class="title">詳細說明</p><div id="vkhzb24" class="box"><p><p> 二、螺桿泵的轉(zhuǎn)速選用 </p> <p> <br /> </p> <p> 螺桿泵的流量與轉(zhuǎn)速成線性關(guān)系，相對于低轉(zhuǎn)速的螺桿泵，高轉(zhuǎn)速的螺桿泵雖然能增加了流量和揚程，但功率明顯增大，高轉(zhuǎn)速加速了轉(zhuǎn)子與定子間的磨耗，必定使螺桿泵過早失效，而且高轉(zhuǎn)速螺桿泵的定轉(zhuǎn)子長度很短，極易磨損，因而縮短了螺桿泵的使用壽命。 </p> <p> <br /> </p> <p> 三、確保雜物不進入泵體 </p> <p> <br /> </p> <p> 濕污泥中混入的固體雜物會對螺桿泵的橡膠材質(zhì)定子造成損壞，所以確保雜物不進入泵的腔體是很重要的，正規(guī)螺桿泵廠，很多污水廠在泵前加裝了粉碎機，正規(guī)螺桿泵廠，也有的安裝格柵裝置或濾網(wǎng)，阻擋雜物進入螺桿泵，正規(guī)螺桿泵廠，對于格柵應(yīng)及時清撈以免造成堵塞。 </p> <p>
