Many studies were carried on the technologies and properties of laser cladding on the seal face of valve, but lack of contrast data with plasma spraying Alloy applied at present. In order to promote the application of laser cladding in locomotive valve, the contrast test was carried out on WF218 alloy valve. Results show that laser cladding layer has more compact, fine and uniform microstructure, as well as higher corrosion resistance and wear resistance. According to the test data, the quality of locomotive...

A theoretical model has been developed for mechanical seals with a laser-textured porous seal face. According to the basic assumptions, liquid film pressure over a pore column can characterize one over the integrated seal face. By means of variable dimensionless steps, parametric investigation has been performed to obtain dimensionless liquid film pressure by finite difference method. Meanwhile, three dimensional liquid film pressure profiles over the pore column can be achieved by computer program MATLAB. It was found from results of calculation that average liquid film pressure increases with increase of the rotational speed, liquid viscosity and reduction of liquid film thickness. Hydrodynamic effects produced by micro-pores decrease with increase of fluid pressure. In addition, the effect of pore density and depth over diameter ratio is very significant. Optimum values of these parameters can maximize the average pressure.

建立了激光加工多孔端面机械密封的流体动力学分析模型。根据基本假设,一个孔栏上的液膜压力分布可表征整个密封面上的液膜压力。将参数进行无量纲化,采用有限差分法对激光加工多孔端面机械密封进行了参数研究,并利用MATLAB计算机软件得到了无量纲液膜压力的三维分布规律。由计算分析可知,液膜平均压力随着液体粘度和转速的增加、液膜厚度的减小而增大;随着流体压力的增大,微孔产生的动压效应减弱。另外,微孔密度和微孔深径比的对液膜平均压力有很大影响,对其进行优化,可使平均液膜压力达到最大。
