The influence of the flipping of the magnetic flap level gauge on the accuracy and the solution

1. The influence of the flip of the magnetic flap liquid level gauge on the accuracy The magnetic flap liquid level gauge forms a connector with the liquid level gauge through the connecting pipe docked with the tank, and the principle of the buoyancy of the magnetic float, the connection between the magnetic float and the display panel On-site real-time measuring instrument for liquid level measurement based on the principle of magnetic coupling. The characteristics of the magnetic flap level gauge are very distinct, including intuitive observation, clear, non-clogging, non-leakage, convenient installation, corrosion resistance, high reliability, simple maintenance, etc. It is very suitable for various types of industrial production processes. Detection and control of the liquid level of liquid media in pressurized (or open) liquid storage equipment (towers, cylinders, tanks, spherical vessels and boilers). Magnetic flap level gauges have been widely used in electric power, petroleum, chemical industry, metallurgy, environmental protection, shipbuilding, construction, food and other industries, and the market coverage is very wide. The magnetic flap is located outside the float and is the core component of the magnetic flap level gauge. When the magnetic float in the float rises and falls with the liquid level, the magnetic steel in the float drives the magnetic flip to turn 180° through magnetic coupling, and the red and white junction of the flip is the actual height of the liquid level. Therefore, whether the flip is reliable has a great influence on whether the magnetic flip level gauge can work stably and reliably. So, what are the factors that affect the reliability of the magnetic flap level gauge? 2. The factors affecting the magnetic flip mainly include the following 2 points 1. The structure and shape of the flip a. The structure of the flip is composed of two parts that are closely interlocked with each other, and a small magnetic column is placed in the middle. The two-part structure that composes the flip sheet requires the same shape and symmetry, or the mass distribution of the overall structure after being assembled into the flip sheet is uniform. b. The shape of the flap is generally flat, rectangular or cylindrical, and the rotation requires flexibility and lightness. If the structure of the flip sheet is asymmetrical in shape and mass distribution, one side is heavy and the other side is light, which will cause the flip sheet chain to be uneven, wavy or skewed, which not only affects the appearance of the product, but also affects the seriousness of the product. The normal operation of the instrument and the liquid level indication. 2. The material of the flip sheet According to different working conditions, the magnetic flip sheet can choose different materials. At present, the materials used for processing flips on the market mainly include aluminum alloy, plastic ABS, nylon PA66 and so on. a. Aluminum alloy material. Compared with other materials, the aluminum alloy material is lighter in texture and has good temperature resistance, and is usually used under high temperature conditions; b. ABS material. The weather resistance of this material is poor, and it is prone to aging and brittle cracking in the case of sun and rain. However, its formability is good, and the flips processed by it are mostly used in indoor situations where room temperature is not exposed to sunlight for a long time; c. Nylon plastic. Due to the good temperature resistance and aging resistance of nylon plastics, it is generally used in medium-temperature or outdoor environments with sunlight. Third, the relationship between the flip and the magnetic column 1) The lighter the flip, the smaller the friction force of the flip, so in order to make the flip easier to flip, the flip should be as light as possible without affecting the overall strength of the flip ; 2) The small magnetic column in the flipping piece connects the flipping pieces of each piece into a whole through magnetic attraction and interlocking, so that the indication of the flipping piece is more stable and reliable. The heavier the weight of the flip sheet, the stronger the magnetism of the small magnetic column; the lighter the weight of the flip sheet, the weaker the magnetism of the small magnetic column (as shown in Figure 1). Figure 1 Fourth, solution guide First, after selecting a certain ferromagnetic material for making a magnetic flip, repeated trials will be carried out. Secondly, through continuous experimentation, the optimal distance between the two magnetic flips is determined. Flip material is the key factor determining the accuracy of the magnetic flip level gauge
