Hydraulic pump with adjustable conveying capacity

The utility model relates to the technical field of hydraulic pumps, discloses a hydraulic pump with adjustable conveying capacity, and aims to solve the problems that when an existing hydraulic pump control valve works, a guide rod between a push rod of an electromagnet and a valve element of the control valve is prone to clamping stagnation, frictional resistance is increased, and the hysteresis characteristic of the control valve occurs. According to the scheme, the hydraulic pump comprises a hydraulic pump body, a throttling mechanism and a bottom plate, the oil pumping end of the hydraulic pump body is connected with the throttling mechanism through a liquid inlet hose, a connecting plate is fixedly installed at the bottom end of the hydraulic pump body, and a damping mechanism is installed between the bottom end of the connecting plate and the top end of the bottom plate. According to the hydraulic pump, adjustment of the conveying capacity is effectively achieved, convenience and rapidness are achieved
