液體在一定溫度下，降低壓力至該溫度下的汽化壓力時(shí)，液體便產(chǎn)生汽泡。把這種產(chǎn)生氣泡的現(xiàn)象稱為汽蝕。汽蝕時(shí)產(chǎn)生的氣泡，流動(dòng)到高壓處時(shí)，其體積減小以致破滅。這種由于壓力上升氣泡消失在液體中的現(xiàn)象稱為汽蝕潰滅。 螺桿泵在運(yùn)轉(zhuǎn)中，若其過流部分的局部區(qū)域（通常是葉輪葉片進(jìn)口稍后的某處）因?yàn)槟撤N原因，抽送液體的壓力降低到當(dāng)時(shí)溫度下的液體汽化壓力時(shí)，液體便在該處開始汽化，產(chǎn)生大量蒸汽，形成氣泡，當(dāng)含有大量氣泡的液體向前經(jīng)葉輪內(nèi)的高壓區(qū)時(shí)，氣泡周圍的高壓液體致使氣泡急劇地縮小以至破裂。在氣泡凝結(jié)破裂的同時(shí)，液體質(zhì)點(diǎn)以很高的速度填充空穴，在此瞬間產(chǎn)生很強(qiáng)烈的水擊作用，并以很高的沖擊頻率打擊金屬表面，沖擊應(yīng)力可達(dá)幾百至幾千個(gè)大氣壓，沖擊頻率可達(dá)每秒幾萬次，嚴(yán)重時(shí)會(huì)將壁厚擊穿。 在水螺桿泵中產(chǎn)生氣泡和氣泡破裂使過流部件遭受到破壞的過程就是水螺桿泵中的汽蝕過程。水螺桿泵產(chǎn)生汽蝕后除了對(duì)過流部件會(huì)產(chǎn)生破壞作用以外，還會(huì)產(chǎn)生噪聲和振動(dòng)，并導(dǎo)致螺桿泵的性能下降，嚴(yán)重時(shí)會(huì)使螺桿泵中液體中斷，不能正常工作。 螺桿泵汽蝕基本關(guān)系式 螺桿泵發(fā)生汽蝕的條件是由螺桿泵本身和吸入裝置兩方面決定的。因此，研究汽蝕發(fā)生的條件，應(yīng)從螺桿泵本身和吸入裝置雙方來考慮，螺桿泵汽蝕的基本關(guān)系式為 NPSHc≤NPSHr≤[NPSH]≤NPSHa NPSHa=NPSHr(NPSHc)——螺桿泵開始汽蝕 NPSHa NPSHa>NPSHr(NPSHc)——螺桿泵無汽蝕 式中 NPSHa——裝置汽蝕余量又叫有效汽蝕余量，越大越不易汽蝕； NPSHr——螺桿泵汽蝕余量，又叫必需的汽蝕余量或螺桿泵進(jìn)口動(dòng)壓降，越小抗汽蝕性能越好； NPSHc——臨界汽蝕余量，是指對(duì)應(yīng)螺桿泵性能下降一定值的汽蝕余量； [NPSH]——許用汽蝕余量，是確定螺桿泵使用條件用的汽蝕余量，通常取[NPSH]=（1.1～1.5）NPSHc。 裝置汽蝕余量的計(jì)算 NPSHa=Ps/ρg+Vs/2g-Pc/ρg=Pc/ρg±hg-hc-Ps/ρg 防止發(fā)生汽蝕的措施 欲防止發(fā)生汽蝕必須提高NPSHa，使NPSHa>NPSHr可防止發(fā)生汽蝕的措施如下： 1． 減小幾何吸上高度hg（或增加幾何倒灌高度）； 2． 減小吸入損失hc，為此可以設(shè)法增加管徑，盡量減小管路長(zhǎng)度，彎頭和附件等； 3． 防止長(zhǎng)時(shí)間在大流量下運(yùn)行； 4． 在同樣轉(zhuǎn)速和流量下，采用雙吸螺桿泵，因減小進(jìn)口流速、螺桿泵不易發(fā)生汽蝕； 5． 螺桿泵發(fā)生汽蝕時(shí)，應(yīng)把流量調(diào)小或降速運(yùn)行； 6． 螺桿泵吸水池的情況對(duì)螺桿泵汽蝕有重要影響； 7． 對(duì)于在苛刻條件下運(yùn)行的螺桿泵，為避免汽蝕破壞，可使用耐汽蝕材料HSND120-46三螺桿泵三螺桿泵泵業(yè)現(xiàn)貨供應(yīng)。
