螺桿泵由于其結(jié)構(gòu)特點(diǎn)，大部分使用在輸送較高粘度的液體及含有顆粒的液體，因此其轉(zhuǎn)數(shù)的選擇非常關(guān)鍵，螺桿泵零件少，結(jié)構(gòu)緊湊，體積小，維修簡單，螺桿泵轉(zhuǎn)子和定子是螺桿泵的易損件，結(jié)構(gòu)簡單，便于裝拆。是按迥轉(zhuǎn)嚙合容積式原理工作的新型泵種。主要工作部件是偏心螺桿（轉(zhuǎn)子）和固定的襯套（定子）。采用***無味的食用橡膠，工作溫度可達(dá)120攝氏度，如果采用高溫120攝氏度—350攝氏度時(shí)可定制。由于該二部件的特殊幾何開頭分別形成單獨(dú)的密封容腔。介質(zhì)由軸向均勻推行流動(dòng)。內(nèi)部流速代低，容積保持不變。螺桿泵壓力穩(wěn)定，因而不會(huì)產(chǎn)品渦流和攪動(dòng)。每級(jí)泵的輸出壓力為0.6MPa—1.2MPa，揚(yáng)程60m—120m（清水），自吸高度一般在3m以上。 </p> <p> 螺桿泵如何保持高效率 </p> <p> 如何保持螺桿泵高效率，螺桿泵的容量大于井的產(chǎn)量或泵吸入口處氣分離不好，一部分泵排量受氣干擾而損失，如果消除泵內(nèi)氣的干擾和控制泵的運(yùn)轉(zhuǎn)時(shí)間，使泵排量與流入井底的液量相匹配，就可以提高效率和降低成本。 </p> <p> <br />

</p> <p> <br /> </p> <p> <br /> </p> <p> （2）打開放氣旋塞，向水螺桿泵內(nèi)灌水，同時(shí)用手轉(zhuǎn)動(dòng)聯(lián)軸器，使葉輪內(nèi)殘存的空氣盡可能排出，直至放氣旋塞有水冒出時(shí)，再將其關(guān)閉； </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> （3）大型水螺桿泵用真空螺桿泵抽氣灌水時(shí)，應(yīng)關(guān)閉放氣旋塞及真空表和壓力表的旋塞，以保護(hù)儀表的準(zhǔn)確性。 3.啟動(dòng) </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 完成以上準(zhǔn)備工作后，便可啟動(dòng)螺桿泵。啟動(dòng)后待水螺桿泵轉(zhuǎn)速穩(wěn)定，電流表指針擺動(dòng)到指定位置，這時(shí)再把真空表及壓力表的旋塞打開，并慢慢開啟出口閥門，水螺桿泵進(jìn)人正常運(yùn)行。與此同時(shí)還應(yīng)將水封管的閥門打開。 </p> <p> <br /> </p> <p> <br /> </p>
