Coaxial self-vibration and variable-frequency centrifuge of tube&mould for new type well pipe is composed of variable-frequency control system, hyd raulic system, pressure device, self-vibration wheel, tube&mould, hydraulic supporting and protection device, transmission device and motor etc. Transmission device, pressure device and tube&mould is coaxial in the long distance and tube&mould is supported by the hydraulic supporting and protection device in the middle position to solve the eccentric problem of the well pipe production. The small vibration of self-vibration wheel and the variable-frequency speed regulation of electronic control are combined to improve the molding speed, density and uniformity of well pipe. Both ends of tube&mould are provided with the independent elastic clamping device and the sealing effect is good. Based on the requirement of hydraulic system of coaxial natural vibration and frequency conversion centrifuge, the mathematical model of hydraulic system is established. And then the simulation and analysis are performed by using MATLAB.
