The effect of asphalt pump vibration aging depends on the process selection of vibration aging. Asphalt heat pump's shape is complex, its rigidity is relatively large, its convex and concave surfaces are large, its wall thickness is uneven, its residual stress is large and its distribution is complicated. The practice experience of Beijing Octagon Oil Pump Factory over the years shows that: due to the complicated process of vibration aging, the box must be The parts are subjected to process analysis before vibration, and the vibration parameters are designed to optimize the effect of vibration aging. According to the process specification of vibration failure, the asphalt heat pump should perform process analysis before the workpiece is aged to achieve the purpose of saving energy and working time. First of all, according to the material of the workpiece, the structure, the process form and process of the blank manufacturing, analyze the distribution of the residual stress field of the box, the dimensional accuracy requirements, and the working load, possible causes of failure and other factors, and then decide to implement vibration. Timeliness of the craft line and timely focus of the site.
