离心泵原理及结构（Principle and structure of centrifugal pump） This article is contributed by yangojn Ppt documents may experience poor browsing on the WAP side. It is recommended that you first select TXT, or download the source file to the local view. Principle and design of vane pump Yan Guo, Yan Yan, national command, Harbin press Catalog The fourth chapter similarity theory of vane pump cavitation and the fifth chapter sixth chapter vane pump operation characteristics and regulation of centrifugal pump impeller vane pump hydraulic design of the first chapter second chapter third chapter is the basic theory of vane pump vane pump The seventh chapter hydraulic pressure chamber and water absorption chamber hydraulic design, axial force, the eighth chapter axial force, radial force and its balance. The ninth chapter, pump shaft seal tenth chapter, axial flow pump 10 chapter, eleventh chapter, vane pump test 11 chapters Chapter 1 overview of vane pumps The working principle of pump principle and classification of 1.1 1.1.1 vane pump vane pump with liquid as the working medium, the pump is in liquid medium for work, the prime mover of the mechanical energy is converted into mechanical energy of liquid, liquid mechanical energy, volume type pump and vane pump (referred to as the vane pump and vane pump (referred to as vane pump) is the most widely used two is the most widely used two types of pumps. Class pump. In the vane pump, the vane pump, the energy conversion is between the rotor blade and the liquid medium with continuous flow around the blade, between the forces, between the blade and the liquid medium is inertial force. The force between the masses is inertia force. Figure 1-1 pump schematic 1 - 2 - 3 drain valve - pressure water chamber valve drainage pipe water pressure room 4 - 5 - 6 - foot valve impeller impeller suction pipe valve water pipe The working principle of 1.1.1 vane pump One of the basic characteristics of vane pump is different from the volume type pu
