Abstract:

由于高工况和端面间隙3~5μm,因而对端面温度的测试技术是个难点,更是研究端面微尺度热流体力学的关键点。采用LabVIEW对端面温度编写测试程序,选定符合要求的传感器等设备,确定相应的测试技术,采取抑制干扰的措施,对端面温度进行测试,研究不同工况和启停阶段下端面温度的分布和其原因。试验结果表明:不同压力和转速下,端面的温度分布:根径大于内径大于外径,最高温度发生在根径处,为90.90℃,说明非接触状态下,以根部大压降引起的热耗散所产生的温升为主。启停阶段外径温度最高,说明接触状态下,以固体壁面间摩擦产热为主。这与先前利用热耗散变形得到的理论结果相吻合,验证了根径区域为温度最高点。试验结果为今后考虑热耗散下的槽形优化提供了依据。
