Factors affecting the reliability of flaps on magnetic flipper level gauges

The magnetic flap level gauge is based on the buoyancy and magnetic coupling principle to achieve liquid level measurement and has a very wide range of applications in industrial production. When the liquid level in the container rises and falls, the magnetic float in the float also moves up and down, and the flip of the display plate of the magnetic flip plate level flips 180° through the coupling effect of the permanent magnets in the float, at the liquid level. When it rises, the flap is flipped from white to red. When the liquid level drops, it turns from red to white. The red-white junction of the indicator is the actual height of the liquid level in the container. In fact, the accurate, stable, and reliable level indication of the magnetic flap level gauge is affected by many factors. In general, the main influencing factors are as follows:
First of all, the magnetic steel in the magnetic flap level gauge flap should have a certain magnetic. The flaps of the magnetic flap level gauge are attracted by the anisotropic between the magnets, and the characteristics of same-sex repulsion are connected with each other. This design makes the flaps work stably even under a certain vibration environment and will not appear. "Face" phenomenon.
Second, the magnetic size of the magnets in the flaps of the magnetic flap level gauge should be moderate. If the surface magnetism is strong, the interaction force between the flaps of the magnetic flap level gauge is large, and the driving force of the magnetic steel in the float to the magnetic flap level gauge flap is not enough to make the flap flip; If the interaction between the flaps of the magnetic flap level gauge is small, they cannot be interlocked, and the flaps are prone to “flower face” phenomenon in the work. Therefore, the magnetic size of the magnets in the flaps is certain. Requirements, but also to ensure that the size of the magnetic flux of each flap is the same.
Finally, flip-flop failure is a prominent problem in the working of the magnetic flip level gauge, which in turn depends on whether the processing and assembly process of the flip is in place. Rotary shaft processing is rough, surface finish is not enough, and the assembly force is used to deform the flap. Any one of the above negligence will increase the friction between the flap and the guide rail, causing the flap to turn unsteady or even snapping and unable to accurately indicate the liquid level. .

In view of the factors affecting the reliability of the magnetic flipper liquid level meter, Shenzhen R&D engineers of Shenzhen Automation Technology Co., Ltd. independently developed a series of production processes and testing standards during the product development process, effectively overcoming the defects of domestic and foreign counterparts. And common faults; and through the strengthening of the production process and details of the control of the flip, strict control of production processes and quality testing to ensure that the product has a high product performance and high reliability.
