The principle of vacuum pumps used for vacuum conveying: Powder conveying equipment is a type of conveying device that uses an air stream with certain energy within pipes to suspend and move granular materials from one place to another, and it separates the working gas from the materials through a separator. Vacuum conveying involves using a vacuum pump to create a pressure difference at the ends of the pipeline, thereby providing momentum to the material. It belongs to the category of high-vacuum suction conveying and is suitable for transporting materials over long distances as well as large-sized particles. Jet pumps and water ring pumps are commonly used as vacuum pumps in this process. Since the transportation of materials takes place within a closed system, no dust is generated, resulting in minimal pollution of the atmosphere. Depending on the specific requirements of the material, it is transported using nitrogen or other gases to meet its explosion-proof and other physical requirements.
