In order to verify the practical application effect of asynchronous motor variable frequency speed regulation in oil transportation station, the working characteristics of the variable frequency speed regulating pump (centrifugal pump), the energy analysis of the moving fluid and the power factor of the motor are analyzed. Then, the operation data of the frequency conversion centrifugal pump and non-frequency conversion (power frequency) centrifugal pump installed in series and operated at the same time in an oil transportation station are analyzed and verified. The results of theoretical analysis and statistical analysis are consistent. It is proved that the variable frequency speed regulation (frequency reduction) of asynchronous motor has remarkable energy saving effect, the oil pipeline pressure regulation range is wider, and the motor power factor is improved.
