Servo valve core testing machine

The utility model relates to a servo valve core testing machine, which comprises a casing and a controller, a testing cavity for a valve core to move horizontally is arranged in the casing, and an oil inlet and at least one oil outlet which are respectively communicated with the testing cavity are arranged on the casing. Temperature sensors and flow meters are fixedly mounted at the oil inlet and the oil outlets; and the temperature sensors and the flow meters are respectively in communication connection with the controller. The utility model has the beneficial effects that the structure is simple, the problems of heat accumulation, lubrication failure and the like formed in the high-speed movement process of the servo valve core can be tested, parameters such as a servo valve core material, a matching process, a local structure and the like are comprehensively considered, a reasonable structure and a reasonable process scheme are finally formulated through an experiment, and the quality of the servo valve co
