通过对液力偶合器在长距离热输原油管道上应用效果的分析与计算,可以看出液力偶力器一般用于流量调节并不比阀门节流经济;而采用高效的可控硅或直流电动机-交流发电机反馈控制以及同步电动机调节在经济上是可行的。
Through the analysis and calculation of the application effect of the hydraulic coupling on the long-distance heat-transporting crude oil pipeline, it can be seen that the hydraulic power-assisted device is generally no more economical than the throttling of the flow regulation, and the efficient silicon controlled or direct current Motor-alternator feedback control and synchronous motor regulation are economically feasible.
