Multi-Stage Feed Pump SolidWorks

Multi-stage feed pump is the inlet and outlet section and the middle section, which are combined together by a tie rod. His output water pressure can be very large, is a kind of centrifugal pump, also relies on the rotation of the impeller in getting centrifugal force, thus material. To be pumped out when the gas density reaches the working range of the mechanical vacuum pump, so as to gradually obtain a high vacuum. The multistage pump relies on the change of pump chamber volume to achieve suction, compression and exhaust, so it is a centrifugal pump that can change volume. The sw source file is provided.
