讲求经济效益、提高产品质量是当前改革中必须考虑的重要问题。目前国内各气动元件厂的产品,除壳体采用铝合金外,阀芯部分多数采用铜材或不锈钢材,这样是否合理、经济,看来有改革的必要。试验研究表明,采用硬质阳极氧化简称(“硬阳”)处理过的铝合金代替原用材料,不但可显著改善元件的综合性能,而且具有投资少、工艺流程简单、成本低等优点,是改变我国气动元件生产工艺落后的重要措施。下面从经济性方面作一些分析,供有关单位参考。一、设备的投资“硬阳”设备的投资,对于年处理量为24,000～50,000 dm~2(约等于4～8万根25D15的阀芯面积)的生产厂约需5.5万元左右(参见表18)。
Stressing economic benefits and improving product quality are important issues that must be considered in the current reform. At present, the products of all pneumatic components factories in our country are made of aluminum alloy except for the shell. Most of the spools are made of copper or stainless steel. Is this reasonable and economical and it seems necessary to reform? Experimental studies show that the use of hard anodized aluminum (“hard Yang”) treated aluminum instead of the original material, not only can significantly improve the overall performance of components, and has the advantages of less investment, simple process, low cost, is Changes in China’s pneumatic components of the backward production of important measures. The following from the economic aspects of some analysis, for the relevant units for reference. I. Investment in equipment The investment in “hard yang” equipment will cost about 55,000 yuan for a production plant with an annual capacity of 24,000 to 50,000 dm 2 (about 40,000 to 80,000 25D15 spools) 18).
