輸送的液體粘稠度特別高也會導致機器不能吸上來液體,如果是因為液體粘度數值非常高,只能降低機器的轉動速度,然后提升液體的溫度,這樣就可以使液體的粘度數值降低,或者可以轉而使用立式的機器,使用設備一段時間之后不能吸收液體,很有可能是因為定子或轉子出現損壞導致的,單螺桿泵廠家建議大家及時檢查更換全新的定子或轉子。進出口子管道上面的閥門沒有開啟或開啟程度不夠,只需要開啟進出口的閥門就可以了。
B、流體粘度對工況的影響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螺桿泵的工作轉速通常為40至500r/min,為減少由于磨損而帶來的維修工作量,應當隨流體的磨蝕性增加而降低泵的轉速。研究表明,泵的磨損與流體流速成正比,但是低的轉速對井下泵的使用壽命又產生不利的影響。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.
