PLC control system study of coaxial self-vibration and variable-frequency centrifuge of tube&mould for new type well pipe

To the problem of the unchanged rotating speed of the old well pipe centrifuge, the paper firstly introduces the composing and characteristic of coaxial self-vibration and variable-frequency centrifuge of tube&mould for new type well pipe and educes the corresponding speed and time of the centrifugal molding for three stages. The control system is designed based on PLC. The actual production shows: the centrifuge has the high production efficiency and the eccentricity of well pipe produced by the centrifuge satisfies the well pipe industry standard.
