| Abstract: | According to the investigation about valve seat of fluid end of F-1300 mud pump in field usage,approximately 80% valve seats were destroyed ahead of its design life and needed to be replaced frequently.In order to discover this failure,a contact analysis has been developed to study the interactions between valve seat,valve body and hydraulic cylinder with the FEA software in the paper.At the same time the causation of destroyed valve seat and reviewed the distribution of the stress and the strain of the valve seat was discussed.Several advices about improving the life-span of valve seat are put forward. |
