FRACTURE ANALYSIS OF THE SPRING OF WATER PUMPING VALVE
The springs of the water pumping valve fracture after 6 months′ service. The means,such as chemical composition analysis,metallography and scanning electron microscope etc,were used to analyse the reason of fracture. The result indicated that the corrosion fatigue fracture is the main reason of the spring fail.
