根据Hirs理论对湍流工况下锥形密封环动力特性系数进行了数值计算,并以一台双吸泵为例分析了密封环锥度变化及磨损对临界转速的影响,从改善转子动态特性的角度对密封环最佳锥度的选择提出建议.
According to Hirs theory, the dynamic characteristic coefficient of conical seal ring under turbulent flow condition is numerically calculated. The influence of taper change of seal ring and wear on critical speed is studied by taking a double suction pump as an example. From the perspective of improving the dynamic characteristics of rotor Suggest the choice of the best taper of the seal ring.
