[0033] Working principle: First, when using this device, the straight rod 1 is threaded to one end of the stator tube inside the screw pump, and the inner wall of the limiting cylinder 201 is inserted into the outer wall of the output end of the screw pump. The straight cylinder 102 can be connected to external equipment through the mounting holes on it. This is the existing technology. By connecting this device to an external controller, the controller can activate two electric actuators 301, which push two fixing plates 4, multiple connecting rods 401, and two limiting plates 5 to clamp and fix the output end of the screw pump. Simultaneously, two laser rangefinders 6 are activated to measure the distance between the output end of the screw pump and the laser rangefinders 6, thereby obtaining real-time information about the screw pump. The position and displacement information of the pump's output end serve as the basis for the controller to adjust and correct the action. When the distances measured by the two laser rangefinders 6 are equal, the output end of the screw pump is in a centered state, thereby centered the screw pump stator tube and the straight rod 1. When the measured distance on one side is greater than that on the other side, the controller can activate the two electric actuators 301 to push the two fixed plates 4 to adjust the position of the two limit plates 5, thereby correcting the position of the screw pump stator tube and the straight rod 1 and preventing the screw pump stator tube from shifting. When the screw pump stator tube drives the straight rod 1 to rotate, the multiple balls 502 can reduce the friction between the screw pump output end and the balls 502, making it easier for the screw pump stator tube to rotate.
