YH6 6 8 1和 YH6 6 82是为新型双头铺丝机提供源动力的电液系统。我们在液化吸收国外先进技术的基础上对该系统作了进一步的研究 ,并提出了新的设计方案 ,使之更符合我国化纤工业使用状况。本装置是由电子和液压两大部分组成。这两部分互相配合完成了整个装置的试车。手动、自 YH6 6 8 1 and YH6 6 82 are electro-hydraulic systems that provide the power source for the new double-head wire-laying machine. Based on the liquefaction and absorption of advanced foreign technology, we made further research on this system and proposed a new design scheme to make it more suitable for the use of chemical fiber industry in China. The device is composed of electronic and hydraulic two major components. The two parts cooperate with each other to complete the test of the entire device. Manual, since
