Research on the Design,Selection,and Modeling Technology of Circulating Fans for Natural Gas Flow Calibration Station
Due to the advantages of not relying on upstream and downstream pipeline conditions,and free switching of calibration pressure,loop calibration technology has become the mainstream development direction in the field of flow metering at home and abroad.Circulating fans are the core device of natural gas loop calibration stations,the selection and key technical parameters of the circulating fan in the loop calibration device is studied,the type of circulating fan for the calibration station is determined and a data model is built to verify whether the pressure changes can meet the calibration requirements during the operation of the circulating fan,technical support for the construction of the loop calibration station is provided.
