泵用機(jī)械密封的安裝和使用機(jī)械密封大多用于各種類型的泵。機(jī)械密封是一種精度較高的密封裝置，對(duì)安裝和使用條件均有一定的要求。機(jī)械密封安裝使用的一般原則弄清設(shè)備的情況，要了解設(shè)備轉(zhuǎn)軸的轉(zhuǎn)速、軸徑；設(shè)備制造精度及密封腔尺寸，設(shè)備本身的使用壽命以及設(shè)備在生產(chǎn)工藝中的地位等要做均衡的考慮。估算介質(zhì)壓力。泵的密封腔壓力一般不是泵的出口壓力，而是低于泵的出口壓力。弄清密封介質(zhì)情況。要知道密封介質(zhì)的狀態(tài)，是氣態(tài)還是液態(tài)，介質(zhì)是否含顆粒及顆粒狀況；了解介質(zhì)的性質(zhì)、溫度，以便合理選型及采取必要的冷卻、沖洗、潤滑措施。機(jī)械密封安裝使用的技術(shù)要求安裝機(jī)械密封部位的軸或軸套的徑向跳動(dòng)公差：Ф10~50mmФ50~120mm,。軸或軸套的表面粗糙度應(yīng)符合技術(shù)要求，外徑尺寸公差為h6。傳動(dòng)軸的軸向竄動(dòng)量不超過。密封腔體端面對(duì)軸表面的跳動(dòng)公差：軸或軸套外徑端面跳動(dòng)公差:Ф10~50mm，Ф50~120mm,軸或軸套的端面及密封腔體的端面要有倒角。軸徑≤Φ30mm時(shí)為3×10°，軸徑＞Φ30mm時(shí)為4×10°。當(dāng)輸送介質(zhì)溫度偏高、過低或含有雜質(zhì)顆粒、易燃、易爆、時(shí)，應(yīng)采取相應(yīng)的阻封、沖洗、冷卻、過濾等措施。蘇州化工泵用密封生產(chǎn)企業(yè)泵用機(jī)械密封經(jīng)過靜試后，運(yùn)轉(zhuǎn)時(shí)高速旋轉(zhuǎn)產(chǎn)生的離心力，會(huì)阻擋介質(zhì)的泄漏。</p><div

為減少摩擦阻力，軸上安裝機(jī)械密封的部位要薄薄地涂上一層油，以進(jìn)行潤滑，考慮到橡膠O形圈的相溶性，若不宜用油，可涂肥皂水。浮裝式靜環(huán)不帶防轉(zhuǎn)銷的結(jié)構(gòu)，不宜涂油，應(yīng)干式裝入壓蓋。 </p> <p> <span style="font-size:12px;">先將靜環(huán)與壓蓋一起裝在軸上，注意不要與軸相碰，然后將動(dòng)環(huán)組件裝入。彈簧座或傳動(dòng)座的緊定螺釘應(yīng)分幾次均勻擰緊。</span> </p> <p> 在未固定壓蓋之前，用手推補(bǔ)償環(huán)作軸向壓縮，松開后補(bǔ)償環(huán)能自動(dòng)彈回?zé)o卡滯現(xiàn)象，然后將壓蓋螺拴均勻地鎖緊。 </p><p> 泵，一種用以增加液體或氣體的壓力，使之輸送流動(dòng)的機(jī)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(dòng)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(duì)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(gè)重要裝置。它依靠柱塞在缸體中往復(fù)運(yùn)動(dòng)，使密封工作容腔的容積發(fā)生變化來實(shí)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(diǎn)，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(jī)、工程機(jī)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(dòng)驅(qū)動(dòng)，往復(fù)運(yùn)動(dòng)，其吸入和排出閥都是單向閥。當(dāng)柱塞外拉時(shí)，工作室內(nèi)壓力降低，出口閥關(guān)閉，低于進(jìn)口壓力時(shí)，進(jìn)口閥打開，液體進(jìn)入；柱塞內(nèi)推時(shí)，工作室壓力升高，進(jìn)口閥關(guān)閉，高于出口壓力時(shí)，出口閥打開，液體排出。當(dāng)傳動(dòng)軸帶動(dòng)缸體旋轉(zhuǎn)時(shí)，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(jī)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。影響密封的主要因素有哪些？密封本身質(zhì)量、工藝操作條件、裝配安裝精度、主機(jī)本身精度、密封輔助系統(tǒng)。</p><div

潛污泵的作用是將污水中的雜質(zhì)通過的方式處理。然后排放掉，與清水泵的不同之處使其技術(shù)要求也不同于普通類型的設(shè)備，它的設(shè)計(jì)需要考慮到效率、磨損以及特殊環(huán)境：（1）導(dǎo)板等部件自動(dòng)與著脫耦合，耦合牢固可靠。（2）引出電纜應(yīng)采用YZW和YCW型橡套電纜或性能相同的電纜，且電纜的密封需采用水密頭式密封，確保潛污泵在使用過程中不至于發(fā)生泄露。（3）葉輪：葉輪設(shè)計(jì)成無堵塞型式，葉輪皆經(jīng)過靜平衡試驗(yàn)。葉輪材質(zhì)為HT200, 符合GB9439-88的要求，過流表面光潔無粘砂、尖角、冷隔、氣孔、砂眼等缺點(diǎn)。（4）主軸材質(zhì)選用3Cr13經(jīng)調(diào)質(zhì)處理，有效地、可靠地傳遞動(dòng)力。主軸與葉輪用鍵連接，以傳遞動(dòng)力。主軸與葉輪用葉輪螺母鎖緊并有止退墊片，可防止水泵倒轉(zhuǎn)，造成葉輪松脫。（5）密封環(huán)：材質(zhì)鑄造青銅，防止因銹蝕而與葉輪咬死。設(shè)有密封環(huán)可更大限度地減少內(nèi)部泄露，提高水泵的效率。（6）機(jī)械密封：采用兩套單端面非平衡型機(jī)械密封。油腔和電機(jī)室之間的上部密封單元由陶瓷，石墨組成；泵殼和油腔之間的下部密封單元由碳化硅，碳化硅組成，以防接觸介質(zhì)。
