The Dust Collecting Principle and Designing Method of The Pneumatic Conveying System of A Vacuum Sweeper

The pneumatic conveying system is one of the most important systems of a vacuum sweeper.The research for it is one of the key problems to design and manubacture the ma- chine.Based on the serious study of many works on pneumatic conveying system of for- eign and domestic sweeper products.This paper describes the dust collecting principle and the design method of the system.It also gives out some basic design parameters and formulations, and provides the theoretical basic for designing a dust collecting conveying system.
