Abstract: To improve the dynamic seal performance of reciprocating movement, the rubber plunger with groove shape surface is designed. The dynamic sealing characteristics of the rubber plunger are analyzed and optimization experiments of the structural parameters are carried out. The results show that the groove structure can significantly increase the interfacial contact pressure, improve the interfacial lubrication condition and reduce the friction resistance. The groove structural parameters obviously influence the dynamic sealing performance of the rubber plunger. The greatest impact factor on the leakage is the groove width, the medium impact factor is the number of grooves, and the minimum impact factor is the rove spacing. To reduce the plunger leakage, the groove width and groove spacing should be designed not too big or too small. The relationship between the number of grooves and the leakage is linear, the leakage decreases as the number of grooves increases. Analysis and experiment results show that the groove structure can improve the dynamic sealing performance of the rubber plunger.

Key words: machine design, rubber plunger, dynamic seal, groove shape, leak
