| Abstract: | According to the structure of a new FAD160/40 relief valve which is developed by ZMG, in the paper the author has carried out a Hydraulic Dynamics analysis on its real application system, then constructed its mathematical model so as to test its dynamic characteristic index as the next step. The analysis has provided a detailed theory for the influence caused by the change of its key structure parameters to the system performance, and provided experience and approach for other researchers while developing a bigger flux relief valve, and has a great realistic and guiding significance to innovating the technology of coal mining equipment. |
