摘要：

A water pump volute casing was found leak after 359 hours in a 500-hour-durability bench test. The flatness of big surface, flaw detection and material strength of the pump volute casing were tested, the failure reason was identified and the structure was optimized. The fatigue life of the optimization pump volute casing was simulated by applying S-N curve method, and the optimization structure was also identified successfully by experiments.
