矿用液压支架千斤顶活塞组合中密封环的研制

摘要

The seal ring for piston combination seal used in hydraulic support jack of colliery was designed. The properties and production process of seal ring were introduced. The result of crushing test shows that the piston combination seal constituted by the designed seal ring meets the requirements of the standard MT312-92.%研制一种矿用液压支架千斤顶活塞组合密封用密封环,介绍密封环的性能要求及密封环的生产工艺,采用压架试验考察由该密封环组成的活塞组合密封的性能.结果表明,由该密封环组成的活塞组合密封能够满足煤炭行业标准MT312-92要求.
