在维修工程机械的液压缸时,经常可以看到液压缸缸筒内壁、活塞或活塞杆表面有一些蜂窝状的孔穴,这都是气蚀所致。气蚀会导致缸筒与活塞杆的配合表面变得粗糙,液压缸产生内泄,工作速度下降。当气蚀与其他形式的腐蚀共同作用时,将会加速液压缸主要零件 In the maintenance of construction machinery hydraulic cylinder, you can often see the cylinder wall cylinder, piston or piston rod surface has some honeycomb-shaped cavities, which are caused by cavitation. Cavitation can cause the mating surfaces of the cylinder barrel and the piston rod to become rough, the hydraulic cylinder generates internal leakage, and the working speed decreases. When cavitation interacts with other forms of corrosion, the hydraulic cylinder will accelerate major components
