液压件是机械设备重要的通用基础元件。为了加速实现机械工业“三上一提高”的战略任务,鼓励液压件厂努力生产质量好、成本低、消耗少、技术先进、经济效益高的产品,国家把液压件列入了国优产品评选项目。参加评选的创优产品,必须采用国际标准(ISO),产品质量要达到近三至五年的国际同类产品的先进水平。评选时,从主要用户单位取样,经国家级液压元件检测中心(机械部自动化所)或分中心(有关
Hydraulic parts are important general purpose mechanical components. In order to speed up the realization of the strategic task of “Three Up One Up” in the machinery industry and encourage the hydraulic parts factory to make efforts to produce the products with good quality, low cost, less consumption, advanced technology and high economic benefits, the hydraulic part has been included in the national excellent product selection project. To participate in the selection of excellent products, we must adopt the international standard (ISO), product quality to reach nearly three to five years of similar international advanced level. Selection, sampling from the main user units, the State Hydraulic Components Testing Center (Department of Mechanical Automation) or sub-centers (about
