輸送的液體粘稠度特別高也會(huì)導(dǎo)致機(jī)器不能吸上來(lái)液體,如果是因?yàn)橐后w粘度數(shù)值非常高,只能降低機(jī)器的轉(zhuǎn)動(dòng)速度,然后提升液體的溫度,這樣就可以使液體的粘度數(shù)值降低,或者可以轉(zhuǎn)而使用立式的機(jī)器,使用設(shè)備一段時(shí)間之后不能吸收液體,很有可能是因?yàn)槎ㄗ踊蜣D(zhuǎn)子出現(xiàn)損壞導(dǎo)致的,單螺桿泵廠家建議大家及時(shí)檢查更換全新的定子或轉(zhuǎn)子。進(jìn)出口子管道上面的閥門(mén)沒(méi)有開(kāi)啟或開(kāi)啟程度不夠,只需要開(kāi)啟進(jìn)出口的閥門(mén)就可以了。
B、流體粘度對(duì)工況的影響The effect of B and fluid viscosity on the working condition隨著流體粘度的增加,由于產(chǎn)生較高的壓降使泵的排量下降。As the viscosity of the fluid increases, the displacement of the pump decreases as a result of high pressure drop.C、泵磨損影響Effect of C and pump wear螺桿泵的工作轉(zhuǎn)速通常為40至500r/min,為減少由于磨損而帶來(lái)的維修工作量,應(yīng)當(dāng)隨流體的磨蝕性增加而降低泵的轉(zhuǎn)速。研究表明,泵的磨損與流體流速成正比,但是低的轉(zhuǎn)速對(duì)井下泵的使用壽命又產(chǎn)生不利的影響。The working speed of the screw pump is usually 40 to 500r/min. In order to reduce the maintenance workload caused by wear, the speed of the pump should be reduced with the increase of the abrasive wear of the fluid. The study shows that the wear of the pump is proportional to the flow velocity of the fluid, but the low speed of the pump has a negative effect on the life of the downhole pump.
