Abstract

The cooling pump for medium and large marine engines is a centrifugal pump, which circulates the coolant to cool the engine, lubricating oil and fresh water . As the built-in engine cooling water pump uses a large amount of power compared to other auxiliary equipment driven by the engine power of a ship, proper design of components, such as the impeller, is required to improve the pump efficiency to 60% or more, and without appearance of cavitation. In this study, the impeller, volute casing, and housing that correspond to various engine specifications of marine engine manufacturers, were used. The pump installed marine engines with a total efficiency of 60% or more were designed with CFturbo S/W. Performance tests of prototypes were conducted and the results were compared and reviewed. Ultimately, high efficiency and cavitation avoidance design technology of cooling water pump were acquired.


Keywords: Cooling water pump, Centrifugal pump, High efficiency, Impeller design, Pump performance test
