離心泵機(jī)械密封失效的分析 </p> <p> 離心泵停機(jī)主要是由機(jī)械密封的失效造成的。失效的表現(xiàn)大都是泄漏，泄漏原因有以下幾種： </p> <p> 動(dòng)靜環(huán)密封面的泄漏，原因主要有：端面平面度，粗糙度未達(dá)到要求，或表面有劃傷；端面間有顆粒物質(zhì)，造成兩端面不能同樣運(yùn)行；安裝不到位，方式不正確。 </p> <p> 補(bǔ)償環(huán)密封圈泄漏，原因主要有：壓蓋變形，預(yù)緊力不均勻；安裝不正確；密封圈質(zhì)量不符合標(biāo)準(zhǔn)；密封圈選型不對(duì)。 </p> <p> <br /> </p> <p> 液體介質(zhì)潤(rùn)滑性較差，加之操作壓力過(guò)載，兩密封面追蹤轉(zhuǎn)動(dòng)不同步。例如高轉(zhuǎn)速泵轉(zhuǎn)速為20445r/min，密封面中心直徑為7cm，泵運(yùn)轉(zhuǎn)后其線速度高達(dá)75 m/s，當(dāng)有一個(gè)密封面滯后不能追蹤旋轉(zhuǎn)，瞬時(shí)高溫造成密封面損壞。 </p> <p>

將需要增加NPSH或排空現(xiàn)有系統(tǒng)內(nèi)的攜入空氣。c.腐蝕和沖蝕——雖然腐蝕和沖蝕問(wèn)題極易被視為"內(nèi)部問(wèn)題"，但是其根源在于為泵的抽送能力選擇材料時(shí)的不當(dāng)。腐蝕或沖蝕產(chǎn)生的損壞可能毀壞葉輪或頸環(huán)，導(dǎo)致機(jī)械的振動(dòng)超出限度。需分析泵的抽送能力才能解決這一問(wèn)題。即使受沙礫沖蝕較厲害，仍需按照步驟更換材料以根除問(wèn)題或延長(zhǎng)MTBF。d.葉輪的不平衡——按照ISO標(biāo)準(zhǔn)1940/1，葉輪應(yīng)該切割到大運(yùn)行速度時(shí)的恰當(dāng)直徑并實(shí)現(xiàn)動(dòng)態(tài)平衡()，該平衡級(jí)允許轉(zhuǎn)速為1800時(shí)每盎司泵輪重量產(chǎn)生(轉(zhuǎn)速為3600時(shí)為)。如果在現(xiàn)有泵上切割葉輪，按照標(biāo)準(zhǔn)平衡葉輪時(shí)出現(xiàn)初始故障或重新平衡失敗將導(dǎo)致振動(dòng)超出可接受的范圍。這一點(diǎn)在各種大、小機(jī)械上均很重要，因?yàn)橐呀⒌臉?biāo)準(zhǔn)考慮了機(jī)械的總質(zhì)量以及葉輪對(duì)振動(dòng)產(chǎn)生的影響。的解決方法是拆掉葉輪重新進(jìn)行平衡。e.電動(dòng)機(jī)轉(zhuǎn)動(dòng)元件的不平衡——這是一種少見(jiàn)的制造缺點(diǎn)。有關(guān)電動(dòng)機(jī)平衡測(cè)試要求請(qǐng)見(jiàn)美國(guó)電氣制造業(yè)協(xié)會(huì)(NEMA)的標(biāo)準(zhǔn)MG-12007第1節(jié)第7部分。通常情況下，被確定為電動(dòng)機(jī)轉(zhuǎn)子不平衡(通過(guò)斷開(kāi)電動(dòng)機(jī)并由其自行運(yùn)轉(zhuǎn))的問(wèn)題實(shí)際上是曲軸或軸承故障問(wèn)題，該內(nèi)容已在本文其他部分進(jìn)行討論。電動(dòng)機(jī)旋轉(zhuǎn)部分的不平衡實(shí)際上在啟動(dòng)時(shí)。離心泵廠家供應(yīng)就找靖江市瑞鑫泵業(yè)有限公司。南通自吸泵離心泵銷售</p><p

是一種較快的止回閥；多瓣旋啟式止回閥適用與大口徑管路.2.泵出口止回閥的安裝①旋啟式止回閥一般安裝在水平管道上：對(duì)于口徑DN~80mm的止回閥，也可安裝在垂直或向上傾斜的管道上。②直通式升降式止回閥應(yīng)安裝在水平管道上；立式升降式止回閥必須安裝在垂直管道上，介質(zhì)為自下而上流動(dòng)。③由于止回閥容易損壞，因此，應(yīng)靠近泵出口安裝止回閥，在止回閥上部設(shè)有切斷閥(一般用球閥或閘閥)，方便檢修。④為便于止回閥拆卸前泄壓，對(duì)于止回閥本身不帶放凈閥的，應(yīng)在止回閥與切斷閥之間加裝泄壓用放凈閥。3.防止水力沖擊對(duì)止回閥密封面損壞的保護(hù)措施止回閥的設(shè)置,起到了防止物料倒流，避免泵葉輪遭受液擊的作用。但就止回閥本身而言,設(shè)置不當(dāng),會(huì)造成水擊所產(chǎn)生的閥瓣對(duì)閥座的突然撞擊，損及止回閥密封面。因此，應(yīng)采取以幾點(diǎn)保護(hù)措施。1、對(duì)于泵出口設(shè)置>80mm的旋啟式止回閥，應(yīng)采用水平安裝方式，以減弱閥瓣回座及產(chǎn)生的撞擊。2、對(duì)于泵出口止回閥口徑>=150mm的管路，應(yīng)在止回閥前后設(shè)置旁路，防止閥前壓力上升過(guò)高，對(duì)止回閥密封面造成的損害。3、對(duì)泵排出管路起點(diǎn)和終點(diǎn)壓力較高管路，不允許設(shè)置旁路的，可采取以下措施。設(shè)置安全閥以代替旁路閥。其作用與旁路閥相似。南通自吸泵離心泵銷售</p><p
