Abstract:Based on the design method of great distortion and appropriate extension to pump inlet, blades of large-scale flue-gas desulphurization absorption tower circulating pump were designed to obtain more suitable blade streamline shape for fluid flow in the internal flow field, the hydro-cyclone loss and noise of pump inlet were decreased while the pump performance and efficiency were improved. An impeller clearance automatic compensation device was added to the front shroud, which ensured the pump working in high … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
