沥青泵-沥青油泵-沥青齿轮泵-沥青泵振动工艺的选择-鸿海泵业

       沥青 泵振动时效的效果取决于振动时效的工艺的选择。冶金蝶阀体，是由铸造而成的结构件，沥青 泵形状复杂，刚性相对大，凸凹面多，壁厚不均，残余应力大且分布繁杂。以前采用自然时效的工艺中存在很多的缺点，某公司自2005年开始采用振动时效工艺以来，在产品的质量和生产效率方面取得了很大的进步。多年的生产实践经验表明:由于振动时效的工艺比较复杂，必须对箱体类零件进行振前的工艺分析，设计优化振动参数以提高振动时效的效果。按照振动失效的工艺规范，沥青泵对工件时效前应进行工艺分析，以达到节约电能和工时间的目的。首先，应根据工件的材质、结构、毛坯制造的工艺形式和过程，分析箱体的残余应力场的分布，尺寸精度要求，以及工作载荷，可能的失效原因等因素进行分析，然后再决定实施振动时效的工艺线及时效重点部位。
Whether the asphalt pump vibration aging on vibration aging process selection. Metallurgy valve body, is formed by the cast structural parts, the asphalt pump complex shape, rigidity is relatively large, the convex and concave surface, uneven wall thickness, residual stress distribution of large and complex. There are many shortcomings previously used in the natural aging process, a company since 2005 since the vibration aging technology, have made great progress in quality and production efficiency of products. Years of production experience has shown that: as the VSR process is more complex, must process analysis for vibration of the front of the box type parts, design optimization of vibration parameters to improve the effect of vibration aging. According to the process of standard vibration failure, the asphalt heat pump on the workpiece process analysis should be conducted before aging, in order to save energy and time. First of all, should be based on the process of form and process of workpiece materials, structure, blank manufacturing, analysis of the residual stress distribution, the precision requirement, and the work load, are other factors may cause failure analysis, and then make a decision process line of vibration aging and aging key parts.
