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。 </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，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。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。 </p> <p> 原因四、缺水運(yùn)行造成干磨損壞。此現(xiàn)象多見于底閥式安裝形式進(jìn)口處負(fù)壓，進(jìn)水管有空氣，泵腔內(nèi)有空氣，泵開機(jī)后，機(jī)封的磨擦高速運(yùn)轉(zhuǎn)時(shí)產(chǎn)生高溫，南通管道泵密封制造廠家，無法得到冷卻，南通管道泵密封制造廠家，檢查機(jī)封，彈簧張力正常，南通管道泵密封制造廠家，摩擦面燒焦發(fā)黑，橡膠變硬開裂。處理辦法：排盡管道及泵腔內(nèi)空氣，更換機(jī)械密封。

為了不因選用串聯(lián)密封而增加成本，又能使高溫?zé)崴冒踩煽窟\(yùn)行，建議選用單端面機(jī)械密封，沖洗方案可以選擇PLAN23+62。PLAN62 所通急冷液直接從23 冷卻器后引旁路連接至密封急冷口，具體流程見圖3 所示。可以看出，通過此種布置方式， PLAN62 不需要額外的配管將循環(huán)水引入密封急冷口，又能起到在密封失效時(shí)降低介質(zhì)溫度，從而避免對(duì)人員的傷害，對(duì)系統(tǒng)加以保護(hù)。 </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

主軸的軸向和徑向運(yùn)動(dòng)需要與彈簧之間保持一定的靈活性，以保證接觸面之間的密封。然而，只能提供一定程度的靈活性。液泵的機(jī)械狀況及其長(zhǎng)度直徑比(一種主軸的直徑與其延伸長(zhǎng)度之比的衡量方式，比值越低越好)對(duì)密封的可靠性起著重要的作用。密封的靈活性一般由一個(gè)大型主彈簧和一系列小彈簧或波紋密封裝置提供保證。 </p> <p> <span style="font-size:12px;">化學(xué)工業(yè)所采用的傳統(tǒng)密封設(shè)計(jì)，其密封壓力施加于旋轉(zhuǎn)面上，這種密封稱之為旋轉(zhuǎn)密封，因?yàn)閺椈苫虿y密封裝置與主軸一起旋轉(zhuǎn)。比較新穎的設(shè)計(jì)，其彈簧或波紋密封裝置安裝于靜止面上。在現(xiàn)在的機(jī)械密封上，上述兩種密封方式都有非常普遍的應(yīng)用，這樣對(duì)于安裝具有一定的靈活性。</span> </p> <p> <span style="font-size:12px;">早期設(shè)計(jì)的許多機(jī)械密封采用單一的大型彈簧圍繞主軸排列，在液泵起動(dòng)過程中，可為密封面提供很強(qiáng)的密封力。密封的作用依靠主軸的旋轉(zhuǎn)來繃緊彈簧卷。</span> </p></p><br /><p>文章來源地址:
