伴随着螺杆泵举升方式应用规模的日益扩大,常规地面驱动螺杆泵装置存在合理选用的问题:螺杆泵的合理选用、带泵电机的合理选用等.如果选用不当,会造成电机和螺杆泵的效率下降、能耗过大;存在安全隐患等问题.%With the growing scale of the application of the screw pump lifting way, there is a reasonable choice of conventional ground-driven screw pump device: a reasonable selection of screw pump, reasonable choice of pump motor. If the improper selection, it will cause a decline in the efficiency and large energy consumption of the motor and the screw pump; existence of security risks and other issues.
