Magnetic flap level gauge components damage failure and treatment:
Magnetic flap level gauge in the practical application of often failure, of these failures, some caused by a single component failure, some caused by simultaneous failure of multiple components. Magnetic flap level gauge common fault and its causes are as follows:
A: The display panel is abnormal
The reasons for this failure are usually the following:
1, the gap between the flap and the guideway design unreasonable or too small, resulting in friction is too large, the flip does not flip;
2, the distance between the display panel and the buoy is too large, the magnetic drive force of the buoy is insufficient, which causes the flip not to flip;
3, the magnet in the flip is too small or the magnetic force disappears, resulting in flip does not flip or flip abnormalities;
4, water or dust and other impurities infiltrated the display panel, resulting in flip flip difficult;
5, the ambient temperature is too low, causing the media to freeze, the float can not move, flip the liquid level can not be displayed properly.
Second: the local show normal, remote display is not normal
In general, there are several common reasons for this failure:
1, domestic reed pipe glass fragile, reed pipe short circuit or open, will lead to abnormal remote transmission;
2, resistance Weld;
3, the reed switch metal contact gap is very small, when the medium temperature is too high, the sheet metal when heated expansion, prone to closed state;
4, the pressure exceeds the rating, resulting in switch damage.
Three: remote and magnetic flap are not moving
This failure phenomenon is usually caused by abnormal floats, the following two kinds of performance:
Phenomenon one: the float is stuck, resulting in the display panel instructions are not correct.
Failure Analysis: Floating magnetic flap level gauge stuck, usually for the following reasons:
1, when the float used for a period of time, the float may be stuck due to the presence of impurities, can not rise or fall;
2, buoy installation angle is less than 87 degrees, leading to tilt, affect the float up and down movement;
3, the float due to its own magnetic adsorption of iron or other dirt caused by stuck;
4, the ambient temperature is too low, causing the media to freeze, the float can not move.
Phenomenon two: Float damage, resulting in the display panel instructions are not correct.
Failure Analysis: Floating magnetic level gauge floater damage, usually for the following reasons:
1, the float due to the strength of the design is wrong, resulting in pressure to the inside of the depression, deflated;
2, no welding penetration or welding at the weld, resulting in pressure when the weld cracks, floats into the water;
3, the float due to the use of a long time or long-term high temperature use, demagnetization, resulting in unusable;
4, the float in the magnet loose, resulting in the float can not work.
