Abstract

Abstract: The screw dry vacuum pump realizes multi-stage compression in one pump chamber and does not use liquid sealing, it is an excellent equipment for gas transportation under the "dual carbon" target. The article analyzes the design principles of screw dry vacuum pumps. The characteristics and requirements of screw vacuum pump in use scenarios are studied, and the particularity of vacuum system in chemical engineering is pointed out. The scene based module system integration, screw pump sealing structure, internal cooling structure and intelligent control are proposed. The database establishment and control mode optimization measures that need to be addressed in the intelligent process are discussed. It is recommended to use scenario requirements as the design principle based on theoretical design to achieve safe and efficient engineering application.
