Magnetic flap level gauges often experience failures in the actual application process and the reasons for these failures are varied, some are caused by the failure of a single component, others are caused by the failure of multiple components at the same time.
Next, the most common faults and causes of the magnetic flap level gauge in the application process are analyzed as follows:
Fault 1. On-site display analysis of abnormal causes of a normal long-distance transmission:
In general, there are many reasons for this error, and the following are the most common reasons:
1. Resistance welding. 2. The pressure exceeds the rating, resulting in damage to the switch.
3. The glass tube reed switch for home use is fragile, and the reed switch is short-circuited or open, causing the long-distance transmission abnormality.
4. When the temperature of the medium is too high, the metal sheet will heat up and expand, and the metal contact gap of the dry reed switch is small, so it is easy to occur in the closed state.
Error 2. The remote transmission and magnetic flap do not move. This error phenomenon is usually caused by the anomaly of the float. The main phenomena are as follows:
1. Due to the incorrect design of the strength of the float, it causes it to sag inward and be deflated under pressure.
2. The weld is not penetrated or leaking, so the weld will rupture when the float is pressurized and the float enters the water.
3. The float cannot be used normally due to long-term use or demagnetization after long-term use at high temperatures.
4. Because the magnet steel in the float is loose, the float cannot work normally.
Error 3. Because the float is stuck, the reading on the display panel is inaccurate and the float in the magnetic level gauge is stuck. The most common reasons are as follows:
1. The ambient temperature is too low and the float cannot move normally due to the freezing of the medium.
2. The installation angle of the buoy is less than 87 degrees. Since the buoy is tilted, the up and down movement of the buoy will be affected.
3. The float magnetically absorbs iron filings or other debris, causing the float to get stuck and unable to move normally.
4. Due to poor sealing, the float remainsmer hanging through the infiltrated impurities, so that the swimmer can neither rise nor fall.
So-called finding the cause of the error is half the solution. Through the above analysis of the most common errors of the magnetic flap level gauge, we have basically found a way to deal with the problem and can take targeted action according to the errors and their causes.
