METHOD OF SETTING PERFORMANCE CHARACTERISTIC OF PUMP AND METHOD OF MANUFACTURING DIFFUSER VANE

摘要

and impeller transmission fluid to accept the fluid from the inlet toward the discharge port at the same time , the impeller and the discharge port is interposed in the flow path setting method according to the performance characteristics of the pump to change the performance characteristics of the pump provided with a diffuser 30 , the diffuser 30 and the hub 21 is provided disposed at the center of the passage, the hub (21) provided with the shroud (12) disposed about , the hub (21) and has towards the inner peripheral surface of the outer peripheral surface from the shroud 12 by a plurality of diffuser vanes arranged radially disposed (31) in , the hub 21 to the shroud 12 in an orthogonal direction orthogonal to the radial direction towards , and a positioning step of the installation set according to the performance characteristics of the installation location of each diffuser vane pump 31, which is installed on the hub (21). ;
