Magnetic flap level gauge as the present industrial production using one of the most common liquid level measuring instrument, in the process of actual use, it is hard to avoid the happening of the fault, common fault is the magnetic flap the level of fault, due to the reason of magnetic produce beauty according to the jiangsu antell summary analysis of technical personnel, magnetic flap liquid level gauge by the force of the float can get such a conclusion, it is if the float is sucked in the liquid level switch is not can rise, along with the liquid level or increase buoyancy, either gravity or decrease magnetic attraction between the float and liquid level switch. About the two different processing methods, if increase buoyancy, float is bound to increase volume, float gravity will increase, but the float within the buoy, increased volume of allowance. And we decreased the gravity may make of the center of gravity of the float, float prone to turn, touch the ground with buoy, float weight up, can lead to inconsistent with float liquid level float magnet steel center, magnetic flap skew level gauge display. So how to reduce the magnetic attraction between the magnetic switch and the float, and we give you four options here.
(1) the first is to reduce the magnetism of the microswitch. Float with micro switch magnetic attraction also decreases, and float in the process of rising or falling, float to drive smaller, the power of the micro switch magnetic level gauge turning work will not be affected.
(2) the second is to reduce the magnetism of the float, but it will cause the board to move slowly, backward or unable to move. Because the flip of a magnetic flip is driven by the magnetic pull of the float, reducing the magnetism of the float, it also reduces the magnetic pull, which can easily cause the flip flop.
(3) the third is increasing the float and the distance of the micro switch, because of magnetic attraction is along with the distance of the magnetic materials, and increase with the decrease of the distance will also reduce the float for micro switch magnetic attraction. Concrete can be in in the buoy micro switch with iron, thicken with micro switch again after certain level, make the magnetic attraction to float just can drive the float and the gravity is not too big.
(4) a final solution is by increasing the rotation Angle of micro switch, micro switch in float under the action of magnetic force, can the rotation Angle, but because of the micro switch is limited by the limit column, the actual rotation Angle is small. After increasing the rotation Angle, micro switch magnetic column with float turn up, turn to the limit column, if the float and micro switch magnetic force is small, then the float will not force by micro switch is very big.
