YJ-UHZ series Magnetic level gauge It is a kind of liquid level measuring instrument which is widely used in our industrial production. It shows the liquid level by many magnetic turnover plates in the magnetic flap indicator. But in our actual use, these magnetic flap sometimes appear disorderly arrangement, turning plate disorderly and so on, which makes the magnetic flap liquid level meter lose its function of liquid level measurement. For its reason, Yijia small editor also made in-depth research, asked professional magnetic flap level meter engineer, the basic conclusion is as follows.
First, the vibration of the application site is large
If the field vibration is large, when the vibration force overcomes the self-locking force between the magnetic flip sheets, the magnetic flip sheets will easily turn over. In view of the above factors leading to irregular arrangement of magnetic flip sheets, automation technicians have conducted a lot of targeted tests to determine the best performance of magnets.
one When selecting magnets, magnets with small temperature coefficient and high temperature resistance are used to make magnetic floats;
two To find qualified magnet suppliers, strengthen the inspection and control of magnet quality, and select magnets with stable quality;
three Remind users to avoid installing the magnetic flap level gauge in the environment with high vibration.
Second, the quality of magnetic beads in the magnetic flap is unqualified
If the magnetic field direction of the magnetic bead is inclined when the magnetic impact is handled by the manufacturer, there will be a certain angle deviation from the central axis of the magnetic bead or the magnetic property will be insufficient. When the magnetic turnover plate with magnetic beads is placed on the guide rail frame, the phenomenon of irregular inclination will occur. When the indicator is affected by the magnetic float moving up and down, it will turn the plate randomly, which will affect the normal indication of the liquid level meter.
Thirdly, the magnetic stability of the magnetic steel in the magnetic float directly affects the stability of the magnetic flap
This is because the magnetic flap level gauge uses the magnetic coupling principle to measure the liquid level. Therefore, the magnetic stability of magnetic steel in maglev train will directly affect the normal rotation of magnetic flap. Generally speaking, the magnetic properties of maglev train and magnetic flap are greatly affected by service life and service environment.
one When the service life of the magnetic float is longer or the service temperature exceeds the maximum service temperature that the magnetic steel can bear, the magnetism of the magnetic steel in the float will be reduced or demagnetized, and the magnetic coupling ability of the float will be reduced. The magnetic flap can not be driven to turn over, or only some magnetic flip plates will turn over;
two If the service life of the magnetic flap is longer, the magnetism of the magnetic bead inside the magnetic flap will decrease or demagnetize, and the self-locking force between the magnetic flap will also decrease, which will lead to the shaking and random overturning of the magnetic flap.
