Design and Research of Vertical Multistage Barrel Condensate Pump
Vertical multistage barrel condensate pump is important equipment applied in the wide range of industry. However, the pump performances such as efficiency, net positive suction (NPSH) and reliability are not so good and could not meet the use requirements. In this paper, based on investigations of the traditional vertical multistage barrel condensate pump, some innovative design methods were proposed, which had the following main aspects: first stage wheel with an inducer praevia, the new design of hydraulic element, the innovative design of sets for seal and equilibrium of axial forces, the numerical analysis and optimum design. The experiment results show that the new designs could improve performances of the pump and meet the use requirements. The research achievement won the second prize for Science and Technology Award of Zhejiang Province.
