩片平直槳葉構(gòu)成。槳葉直徑與高度之比為4～10，圓周速度為～3m/s，所產(chǎn)生的徑向液流速度較小。斜槳式攪拌器的兩葉相反折轉(zhuǎn)45°或60°，因而產(chǎn)生軸向液流。槳式攪拌器結(jié)構(gòu)簡(jiǎn)單，常用于低粘度液體的混合以及固體微粒的溶解和懸浮。④錨式攪拌器槳葉外緣形狀與攪拌槽內(nèi)壁要一致，其間*有很小間隙，可消除附在槽壁上的粘性反應(yīng)產(chǎn)物或堆積于槽底的固體物，保持較好的傳熱效果。槳葉外緣的圓周速度為～200Pa·s的牛頓型流體和擬塑性流體(見(jiàn)粘性流體流動(dòng)。唯攪拌高粘度液體時(shí)，液層中有較大的停滯區(qū)。⑤螺帶式攪拌器螺帶的外徑與螺距相等,專(zhuān)門(mén)用于攪拌高粘度液體(200～500Pa·s)及擬塑性流體，通常在層流狀態(tài)下操作。⑥磁力攪拌器Corning數(shù)字式加熱器帶有一個(gè)閉路旋鈕來(lái)監(jiān)控與調(diào)節(jié)攪拌速度。微處理器自動(dòng)調(diào)節(jié)馬達(dá)動(dòng)力去適應(yīng)水質(zhì)、粘性溶液與半固體溶液。黑河泵用機(jī)械密封型號(hào)</p><p
