葉輪常見的問題及處理方法A、腐蝕1.故障表現(xiàn)：選材不當(dāng)。2.處理方法：更換新葉輪，耐腐蝕磨損材料；葉輪耐蝕層的涂鍍；葉輪耐蝕層的噴涂。B、汽蝕1.故障表現(xiàn)：設(shè)計(jì)方案不當(dāng)；安裝位置過高；選材不當(dāng)?shù)取?.處理方法：降低安裝位置；改變更能夠抗汽蝕的材質(zhì)；重新設(shè)計(jì)泵型等。C、口環(huán)抱死1.故障表現(xiàn)：設(shè)計(jì)間隙過??；前后口環(huán)的硬度差小于50HBW；口環(huán)間隙有固體顆粒；口環(huán)變形等。2.處理方法：增大設(shè)計(jì)間隙；更換口環(huán)材質(zhì)；檢查工藝介質(zhì)；更換新口環(huán)等。D、斷裂1.故障表現(xiàn)：由于汽蝕、腐蝕、磨蝕引起的；鑄件質(zhì)量較差導(dǎo)致；水錘導(dǎo)致的。2.處理方法：更換新葉輪。E、鑄造缺陷1.故障表現(xiàn)：流道夾雜；多肉；不光滑；沙眼；裂紋；縮松等。2.處理方法：可根據(jù)實(shí)際情況進(jìn)行磨削、補(bǔ)焊等方法，如果問題嚴(yán)重，需打廢重鑄。F、磨蝕1.故障表現(xiàn)：由灰鑄鐵材料鑄造的流程泵葉輪在5年時(shí)間內(nèi)被含有少量水泥泡沫的水磨損的情況，磨蝕問題更多的是設(shè)計(jì)方選材不當(dāng)或泵型選擇不當(dāng)造成的，或者是工藝介質(zhì)被污染導(dǎo)致的。2，上?；け昧闶?，上?；け昧闶?處理方法：更改葉輪材質(zhì)；更改設(shè)計(jì)方案，改變泵型；檢查工藝介質(zhì)。氟塑料離心泵哪家專業(yè)，上?；け昧闶?，上海原孚泵業(yè)值得信賴，相信您的選擇，值得信賴。上?；け昧闶?/p><div

這是一種簡單易行，且在業(yè)內(nèi)得到廣泛應(yīng)用的方法。當(dāng)汽蝕發(fā)生時(shí)，離心泵的揚(yáng)程會(huì)急劇下降。API610標(biāo)準(zhǔn)中，將離心泵揚(yáng)程(對(duì)于多級(jí)泵而言是級(jí)揚(yáng)程)下降3%，作為性能斷裂的標(biāo)志，并依此判定離心泵的必需汽蝕余量NPSHr的數(shù)值。通常當(dāng)離心泵特性曲線上揚(yáng)程下跌3%時(shí)，我們認(rèn)為這個(gè)點(diǎn)是其發(fā)生汽蝕的臨界點(diǎn)，但是在泵發(fā)生汽蝕的初始階段，離心泵揚(yáng)程的變化并不是很明顯，而當(dāng)揚(yáng)程變化明顯時(shí)，汽蝕已經(jīng)發(fā)展到了一定程度，所以用揚(yáng)程來判斷離心泵的汽蝕具有一定的滯后性。河北襯氟磁力泵品牌四氟泵哪家專業(yè)，上海原孚泵業(yè)值得信賴，有需求的不要錯(cuò)過哦！</p><div

<p> b.波紋管輔助密封波紋管有輔助密封的功能。波紋管密封的特點(diǎn)就是摩擦副撓性安裝環(huán)的所有相對(duì)位移可以由彈性波紋管來補(bǔ)償，這就允許安裝摩擦副密封環(huán)有較大的偏差。不存在徑向接觸式輔助密封圈沿密封面滑移的問題。 </p><p> 化工泵電動(dòng)機(jī)維修技巧——看觀察電動(dòng)機(jī)運(yùn)行過程中有無異常，其主要表現(xiàn)為以下幾種情況。1.定子繞組短路時(shí)，可能會(huì)看到電動(dòng)機(jī)冒煙。2.電動(dòng)機(jī)嚴(yán)重過載或缺相運(yùn)行時(shí)，轉(zhuǎn)速會(huì)變慢且有較沉重的"嗡嗡"聲。3.電動(dòng)機(jī)正常運(yùn)行，但突然停止時(shí)，會(huì)看到接線松脫處冒火花;保險(xiǎn)絲熔斷或某部件被卡住等現(xiàn)象。4.若電動(dòng)機(jī)劇烈振動(dòng)，則可能是傳動(dòng)裝置被卡住或電動(dòng)機(jī)固定不良、底腳螺栓松動(dòng)等。5.若電動(dòng)機(jī)內(nèi)接觸點(diǎn)和連接處有變色、燒痕和煙跡等，則說明可能有局部過熱、導(dǎo)體連接處接觸不良或繞組燒毀等。三、電動(dòng)機(jī)維修技巧——聞通過聞電動(dòng)機(jī)的氣味也能判斷及預(yù)防故障。若發(fā)現(xiàn)有特殊的油漆味，說明電動(dòng)機(jī)內(nèi)部溫度過高;若發(fā)現(xiàn)有很重的糊味或焦臭味，則可能是絕緣層被擊穿或繞組已燒毀。氟塑料泵推薦，上海原孚泵業(yè)值得信賴。</p><div

流道式葉輪是從入口到出口是一個(gè)彎曲的流道，該類型的葉輪適用于輸送含有大顆粒雜質(zhì)或者是長纖維的液體。因?yàn)檫@個(gè)類型的葉輪具有優(yōu)良的抗堵塞性能。但是他的弊端在于抗汽蝕性能弱于其他形式的。 </p> <p> 2、螺旋離心式葉輪： </p> <p> 螺旋離心式葉輪是葉片為扭曲式的，在錐形輪轂體上從吸入口沿軸向延伸。輸送的液體流經(jīng)葉片時(shí)不會(huì)不撞擊泵內(nèi)任何部位，因此對(duì)水泵沒有什么損傷型，同時(shí)對(duì)輸送的液體也沒什么破壞性由于螺旋的推進(jìn)作用，懸浮顆粒的通過性強(qiáng)，所以采用該型式葉輪的泵適宜于抽送含有大顆粒和長纖維的介質(zhì)。化工泵推薦，上海原孚泵業(yè)值得信賴，歡迎有需求的朋友們聯(lián)系我司！河北襯氟磁力泵品牌</p><p
