摘　　要：上游泵送机械密封是一种具有环保概念、长寿命、低能耗的高新密封技术,其应用前景将十分广阔。采用Nd:YAG灯泵浦系列脉冲激光进行了上游机械密封端面开槽加工试验,研究了激光加工工艺参数对开槽加工质量的影响。试验研究结果表明,激光电流是影响激光开槽质量的重要因素,对于硬质合金材料,激光电流为14.6A,开槽质量较高,槽深为5.5μm。这为上游泵送机械密封的理论与应用研究奠定一定试验基础。Upstream pumping mechanical seal is a kind of high-new seal technology, the features of which is the environmental protection concept, long lifetime, low energy consumption, and its application foreground will be very broad. Spiral grooves in end faces of Upstream pumping mechanical seal were processed by Nd：YAG solid laser. Influences of laser parameters on the quality of spiral grooves were analyzed. Experimental results show that the laser current is an important influent factor on the quality of spiral grooves. For Carbide materials, the laser current is 14.6A, the quality of spiral grooves is good and the depth of spiral grooves is 5.5μm. The research results are helpful for the production and application of the upstream pumping mechanical seal in the industrialization.
