| description | The leakage of metal sealing ring leak proof structure is one of the factors influencing the gas flow in leakage channel of the metal seal ring of engine. The finite element analysis software is used to establish the leakage channel model under different surface roughness,and the CFD technology is used to perform the numerical simulation of the fluid flow inside the gap of different structures to study the effect of surface roughness on the leakage flow.The leakage rate of the sealing ring is calculated,and the correctness of the calculation result is verified through the sealing test. The results show that the gas in the leakage channel is affected by the surface roughness,and the obvious backflow occurs near the rough wall surface,which can reduce the leakage flow rate of the fluid in the channel. Under the condition of constant contact stress,the leakage of the sealing gap is increased with the surface roughness. Improving the processing accuracy of the sealing ring can reduce the surface roughness so as to enhance its sealing performance. |
