双吸式离心泵振动实验     

王志远  钱忠东 《实验技术与管理》2018,(4)

在水泵综合实验台上对双吸式离心泵进行了振动实验,并对实验结果进行了频谱分析,研究了不同运行工况下离心泵的振动特性。结果表明:在设计工况下,水泵轴承座轴向方向振动强度最大,主要受转子系统质量不平衡影响;径向垂直方向振动强度次之,受转子系统质量不平衡和压力脉动的共同影响;径向水平方向振动强度最小,主要受压力脉动影响;偏离设计工况下,轴承座各方向振动强度增大。该实验可为水利类及动力类专业的本科实验教学提供参考。  相似文献   

Modified surface tension model for free surface flow with single-phase lattice Boltzmann method   总被引：1，自引：0，他引：1

A single-phase lattice Boltzmann model with modified surface tension is developed in this paper to solve the problem of high-density-ratio free surface flow.The computational efficiency and accuracy are both enhanced.The restriction to the relaxation factor （which needs to be smaller than 1） is circumvented by the new surface tension algebra,due to its rational physical nature compared with the treatment of Xing,Buther and Yang in their paper （Comp.Mater.Sci.,2007,39（2）：282-290）.The proposed stable surface tension scheme is applied to simulate the free deformation of a square droplet with surface tension effect and the process of a droplet impinging on a liquid film.The numerical solution for free deformation of a droplet agrees well with thermodynamic principles,and also achieves high accuracy in comparison with Xing,et al.＇s model.Three typical impinging modes are successfully obtained with the new scheme,and another particular mode found by Wang and Chen is also successfully simulated.The evolutions of liquid crown agree well with the power law related to time.  相似文献
