Electromagnetic flowmeter material selection guide- strong wear series
Electromagnetic flowmeter measurement type conductive grout medium is more common in the industry, the ore smelting industry, in particular, under the condition of this condition, usually measured medium solid-liquid mixture is more, the electromagnetic flow sensor pipe has certain wear and tear. Pulp, for example, has a strong wear, based on the lining of the electromagnetic flowmeter under the condition of the electrodes and the material of choice for simple introduction.
The lining part:
The preferred polyurethane rubber, smooth; Resistance to solvent, oil and grease; Has excellent abrasion resistance (equivalent to ten times the natural rubber); Medium temperature 0 ℃ to 50 ℃; Suitable for sand, silt, strong wear of slurry, coal slurry and the mud, and other wear particles; For many liquid chemical corrosion of acid, alkali ability is bad, can not be used in the liquid mixed with organic solvents.
Then is neoprene, has good elasticity, high break strength, good abrasion resistance, medium temperature of 80 ℃ ~ 120 ℃ is need special order, commonly used in water, sewage, wear soft mud and slurry. Also generally low concentration acid, alkali, salt medium corrosion and oxidation resistance of medium corrosion.
There is a natural rubber, also known as soft rubber, medium temperature resistant to 0 ℃ ~ 70 ℃, good abrasion resistance, especially suitable for sand, silt and particles.
Electrode parts:
Electrode material depending on the degree of wear medium, generally recommend choose "stainless steel coated with tungsten carbide material, strong wear resistance type medium, if no measured medium corrosion. Other also can choose titanium (Ti), tantalum (Ta), but higher relative prices higher than the former.
Above is the media has a strong wear series of material selection. Finally, the four kinds of characteristics of the measured medium, about electromagnetic flowmeter lining and detailed instructions are included in the selection of electrode material after all, the above series for your reference in the electromagnetic flowmeter selection!
