The Properties of Water Hydraulic High-Speed On/Off Valve Ceramic-Based
In order to solve the severe wear problem of the core in water hydraulic high-speed on/off valve, according to the requirements of high-speed on/off valve components in water hydraulic transmission and from the practical standpoint, the core manufactured with ceramic materials could bring its advantages of high strength, big hardness, good wearability, non-affection with corrosion into play.By the wear-resisting experiment the wear case of Si3N4 ceramic core has been studied with weight-loss method by electronic analysis balanc.The results show that the core manufactured with Si3N4 has high abrasion resistance and low wear rate, and the structure design of water hydraulic high-speed on/off valve with ceramic core is reasonable and the performance is good.
