機(jī)械密封在電廠水泵中的應(yīng)用改造 </p> <p> <p> 在新增的水泵中全部采用了機(jī)械密封，與原有水泵的盤根密封形成了鮮明的對比：（1）機(jī)械密封與盤根密封在密封性能上，機(jī)械密封要比盤根密封漏泄量小的多，*為盤根密封漏泄量的1%。（2）使用壽命長，兩年以內(nèi)無需更換，以往盤根密封每60天左右就要進(jìn)行一次更換。（3）消耗功率較少同比盤根密封省電5%以上。（4）減少了軸或軸承的磨損。 </p> <p> 通過摸索對比先后將車間的兩臺循環(huán)水泵、兩臺射水泵、凝結(jié)水泵共6臺泵進(jìn)行了進(jìn)行密封改造。改造后均收到了良好的效果。 </p> <p> 循環(huán)水泵（20HBA）在未改為機(jī)械密封前，每年至少要更換4次油盤根，每次更換量在1公斤左右，市場價格30元.，由于盤根磨損所致3年左右需更換一根水泵軸及配套軸瓦，費(fèi)用在7000元左右，不計人工費(fèi)用每臺水泵每年消耗在2500元左右。而改為機(jī)械密封后費(fèi)用方面每臺泵的機(jī)械密封價格在600元左右，至少一個大修期在3年以上，由于摩擦阻力的降低使電耗每小時下降8度，全年節(jié)電在58000度，降低成本3萬元左右。因此機(jī)械密封于盤根密封相比優(yōu)勢十分明顯。 </p> <p> <br /> </p> <p> <br /> </p> 蘇州污水密封軸彎曲變形時橫截面形心沿與軸線垂直方向的線位移稱為撓度，機(jī)械密封要求兩個密封端面之間受力均勻。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="font-size:12px;">軸的表面線速度：在同一直徑條件下，不同材料制造的油封，適應(yīng)軸面旋轉(zhuǎn)線速度的能力不同，其關(guān)系如下圖所示。油封使用的線速度范圍一般小于15m/s, 滿意的潤滑和良好的散熱條件才是決定性因素。相應(yīng)較低的數(shù)據(jù)，適用于更為苛刻的條件。 </span> </p> <p> <span style="font-size:12px;">溫度：由于旋轉(zhuǎn)軸表面與油封的密封唇部產(chǎn)生摩擦，所以密封唇口部的溫度高于油液中的溫度，一般油封工作時其唇緣的溫度高于工作介質(zhì)溫度20~50℃。隨著轉(zhuǎn)速增高，壓力增加密封唇口處的溫度也隨之上升。另外，帶有防塵唇的油封，比無防塵唇的油封會出現(xiàn)高于20℃的過高溫度。當(dāng)超過容許溫度時會縮短油封的工作壽命，造成密封唇過早長久性硬化，以及磨損加大。油封的工作溫度范圍與油封使用的材料有關(guān)：材料為丁晴橡膠（NBR）時為-40~120℃，亞力克橡膠（ACM）-30~180℃，氟橡膠（FPM）-25~300℃。</span> </p> <p> <span style="font-size:12px;">壓力：油封主要用于無壓或者在微壓的條件下使用，比較大工作壓力0.02～0.05Mpa。當(dāng)工作壓力超過這個值時應(yīng)選用耐壓型油封。</span> </p> <p> <br /> </p><p> 離心泵口環(huán)一般指葉輪口環(huán)，是安裝在水泵葉輪和泵體之間的一個環(huán)狀金屬圈， </p> <p> <span style="font-size:12px;"> 口環(huán)，也叫耐磨環(huán)。其主要作用是防止出口端介質(zhì)倒流回進(jìn)口端介質(zhì)也就是密封作用（因此有“密封環(huán)”這一名稱）；同時也起耐磨作用，避免葉輪和泵殼直接接觸損壞，有保護(hù)葉輪的作用（因此有“耐磨環(huán)”這一名稱）。</span> </p> <p> <span style="font-size:12px;">離心泵口環(huán)，一般水泵的級數(shù)與口環(huán)的數(shù)量是一樣的，也就是說一個5級的水泵，那么口環(huán)也就有5個，一個首口環(huán)，4個口環(huán)。</span> </p> <p> <span style="font-size:12px;">多級離心泵口環(huán)的作用是在葉輪與泵殼間形成狹窄、曲折的通道，來增加介質(zhì)的流動阻力，達(dá)到減少介質(zhì)泄漏的目的。