对于机械液压式燃油调节系统来说,精密活门偶件的灵活性、分油槽边的尖边质量、活门重叠量配磨准确性等关键指标的优劣直接决定了系统调节精度和工作的稳定性和一致性。高、低压控制活门尺寸公差、形为公差、粗糙度、滑阀副配合间隙要求较高。因此,现有的加工和检测方法不同程度地存在一些技术和能力方面的不足。
For the mechanical hydraulic fuel regulation system, the flexibility of precision valve couplings, the sharp edge of the sub-tank edge quality, the amount of overlapping valve with the grinding accuracy and other key indicators of the merits of a direct decision of the system to adjust the accuracy and stability of the work And consistency. High and low pressure control valve size tolerances, shaped as tolerances, roughness, sliding valve deputy with higher clearance requirements. Therefore, the existing processing and testing methods have some technical and capacity deficiencies to varying degrees.
