這是一種簡(jiǎn)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(lái)判斷離心泵的汽蝕具有一定的滯后性。 </p><p> 汽蝕的危害汽蝕會(huì)影響離心泵的正常運(yùn)行，引發(fā)許多嚴(yán)重后果。汽蝕致使泵產(chǎn)生噪音與振動(dòng)當(dāng)發(fā)生汽蝕時(shí)，高頻的液體相互撞擊會(huì)產(chǎn)生各種噪音，嚴(yán)重時(shí)泵內(nèi)會(huì)發(fā)出噼噼啪啪的聲，同時(shí)誘發(fā)泵機(jī)組的振動(dòng)，而泵機(jī)組的振動(dòng)又會(huì)加速氣泡的產(chǎn)生與破裂。當(dāng)液擊的頻率與泵機(jī)組的固有頻率相同時(shí)，就會(huì)發(fā)生強(qiáng)烈的汽蝕共振，使振幅迅速增大，此時(shí)若要保護(hù)離心泵不會(huì)發(fā)生更大的破壞，就必須立即停車檢查。汽蝕制約了離心泵的發(fā)展隨著科技不斷進(jìn)步，現(xiàn)代化工業(yè)要求離心泵要向大流量和高揚(yáng)程發(fā)展，這就需要提高介質(zhì)的流速，根據(jù)流體力學(xué)，液體流速越高，入口壓力損失越大，更加容易產(chǎn)生汽蝕。因此，提高泵抗汽蝕性能，研究汽蝕機(jī)理，是離心泵發(fā)展中的重要研究課題。氟塑料離心泵哪家專業(yè)，上海原孚泵業(yè)值得信賴，還等什么，快來(lái)call我司吧！</p><div
