A high pressure pump, provided with a plurality of an eccentric wheel on the main shaft, the eccentric wheel group consists of a number of eccentric wheel arranged in the axial direction along the axis of the circle, each of the major diameter of the eccentric vertex successively along a spindle for the center of the uniform; in each of the eccentric wheel is arranged around the piston to pump less a pair of diametrically opposite, each of the cylinder piston pump installed in the base, the piston push rod and the outer end of the plunger pump through a guide sleeve is arranged in a wheel, the eccentric wheel of the outer circumference of the roller with the outer peripheral surface of a corresponding surface offset with a water supply pipeline interface; and the drainage pipe interface in piston pump; spindle connected via the transmission mechanism and the power device. The advantages are: the development of engineering for oil drilling, drilling and cementing fracturing can increase drilling speed, shorten the drilling cycle, reduce cost; high pump pressure and uniform stability, repair work can not stop the pump, and improves the service life.
