| 摘 要： | 风机效率和流量的准确测量对于保障风机的高效安全运行具有非常重要的作用。提出了基于热力学方法的风机效率和流量监测模型,无需测量风机的流量即可确定风机效率,可有效解决风机效率和流量在线监测的难题。该模型考虑了湿度对空气热力性质的影响,同时分别计算了轴承轴封摩擦、泄漏损失和风机壳散热等风机轴已提供但未被流体带走的外部损失,保证了模型的精度。实际计算结果表明,该模型精度高,可靠性好,可以满足工程实际需要。

| Abstract: | A mathematical model to detect the air fan efficiency in service based on thermodynamic method is established. Compared with the traditional method, the thermodynamic method can detect the fan efficiency without measuring the flow rate. The effect of atmosphere humidity on the thermodynamic properties is considered in this model. The friction between bearing and gland seal, the leakage loss and the husk heat radiation are calculated. The experimental results show that the mathematical model is valid. |
