摘要
文章针对某单相流体回路地面原理样机,提出采用泵变频调速技术进行控温,并对系统控温特性进行了地面试验研究,整个瞬态试验过程中控温精度一般都在±0.3℃以内,最大波动也基本不超过±0.5℃,基于泵变频调速技术的热控制策略性能优良、有效,试验结果可供实际工程设计参考。
The traditional temperature control mode using temperature-sensing valve has three deficiencies with the reliability,dynamic behavior,pump operational efficiency.In order to solve these problems,a new thermal control technology based on variable frequency pump was put forward for a fluid loop prototype model.The temperature control performance of the thermal control technology based on variable frequency pump was tested.During all transients,the controlled temperature was within the range of ±0.3℃ around the set-point,with a maximum admissible variation range of ±0.5℃.Thermal control strategy based on variable frequency pump has effective performance.
