摘要
Abstract
Gas Roots flowmeter is mainly used for continuous or intermittent measurement of gas flow in pipelines.The performance of flowmeter is determined by Roots rotor;and the performance of the rotor is determined by the quality of the Roots rotor profile.A new Roots rotor profile which consistsed of high-order piecewise function of polar coordinates was proposed.The coordinates of a series points of the profiles were obtained by programming;and the whole rotor profile was attained by connecting the points.An analysis and comparison of the characteristics of the new Roots profile with that of other types of Roots rotor profiles verified its superiority.关键词
