基本都是離心泵、風(fēng)機(jī)基本都是軸流式的。因?yàn)檩S流式泵在應(yīng)用中不能適應(yīng)各種不同工況下的實(shí)際要求，而且出口壓力在相同出力情況下是比較低的；一般適用于流量較大但是壓力較低的情況下使用。所以電廠的泵，除非有特殊要求，都是離心式的。而風(fēng)機(jī)一般用軸流是的（流量大，壓力要求不高）。運(yùn)行的介質(zhì)特性漿液循環(huán)泵是易損件之一，主要是受到漿液的酸性腐蝕、磨損、氣蝕，一般漿液循環(huán)泵的使用壽命3年左右，1年左右葉輪就要更換新的。1強(qiáng)磨蝕性脫硫塔底部的漿液含有大量的固體顆粒,這些固體顆粒具有很強(qiáng)的磨蝕性。2強(qiáng)腐蝕性在典型的石灰石－石膏法脫硫工藝中，一般塔底漿液的pH值為4～6屬于酸性環(huán)境；當(dāng)吸收塔內(nèi)Cl離子富集超過(guò)20000mg/L時(shí)，在低pH值條件下將產(chǎn)生強(qiáng)烈的腐蝕性。3汽蝕性在脫硫系統(tǒng)中，循環(huán)泵輸送的漿液中往往含有一定量的氣體。實(shí)際上，離心循環(huán)泵輸送的漿被為氣固液多相流，固相對(duì)泵性能的影響是連續(xù)的、均勻的，而氣相對(duì)泵的影響遠(yuǎn)比固相復(fù)雜且更難預(yù)測(cè)。當(dāng)泵輸送的液體中含有氣體時(shí)泵的流量、揚(yáng)程、效率均有所下降，含氣量越大，效率下降越快。隨著含氣量的增加，泵出現(xiàn)額外的噪聲振動(dòng)，可導(dǎo)致泵軸、軸承和密封的破壞。</p><p>
