Problems solved by technology
[0002] Most of the high-pressure injectors of MRI (magnetic resonance imaging) equipment on the market use ultrasonic motors as power modules to provide power, which has certain limitations in MRI imaging. For some high-intensity magnetic field (greater than 3T) MRI equipment imaging has certain limitations. influences
The hydraulic device in the traditional high-pressure injector directly transmits the hydraulic oil to the servo proportional valve through the oil pump, and adjusts the oil volume and oil pressure in the pipeline through the servo proportional valve. It is difficult to accurately control the flow rate and flow, so that ultra-low flow cannot be achieved. output

The invention relates to a high-pressure injection system. The high-pressure injection system comprises a high-pressure injector and a hydraulic control cabinet connected with the high-pressure injector. The hydraulic control cabinet comprises a cabinet body and a hydraulic control device arranged in the cabinet body. The hydraulic control device comprises an oil tank, a power unit, a hydraulic oil pushing mechanism and a servo driver, wherein the oil tank is used for containing hydraulic oil, the power unit is arranged on the oil tank and used for driving the hydraulic oil to flow into the high-pressure injector, the hydraulic oil pushing mechanism is arranged on the oil tank and pushes the hydraulic oil into the high-pressure injector from the oil tank, and the servo driver is connected with the hydraulic oil pushing mechanism and drives the hydraulic oil pushing mechanism to work. The hydraulic oil pushing mechanism and the power unit are connected between the high-pressure injector and the oil tank. According to the high-pressure injection system, the power unit achieving current supply is arranged outside a magnetic resonance chamber, and adverse effects on imaging of MRI equipment are avoided; the servo driver drives the hydraulic oil pushing mechanism to work, the flowing speed and quantity of the hydraulic oil can be accurately controlled especially at a low flowing speed, and ultra-low flow quantity output is achieved.
