Electromagnetic current amount meter With superior performance and strong stability, it is widely used in urban water supply and drainage, water treatment, environmental protection and chemical industry and other fields. Today, Yijia Xiaobian will talk about the choice of lining materials for electromagnetic flowmeter products.
1、 Ordinary rubber, natural rubber, soft rubber, hard rubber.
The operating temperature is 60 ℃, which is characterized by elasticity and good wear resistance. Generally used in urban water supply and drainage and other fields, corrosion resistance is relatively poor.
2、 Polytetrafluoroethylene, also known as PTFE, also known as F4.
One of the most commonly used lining materials, because of its stable chemical properties, is generally used for sanitary liquid or strong corrosive liquid, such as concentrated acid and concentrated alkali.
3、 Perfluoroethylene propylene, also known as F46.
This kind of material is similar to PTFE, but its wear resistance is better than that of PTFE. The temperature of the same medium can reach 100 ℃.
4、 Polyfluoroethylene, also known as FS.
It has similar characteristics with F4 material, but it bears a little lower temperature. Generally, the medium temperature is less than 80 ℃, and the cost is lower than that of F4 material.
5、 Neoprene, also known as Cr, or neoprene.
It is characterized by good wear resistance and excellent elasticity. It is generally used in water supply and drainage, sewage treatment and other fields. Corrosion resistance is a little poor, not resistant to oxidation is its disadvantage.
6、 Polyurethane rubber, also known as polyurethane.
It has excellent wear resistance, but it is insufficient for corrosivity, and the temperature should not exceed 80 ℃. It is generally used for the measurement of medium such as coal slurry, coal slurry, etc.
7、 Ceramic material
Ceramic is undoubtedly the best lining material of all electromagnetic flow meters, absolutely high-end products, the only drawback is that the price is not grounded, the production process is complex, the technical requirements are very high, and the price is very high.
Small knitting from the material characteristics and application of the above for you a comprehensive analysis of these kinds of lining, I believe that this will help you in the selection.
