The magnetic flip is also called a magnetic flipper, which is an essential part of the display panel of the magnetic flip plate water level gauge. The magnetic flaps are regularly placed on the grooved track at certain intervals. Under the action of the internal magnetic steel balls of the flaps, the two adjacent flaps attract each other to form a stable whole. The liquid level indicator of the magnetic flat level gauge changes color due to the magnetic flip, indicating the liquid level. Therefore, the quality of the flap magnetic marbles will directly affect the stability and reliability of the flap. The flaps must work stably and reliably and cannot be separated from the relevant design requirements followed by the flaps.Generally speaking, when designing a magnetic flap, you must design and select the size of the magnetic marble, the size of the magnet, and the direction of magnetization of the flap.1. Magnetic size design of magnetic beadsThe magnetism of the flap cannot be made larger or smaller, and must be consistent with the magnetism of the surface of the buoy. Because the magnetic bead is more magnetic, the self-locking attraction between each flip is stronger, and the self-locking stability is better, but the magnetism to the wealthy is higher. This is because, for example, if the magnetism of the rich man is wrongly selected, the rich man cannot overcome the self-locking suction between flips, and the flaps cannot be flipped. I can’t be small. If it is made small, the automatic locking attraction between the flaps is insufficient, the interlocking is not good, and the flaps are inconsistent to turn over, forming a “painted face” phenomenon. Generally, ferrite magnets are used as the magnetic beads of the flaps. Ferrite magnets have weak magnetic properties and good temperature resistance, so they are suitable for the magnetic beads of the flaps.Second, the choice of the length of the magnetic beadsIf the bead size is too large, the weight of the flap will increase, the flap will be inflexible, and the sensitivity of the instrument will decrease. In addition, if the magnet beads are too large, the shape of the flap will become larger, the weight of the flap will increase, and the measurement resolution of the product will also decrease. In addition, if the flaps are spaced a certain distance, the mutual attraction of the excessively large magnetic beads to the two flaps will increase, the self-locking of the flaps will increase, and the magnetic requirements for the flaps will increase correspondingly, and the surface of the floating body needs to be larger. The magnetic field is used to flip the flaps, so if the bead size is too large, it is not conducive to flap flipping. Generally speaking, the on-site display resolution of the magnetic flip plate water level gauge is 10 mm, and the width of the flip plate is generally 8 to 9 mm, so the flip length is 5 to 7 mm and the diameter is about 3 mm. Three, the magnetization direction of the magnetic beadsWhen designing a magnetic bead, in addition to the magnetic size and magnetic pole direction of the magnetic bead, there are also requirements for the magnetic field direction of the magnetic bead and whether the central axis of the magnetic bead is inclined. After the magnetic bead is charged to the magnetic bead, the direction of the magnetic field is offset from the central axis of the magnetic bead at a certain angle. The flip of the indicator will tilt due to the direction of the magnetic field of the magnetic bead, and it becomes an integral part of the magnetic lock that cannot level each other. Generally speaking, the reason for this phenomenon is mostly due to the problem of the magnetization direction of the beads.
Therefore, the design and selection of magnetic beads are an important part of the flap design. In the research and development, Huikeda engineers conducted in-depth analysis and research on the size of the magnetic beads, the size of the magnetic field, the direction of the magnetic field and the material of the magnet, and conducted a large number of related verification experiments to make the flaps flexible and self-locking and stable. Has extremely high reliability.
