The invention discloses a multi-stage multipurpose hydraulic pressurizer with the variable pressurization rate. The multi-stage multipurpose hydraulic pressurizer comprises a multi-stage pressurizingstructure part, a hydraulic oil loop, a control part of the hydraulic oil loop, a pressurizing fluid loop and a control part of the pressurizing fluid loop. A multi-stage pressurizing structure comprises a hydraulic cavity, a first-stage pressurizing cavity, a second-stage pressurizing cavity and a third-stage pressurizing cavity. The hydraulic oil loop and the control part thereof comprise electromagnetic stroke limiting switches, a three-position four-way electromagnetic reversing valve, a controller, a hydraulic oil inlet and a hydraulic oil driving return opening. The pressurizing fluid loop and the control part thereof comprise one-way valves, hydraulic control one-way valves, two-position two-way electromagnetic reversing valves, a pressurizing fluid inlet, a non-pressurizing-fluid outlet and a pressurizing
