Introduction: With the continuous development of industrial production, the requirements for flow measurement equipment are becoming higher and higher. As a common flow measurement equipment, electromagnetic flowmeter has the advantages of high measurement accuracy, good stability, and wide application range, and is widely used in various fields. In the field of corrosive medium flow measurement, anti-corrosion electromagnetic flowmeters play an important role. The lining material is a key part of the anti-corrosion electromagnetic flowmeter. Different lining materials have an important impact on the measurement accuracy and service life. Therefore, this article will study the lining materials of anti-corrosion electromagnetic flowmeters.
Main part:
1. Polytetrafluoroethylene lining material
Polytetrafluoroethylene (PTFE) is an engineering material with excellent corrosion resistance Plastic can be used stably for a long time in corrosive media such as strong acids, strong alkalis, and organic solvents. Therefore, PTFE lining materials are widely used in anti-corrosion electromagnetic flowmeters.
Performance characteristics: PTFE has corrosion resistance, wear resistance and self-lubricating properties, and is not easy to adhere to media, making it easy to clean and maintain.
Scope of application: Suitable for measuring the flow of corrosive media such as strong acids, strong alkali, organic solvents, etc.
Advantages and disadvantages: The advantages are strong corrosion resistance and long service life; the disadvantages are higher cost and lower mechanical strength.
2. Ceramic lining materials
Ceramic materials have excellent corrosion resistance and high temperature stability, so they are also widely used in anti-corrosion electromagnetic flowmeters.
Performance characteristics: Ceramics have excellent corrosion resistance and high temperature stability, and have high hardness and are not easy to wear.
Scope of application: Suitable for measuring medium flow under high temperature, high pressure, strong corrosion and other conditions.
Advantages and disadvantages: The advantages are strong corrosion resistance and good high temperature stability; the disadvantages are higher cost and greater brittleness.
3. Rubber lining material
Rubber material has good corrosion resistance and elasticity, and is also widely used in anti-corrosion electromagnetic flowmeters.
Performance characteristics: Rubber has good corrosion resistance and elasticity, is low in cost and is easy to process.
Scope of application: Suitable for measuring the flow of corrosive media such as low-concentration acids, alkalis, and salts.
Advantages and disadvantages: The advantages are low cost and easy processing; the disadvantages are relatively weak corrosion resistance and short service life.
Conclusion: The lining material of the anti-corrosion electromagnetic flowmeter has an important impact on the measurement accuracy and service life. Different lining materials have different performance characteristics and application ranges. Therefore, when selecting an anti-corrosion electromagnetic flowmeter, the appropriate internal flowmeter should be selected based on the actual working conditions.Lining material to ensure measurement accuracy and service life.
