气缸套的穴蚀是由于活塞运动而引起激振所产生的,该过程的强度可以通过相应的装置测出。MAN公司纽伦堡发动机试验站通过长期试验确定了所测信号与材料的实际穴蚀之间的相互关系。如果穴蚀发生的同时再伴有腐蚀产生,则此情况是最危险的。因此,对冷却循环系统的保养及维修提出了更高的要求,以免造成大的损坏。 Cavitation cavitation is caused by the piston movement caused by vibration, the intensity of the process can be measured by the corresponding device. MAN’s Nuremberg Engine Test Station determined through long-term tests the correlation between the measured signal and the actual cavitation of the material. This situation is most dangerous if cavitation occurs with corrosion at the same time. Therefore, the cooling system for the maintenance and repair put forward higher requirements, so as to avoid causing major damage.
