Generating device of servo hydraulic pump station

The utility model relates to a servo hydraulic pump station in which a frequency converter controls a servo motor to drive an oil pump, provides a generating device of a servo hydraulic pump station which has compact structure and easy control, and solves the problems of expensive cost and incapable scale industrial application and popularization in spite of superior performance of the traditional servo hydraulic pump station. The generating device comprises an oil pump, the oil pump is connected with a servo motor, a frequency converter is connected with and drives the servo motor, the speed value state parameter of the servo motor is transmitted to a logic conversion card, and the detection value state parameter of a pressure sensor is transmitted to the logic conversion card. The generating device solves the problem that the pressure instruction of the traditional servo hydraulic pump station relies on the tracking and control of a servo controller, so that a complicated servo controller software and hardware structure has to be designed, the total cost of the servo hydraulic pump station is greatly reduced, and the generating device has very high practical value and popularization significance.
