According to the process specification of vibration failure, Asphalt insulation pump Process analysis should be carried out before the aging of the workpiece to save energy and work time.
　　  The effect of the vibration aging of the asphalt insulation pump depends on the choice of the process of vibration aging. The metallurgical butterfly valve body is a structural part cast from casting. The asphalt heat preservation pump has a complicated shape, relatively large rigidity, many convex and concave surfaces, uneven wall thickness, large residual stress and complicated distribution. Firstly, according to the material and structure of the workpiece, the process form and process of the blank manufacturing, the distribution of the residual stress field of the box, the dimensional accuracy requirements, the working load, the possible failure causes and other factors should be analyzed, and then the vibration is decided. The aging process line is timely and key. Years of production practice experience shows that : due to the complexity of the process of vibration aging, it is necessary to carry out the pre-vibration process analysis of the asphalt insulation pump box parts, and optimize the vibration parameters to improve the vibration aging effect.
