離心泵汽蝕的識(shí)別汽蝕是造成離心泵的性能和效率下降的主要原因之一，及時(shí)識(shí)別出汽蝕的發(fā)生，便于采取相應(yīng)的防范措施，實(shí)際生產(chǎn)中可根據(jù)如下幾種辦法判別是否發(fā)生了汽蝕。1、根據(jù)噪音識(shí)別汽蝕發(fā)生時(shí)由于液體撞擊會(huì)產(chǎn)生各種噪聲，并且當(dāng)汽蝕嚴(yán)重時(shí)，可聽(tīng)到泵內(nèi)發(fā)出類(lèi)似于爆竹的噼噼啪啪的聲音。我們可以據(jù)此作為汽蝕的判斷。2、根據(jù)振動(dòng)識(shí)別離心泵的汽蝕伴隨著泵體的振動(dòng)，因此可以在泵體上加振動(dòng)傳感器，當(dāng)泵運(yùn)行時(shí)發(fā)現(xiàn)振動(dòng)與正常有異，應(yīng)該首先考慮是否發(fā)生了汽蝕。在實(shí)際生產(chǎn)中，我們可以根據(jù)經(jīng)驗(yàn)感覺(jué)出泵體振動(dòng)的不同，從而初步判定是否產(chǎn)生了汽蝕。廣東襯氟離心泵生產(chǎn)氟塑料化工泵哪家好，上海原孚泵業(yè)值得信賴(lài)，期待您的光臨！</p><div

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。酸堿泵哪家好，上海原孚泵業(yè)值得信賴(lài)，期待您的來(lái)電！陜西氟塑料泵批發(fā)</p><p
