The invention discloses a silencing energy-saving centrifugal machine for a pipe pile, and belongs to the technical field of centrifugal machines. The centrifugal machine comprises a control center, aservo motor, a speed reducer, a transmission shaft, a driving wheel, a driven wheel, a silencing ring, a silencing ring locking device and couplers. The servo motor, the couplers and the control center are electrically connected. The control center is connected with a wiring port of the servo motor through a data line. According to the centrifugal machine, by installing the couplers, the couplerscan meet production requirements of different pipe pile lengths through the operation characteristics of connection and excision. When the pipe pile is too long, the couplers ensure torsional rigidity through the good connection ability, thus a centrifugal technology has good transmission synchronicity in high-speed rotating, noise is reduced, and energy is saved. When acceleration is needed at the initial section of the centrifugal technology and deceleration is needed at the tail end, by means of the excision ability of all the couplers, curves of rotating rates of acceleration and deceleration pipe pile molds can be more smooth, transmission stability is improved, and the purposes of reducing the noise and saving energy are achieved.
