其中一个有效的方法就是优选泵筒和柱塞的材料和表面处理工艺。
One effective way is preferred pump barrel and plunger of materials and surface treatment processes.
而泵筒下部固定泵柱塞上行时,泵筒不会发生弯曲,只是其柱塞在稠油井中下行时泵筒才会发生纵向弯曲。
The bending of pump barrel will not happen as low part fixed pumping piston going downward that only happens when it works in heavy oil well.
该模型不仅适用于柱塞与泵筒正常间隙漏失的仿真计算,也适用于非正常间隙严重漏失的计算。
This model is not only adaptable to the calculation of the leakage of the normal clearance, but also to the calculation of the severe leakage of the abnormal clearance.
