Abstract
A crude oil lifting system and a method utilizing a vane pump for conveying a fluid. The crude oil lifting system comprises: an oil pipe and an oil pump connected to the oil pipe. The oil pump is the vane pump. The vane pump is provided with a cylindrical stator. The stator has arranged therein a drive shaft and a rator sleeved onto the drive shaft. The drive shaft is arranged within the stator along the direction parallel to the length of the stator. An intake plate is arranged at the lower end of the stator. A discharge plate is arranged at the upper end of the stator. The intake plate, the discharge plate, and the stator form a cylindrical cavity. The rotor is arranged between the intake plate and the discharge plate. An intake opening for taking in the crude oil is arranged on the intake plate. A discharge opening for discharging the crude oil is arranged on the discharge plate. The method utilizing the vane pump for conveying the fluid performs lifting by taking in and discharging the fluid in the directions of the ends of the stator.
