某车型发动机电子水泵卡簧失效原因分析

Failure reason analysis of electronic pump spring of engine of a certain model

相比较传统车用机械水泵,电子水泵除了结构简单外,还具有节能环保的特点。然而电子水泵在使用过程中容易出现一些故障,卡簧失效是常见故障原因之一。在问题发生后,我们应选择专用检测设备,从断口形貌、金相组织等方面进行分析和对比,找出失效原因并提出解决方法。

Compared with traditional mechanical pumps, electronic pumps have the characteristics of energy saving and environmental protection.Electronic water pump is prone to some failures during use, Snap spring failure is one of the common causes of failure. We should choose special testing equipment to analyze and compare the fracture morphology and metallographic structure.And identify the cause of the failure and propose a solution.