離心泵口環(huán)的設(shè)置還起到保護(hù)泵上主要零件不受磨損的作用(公眾號:泵管家)，在口環(huán)磨損后，可以修復(fù)或更換新環(huán)、恢復(fù)正常裝配間隙，這樣既經(jīng)濟(jì)又便于檢修。</span> </p> <p> <span style="font-size:12px;">口環(huán)間隙大會將低泵的使用效率，經(jīng)過泵加壓的流體會過多的從泵出口區(qū)域沿葉輪與口環(huán)的間隙返回到進(jìn)口，從而降低了泵的使用效率，同時由于流量的加大，會使口環(huán)過早的被磨損。口環(huán)間隙過大，會導(dǎo)致泵的流量降低，嚴(yán)重時不上量。 </span> </p> <p> <span style="font-size:12px;">離心泵口環(huán)的完好性及它與葉輪問徑向間隙含，在拆卸泵時應(yīng)首先檢查。如離心泵口環(huán)已有溝槽等缺損或已破裂或間隙艿超過表5中所規(guī)定的數(shù)值時，應(yīng)更換新口環(huán)或?qū)⒃诃h(huán)補(bǔ)焊修復(fù)。</span> </p> <p> <br /> </p> <p> <br /> 機(jī)械密封的正常運(yùn)行必須具備以下條件：機(jī)械密封的泵軸撓度要小，加上機(jī)械密封自身性能，才能達(dá)到密封效果。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

泵機(jī)械密封©水的故障是水泵故障中**容易出現(xiàn)的故障之一，所以水泵機(jī)械密封也屬于水泵部件中比較關(guān)鍵的易損件之一，水泵選型時機(jī)械密封材質(zhì)一定要能適合用戶輸送的液體介質(zhì)。 </p> <p> <p> 步驟/方法 </p> <p> 機(jī)械密封處滲©水的第一種可能性是機(jī)封的動、靜環(huán)平面磨損。而造成機(jī)封的動、靜環(huán)平面磨損的原因有六個方面：安裝過緊。觀察機(jī)械密封的動靜環(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。處理辦法：調(diào)整安裝高度，葉輪安裝后，用螺絲刀拔動彈簧，彈簧有較強(qiáng)的張力，松開后即復(fù)λ，有2-4MM的移動距離即可。安裝過松。觀察機(jī)封動、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)軸向竄動造成。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。處理辦法：改進(jìn)水壓或介質(zhì)，更換機(jī)封。缺水運(yùn)行造成干磨損壞。 </p> <p> <br /> </p> 泵在停一段時間后再啟動時泄漏，因為摩擦副附近介質(zhì)的凝固、結(jié)晶，摩擦副上有水垢、彈簧腐蝕、阻塞而失彈。蘇州污水密封</p><p style="text-indent:25px">機(jī)械密封的正常運(yùn)行必須具備以下條件：泵軸的竄量不能太大。蘇州污水密封</p><p> 強(qiáng)酸強(qiáng)堿介質(zhì)具有較強(qiáng)的腐蝕性，且易結(jié)晶，為了防止介質(zhì)對密封彈性元件的腐蝕，應(yīng)使彈性元件與介質(zhì)隔離，采用外裝結(jié)構(gòu)，第3 種布置方式(背靠背或面對面)。O 形圈材料選用耐腐蝕的氟橡膠或全氟橡膠。動靜環(huán)選用硬對硬(碳化鎢或碳化硅)配置。 </p> <p> 強(qiáng)酸強(qiáng)堿泵現(xiàn)場大多采用單端面密封，因而密封背面大多出現(xiàn)結(jié)晶結(jié)垢，對設(shè)備造成腐蝕等現(xiàn)象。為了避免該現(xiàn)象發(fā)生，使現(xiàn)場更加清潔，可直接選用PLAN54(見圖4)。煉油裝置中大多數(shù)酸泵或堿泵的入口壓力較低，基本為常壓，因此PLAN54 的沖洗源可直接用循環(huán)水。該方案雖然選用了雙端面密封，但從經(jīng)濟(jì)角度考慮*增加了一對摩擦副，沒有另外增加輔助系統(tǒng)，既節(jié)約了投資成本又滿足了現(xiàn)場要求。蘇州污水密封</p><p>
