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，蘇州水泵密封哪家比較好。柱塞泵具有結(jié)構(gòu)緊湊、效率高，蘇州水泵密封哪家比較好、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，蘇州水泵密封哪家比較好，工作室內(nèi)壓力降低，出口閥關(guān)閉，低于進(jìn)口壓力時，進(jìn)口閥打開，液體進(jìn)入；柱塞內(nèi)推時，工作室壓力升高，進(jìn)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。在密封面處由于干摩擦、冷卻水突然中斷，雜質(zhì)進(jìn)入密封面、抽空等情況下，都會導(dǎo)致環(huán)面出現(xiàn)徑向裂紋。蘇州水泵密封哪家比較好</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="蘇州水泵密封哪家比較好,封" src="https://tyunfile.71360.com/UploadFile/lscmjx/637247298179248047/5187331.jpg"></div><p> 為保證機械密封在高溫環(huán)境下正常工作，可以采取如下措施。 </p> <p> 給機封增加冷卻沖洗裝置。 </p> <p> 選擇耐高溫的材料，根據(jù)不同的工作溫度選用不同的材料。丁腈橡膠溫度上限為80℃，硅橡膠和氟橡膠為200℃，聚四氟乙烯為250℃。另外，機械密封中的非金屬摩擦副多采用石墨浸漬材料制成，所以也要根據(jù)不同的工作溫度選用不同種類的浸漬石墨。一般浸巴氏合金石墨適用溫度范圍小于150℃，浸樹脂石墨適用溫度范圍為170~200℃，浸銅、鋁、鉛的石墨可在小于400℃的工作條件下使用。動環(huán)組件應(yīng)盡可能選用膨脹系數(shù)相近的材料，以防止高溫下動環(huán)和動環(huán)座的連接松動。 </p> <p> 選擇金屬波紋管機械密封。金屬波紋管密封近年來在高溫密封中使用很多，并且取得了很好的效果。在該種機封中，金屬波紋管取代了普通機封中的彈簧，省去了動環(huán)輔助密封圈，不需要克服動環(huán)補償時與轉(zhuǎn)軸的摩擦和磨損，因此在高溫下使用，一般都能取得不錯的效果。 </p> <p> <br /> 南通離心泵密封廠家推薦設(shè)計輔助沖洗系統(tǒng)，沖洗壓力要求高于密封腔壓力，密封腔壓力要根據(jù)每種泵的結(jié)構(gòu)形式、系統(tǒng)壓力因素來計算。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="蘇州水泵密封哪家比較好,封" src="https://tyunfile.71360.com/UploadFile/lscmjx/637247295062412109/3548299.jpg"></div><p> 強酸強堿介質(zhì)具有較強的腐蝕性，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> 強酸強堿泵現(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。 </p><p> 結(jié)合設(shè)計經(jīng)驗以及對API 682標(biāo)準(zhǔn)的研究，對泵用機械密封的選型要點進(jìn)行了分析，主要包括密封類型、密封形式、布置方式、沖洗方案等。進(jìn)而對煉油裝置中的高溫?zé)嵊捅谩⒏邷責(zé)崴靡约皬娝釓妷A泵機械密封及輔助系統(tǒng)的選型提出了合理化建議，對API 682中的PLAN53B和PLAN23進(jìn)行了改進(jìn)，使之更好地為機械密封服務(wù)，有利于機械密封長期穩(wěn)定運行。 </p> <p> 由于機械密封具有密封性能好、工作可靠、泄漏量小、功率消耗少等特點，因而在國內(nèi)外煉油化工生產(chǎn)的旋轉(zhuǎn)設(shè)備中得到了較大規(guī)模的應(yīng)用，已經(jīng)成為泵、壓縮機、反應(yīng)釜、攪拌器等工藝設(shè)備能否正常運轉(zhuǎn)的關(guān)鍵部件。 </p> <p> 隨著環(huán)境保護和人類健康要求的提高，煉油裝置中對泵用機械密封的要求也在不斷提高。據(jù)統(tǒng)計，煉油裝置中機泵故障的40% 以上是由于機械密封發(fā)生泄漏而引起的。造成這一現(xiàn)象的原因，一是作為機泵中的動密封其本身所處的工作條件、起的作用所決定；二是許多國內(nèi)設(shè)計單位以及工程公司認(rèn)為機械密封及系統(tǒng)的選用是泵廠和密封廠的責(zé)任，往往對密封的類型、布置方式、沖洗方案了解不深，難以制定機械密封的選配方案，造成部分密封選型不當(dāng)。 </p> <p> <br /> 機械密封的平衡程度β也影響著密封的磨損。一般情況下，平衡程度β=75%左右**適宜。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="蘇州水泵密封哪家比較好,封"

,介質(zhì)流動通過內(nèi)外空間的交界面即密封面發(fā)生泄漏。造成泄漏的根本原因是由于接觸面上存在間隙，而接觸面兩側(cè)的壓力差、濃度差則是泄漏的推動力。由于密封面形式及加工精度等因素的影響，密封面上存在間隙在所難免，這就會造成密封面不完全吻合，從而發(fā)生泄漏。要減少泄漏，就必須使接觸面很大程度地嵌合，即減小泄漏通道的截面積，增加泄漏阻力，并使之大于泄漏推動力。 </p> <p> 對密封面施加壓緊載荷，以產(chǎn)生壓緊應(yīng) 力，可提高密封面的接觸程度，當(dāng)應(yīng)力增大到足以引起表面產(chǎn)生明顯的塑性變形時，就可以填補密封面的間隙，堵塞泄漏通道。使用墊片的目的就是利用墊片材料在壓緊載荷的作用下較容易產(chǎn)生塑性變形的特性，使之填平法蘭密封面的微小凹凸不平，從而實現(xiàn)密封。密封面合理的間隙，機械密封的平衡程度，密封端面液膜的閃蒸都是造成端面打開而使固體顆粒進(jìn)入的主要原因。鹽城化工泵用密封源頭好貨</p><p

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)補焊修復(fù)。</span> </p> <p>
