【摘要】：对侧入式单端面机械密封的温度场进行了研究。通过建立二维轴对称传热的有限元模型,用有限单元法求解了机械密封环的稳态温度场,在自主设计的试验台上进一步对静环温度进行测量,得到了不同工况下的静环温度实测值。结果表明:增大弹簧比压、介质压力和转速,密封端面温度显著升高。将计算结果与实测结果进行比较,其影响趋势基本一致,误差在可接受的范围内,说明文中所介绍的计算密封环温度的方法可行,为进一步研究此类典型结构密封环的热特性提供了参考。
[Abstract]:In this paper, the temperature field of mechanical seal with side entry single face is studied. The steady temperature field of mechanical seal ring is solved by finite element method by establishing the finite element model of two-dimensional axisymmetric heat transfer. The temperature of the static ring is measured on the self-designed test rig, and the measured values of the temperature of the static ring under different working conditions are obtained. The results show that the specific pressure of the spring, the pressure of the medium and the rotational speed are increased. The result of calculation is basically consistent with the measured results, and the error is within the acceptable range. The method of calculating the temperature of seal ring introduced in the text is feasible. It provides a reference for the further study of the thermal characteristics of this kind of typical structural seal ring.
