3、診斷低能效井。診斷的方法是確定抽油系統(tǒng)的總效率,而確定總效率只需測(cè)量輸入原動(dòng)機(jī)的功率、測(cè)定井底生產(chǎn)壓力和精確的生產(chǎn)測(cè)試數(shù)據(jù)。一般抽油系統(tǒng)的總效率應(yīng)為50％左右,若低于此應(yīng)提高其性能。提高總效率的技術(shù)包括保持高容積效率(泵的規(guī)格與井筒注入量匹配、消除氣干擾、用抽空控制器或定時(shí)器控制抽油)和換掉過(guò)大的電動(dòng)機(jī)。 </p> <p> <br /> </p> <p> 4、井下氣分離。無(wú)效的泵運(yùn)轉(zhuǎn)常是氣干擾造成的，可通過(guò)聲波液面測(cè)量和示功圖進(jìn)行診斷。比較好是將泵吸入口置于流體進(jìn)入層段的下方，若置于上方則應(yīng)使用氣體分離器。若閥座短節(jié)布置于流體進(jìn)入層段底部以下至少10ft，則在環(huán)空中可發(fā)生有效氣分離，此時(shí)套管起分離器外筒的作用。但井的條件常不容許將泵置于流體進(jìn)入層下方，則考慮用井下氣分離器。常規(guī)的氣分離器由流體進(jìn)入部分(如射孔短節(jié))、外筒(如底部有堵頭的一節(jié)油管)和泵底部的封液管組成。湛江螺桿泵收購(gòu)價(jià)測(cè)定井底生產(chǎn)壓力和精確的生產(chǎn)測(cè)試數(shù)據(jù)。</p><div

濕污泥中混入的固體雜物會(huì)對(duì)螺桿泵的橡膠材質(zhì)定子造成損壞，所以確保雜物不進(jìn)入泵的腔體是很重要的，很多污水廠在泵前加裝了粉碎機(jī)，也有的安裝格柵裝置或?yàn)V網(wǎng)，阻擋雜物進(jìn)入螺桿泵，對(duì)于格柵應(yīng)及時(shí)清撈以免造成堵塞。 </p> <p> 四、避免斷料 </p> <p> 污泥螺桿泵決不允許在斷料的情形下運(yùn)轉(zhuǎn)，一經(jīng)發(fā)生，橡膠定子由于干磨擦，瞬間產(chǎn)生高溫而燒壞，所以，粉碎機(jī)完好，格柵暢通是污泥螺桿泵正常運(yùn)轉(zhuǎn)的必要條件之一，為此，有些螺桿泵還在泵身上安裝了斷料停機(jī)裝置，當(dāng)發(fā)生斷料時(shí)，由于螺桿泵其有自吸功能的特性，腔體內(nèi)會(huì)產(chǎn)生真空，真空裝置會(huì)使螺桿泵停止運(yùn)轉(zhuǎn)。 </p> <p> 五、保持恒定的出口壓力 </p> <p> 污泥螺桿泵是一種容積式回轉(zhuǎn)泵，當(dāng)出口端受阻以后，壓力會(huì)逐漸升高，以至于超過(guò)預(yù)定的壓力值。此時(shí)電機(jī)負(fù)荷急劇增加。傳動(dòng)機(jī)械相關(guān)零件的負(fù)載也會(huì)超出設(shè)計(jì)值，嚴(yán)重時(shí)會(huì)發(fā)生電機(jī)燒毀、傳動(dòng)零件斷裂。為了避免螺桿泵損壞，一般會(huì)在螺桿泵出口處安裝旁通溢流閥，用以穩(wěn)定出口壓力，保持泵的正常運(yùn)轉(zhuǎn)。
