該類泵的機械密封采用靜止結(jié)構(gòu)（溫度高于200℃泵采用波紋管結(jié)構(gòu)）。一是避免由于高速攪拌產(chǎn)生的熱量；二是防止彈簧傳遞扭矩。 </p> <p> 摩擦副材料的選取。 </p> <p> 對摩擦副材料的選取我們采用“WC-C”結(jié)構(gòu)。在選擇輔助密封材料時要考慮以下主要因素： </p> <p> 良好彈性，壓縮長久變形?。?</p> <p>

然而，由于環(huán)境問題的關(guān)系，采用填料密封的方法已逐漸不能被人們所接受，特別是針對現(xiàn)代工藝流程中比較普遍的、腐蝕性較強的液體而言。因此，在實際應(yīng)用中，以機械密封代替填料密封的情況越來越多。 </p> <p> <br /> 機械密封的工作溫度不能超過其規(guī)定值。</p><div style="width:100%;text-align:

泵，一種用以增加液體或氣體的壓力，使之輸送流動的機械設(shè)備。泵的種類很多，有離心泵、排污泵、柱塞泵、真空泵、蠕動泵、自吸泵等等，種類繁多。特性各不相同，應(yīng)用領(lǐng)域比較廣，應(yīng)用于農(nóng)田灌溉、排水以及工礦企業(yè)與城鎮(zhèn)的給水、排水等。那么對于各種泵的工作原理你是否了解呢？讓我們一起了解一些其中幾種泵的工作原理。 </p> <p> 柱塞泵是液壓系統(tǒng)的一個重要裝置。它依靠柱塞在缸體中往復(fù)運動，使密封工作容腔的容積發(fā)生變化來實現(xiàn)吸油、壓油。柱塞泵具有結(jié)構(gòu)緊湊、效率高、額定壓力高和流量調(diào)節(jié)方便等優(yōu)點，被***應(yīng)用于高壓、大流量和流量需要調(diào)節(jié)的場合，諸如液壓機、工程機械。 </p> <p> 柱塞泵是往復(fù)泵的一種，屬于體積泵，其柱塞靠泵軸的偏心轉(zhuǎn)動驅(qū)動，往復(fù)運動，其吸入和排出閥都是單向閥。當(dāng)柱塞外拉時，工作室內(nèi)壓力降低，出口閥關(guān)閉，低于進口壓力時，進口閥打開，液體進入；柱塞內(nèi)推時，工作室壓力升高，進口閥關(guān)閉，高于出口壓力時，出口閥打開，液體排出。當(dāng)傳動軸帶動缸體旋轉(zhuǎn)時，斜盤將柱塞從缸體中拉出或推回，完成吸排油過程。柱塞與缸孔組成的工作容腔中的油液通過配油盤分別與泵的吸、排油腔相通。變量機構(gòu)用來改變斜盤的傾角，通過調(diào)節(jié)斜盤的傾角可改變泵的排量。密封件必須避開強光照射，避免密封件被空氣中臭氧侵蝕或提早老化。常州管道泵密封哪家比較便宜</p><p style="text-indent:25px">密封件必須存放在密封包裝內(nèi)，避免和空氣中的水分或塵埃接觸。常州管道泵密封經(jīng)銷廠家</p><p> 機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械密封，與原有水泵的盤根密封形成了鮮明的對比：（1）機械密封與盤根密封在密封性能上，機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臺泵進行了進行密封改造。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，費用在7000元左右，不計人工費用每臺水泵每年消耗在2500元左右。而改為機械密封后費用方面每臺泵的機械密封價格在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。因此機械密封于盤根密封相比優(yōu)勢十分明顯。
