水电厂设备工作条件比较复杂,在应力、温度交替、操作方式等因素的影响下,容易出现裂缝、受损或者疲劳等问题,从而影响设备运行效果,对此,亟需采取有效措施进行修复处理。本文首先对电火花表面修复技术进行了介绍,然后结合实例,对其在水电厂设备修复中的应用进行详细探究,以期为类似工程提供借鉴。 Hydropower plant equipment working conditions are more complex, under the influence of stress, temperature alternation, operation mode and other factors, prone to cracks, damage or fatigue and other issues, thus affecting the operation of equipment, in which urgent need to take effective measures to repair treatment . In this paper, the surface repair technology of EDM is introduced first, and then with the example, its application in the equipment repair of hydropower plant is discussed in detail, with a view to providing reference for similar projects.
