AI Technical Summary
When measuring the magnetic field of a traditional magnetic levitation pump magnet, it is difficult to keep the force-bearing surface of the magnet perpendicular to the center line of the probe, which affects the accuracy of the measurement results.
An adaptive narrow-mouth magnetic levitation pump surface magnetic measurement device was designed, including a base, a support rod, and a probe. The support rod connection structure is parallel to the top surface of the base. The support rod is connected to the ball-and-socket guide cone of the magnetic levitation pump. The support rod is perpendicular to the horizontal plane by a claw and an adjustment knob, ensuring that the force-bearing surface of the magnet and the center line of the probe are always perpendicular.
This ensures that the force-bearing surface of the magnet and the center line of the probe remain perpendicular throughout the measurement process, thus improving the accuracy of the measurement results.
