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.

Abstract: The system includes a robot body and a main robot control platform. The robot body includes a mechanical part and an electrical control part. The mechanical part includes a horizontal moving unit, an objective carrying platform unit and a bearing unit which are arranged in X, Y and Z cartesian coordinate directions. The objective carrying platform unit includes an objective carrying platform and a battery drive mechanism arranged on the objective carrying platform. A battery pushing mechanism is arranged on the battery drive mechanism. The electrical control part includes a data collection device connected with a main control computer system, a power drive mechanism, an I/O model and a wireless communication model I. The wireless communication model I, the wireless communication model II of a control backend and the wireless communication model III in the remote control device wirelessly communicate with each other.
