由于機(jī)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(diǎn)，因而在國(guó)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(jī)、反應(yīng)釜、攪拌器等工藝設(shè)備能否正常運(yùn)轉(zhuǎn)的關(guān)鍵部件。 </p> <p>

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(rùn)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(guò)。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(guò)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(guò)濾等措施。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="常州容積泵密封廠家"

潛污泵的作用是將污水中的雜質(zhì)通過(guò)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(guò)程中不至于發(fā)生泄露。（3）葉輪：葉輪設(shè)計(jì)成無(wú)堵塞型式，葉輪皆經(jīng)過(guò)靜平衡試驗(yàn)。葉輪材質(zhì)為HT200, 符合GB9439-88的要求，過(guò)流表面光潔無(wú)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)。
