Abstract
The utility model discloses a drive device of a frequency variation control plunger pump. A plunger pump oil supply drive mechanism of the prior art adopts a common motor as power, the structure is more complicated, and the oil capacity change can not be controlled in time. The drive device of the frequency variation control plunger pump adopts a drive way that a frequency variation motor directly drives a speed reducer worm and a plunger pump by a speed reducer. The drive device of the frequency variation control plunger pump comprises the frequency variation motor, the speed reducer, a coupling, a special worm speed reducer of the plunger pump and a high-pressure plunger pump and forms a drive chain of the frequency variation motor, the speed reducer, the coupling, the special worm speed reducer of the plunger pump and the high-pressure plunger pump. The utility model controls the rotating speed of the frequency variation motor by changing the frequency of the frequency variation motor to achieve the aim of controlling the oil supply capacity. The application for obtaining different oil output in different time just by designing the running program reduces cost and energy consumption.
