Pressurized type pressure testing pump

The invention provides a pressurized type pressure testing pump which belongs to the technical field of pumps and solves the technical problems of ultra-low pressure and difficult control of pressure and flow in the prior pressure testing pump. The pressurized type pressure testing pump comprises a water supply pipeline and a hydraulic system, wherein the water supply pipeline comprises a water pump and an ultra-high pressure container; a pipeline I and a pipeline II are arranged between the water pump and the ultra-high pressure container; a one-way valve I and a one-way valve II are arranged in the pipeline I; a one-way valve III and a one-way valve IV are arranged in the pipeline II; the hydraulic system comprises a hydraulic cylinder, a reversing valve and a hydraulic pump, and the hydraulic cylinder can transmit fluid pressure in the water pump to the ultra-high pressure container. The invention has the advantages of reasonable design, favorable pressurizing effect, large output pressure, simple operatio
