The invention relates to the technical field of diesel engines, in particular to a position control device and a diesel engine fuel pump speed regulating system. The position control device comprises a hydraulic cylinder, an adjusting mechanism and a feedback mechanism, the hydraulic cylinder comprises a cylinder body and a piston arranged in the cylinder body in a sliding mode, and the piston is used for controlling the supply flow of a fuel pump; the adjusting mechanism is used for driving the piston to slide back and forth in the cylinder body; the feedback mechanism is in communication connection with the adjusting mechanism and used for detecting the position of the piston and controlling the adjusting mechanism to drive the piston to slide or stop driving the piston according to the position information of the piston. According to the position adjusting device, the movement of the piston is controlled through the adjusting mechanism, then the position of the piston is detected through the feedback mecha
