Magnetic flap level indicator column display discontinuity and common solutions

With thedevelopment of modern industry, the magnetic flap level gauge (also known asmagnetic flip level gauge, magnetic column level gauge) is constantlyinnovating, its application range is more and more widely, and the models arevarious, such as top mounted type Magnetic flap level gauges, high-temperatureand high-pressure magnetic flap level gauges, anti-corrosion magnetic flaplevel gauges, outside the paste level gauge, etc., can be applied in all walksof life. The level gauge works according to the principle of buoyancy and theprinciple of magnetic coupling. When the liquid level in the tested containerrises and falls, the float in the main catheter of the liquid level gauge alsorises and falls. The permanent magnets in the float are transmitted to theon-site indicator through magnetic coupling, and the red and white columns orflaps are turned 180°. When the liquid level rises, the column or flap turnsfrom white to red. When the liquid level drops, the column or flap turns fromred to white. The red and white boundary of the indicator is the actual levelof the medium in the container. Height, thus achieving the level indication.

However,due to long-term use, it is inevitable that there will be some common faults ofthe magnetic flap level gauge.

1.Condition adjustment method: Under normal circumstances, before failure isdetermined, components in the circuit cannot be touched, especially adjustablecomponents. Unless prior steps are taken, they can be touched if necessary.Maybe after some change, the fault will be eliminated.

2. Theisolation method: that is, according to the flow chart of fault detection,segmentation and enveloping gradually narrow down the fault search scope,together with the signal comparison, parts exchange can quickly find where thefault lies. This method is relatively safe and reliable.

3:Capacitance bypass method: If the circuit has an unusual situation, you can usethis method to determine the approximate location. Observation method: that is,the use of visual, sense of smell, touch and other organs can find out wherethe level gauge fails.

4. Exclusionmethod: It is judged by inserting and removing the plug-in board and device inthe meter. If the meter recovers after removing a certain plug-in board ordevice, then the location of the fault is here.

5. Tapthe hand pressure method: When the general instrument is in good or badcondition during operation, it can be tested by this method.

Themagnetic flap level gauge is the instruments designed to measure the liquidlevel and has high measurement accuracy. As a more than 20 years manufacturerof high-risk environmental level meters, Sichuan vacorda has its ownprofessional skills and insights on level gauges. Occasionally, you will seethe beads show discontinuous, what is the reason?

1. Thereason for the external panel. After a long period of use, the gaps in themagnetic ball will accumulate dust, the magnetic properties of the ball willdegauss, the vibration of the receiving panel will be skewed, and some of theaxes of the flip will be shifted and skewed. The overturning that makes italmost impossible to synchronize with the internal dice is particularly truewhen there is more than one external panel with overturning friction.

2. Theinternal float of the jacketed magnetic flap liquid level gauge hasintermittent jamming due to internal contamination, resulting in jamming at oneliquid surface, causing the liquid surface to hold up and submerge the floater,and the floater immediately jumps out of the jam. Face, causing the externalpanel too late to react and appear red, white, red and white phenomenon, if thefloat itself adheres to more impurities, it will appear more than a point ofresistance phenomenon, the performance of the external panel is a multi-segmentred and white display.

3. Themagnetic weakening of the inner float and the increase of the external flipball friction force will also cause multi-segment display of the color of thepanel. In addition to the fixed panel material, many on-site maintenance or theuse of iron wire for magnetic ball insulation Fixed, long-lasting down causedthe magnetic appearance of the wire, causing the panel around the wire to haveonly erroneous magnetic properties, causing the red-white distribution of thepanel to appear in multiple segments.

Moreoften than not, the magnetic flap level gauge has been used for too long,resulting in loss of the flap. Of course, other situations may also occur.
