液压泵总功率控制的均压阀

摘要

The design and practical use of the hydraulic system, the two variable piston pump together in the same hydraulic system and to ensure consistency and to achieve the two hydraulic displacement of the total power control. The general use of two cross-pump control mode, the disadvantage is that the two hydraulic control cross consistency and total power control is poor, and it is difficult to ensure the con-sistency of the two hydraulic pumps. In this paper, by designing a pressure equalization valve to achieve the two hydraulic control. The re-sults showed that the equalizing valve can well ensure the consistency of the two hydraulic pumps and total power control.%在液压系统的设计和实际使用过程中,两台变量柱塞液压泵共同作用于同一液压系统并保证两台液压泵排量一致且要实现总功率控制.目前一般采用两台液压泵交叉控制的方式,交叉控制的缺点是两台液压泵的一致性和总功率控制效果差,且很难保证两台液压泵的一致性.该文通过设计一种均压阀,来实现两台液压泵的控制.结果表明,均压阀能够很好地保证两台液压泵的一致性和总功率控制.
