基于功率极限的换向阀性能与可靠性分析

Performance and Reliability Analysis of Inverter Valves Based on Power Limit

分析了阀口液动力的形成及对功率极限的影响,指出通过减少液动力可提高阀的功率极限,从而改善阀的换向性能和可靠性,使液压系统的设计更趋合理.

The formation of fluid power at the inverter valve port and its effect on power limit are analysed. The results prove that the reduction of fluid power can increase power limit and improve the invertibility and reliability of the inverter valve so as to make the hydaulic system more rational.
